Zieus Solutions Green UPS


Zieus, Solar Hybrid PCU is an integrated system consisting of a solar charge controller, inverter and a Grid charger. It provides the facility to charge the battery bank through either a Solar or Grid/DG set. The PCU continuously monitors the state of battery voltage, solar power output and the load. Due to constant usage of power, if the battery voltage goes below a set level, the PCU will automatically transfer the load to the Grid/DG power and also charge simultaneously. Once the batteries are charged to the preset level, the Zieus Solar Power Conditioning unit cuts off the Grid/DG Power from the system and restores it to feeding the loads from the battery bank while also returning to charging the battery from the available solar power. The PCU always gives preference to the solar power and will use Grid/DG power only when the solar power / battery charger is unable to meet the load requirement.

  • Load sharing between solar and Grid.
  • 100 % Utilization of solar power using Power sharing MPPT Converter and solar PCU.
  • Industrial Grade IGBT inverter with complete Galvanic Isolation (Single phase output and three phase output -Three phase single Delta Star Transformer)
  • High Efficiency Temperature compensated flat cum boost charger for extended battery life.
  • Parallel operation for Solar and Grid.
  • Solar PCU module utilizes the entire power available from solar and in the event of short-fall in power availability from solar the mains power is drawn to compensate the deficit of power.
  • Power sharing in PCU for catering to the load can be configured as per our requirement. Example Solar primary source and secondary for grid third for Battery.
