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.

It supports both off-grid and grid-connected modes, suitable for off-grid solar systems, grid-connected solar systems, and mixed grid systems, unaffected by power outages and with intelligent switching. Equipped with an independent MPPT, it easily handles complex installation environments and fully utilizes solar energy. It supports rapid charging and discharging for faster energy replenishment. The modular design supports multiple units in parallel, allowing for flexible capacity expansion. It provides continuous and stable green power solutions for off-grid residential, industrial, commercial, and communication base station scenarios.
