Features
  • MPPT charge controller maximizes the extraction of solar energy while offering better scalability (adding more/higher capacity solar panels) in future
  • Efficient battery charging and reduced cycling prolongs battery life
  • 2 modes of Operation:
    • Auto mode: Prioritizes usage of solar power, minimizes consumption of grid power to charge the battery and power the loads
    • Manual mode: Over-rides the inverter input and allows for running of heavy loads (e.g. mixer grinder) if sufficient solar power is available
Controller Display LCD Panel
Controller - Monitoring Indicators Battery state, Solar state, Solar units generated, Mains supply availability, System state
Controller Dimensions 143mm * 95mm * 74mm
