Inverters : Which one is the best for you – Hybrid Systems

Solar systems seems complex with all the choices you must make to get to the right system for you. A solar system is defined by the type of inverter it use to produce electricity. There are a number of types, brands and philosophies available in the market. Which one is the best for your requirements?

We will try to simplify the system design by discussing the different inverters available to you.

Hybrid Systems

Hybrid systems use Solar power to charge Batteries and supply power to the building. Eskom power is used as backup power supply.

Hybrid systems consists of the following components:

  1. Solar modules that collect sunlight and convert it into DC power
  2. Batteries
  3. Charge controller that charge the batteries
  4. Inverter that converts the battery DC power into AC power

(The charge controller and inverter may be combines in one unit)

This is how it works:

The charge controller charges the batteries from the solar modules

The inverter convert the battery power to AC power for the building on demand

If the batteries charge is low, it will switch over to Eskom power
If the batteries charge is low, it might use Eskom power to charge the batteries

Hybrid Systems are ideal for the following scenarios:

  • Ensure a steady power supply, even during power outage
  • Extra solar power generated during the day is stored in batteries for consumption at night

The Hybrid system needs to be sized correctly to handle the maximum load. Multiple Hybrid Inverters can be interconnected to increase the load capacity of the system
