Inverter repairs in Johannesburg and across Gauteng
When the power is out and the inverter is not carrying the house, write down the fault code and check a few free things first. Then WhatsApp us a photo of the screen and we look for an installer near you.

A solar installer near you phones you and quotes before any work starts. Nothing to pay to be put in touch.
What this usually involves
Read the screen before you reset anything. Write down or photograph the fault or error code. It is the most useful thing you can give a technician, and resetting can clear it.
Overload is the most common fault. A kettle, a geyser, an oven or a heater on the backup circuits can ask for more than the inverter can supply, and it shuts down or beeps. Switch the heavy things off and see if it recovers.
If the batteries ran flat in a long outage, the inverter may sit waiting for them to recover. Some lithium batteries switch themselves off to protect the cells and need to be woken up from the battery itself. Check the manual or the battery's lights before assuming it is broken.
Check the breakers and isolators on the inverter's own board, and the battery isolator. Do not open the inverter. It holds high voltages from the batteries and the panels even with the mains off.

How it works
- 01
Tell us what you want running
Not what size system you think you need. What you actually want to keep on: fridge, lights, wifi, geyser, the whole house.
- 02
An installer sizes it
A real load calculation off your bill and your usage, not a package picked off a shelf because it is what they have in stock.
- 03
A written quote
Itemised: panels, inverter, batteries, mounting, labour, CoC. So you can compare it against anyone else's.
How we check an installer first
- We speak to them before your jobBefore your job goes to an installer, we find one near you and talk to them ourselves. That is a different thing from the PV GreenCard register on this site, which is a public list of accredited companies and most of the companies on it have never heard of us.
- We check their public recordTheir existing reviews, their trading history and whether the business is who it says it is. If we cannot find any of it, we do not refer to them.
- We stop referring to anyone who lets you downTell us what happened. If they let you down, we stop sending them work.
That is the whole list. We are not going to show you a badge for something we have not done, and we are not going to call a company checked because it appears on somebody else's register.

- CoCcompliance certificate on completion
Solar247 is not an installation company. We are a Gauteng referral service that finds you a local installer, checks them and stays out of the way. You deal with them directly and pay them directly.
What decides the price
A solar quote is the easiest one in the trades to mislead somebody with, because almost nobody can compare two of them. These are the things that actually decide the number, and the questions that make two quotes comparable.
| What you want to keep running | The whole price, more than anything else. A system to keep the lights, wifi and fridge on through load shedding is a different object from one meant to run a geyser and a pool pump. Give every installer the same list or you are not comparing quotes. |
|---|---|
| Batteries | Usually the single biggest line, and the one that varies most between quotes. Storage is priced per kWh, so ask for the kWh figure rather than the brand name. |
| The inverter | Its size, and whether it is hybrid, grid-tied or off-grid. An inverter sized for the panels you have today but not for the ones you will add is a cost you pay twice. |
| The roof | Tile, IBR or flat changes the mounting and the labour. So does the pitch, the direction it faces, and how far the cable has to run back to the DB board. |
| Paperwork | An electrical Certificate of Compliance, and SSEG registration with your electricity supplier. City Power asks for solar systems to be registered and makes no exception for zero-export ones. Ask whether both are in the price or extra. |
Worth asking, before you say yes
- Can I have it itemised: panels, inverter, batteries, mounting, cabling, labour, CoC?
- What is the battery in kWh, and what is the usable depth of discharge?
- What are the warranties on the panels, the inverter and the battery, and are they the manufacturer's or yours?
- Is SSEG registration included, and who submits it?
- Is that including VAT?

Questions people ask
Why does my inverter beep?
Usually it is warning about overload, low battery or a fault. The pattern of beeps and the code on the screen say which, and the inverter's manual lists them. Overload is the easy one: switch off whatever heavy appliance just came on.
Can any installer repair my inverter?
Many faults are in the wiring, the settings or the battery, and any competent installer can find those. If the inverter itself has failed and is still under warranty, the repair usually has to go through the supplier, so have the model and the invoice ready.
Are you an installer yourselves?
No. Solar247 is a referral service. We find an installer near you, check them, and pass your job on. They contact you directly. You deal with them and pay them, not us.
What does a system actually cost?
Anyone who quotes you a number before seeing your bill is guessing. It depends on what you want running and for how long. A backup-only setup and a full solar installation are very different prices, which is why the first step is a look at your bill and your house rather than a figure.
Do I get a compliance certificate?
You should, and you should insist on it. Solar and inverter work is electrical work. A Certificate of Compliance protects you, matters for insurance, and you will need it when you sell the house.
Does my system need to be registered with the municipality?
If it is grid-tied or hybrid, yes. The registration goes through whoever supplies your electricity: City Power for most of Johannesburg, the City of Tshwane in Pretoria, your own municipality elsewhere in Gauteng, or Eskom wherever it bills you directly. It is the installer's job to handle, but ask to see it done rather than taking their word for it.
Can I start with backup and add panels later?
Usually yes, and for a lot of households it is the sensible order. Tell the installer that is the plan up front so the inverter they put in can take panels when you are ready.
Do you cover my area?
All of Gauteng: Johannesburg, Pretoria, Ekurhuleni and the East Rand, the West Rand, the Vaal and the areas in between. We look for an installer near you, and if nobody is close enough to be worth your time, we tell you so. Outside Gauteng? Send a message anyway and we will tell you honestly whether we can help.
What happens to my details?
They go to the installer who is going to phone you, and nowhere else. We do not sell contact details on. Message us and they are removed.
Why are other solar installers listed on this site?
Because the PV GreenCard register is public and useful: it lets you check that a company is certified before you sign a quote. We show the certified companies near you. It is not a list of who we recommend, and most of them have never heard of us. If you want an installer, WhatsApp us and we look for one near you. Any company on the register can have its entry taken off this site for free by sending one message.
