The unstable DC power from PV panel through SUNFINE SMB3 to transform three phase pure sine wave AC power to loads, excess power charge to battery automatically; And when solar power is lacking, battery will make up the rest or serve as complete power source. SMB3 supports Grid or AC generator backup.
Switching time between PV/Grid/Battery for Standard configuration unit is less than 5ms. The charger mode is 3 steps: CC, CV and FC automatically.
