Description
Solar Off-Grid MPPT PCU consists of an MPPT Solar Charge Controller, Offline Inverter, and Grid Charger all in an integrated from. The OFF-Grid Solar PCU is designed to maximize to use of Solar Power. When the batteries are charged from Solar, the smart PCU disconnects Grid/Mains/DG and let the Inverter/Load run on solar. It Generates maximum form Solar, also as per the user preferences it has three modes:
- Smart Mode (PCU gives priority to solar, second priority to the grid and third priority to the batteries in smart mode). Recommended in semi -urban Area, where power cut is between 2-3 hours
- PCU Mode (PCU gives priority to solar, second priority to the batteries and third priority to the grid in PCU mode). Recommended in urban Area, where power cut is less than 2 hours.
- Hybrid Mode(In this mode CPU works well with solar as well as batteries. Grid Charging only takes place when solar power is not sufficient to charge the batteries). Recommended in rural area, where power cut is more than 3 hours.
