中文SPW-B 48V/51.2V 100Ah Power Wall Lithium Energy Storage Battery
Automatic voltage recognition
LCD display
MPPT tracking charging
The SSM controller is suitable for automatic control of charging and discharging processes in solar off grid systems (independent systems). The charging mode of the controller is divided into MPPT and DC-DC, and the discharge process of the battery is optimized to extend the battery's life and improve system performance. Its comprehensive electronic protection function can prevent users from damaging the controller due to installation errors and system failures.
1. Automatic voltage recognition
2. Lightning protection
3. Adopting large screen LCD display
4. Over charge, overdis charge, over load, short circuit, and battery anti reverse protection
5. Adopting MPPT tracking mode to effectively improve charging efficiency
