6 FAQs about [67 How big an inverter should I use for photovoltaic power generation]

How do I choose the right solar inverter size?

When it comes to solar inverter sizing, installers will consider three primary factors: the size of your solar array, geography, and site-specific conditions. The size of your solar array is the most important factor in determining the appropriate size for your solar inverter.

What wattage should a solar inverter be?

Installers typically follow one of three common solar inverter sizing ratios: For our example 7 KW system, this translates to inverter sizes between 8,750 watts and 9,450 watts. While the above wattage rules apply to a majority of installations, also consider the following factors before deciding the sizing ratio.

Which solar inverter should I Choose?

The choice between a single-phase or three-phase inverter will depend on the size of your solar array and your electrical service. Generally, single-phase inverters are suitable for smaller solar installations (up to around 10 kW), while three-phase inverters are necessary for larger systems.

What size inverter do I Need?

Inverters come in different sizes starting from as little as 125 watts. The typical inverter sizes used for residential and commercial applications are between 1 and 10kW with 3 and 5kW sizes being the most common. With such an array of options, how do you find the right size for you? An inverter works best when close to its capacity.
