A complete system consists of the following components:
PV Modules: Converts light energy into DC energy, which can be used to charge the battery via an inverter or directly inverted into AC power to supply the load.
Grid: Connected to the mains AC input, supplying power to loads while charging batteries. The system can operate off-grid when batteries and PV modules power the loads.
Battery: The role of the battery is to ensure the normal power supply of the system loads in case of insufficient photovoltaic and no utility power.
Home Load: Connects to a variety of home and office loads including refrigerators, lamps, TVs, fans, air conditioners and other AC loads. Generator/Smart Load/Micro-Inverter Input: When connected to an AC generator, supplies power to loads and charges batteries simultaneously.Without generator connection, this interface can be configured as a Smart Load output to power loads. When connected to micro-inverters, it supplies power to loads and charges batteries concurrently.
Inverter: It is the energy conversion device of the whole system.
