A solar inverter is an important part of a solar power system. It converts all of the DC power produced by the solar panels to AC power. More than that, the inverter functions as the controller of a solar power system, providing base fault prevention and performance statistics. Inverters are also crucial to a solar system''s efficiency [12].

At the same time, the current has only one direction, either the photovoltaic current goes to the grid, or the grid current goes to the load. Therefore, there is no situation in which photovoltaic power is fed into the grid at the same time, and the load takes power from the grid. Q: Why is photovoltaic power generation given priority?

The key specification is ensuring the inverter amperage rating exceeds the intended charging current. For a 100W solar panel charging a 12V battery bank, the load would equal nearly 12 amps (100W / 120V = 0.8A; 0.8A*12V = 9.6A). Thus a 12A+ rated inverter could support the simultaneous usage safely.
