System working mode description
PV mode
1. In addition to the user's load, the PV energy is stored in the battery.
2. When the power of the solar energy is not enough to meet the user's load, the amount of electricity stored in the battery will be added to the load.
3. When the battery is low enough, the system will switch to the power supply when the power is low.If the battery is in a serious shortage, the system switches to the market to power the load, and the battery will be started to charge.
Electric supply mode
1. AC (municipal power) is fed into the user's load, the battery is charged only by PV energy.
2. When the battery is severely depleted, AC (municipal power) will start to recharge the battery in addition to the user's load, but it will not be full of batteries at this time.
3. When AC (municipal power) is cut off or abnormal, the system switches to the battery to power the load
