Best power inverter 2018 – [Buyer’s Guide]Last Updated May 1, 2020
Best power inverter of 2018
So, what exactly would anyone want to know about power inverter? I know most of us don’t really care much about the history and the origin, all we want to know is which of them is the best. Of course, I will spare you the history and go straight on to the best power inverter. Here we have compiled a detailed list of some of the best power inverter of the 2018.
Not all power inverter are created equal though. Many models on the market may be confusing to a person who is shopping for their first time.
Test Results and Ratings

power inverter Buyer’s Guide
Sometimes bigger is not better. What we really need to know is what percentage of the power that goes into the inverter from the battery comes out the other side as AC power. To make this calculation even more difficult, the efficiency of an inverter changes with the output load placed on it. if a small load is put on an inverter it may be only around 50% efficient. However increase the load to near the inverters stated maximum continuous load and the efficiency will rise to around 90%.
Practically this means that you coud run your 20 Watt appliance for much longer on the same battery by choosing to use the 150 Watt inverter rather than the 3000 inverter.

It will shut down in case there is a power overload, short-circuiting and other thermal problems.
Let Us First Understand Your Power Requirement
One of the most important thing that you must know before buying an inverter is your “power requirement”. In simple words- what all home appliances (like lights, fans, televisions, or any other appliances) you will run at the time of power cut. Power requirement is an addition of the power consumed by various electrical home appliances.
Find the VA Rating of the Inverter You Need
VA stands for Volt ampere rating. It is the voltage and current supplied by the inverter to the equipment. Your appliances need more VA than the power requirement in Watts due to the nature of the devices. The ratio is called Power factor.
Hence Power supplied (or VA rating of inverter) = Power requirement (power consumed by equipment in watts) / Power factor.
Single Battery or Double Battery
Now suppose your power back up requirement is hrs for the same power load.
Battery Capacity required = (851*4) / 1= 28Ah ~ 300Ah
Since batteries are available between 60-200Ah, you will need battery of 150Ah (in series) to provide 300 Ah. Two batteries together create 2V output, hence you need to choose inverter which supports 24V input.
Foval 150W Car Power Inverter
When you are travelling, then this is an ultimate charger that you need to take care of your charging problems. It is an easy to use charger because you need to simply plug the inverter into the vehicles lighter so that you have the best convenient charging while you are on the road. You can use this item in different places so that you have the convenience of its use.
It has been made from materials that are durable and luckily, installed with the perfect color that will fit into any car décor that you will put it in. when you are not using it, you can take it or store it in the glove compartment. It is also usable to charge a variety of mobile devices safely. When you want to use it, just plug it in and it is ready to start charging your devices.
How to choose an inverter
Inverter for use at home has become a necessity than a luxury with frequent power cuts across India. The sales of popular brands like APC, Luminous, Sukam, Microtek, Amaron, V guard, Hykon with good reviews have been zooming even though the prices have been rising. People now want to run all home appliances including air conditioners, televisions and refrigerators for their convenience.
Solar Power Support
Inverter today also support solar power system. They convert DC power generated by solar panels and store it in batteries. These get transformed to power which can be used for home appliances. These systems can be can be expensive and hence might not be advisable for individual homes.
DIFFERENCE BETWEEN INVERTER AND UPS
Both provide backup when there is a power outage. In case of UPS the switch is instantaneous whereas in case of inverters there is a lag in switch.
Hence in case of critical applications like computers a UPS is needed.
For household appliances like fan, light, cooler etc. the gap is fine and hence an inverter works well.
Volts x Amps = Watts
The sum of wattage of all appliance should be within the specifications of the inverter. e.g. if you are planning a outlet inverter then take the sum of wattage and add another 50% to account for any surges in power draw. For example if your tubelight draws 50W and fan draws 50W you should go for at least a 150W ( 50W+50W+50% of (50W+50W) ) inverter.
Make sure the power of the inverter is listed as “continuous”. They should not draw the wattage for a short period of time and then will shut off, reset themselves and resume functioning. Such outages can be frustrating and harmful to the appliances.
True Sine Wave
True sine wave inverters are the most expensive. They deliver the most consistent, highest quality wave output.
These can have high surge capacity which indicates that they can exceed the rated wattage for limited time which is helpful in starting appliances.
Some equipment requires a true sine wave like laptops, battery chargers and so on. AC appliances will run on a true sine wave inverter.

Pika Energy devices are fast and simple to install and commission and offer extremely high roundtrip efficiency to maximize the customer’s lifetime energy yield and cost savings.
Differences Between Inverter and UPS
A UPS (Uninterrupted Power Service) also converts DC to AC, but the switching over time in such devices is much faster. An inverter will take at least 100 milli seconds to switch from grid power to battery power, when power fails. This is acceptable in case of basic simple appliances like lights and fans, but if a desktop is connected to the inverter, you will lose data until the backup kicks in. A UPS, on the other hand, takes mere 3-milli seconds, thus ensuring critical support and minimum damage to your sensitive electronic devices.
There is a difference between peak load and continuous load. Peak load is the maximum load that inverter can handle, usually only for short amount of time (few seconds). Continuous load is generally advertised and it means how much it can run normally.
This is mostly the feature of better and more expensive inverters. In case you plugged them in too high powered device, they automatically adapt. Some power inverters could blow up in this case, so it is very important to have the protection.
Of course in the end you also have to look at the cost. Naturally with more features the price will increase. In this guide we will review some of the best pure sine power inverters. They are the best based on the price for which you are buying them.
This power inverter is 600 watts power inverter. It has aluminum case which will provide a good longevity of this product. In case it falls somewhere, it should still work.

It has an attractive price point and a built-in thermos cooling fan. Although it does not have many features, it is still quite a good power inverter for the price. It can be used in variety of applications. This multifunctionality is something you will appreciate a lot if you decide to buy this inverter. It is also easy to transport and to simply set it to work. It does not have many buttons and it is generally known to have a good durability.
So in case you are looking for simple, relatively cheap, power sine wave inverter that still works good, you should definitely consider this product. It will leave you satisfied.

It can be portable, so you can also use it in different applications and while travelling. It weighs less than pounds which makes it relatively light. Besides silence and reliability the strongest point of this inverter is also durability. Because of that, it is certainly the kind of item that somebody who is buying long term wants to buy. What is more is that it does come with the manual for easier installation. It is a very cheap inverter, so it is good if you are looking for something in slightly lower price range and if you are ok with only few features. Despite the cheap price, it does not disappoint you and you will grow fond of it.
Next, think you plan to power which devices with the inverter you are buying. You will be able to find a label that indicates the wattage it requires to operate on each of your devices.
For instance, at the same time you need to use two 600 watt gadgets, you will need an inverter that is capable of a 1200 watt output.
However, at the same time, if you know that you would not ever be using these two gadgets anyway, you need to buy a 600-watt inverter.
Below here are some tips on how to use it safely
Be sure that the inverter is outside from the car that is powering, with the exhaust pointing away from the house. And at least 1feet away to keep down the risk of exhaust entering your home.
Plugging cords into the inverter or connecting the inverter to the battery can cause a spark.
Keep the inverter away from anything that is freeing flammable gas. Connect an inverter only to remote terminals or a car battery.
Never to your cigarette-lighter has an adapter or AC powered source of your vehicle. It can’t supply enough current to run the inverter, though the cigarette-lighter adapter is 12-volt.
Keep it as far as possible from the engine compartment of the car, once you have connected the inverter in a cool, dry space. It prevents the device from overheating. And it prevents any fumes from igniting should ignite the device spark.
Use only safety-approved extension cords for anything you’ll connect dry and undamaged that are rated for at least 1amps. Through a dry area route them where they cannot be pinched or crushed.
Particular chargers, especially for battery-operated portable devices that lack charger or transformer can be destroyed if plugged into the inverter. These include cordless razors, flashlights, and electric toothbrushes.
By using power inverter, not all cordless hand tools can recharge. So check the manual of the owner that came with the tool before trying to recharge the batteries. A few tools are also carrying a warning label that you should heed.

You install this style of microwave above your range, which will save you some counter space. These models have vent systems that take the place of the oven hood and lights to illuminate your cooktop.
Built-in models that you place among custom cabinets or paired with built-in, full-sized wall oven are the most high-end (aka expensive) types of microwaves. Some microwaves in this category are even designed specifically as drawers with a compartment you pull out for your food.
Microwave wattage equals power. In general, the higher the wattage, the faster and more evenly your food will cook. Most microwaves sit somewhere between 600-1,200 watts. Larger, more expensive microwaves tend to have a higher wattage, so this is a price and size consideration that can strongly influence microwave cooking performance.
Many microwaves share common functions. Here are some microwave cooking essentials: cook time, defrost, power level and timer. Each one requires your direct input, but they are usually very easy to set. Most microwaves have touch panel controls and a rotating carousel to spin your food for more even cooking.
Many microwaves come with preset cooking modes so you only have to press one button to automatically cook a dish. For example, many microwaves have a “popcorn” button that will cook your bag based on factory settings. This can be handy for common dishes you heat in the microwave, but you’ll have to figure out if the microwave’s default cook times work for your own food. Other common presets include: baked potato, pizza, beverage, frozen dinner and reheat.
Manufacturers are increasingly including features in microwaves that mimic what we see in full-size ovens, such as a broiler. This is a good addition for finishing off a dish or cooking something for which you’d prefer more direct heat.
A convection fan that’s built into the back of a microwave oven circulates the heat around the food to cook things more quickly and evenly. (Many new full-size ovens come with at least one convection fan.) However, microwaves with convection fans are generally more expensive than those without.
Inverter heating is another option available on some high-end models. If you want to heat something at a 50 percent power level, most microwaves actually switch between 100 percent power and 0 percent power to average in at 50 percent power. This doesn’t yield great results if you want to heat something on a lower heat and achieve an even result. So, some models now use inverter technology, which maintains a consistent 50 percent power. That way, you can poach salmon, make a fluffy omelet, etc.
RV Power Converter Troubleshooting
First of all, determine if the RV power converter is the component which has malfunctioned in the system. After connecting the RV power converter to the power supply, proceed to check if the voltage, at the point of entry, is in the range of 108-130 volts, as any reading within this range will be okay.
After ascertaining the above, you can then check the voltage at the point where the RV power converter connects to the 12-volt DC breaker box. For normal functioning, this should be within the range of 11-1volts. A failing RV power converter will show readings which are below this. After checking on these two points, and ruling out a problem there, you will then look at the individual components.
The RV Power Converter Fan
A small fan is usually in place to cool the components of the RV power converter as the whole electrical system is charging. A fan that is functioning normally will produce some sound. The operation of the fan is powered with the 110-volt AC line.
If at any time, the fan malfunctions, it is pretty easy to replace the fan, but it may be tricky finding a replacement. Make sure you have the details of the original fan, such as: the make, the amperage, and the voltage. Online sources may help you find the correct one.
You may also need to replace your RV power converter thermostat, if it is not supplying enough voltage to the cooling fan.
In some of the RV power converters, a resistor controls the voltage to the batteries and the 12-volt DC system. Some models have it riveted to the converter box, and its reading should be in the range of 3-1volts. This will be determined by the charge present in your battery. Make sure the batteries are being fully charged, as a low charge would give a reading out of this range.
To access the resistor, it may be necessary to disassemble the converter box. You need to exercise caution when you remove the circuit board, as this is a vulnerable component. The rivet has to be drilled out, and then replaced by the correct resistor.
You can use any 12-volt DC resistor, provided the values are the same. These type are mostly used in automotive applications. After you are done with replacing the resistor, see to it that your batteries are fully charged using the right voltage.
You may find yourself in a situation which makes it hard for you to get the necessary replacement for the damaged part of your RV power converter. Purchasing and installing a new RV power converter is not terribly expensive. One brand of replacement you can consider is the Progressive Dynamics Inteli-Power converter. You have the option of selecting from several models, depending on your needs.
RV Power Inverter
An RV power inverter will convert 12-volt DC battery power into 110-volt AC power that enables your electronic devices to work. There are basically two types of RV power inverters: the Pure Sine wave power inverters and the Modified Sine wave inverters. The Pure Sine wave inverters are more efficient and effective, but are more costly, while the Modified Sine wave inverters are more affordable, and they will power most of your commonly-used electric devices. Fancy and expensive devices will require you to use an RV power inverter of the Pure Sine wave type, and the outlets which are from Pure Sine wave inverters are usually protected by GFCI.
One great thing about the EU2000i is that you can buy the companion generator which would then double your power to 4000 watts. These are daisy-chained together. However, if you need more wattage, we would recommend upgrading to the EU3000i Handi as fewer components is always better as it minimizes your risk of problems.
If you are looking to go boondocking but need some power, this is likely the best portable generator as it is what you will see most in the RV community.
Ideal For: portable home emergency backup power, utilizing the benefits of propane to provide enough power to cover essential circuits in your home.
A huge advantage to propane-powered generators over gasoline-powered generators is that propane can be stored for an indefinite amount of time without the need for stabilizers. In an emergency, gasoline may not be readily available and pumps require electricity to work, so it can be convenient to have multiple propane tanks stored for an emergency.
We recommend that you buy an inverter twice the size of your total energy requirements so that you have extra capacity and do not run the risk of overloading your inverter.
Batteries are required to store energy from NEPA, Generator or a renewable energy source e.g solar panels. Batteries are an essential part of any power backup system and the performance and longevity of your inverter system will largely be dependent on the quality of the batteries you use.
The minimum required size of your battery bank will be determined by the voltage requirements of your inverter. A 12-volt inverter, for example, requires 1volts and will work if you connect it to a single 12v battery. A 24-volt inverter will require 2volts, which you can achieve by connecting two 1volt batteries in series.
The most common inverter battery capacities available in Nigeria are 12v 100AH and 200AH.
The minimum required battery bank size may or may not be enough to meet your needs. You can determine the correct sizing for your home by using the following formula.
Amp rating of battery x inverter voltage (assuming 80% efficiency ) load wattage.
Inverter Battery Brands
There are a lot of inverter battery brands available on the Nigerian market. The problem is that the majority of these batteries are relatively low-quality compared to those from dedicated inverter battery manufacturers. This is why most experts recommend investing in a battery from reputable manufacturers such as Mercury.
Warranties and Guarantees
A warranty simply means the manufacturer will be willing to provide maintenance and repair of certain components for a specific number of years or months if a malfunction occurs, while a guarantee stipulates a brand new replacement if faulty.
Quiet Enough for Camping
As someone who enjoys tent camping, I can assure you that a standard generator running in a campsite will earn you more than a few angry looks. But the models we are highlighting are so quiet that your neighbors are unlikely to even know it’s running.
This style of generator is great for RV camping as well. A couple of the models we will be highlighting have 30A outlets specifically for hooking up to your RV to run air conditioning systems, refrigerators, and other devices. Most of these units even have enough power to accommodate a TV and lights as well.
Home Backup Generators
The run-time at 25% load for the Honda is 8.hours. At the rated (1600W) load this drops to 3.hours. This is slightly less than the Champion, but a good bit ahead of the Wen.
Honda’s “Eco Throttle” system balances the engine speed to the required load. This allows the unit to be as fuel efficient as possible.
There are two big selling points for the Honda.
While Champion and Wen will require you send in a defective model for repairs (or send you the parts). With Honda you can most likely find a qualified technician nearby. This is a huge advantage when you’re relying on your generator for power in more remote areas.
Features & Performance
There is also an automatic shut-off for low oil situations.
One particularly nice feature is the fuel gauge which none of the other units in this comparison have. On the downside the Yamaha does not have a USB charging port for phones and tablets. These devices can obviously be charged using the 120V ports of which there are two.
Fuel Efficiency and Run-Time
Since inverter generators are able to regulate engine speed based on current power demands they can be up to 40% more fuel efficient than standard models.
An inverter generator (IG) can run at much lower speeds because the technology incorporated into the unit allows for constant frequency output without a corresponding engine RPM. This means that an IG will consume less fuel when power demands are low, and can ramp up to meet additional load requirements.
IG’s are generally designed from the beginning to be smaller and more portable. This has a direct impact on the amount of fuel it can store. But even with smaller fuel tanks, many IG’s have run-times of up to hours due to their highly efficient engines.
A more efficient engine also has the added benefit of reduced exhaust emissions and a smaller carbon footprint.
Winner: Standard Generators
Power Quality and Consistency In terms of the power produced there are significant differences between the two types.
Parallel or Tandem Operation
One particularly attractive feature of many inverter generators is that they can be used in parallel or combined to increase their power output.
This is a function that standard generators are unable to provide.
Generally all that is needed to accomplish parallel operation is a special cable that connects the two units. This can vary by unit, so be sure to read the details about the particular model you’re looking at to ensure it provides for this capability.
Other nice options include an hour meter to help keep track of oil changes and a voltage regulator to protect more sensitive electronics such as TVs, laptops, and smartphones. Keep in mind that most portables are designed for equipment like power tools and adding a regulator can increase costs and it’s one more thing to break. So if you don’t need it, just go without.
Starting and running power requirement of all electric appliances are different. An 1Watts CFL takes around 2Watts power to start and after few seconds it stabilizes to 1Watts. Some appliances like Refrigerator, Washing Machine etc take almost double power to start as compared to the normal running power. Hence before selecting an inverter you must calculate the starting power requirement also.
Difference between VA and Watts
The ratio of Power in Watts to Power in VA is termed as Power factor. Unfortunately manufacturers often don’t specify the power factor or efficiency in their products.
Let’s see an example. You are purchasing an inverter with 650 VA power ratings. This 650 VA indicates, it can supply 650 VA power under ideal situations( means efficiency of the inverter is 100%). If we take 80% as a typical efficiency figure, the said inverter can supply 80% of 650 = 520 Watts only. Now you can understand why inverter manufacturers only publish the VA rating on their products. If an inverter or UPS is coming without mentioning power factor, you must take a safe value of 0.(60%) as power factor while connecting appliances.
What is digital in inverters? First generation inverters were using power transistors as switching devices and transistorized circuitry for monitoring/controlling applications. That is an old story. Nowadays inverter technology has changed a lot. A complete transition from old square wave technology to Pure Sine wave technology with the help of advanced Digital Signal Processing (DSP) techniques. Micro controllers are extensively utilized for précised monitoring and controlling applications. Switching transistors are replaced with high efficient MOSFETs.
Batter- the vital part of inverter. Performance and life of an inverter is greatly depends upon battery. We can see several classifications of inverter batteries. Normally high power Lead Acid batteries are used to power inverters. Lead acid batteries are classified in to different types as per application, design, technology etc.
Maintenance Free batteries
Lead acid batteries require regular maintenance. You have to check the electrolyte level and require to be topped up on regular intervals. Moreover these batteries release poisonous gases during charging and discharging. If you don’t keep the batteries in a properly ventilated place, it can invite serious health problems. You have to keep the terminals of normal lead acid batteries corrosion free by applying petroleum jelly or grease regularly.
Maintenance free batteries are sealed lead acid batteries which do not require topping up or additional ventilation.
This is the most popular segment of inverter batteries-Tubular batteries have several advantages compared to flat plate batteries. More complex design increases the manufacture cost but the high electrical efficiency and extra long life make tubular batteries suitable for both domestic and industrial applications. A good maintained tubular battery can run unto years or more. Tubular batteries comparatively require less maintenance. Cost of tubular batteries can go up to double of a normal flat plate battery, however if you have a high efficiency inverter then go for a tubular battery, you will not regret. Almost all popular battery brands in India like Exide, Prestolite, Amaron etc have specially designed tubular batteries for inverters.
Batteries from Inverter manufacturers
We can see that almost all inverter manufacturers supplies battery along with inverter. I strongly suggest-don’t go for such batteries. This is a simple business technique, often they just market batteries on their brand name. As battery costs more than inverter, it is always better to go for a reputed and trusted battery brand. I have personal experience with Exide and Prestolite tubular batteries. Exide Invatubular batteries run flawlessly upto years.
Local made batteries
Efficiency of an inverter is proportional to the amount of power drawn. It can varies from 90% to 50% from full load to light load. Here the notable factor is that inverter efficiency is high on maximum load. Generally an inverter is in its most efficient capacity when being used at around 1/to 3/of it’s full rating.
Power Consumption of inverters
Inverters take mains power supply to charge the batteries. If the charging section of an inverter is not energy efficient, it will waste electricity even after the battery is fully charged. This will inflate your electricity bill. It is very difficult to check this aspect in shop before purchasing an inverter. However you can test the same at your home. Switch off all appliances except the mains supply to inverter, disconnect the battery and measure the power consumption for a specific period.
Battery backup duration
Solar Panel input: In typical Indian situations even eight hours of continuous commercial power supply availability can not be assured. Hence many people use the most reliable and alternate non conventional power source- Solar energy. Nowadays inverters facilitates the usage of Solar Panels also. Those inverters are embedded with solar charging circuits and regulators.
LCD Status Indicators: Modern inverters come with LCD status indicators to display various status like Battery charge level, Load, Input/Output voltages, Battery life etc.
Voltage stabilizer, High/Low voltage cutoff : Normal inverters don’t stabilize the mains supply, means the commercial supply is routed directly to the appliances without monitoring. Some inverters comes with in built voltage stabilizer, which protects your appliances from voltage fluctuations.
Earth Leakage Protection: Earth leakage protector is a safety device used to protect users from electric shock and appliances from damage. Modern inverters come with in built earth leakage protection circuits, which continuously monitor earth leakage and cut off the supply to safeguard the users.
After Sales Support
We can’t give a blanket suggestion in favor of a particular brand or model. All electronics equipment are prone to damage, hence after sales support is always paramount which varies from place to place. As inverters are static devices, go for a dealer or brand who offers on site warranty repair and maintenance.
So you have narrowed down your list of potential power inverters suppliers, done your due diligence and decided on one factory to manufacture your power inverters. But before you sign that contract, you would most probably need to negotiate quality, price and payment terms.
Protecting your IP
While most suppliers in China are trying to earn an honest living, there are also a large number of unscrupulous companies who are out to make a quick buck. And one of easiest ways to do this is by stealing your intellectual property. Most people think IP just refer to designs and trademarks. But it also includes sensitive buyer information such as export value, shipping destination, customer and end- user identity, and market value of goods shipped.
Do not share info without nondisclosure or other agreements in place.
At the same time, do not rely solely on NDAs and non-compete agreements. Attach bilingual MOUs to purchase orders. The MOUs must be initialed by a person in authority.
Distribute components to various suppliers instead of just one. Your payments, penalties, and ship dates should be contractually tied to QC reports.
