Sunsynk manufactures solar inverters and batteries, with a South African office in Randburg, Johannesburg.
A grid-tied solar installation must be registered with your municipality or Eskom, and requires a certificate of compliance from a registered person.
An unregistered installation can attract a penalty and can invalidate a household insurance claim. Counterfeit inverters exist, so buy through an authorised distributor and keep the serial number.
This page covers how to contact Sunsynk in South Africa. The details below were taken from the official Sunsynk contact page rather than from any third-party directory.
ContactDetails.co.za is an independent directory. We are not Sunsynk and cannot act on your behalf. Everything on this page is a routing aid so you reach the right official channel quickly.

Self-service options before you call
- Check the official site at sunsynk.org, which carries the current contact details and any online enquiry form.
- WhatsApp on 081 335 3005, which works over wifi and leaves you a written record.
- Email to [email protected], which gives you a written record of what you asked and when.
- Calling outside peak times. Monday mornings and the hour after 17:00 are usually the worst for South African contact centres.
What to have ready before you call
- A clear one line summary of what you need resolved.
- Your account, order or reference number if you already have one.
- The identity document or account holder details, since most South African providers verify who you are before discussing an account.
- Dates, amounts and any error message exactly as it appeared.
- A pen and paper for the reference number. Ask for one every time, because without it a follow up call starts from nothing.
Industrial and hazardous material incidents
- A chemical release, a gas leak or a plant emergency is not a police matter first. Dial 10111 or 112, say what the substance is if you know, and say how many people are affected.
- Move upwind and away before you make the call. Distance is the only protection available to a member of the public.
- Do not switch anything electrical on or off near a suspected gas leak, and do not use a phone in the room. Both can provide an ignition source.
- Major installations must have emergency plans and must inform the surrounding community about the risks and the warning arrangements. You are entitled to ask what they are.
- Report ongoing pollution to the provincial environmental department, with dates, photographs and a precise location. A general complaint is far harder to act on.
The Environmental Management Inspectorate, the Green Scorpions, enforces environmental law and can act on a documented pattern of incidents where a single report gets no traction.
Complaints and escalation
If a first call does not resolve the matter, escalate through the business’s own complaints process first, in writing and with a reference number. Unresolved consumer complaints go to the Consumer Goods and Services Ombud on 0860 000 272, free of charge, and the National Consumer Commission on 012 065 1940 handles contraventions of the Consumer Protection Act.
Keep a short written log of each contact: the date, the channel you used, the name of the agent and the reference number. Most consumer complaint processes ask for exactly that history, and having it ready is usually the difference between a fast resolution and starting over.
Avoiding fake Sunsynk contact numbers
Contact details for well known South African brands are a common target for impersonation. Numbers that look official appear in search ads, social media replies and cloned websites, and the person answering is not Sunsynk.
- Reach Sunsynk through the official site at sunsynk.org rather than through a number in a search advert or a social media reply.
- Sunsynk will never ask you for your full card number, PIN, CVV, online banking password or a one time PIN. Nobody legitimate needs those to help you.
- Treat any caller who creates urgency, asks you to install remote access software, or asks you to move money to a safe account as fraudulent, and end the call.
- If you are unsure whether a call was genuine, hang up and dial the official number yourself rather than calling back a number the caller gave you.

Frequently asked questions
What is the Sunsynk contact number?
The routes are listed in the table above, with what each one is for. The main route is +27 10 100 3589. Confirm it on sunsynk.org before relying on it, since numbers are changed from time to time.
How do I know a Sunsynk number is genuine?
Check it against the official site at sunsynk.org. A number that only appears in a search advert, a social media reply or a third-party directory should not be trusted for anything involving your account, your money or your identity document.
What should I do if nobody resolves my query?
Ask for the complaint reference and the escalation path on your first call, then follow the escalation route described above. Keep the dates, agent names and reference numbers, because every formal complaint process will ask for them.
Can ContactDetails.co.za resolve this for me?
No. We are an independent directory, not Sunsynk, and we have no access to your account. Everything here is a routing aid so that you reach the correct official channel with the right information in hand.
Is there a cost to calling these numbers?
South African 0860 and 0861 numbers are charged at a share-call or standard rate depending on your provider, and 0800 numbers are toll free from a landline. Calls from a mobile are billed at your own operator’s rate, so check your plan if cost matters.
