Before you hire: 6-point checklist
- Registered electrician & CoC: the DB-board tie-in must be done by a registered electrician who issues a valid Certificate of Compliance (CoC).
- Correct sizing: the system should match your actual load in kW and your desired backup hours in kWh — not a one-size-fits-all package.
- Battery chemistry & warranty: ask whether it's LiFePO4 or lead-acid, and check the cycle-life and warranty — lithium costs more upfront but lasts far longer.
- Inverter brand support: choose a brand with local support and readily available spares, not the cheapest unknown import.
- Written quote after a site assessment: insist on an on-site assessment and a written quote, never a phone estimate.
- Proof of past installs: ask for recent installations you can see or reviews you can verify.

Frequently asked questions
How much does an inverter and battery cost in Johannesburg?
A basic-to-whole-home inverter and battery backup system in Johannesburg typically costs R25 000 to R120 000 installed in 2026, depending on inverter size (kW), battery capacity (kWh) and how complex the DB-board tie-in is. A full hybrid solar system with panels runs R90 000 to R280 000. Always get a site assessment quote rather than a phone estimate.
Do I need an electrician or a Certificate of Compliance (CoC) in Johannesburg?
Yes. Any system wired into your home's DB board must be installed by a registered electrician and issued with a Certificate of Compliance (CoC). This protects you, your insurance and utility workers, and ensures a generator or inverter can never back-feed the grid. Never accept a system tied into your wiring without a CoC.
Inverter vs generator vs solar — which is best in Johannesburg?
An inverter and battery gives silent, automatic backup for essentials like lights, Wi-Fi and the fridge. A generator is cheaper upfront and runs indefinitely on fuel but is noisy. A hybrid solar system costs the most but also cuts your electricity bill and recharges from the sun through high-stage load-shedding. See our inverter vs generator vs solar guide for the full comparison.
How long does a backup power installation take in Johannesburg?
A straightforward inverter-and-battery installation is usually completed in a day, sometimes two. A full solar system with roof-mounted panels typically takes two to three days. Lead times before the work starts depend on installer availability and stock of your chosen inverter and battery brand, so book a site assessment early.
