The inverter"s capacity should match the DC rating of your solar panels as closely as possible. For instance, if you have a 5 kW solar array, you would typically need a 5 kW inverter.
The size of the solar inverter you need is directly related to the output of your solar panel array. The inverter''s capacity should ideally match the DC rating of your solar panels in kilowatts (kW).
Calculate the right inverter size for your solar panel system.
But before you start soaking up the sun, you''ll need the right inverter to match your system. This guide breaks down what size solar inverter you actually need—so your setup runs
