Inverters : Which one is the best for you – Off Grid 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.

Off Grid Systems

Off Grid systems are not connected to the Eskom grid, but use solar power as the primary electricity source

Off Grid 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 combined 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 not generate any electricity
If the batteries charge is low, it might start a generator to supply power to the house, and charge the batteries

Off-Grid systems are ideal for the following scenarios:

  • New building where the cost of connecting to power Eskom is too high
  • You wish to be completely independent of Eskom
  • The monthly fixed connection cost is exuberant relative to the consumption cost

Off Grid systems can use a generator as backup
