Product Description
MPPT Solar Charge Controller
Inverter
AC Input / AC Output
Battery
Solar Off-Grid System is an independent power generation system that operates without relying on the public utility grid.
Solar panels generate electricity, which is regulated by a controller, stored in batteries, and then converted into AC power by an inverter for use by electrical loads.
