Solar PV OFF-Grid systems

The Solar PV off Grid systems are supported for installation for Domestic and Commercial areas with electricity shortages that uses diesel generators for backup.

The Solar PCU (Power Condition Unit) is a bi-directional inverter system. The PCU Operates in parallel with the grid utility. Solar Photovoltaic modules Convert Solar Energy into Electrical Energy as DC Power. This DC Power is used to charge the batteries through a charger controller and a stand-alone power source is produced through the inverter and used for the Utility Load.

Depending on the solar irradiance/weather condition and the load connected, the solar PCU will automatically select between the following modes Solar Mode/UPS Mode/Grid Mode.

Mode of Operations

  • Solar – Battery – Grid (SBG) (Default Setting)
    In this mode – once solar power very low the load is transferred to the battery. If battery discharges to a present level, the load is transferred to the grid.
  • 2. Solar – Grid – Battery (SGB)
    In this mode – Once solar power is low the load the load is transferred to the grid. If grid fails the load is transferred to the battery.
