Description:

When the photovoltaic energy is sufficient, the energy is output to the load through the inverter after MPPT tracking, and the excess energy is input to battery packs for charging.
When the photovoltaic energy is insufficient, the solar energy and the battery packs supply power to the inverter at the same time or the mains bypass operation. When the battery energy recovers during bypass operation, it automatically switches back to the inverter output.

Basic system architecture

 

1.DC priority mode:
When the photovoltaic energy is sufficient, the energy is output to the load through the inverter after MPPT tracking, and the excess energy is input to battery packs for charging.
When the photovoltaic energy is insufficient, the solar energy and the battery packs supply power to the inverter at the same time or the mains bypass operation. When the battery energy recovers during bypass operation, it automatically switches back to the inverter output.

2.AC priority mode:
After this mode is enabled, as long as the mains input is normal, the system will switch to the mains bypass output, and then switch to the battery inverter power supply when the mains is abnormal.

3.Super energy-saving standby mode:
After the energy saving mode is enabled, the machine automatically enters the standby state, and the batteries are charged by solar energy. If the AC input and solar energy input are abnormal, the machine will automatically shut down; when the AC input or solar energy input returns to normal, the machine will automatically start and enter standby mode.

4.Intelligent output function:
The loads are divided into the important load which need priority to power supply and general load. The system automatically controls the power distribution according to the remaining energy, to ensure that priority supply to important loads. In the case of limited batteries and photovoltaic panels configuration, which can extend the backup power supply time of important loads as much as possible.
