1)Max. efficiency 97.0% 2)soft or variable frequency start option 3)Battery manage option 4)Support Grid and generator backup

1.Overview

SDB is intelligent all-in-one unit, which combined MPPT controller, inverter and battery DC-DC charger, and integration system controlled by core chip TI DSP.

The unstable DC power from PV panel through SUNFINE SDB to transform single 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. SDB 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.
