4 Working mode
D series single phase inverter transformer based unit has three working modes:
DC priority, AC priority， ECO mode
4.1 DC Priority (Must be connected with batteries)
The inverter converts DC input current from either the PV panels or battery bank into AC current to supply the load. When battery voltage is low, the inverter will automatically switch to the main input power (gr/generator) to supply to the load. The system automatically switches back to DC after the batteries are charged again.
4.1.1 PV with battery bank (when PV is sufficient)
4.1.2 Battery only (when PV is not available, but battery power is sufficient)
4.1.3 AC only (when PV is not available, and battery power is insufficient)
4.2 AC Priority (must be connected with batteries)
While the AC input is stable, the inverter works in bypass mode to supply power to the load and charge the battery pack at the same time. When the AC input is too high / too low / serious distortion / abnormal frequency / fault, the system will automatically switch to the battery inverter to supply power to the load. Once the AC input has been stabilized, the system will switch back to bypass mode to supply power to the load automatically
4.2.1 PV is sufficient, AC power is available
4.2.2 PV is sufficient, but AC power is not available
4.2.3 AC power is available but PV is not available
4.2.4 Both AC power and PV are not available
