Done by an electrician
Backup power and solar from a qualified electrician
An inverter connects to your DB board and your home’s wiring, so the installation should be done by an electrician who looks at the whole system, not just the box on the wall. Before we recommend anything, we list the appliances you want to keep running and for how long. That decides the size of the inverter and batteries, and whether solar panels make sense for you.
- Inverter and battery backup for load shedding
- Solar panels to charge the batteries and cut daytime usage
- Essential circuits split at the DB board
- Batteries or panels added to an existing system
- Inverter systems that trip or won’t switch over
System sizes
Typical backup and solar systems
Every home is different, so treat these as starting points. We confirm the right size after looking at what you want to run.
Battery backup
A 5 kW inverter with a 5 kWh battery. Ideal for load shedding backup, and can be expanded into a solar system later.
Solar starter
A 5 kW inverter, 5 kWh battery and about 4.5 kW of solar panels, for an average home that wants to save on electricity and keep backup power.
Complete solar
An 8 kW inverter, 10 kWh of batteries and about 7.5 kW of panels, able to take an average home almost entirely off the grid during the day.
Large home or office
A 16 kW inverter, 20 kWh of batteries and about 14 kW of panels, for big homes, offices and off-grid setups.

Solar and backup FAQs
Can’t see your question? Call 012 383 2011 and ask the electrician directly.
What size inverter do I need?
It depends on what you want to run and for how long. We list your essential appliances, then size the inverter and batteries to match.
Will a backup system run my geyser and stove?
Usually not on a typical home backup system. Geysers, stoves and ovens draw a lot of power, so we normally keep them off the inverter and put lights, plugs, Wi-Fi and the TV on it.
Can I add solar panels or batteries later?
Often, yes, depending on the inverter you choose. Tell us if you plan to expand and we size the system with that in mind.
Why does my DB board trip since the inverter was installed?
It can point to a wiring or earthing problem in the changeover, or an overloaded inverter. We test the installation to find the cause.
Do you install backup power in Centurion?
Yes. We install inverters, batteries and solar panels across Pretoria and Centurion.
