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.
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.
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.
For example, a 5 kW solar array typically requires a 5 kW inverter. However, factors like derating, future expansion plans, and the array-to-inverter ratio influence the optimal inverter size. Most installations slightly oversize the inverter, with a ratio between 1.1-1.25 times the array capacity, to account for these considerations.
Using the example of ten 300-watt panels, your total power output is 3,000 watts. Solar inverters have an efficiency curve, which shows how efficiently they convert DC power from the solar panels into AC power for your home. In general, look for an inverter with an efficiency rating above 95%.
