Who is the top 5 solar inverter manufacturer?

While your inverter decision will ultimately be based on your unique setup, a few factors should be considered when comparing your options.

OMMO contains other products and information you need, so please check it out.

Output power

The output power of your inverter provides a sense of its size. To avoid clipping, you&#;ll want the size of your inverter(s) to align with your solar panels&#; output. 

&#;Clipping&#; occurs when your solar panels produce more power than your inverters can handle at a given time. If your inverter&#;s power output rating is lower than your solar panels&#; output, your production will be &#;clipped&#; at the inverter&#;s output, and you&#;ll lose that extra power your panels could produce.

• For microinverters: The maximum output power should be about the size of your solar panels (typically 300-400+ Watts). 

• For string and optimized string inverters: The maximum output should be close to the size of your solar panel system (typically about 5-10 kilowatts (kW)). 

• If you have multiple string inverters: Make sure each inverter's output power roughly matches the total wattage of its string of solar panels. 

Efficiency

Not all the electricity generated from your solar panels makes it to your appliances. Solar panels capture direct current (DC) electricity, and inverters convert that to alternating current (AC) electricity for your home. Some thermal energy is lost in conversion, but an efficient inverter loses less energy. 

Efficiency ratings are expressed as a percentage (the higher the, the better). These days, most inverters are 96% to 99% efficient. 

Voltage performance

The minimum and maximum voltages (expressed in DC) provide a voltage level range at which your system can input solar energy from your panels to your inverter. The wider the range, the better your inverter can perform in more extreme conditions. You can calculate your inverter's voltage performance using the following calculation:

(maximum voltage &#; minimum voltage) / maximum voltage

Your voltage performance will generally range between 0.4 and 0.8, with higher numbers indicating better performance. If you have an optimized string inverter system, include the voltage range associated with the power optimizer. 

Nominal voltage is another metric for your inverter. It's pretty standardized for all home solar energy systems and represents the voltage level at which your inverter connects to your home's electric system (expressed in AC). Most inverters for home solar systems will connect at either 208 or 240 VAC.

Warranty

If you're noticing any unusual issues with your solar panel system, chances are it's the inverter. While solar panel systems are highly reliable, inverters are the most likely component to fail. So, you want to ensure that your inverter has a comprehensive warranty if anything goes wrong. 

MLPEs like microinverters or power optimizers often come with a 25-year warranty, like the solar panels they live behind. On the other hand, most string inverters come with a warranty of around 10 years. It's also important to consider other warranty factors like labor coverage and company bankability (i.e., how likely they will be around to uphold your warranty).

A solar inverter is a crucial device that plays a pivotal role in solar energy systems by converting DC power generated from solar panels into usable AC power for the load. It serves as one of the core components and is considered the most intricate part of solar energy storage. Hence, selecting the right solar inverter holds significant importance.

Keeping this in mind, we have compiled a list of 15 global solar inverter manufacturers in . These companies offer highly competitive products, providing a range of options to choose from.
