Hybrid systems

Hybrid systems

Hybrid systems are the standard Solar systems which uses Solar to charge Batteries and supply power to the building, with Eskom as tertiary power supply.

This solution is ideal for the following scenarios:

  • Electricity savings in conjunction with battery back-up to ensure a steady power supply, even during power outage

Hybrid systems consists of the following components:

  • Solar modules that collect sunlight and converts it to DC power
  • Inverter (with built-in charge controller and regulator) which:
    • receives DC power from Solar modules
    • receives AC power from Eskom
    • charges batteries with either Solar power or Eskom power (based on programming)
    • discharges batteries and converts it into AC power for supply to the building
  • Deep cycle batteries which are managed by the inverter to be correctly charged by Solar or Eskom & discharged to supply power to the building

The Hybrid system is connected to specific circuits as wired in the DB, e.g. Lights, dedicated plug points, etc. All power supply (load) to these connected circuits flows through the Hybrid inverter, irrespective if the power is supplied by Solar, Batteries or Eskom.

The Hybrid inverter needs to be sized correctly to accommodate the required load.

Hybrid systems are suitable for small to medium domestic, and very small commercial applications.

Hybrid inverters are available in different sizes. Multiple Hybrid Inverters can be interconnected to increase the load capacity of the system.
