1.Overview
SUNFINE SMB series is all-in-one unit in off grid solar power system which with battery bank. It is system integrating MPPT controller, Inverter, and Battery DC-DC charger function, also has battery manage function for option. SMB supports Grid or AC generator backup. The charger mode is 3 steps: CC, CV and FC automatically.
The excess power from PV panels will charger to battery, and when solar power is lacking, battery will make up the rest or serve as complete power source. Switching time between PV/Grid/Battery for Standard configuration unit is less than 5ms. Soft or variable frequency starting way options is for different type loads.
Our standard sequence of power supply of SMB is solar, grid and battery.
