Residential Solar & Battery Backup — South Africa

The blackouts stopped.
The bills didn't.

Load shedding is over. Electricity went up 8.76% in April, with municipalities adding around 9% from July — and another hike already projected for next year. OffGrid Nation designs and installs solar and battery systems sized to what your home actually uses, so you stop renting your power and start owning it.

What you're on track to pay RISING

Your electricity bill right now:

In 5 years

R2 308

In 10 years

R3 551

Same house, same usage — just Eskom's own increases compounded at about 9% a year. A solar system is the one part of that bill you can fix.

Why bills keep climbing — Eskom's own numbers

R30.3bn

Eskom net profit after tax for the year ended 31 March 2026 — more than double the R14bn the year before.

−6.2%

Electricity actually sold over that same year: down from 189.7 TWh to 178 TWh.

Higher tariffs

Twice the profit on less power sold happens one way only: everyone still on the grid pays more per unit.

Those falling volumes are households leaving the grid — every one of them stopped paying the increase. Source: Eskom annual results, financial year ended 31 March 2026.

Packages

Two ways to do this.

Not sure what you need? Take one of the three ready-made packages — they cover most homes. Already know exactly what you want? Build it yourself, brand by brand.

Keep The Lights On

For a smaller home that just wants the power to stay on when the grid goes off.

  • Lights through the whole house
  • TV, WiFi and phone chargers
  • Fridge and deep freeze
  • Plug points in the main rooms
  • Geyser, stove and pool pump

5kW hybrid inverter · 6 × 565W panels (3.4kWp) · 5.12kWh battery

The Family Home

The one most households end up on. Covers normal daily living and takes a real bite out of the bill.

  • Everything in the smaller package
  • Washing machine and dishwasher
  • Microwave, kettle and air fryer
  • Home office and aircon in one room
  • Geyser and stove at the same time

8kW hybrid inverter · 12 × 565W panels (6.8kWp) · 10.24kWh battery

The Whole House

For a bigger property that wants to run more or less everything, most of the time, off its own roof.

  • Everything in the family package
  • Geyser on a timer
  • Pool pump
  • Multiple aircons
  • Runs through the night on battery

12kW hybrid inverter · 18 × 565W panels (10.2kWp) · 15.36kWh battery

Equipment

Panels & batteries we pair with

Whichever inverter brand you choose above, here's what typically goes alongside it.

Process

How it works

01

Message us

Tell us your home size and roughly what you pay Eskom or your municipality each month.

02

Site check

We look at your roof, your consumption, and your board before quoting anything final.

03

Install

Panels, inverter, and battery installed and commissioned by a registered electrician.

04

Bill drops

You generate your own power by day and run off the battery at night, so the next tariff hike lands on a much smaller bill.

Ready to stop paying more every year?

Tell us roughly what you pay Eskom or your municipality each month and we'll come back with an honest answer on what size system actually makes sense — and what it would save you. No charge, no obligation.

Rather chat on WhatsApp Quickest if you already have a photo of your bill or your board.

Inverter

Sunsynk

Sunsynk Hybrid Inverter Product photo coming soon — icon shown as placeholder

Step 1

Choose your inverter size

Rated output 5kW · 6.5 kW max PV input · generates roughly 20–25 kWh/day with a matched panel array in typical SA sun. Real-world output varies with roof direction, shading, and panel count — final number confirmed at site assessment.

Step 2

How many panels?

10 × 450W = 4.50 kWp array · range for this inverter: 4–14 panels

Minimum and maximum are set by this inverter's MPPT range — too few panels won't reach startup voltage, too many will exceed the max PV input.

Step 3

Choose a compatible solar panel

Step 4

Choose a compatible battery

Step 5

Battery capacity

2 × 3.55 kWh modules = 7.10 kWh total · up to 16 in parallel on this brand

Batteries connect in parallel, just like inverters — add more of the same brand's module to grow the bank, there's no fixed size. Exact parallel limits vary by inverter and battery firmware; confirmed at site assessment.

Estimated runtime for each appliance running on its own, on a full battery. Real homes run several things together, so actual backup time is shorter — this is a guide, not a promise.

Wifi Router 10W ~27 days
