1. Solar modules: convert light energy into direct current energy, charge the battery through the integrated machine, or directly invert into ac power to power the load.
2. Mains or generator: Connect to the AC input terminal to power the load and charge the battery.
If there is no power supply or generator, the system can run normally, and the load power is provided by batteries and photovoltaic modules.
3. Energy storage battery: The role of the energy storage battery is to ensure the normal power consumption of the system load when solar energy is insufficient and there is no electricity supply.
4. Household load: it can be connected to various household and office loads, including refrigerators, lamps, TV sets, fans, air conditioners, and other AC loads.
5. Inverter: energy conversion device of the whole system.
The specific system cable connection mode depends on actual application scenarios.

3.3.2 Charging mode
1. Photovoltaic priority: PV priority charging, only when the PV fails to start utility charging. Make full use of solar power generation during the day and switch to utility charging at night, which can maintain battery power and is used in areas where the grid is relatively stable and electricity prices are more expensive.
2. Mains priority: Manpower charges the battery first, and PV charging is activated only when utility power is not effective.
3. Hybrid charging: PV and utility power are mixed, with priority PV MPPT charging, and utility power replenishment when PV energy is insufficient. When the PV energy is sufficient, the utility power stops charging. This way of charging is the fastest, suitable for areas with the unstable power grid, and can provide sufficient backup power supply at any time.
4. Photovoltaic charging only (Only Solar): photovoltaic charging only, without starting utility charging. This way is the most energy-saving way, battery power are from solar energy, usually used in areas with good lighting conditions.
1. PV priority mode: PV and battery supply power to the load, diversified charging mode, and output mode can be selected. When the PV priority mode is selected, it can maximize the use of green solar energy and realize energy saving and emission reduction. Switch to the utility power supply when PV is not effective. This mode maximizes the use of solar energy, while maintaining battery power, and is suitable for areas with relatively stable power grids.
2. The utility priority mode: switch to an inverter power supply only when utility power is invalid, equivalent to backup UPS, used in areas with an unstable power grid.
3. Inverter priority mode: Switch to utility power only when the battery is under-voltage. This mode makes maximum use of DC power and is used in areas with stable power grids.
