Battery only add-ons from R25,000. Full battery plus inverter backup installations for Sandton homes typically land between R40,000 and R90,000 depending on battery size and inverter choice.
If you already have a hybrid inverter installed, adding a battery module is a straightforward job. These prices are for the battery hardware only, inclusive of BMS communication cabling and installation to an existing compatible inverter.
| Battery Module | Usable Capacity | Installed Price (ZAR) |
|---|---|---|
| Pylontech US3000C | 3.5kWh | R25,000 |
| Hubble AM-2 | 5.0kWh | R30,000 |
| Freedom Won LiTE | 5.0kWh | R40,000 |
All three batteries use LiFePO4 chemistry, all three carry approximately 10 year or 6,000 cycle warranties, and all three are supported locally with parts and technical backup. Freedom Won is the premium local option and prices reflect that. Pylontech is the value option with the longest South African track record.
For a Sandton household starting from zero, a proper backup installation requires more than just the battery. Here is the full line item breakdown.
| Component | Cost Range (ZAR) |
|---|---|
| Battery module (Pylontech, Hubble or Freedom Won) | R25,000 - R40,000 |
| Hybrid inverter (Deye or Sunsynk 5kW) | R15,000 - R25,000 |
| Wiring, breakers, isolators, DB modifications | R3,000 - R6,000 |
| Installation labour | R5,000 - R10,000 |
| Electrical COC on completion | R2,000 - R3,000 |
| Total installed cost | R40,000 - R90,000 |
A large share of the Sandton clients we speak to want load shedding relief now, but are not ready to commit to a full solar installation at R120,000 or more. The answer is to start with a battery and hybrid inverter setup for backup only, then add solar panels 12 to 18 months later once the household has built confidence in the system and cash flow allows.
The key to making this work is inverter choice. A hybrid inverter such as the Deye 5kW or Sunsynk 5kW has three inputs built in from day one. Grid input, battery input and solar input. When you install only the battery on day one, the solar input simply sits idle. On the day you decide to add panels, the wiring is a straightforward connection to that dormant input. No inverter replacement, no rework of the DB board.
This staged approach also helps with sizing. Once you have lived with the battery for a year, you will know exactly which circuits you actually use during outages and which loads drain the battery fastest. That real household data leads to a smarter panel sizing decision than any pre-installation load calculation would produce.
The alternative is installing a cheaper off grid inverter for backup only. That saves money upfront but forces a full inverter replacement when you add panels later, which cancels out the initial saving. For any Sandton home planning to eventually add solar, the hybrid inverter approach is the more sensible route.
Battery backup is a competitive space in Sandton and cheap quotes usually cut corners in predictable places. Here are the pitfalls we see most often when we inherit failed installations.
Yes, provided you install a hybrid inverter from day one. A Deye or Sunsynk 5kW hybrid inverter has the solar input hardware built in, so when you add panels 12 to 18 months later it is a straight connection to the existing inverter. No inverter replacement is needed. This is the most common path in Sandton right now.
A 5kWh battery covers roughly 4 to 5 hours of typical Sandton household backup running fridge, router, lights, TV and security. If you include a pool pump or geyser the runtime drops sharply. We size the battery based on your specific priority circuits, not on a generic wattage estimate.
Pylontech has the longer track record in South Africa and pairs cleanly with almost every hybrid inverter on the market. Hubble is locally supported with strong warranty backup and slightly higher usable capacity per module. Both are LiFePO4 chemistry, both come with roughly 10 year warranties. For most Sandton homes either brand is a sound choice.
Modern LiFePO4 batteries are rated for around 6,000 cycles at 80% depth of discharge, which translates to roughly 10 years of daily use. Warranties from Pylontech, Hubble and Freedom Won are typically 10 years or 6,000 cycles, whichever comes first.
No. A battery only backup that does not export to the grid does not require SSEG registration. City Power SSEG is only mandatory once you add solar panels and the system can push power back to the municipal network. A COC is still required for any electrical work.
