A general rule of thumb is that you can put up to twice as many panels on an inverter as the inverter can handle in watts. The inverter converts the direct current (DC) generated by solar panels into alternating current (AC), which can then be used to power homes or businesses. How many panels can a 5kW inverter handle? To determine the overall wattage of the system, we divide 5,000 by the 400. . A solar array can be up to 130% of the inverter capacity. With a 5kw inverter, you can have up to 6.
