Flexibile work mode

Strategy: The PV generator prioritizes meeting the demands of loads, and any excess PV power will be stored for later use.
Purpose: Reduce the electricity bill by minimizing energy consumption from the grid.

Strategy: when the power drawn from the mains falls outside the peak/low range, the battery will start to discharge/charge.
Purpose: Avoid additional alarms caused by extremely high demand and make good use of the power capacity contracted with DS.

 

Strategy: Preset a schedule for charging and discharging the system with a selectable time range and power rating.
Purpose: Make good use of electricity price movements to minimize the unit cost of electricity.

Strategy: PV generation and grid meet battery charging requirements; batteries are discharged only after grid failure.
Purpose: Provide longer back-up time and reliable power source
