The best load shedding solution for most South African homes is a hybrid inverter paired with lithium batteries — it covers you during Eskom outages, scales up to solar later, and pays for itself within 5–7 years. But the right choice depends on your budget, how much power you need, and whether you want short-term relief or long-term energy independence.
| Question | Answer |
|---|---|
| Cheapest solution? | Portable UPS (R2,500–R6,000) for Wi-Fi and lights, 2–4 hours |
| Best long-term solution? | Hybrid solar inverter system (R85,000–R180,000 installed) |
| Can I run my whole house on battery? | Yes — 5kW inverter + 10kWh battery handles most 3-bed homes for 6–10 hours |
| Is solar worth it without load shedding? | Absolutely — Eskom tariffs rose 12.7% in April 2025 alone |
UPS Systems: Quick and Affordable
If your budget is tight and you just need Wi-Fi and lights, a UPS is where to start. A typical 1,000VA UPS runs a router, laptop, and LED light for 3–4 hours. Entry-level units like the Mecer 1,000VA start around R2,500. Mid-range options with lithium batteries cost R5,000–R8,000.
Inverter-Battery Systems: The Sweet Spot
A hybrid inverter connects to your home's DB board, automatically switching to battery when Eskom drops. Popular brands: Sunsynk and Deye (R12,500–R20,000 for the unit). Battery: 5.12kWh lithium costs R18,000–R28,000. Most homes need 10kWh for comfortable backup.
Total installed: R65,000–R95,000 for a 5kW inverter + 10kWh battery system.
Solar: The Long-Term Investment
Adding solar panels transforms backup into energy generation. A full solar and backup power system (5kW inverter, 10kWh battery, 8–12 panels) costs R120,000–R180,000 installed. Payback period: 5–7 years at current Eskom tariffs.

Frequently Asked Questions
Will load shedding come back in 2026?
Eskom has maintained stability since March 2024, but experts warn ageing infrastructure means it could return. Regardless, rising tariffs make backup power a smart financial investment.
Can I add solar panels to an existing inverter?
Yes, if you have a hybrid inverter (most Sunsynk and Deye units are). Get a free quote for an upgrade assessment.
How long do lithium batteries last?
Quality LiFePO4 batteries are rated for 6,000+ cycles — roughly 10–15 years of daily use with 10-year warranties.
Is financing available?
Yes. Nedbank, FNB, and Standard Bank all offer solar financing with 3–7 year terms. Monthly repayments are often less than generator fuel costs.
