Inverter and Battery Backup Systems
An inverter and battery keeps your lights, Wi-Fi, fridge and gate running when the power goes out. Our backup kit starts at R43 600 installed, and every hybrid inverter we fit can take solar panels later.

How long will a battery last?
Rough guide, using about 90% of the battery's capacity. Real hours depend on what is switched on.
| Battery | Essentials (about 1kW) | Busier house (about 2kW) |
|---|---|---|
| 5.12 kWh | about 5 hours | about 2.3 hours |
| 10.24 kWh | about 9 hours | about 4.6 hours |
| 15.36 kWh | about 14 hours | about 6.9 hours |
| 20.48 kWh | about 18 hours | about 9.2 hours |
Inverter, battery and solar panel packages
Adding panels means the sun charges the battery and runs the house during the day, so you save on your bill as well as riding out outages.

Inverter and battery: common questions
How much does an inverter and battery cost?
Our backup-only inverter and battery kit and our full hybrid systems are listed on this page with live installed prices.
How long will an inverter and battery last during an outage?
Divide the battery size by what you run. A 10kWh battery running about 1kW of lights, fridge, Wi-Fi and TV lasts roughly 9 hours; run more and it lasts less.
Should I get panels or just an inverter and battery?
Backup-only charges the battery from the grid, so it only helps during outages. Adding panels also cuts your monthly bill because the sun runs the house during the day.
Can I add solar panels to my inverter later?
Yes, our hybrid inverters accept panels, so you can start with backup and add panels when you are ready.
Do I need to register an inverter and battery?
If it connects to the grid, yes. In Tshwane that is the SSEG process; Eskom-supplied homes register with Eskom.
