Solar Power Conditioning Unit, For Domestic, Voltage : 12.5kva 180v

Solar Power OperationThere is DC high cutoff (battery fully charged) and DC Low regain (Buffer backup voltage) points in Solar PCU. Once Solar PCU is with PWM/MPPT Charge controller  PWM/MPPT CC), will Charge batteries simultaneously along with Grid Charger. At this time load will be on grid. Once battery voltage reaches grid charger cut off preset voltage then grid charger stops charging. Now PWM/MPPT CC will charge batteries through Solar power. Load will be on grid. (Preset value as per customer requirement). When battery voltage reaches DC high cutoff voltage (Battery is fully charged). Then Solar PCU disconnects grid supply and Load is transferred to Inverter in 4ms. Now Solar gives power to inverter and for battery charging. Solar PCU will work through solar until solar is healthy. When solar power not sufficient PCU will take deficit power from battery. When battery voltage reaches DC Low regain (preset value as per customer requirement) (Buffer backup voltage) Solar PCU will shift load from Inverter to grid. Buffer backup is for emergency use in case of grid power failure. Now grid charger will charge battery up to buffer backup level for emergency and load will be on grid. Once Solar power is available then PWM/MPPT CC will charge the Batteries and the process continues. Solar PCU will not deep  ischarge the Batteries. On PCU Operation Battery Discharge level is customer adjustable. While PCU DC Low Regain Condition ,If Grid supply is not available then battery will give power to load. If the Battery is fully discharged and tripped. Solar PCU will automatically starts its Operation  Once Solar/ Grid available.
Sleep Mode

• Dusk down Operation
• (Optional for Evening/Night Load Condition)

Salient Features

• Solar PCU Continuously Monitors Output
• If Load is Less than 30w then Solar PCU will go to Sleep Mode
• Once Load is above 30W it will Initialize and Starts its Operation
• Solar PCU starts giving output where load runs only in the Evening / Night (When Solar is not available)
• Once solar power is available it stops giving output to the load. Thus No no load discharge and
• saves generated solar energy to its fullest.
