In a typical PV system, the inverter/charger converts DC power from the batteries into AC that can power standard appliances and other energy loads, and converts AC into DC energy that can charge deep cycle batteries. This two-way exchange of energy is crucial for efficiently storing and using energy harvested by PV systems.

Hybrid inverter/chargers also allow multiple AC sources, such as a generator or the grid, to charge batteries. Whether you live off-grid and have cloudy days, or have utility power and the grid goes down, the inverter/charger can provide reliable and ready power.
