I have been dealing with Sunsynk support locally and have really been disappointed with the service, and in fact the product, can anyone point me in the direction of someone senior at Sunsynk that I could approach to assist me sorting out this faulty inverter.

Hi Dean. What's wrong with your inverter. 

@Dean

Try phoning the other local SunSynk numbers or the SunSynk UK office:

What I have recently found out is that Sunsynk does not want to deal direct with the end user. They want the end user to deal with the supplier where you purchased your inverter from. This  was a bit disappointing to find out because I don’t know if all the suppliers are able to handle technical issues.

That's a bit of a bummer. I'm based in Zimbabwe and nearest dealer or supplier would be SA, so if they start giving me problems and then manufacturer is reluctant that's no good. What also happens then with warranty issues? Suppliers tend to refer end-user to manufacturer and are not always prepared to assist sometimes.

I am also concerned about this with the speed that suppliers open and close these days, what if your supplier closed down how do you deal with Sunsynk.

Personally, I think that the support is great, suppliers / installers affiliated with Segen have a Whatsapp group for Sunsynk, and another for Deye. Not sure about other distributors. Literally round the clock support, weekends too. And there are technical support centres in major cities.  

If that does not help:

Jean Joubert, Sunsynk / Deye technical manager, contact details (incl. cell number) here https://www.sunsynk.org/post/i-would-like-to-welcome-jean-joubert-to-sunsynk-sa

David Drake, Global Tech / Sunsynk director for Africa, contact details (incl. cell number) here:  https://www.sunsynk.org/post/i-would-like-to-introduce-david-drake-the-new-global-tech---sunsynk-director-for-africa

Is your problem not with your installer / supplier?

Often the problem is with the installer and not necessarily Sunsynk. 

I was going to suggest the bottleneck is your installer and to by-pass him/her and share threads of your issue if they are not playing ball. On a separate but equally important issue, hopefully am not hijacking your thread:

The 5kw Sunsynk inverter mentions that one needs a 150v PV array for the inverter to start up, I only have 3,000watts (250w panels x 12) which is roughly 56.25v, does this mean that I am unable to upgrade my system to a 5Kw Sunsynk system? Due to limited roof space I am unable to add more panels, is there a work around? PLEASE HELP.

!50V is indeed startup voltage for the 5.5K Sunsynk.

Please provide your 12 panels' full spec sheet,as well as your location information in Zimbabwe (longitude), and (if possible) past 10 years' minimum temperatures at say 10H00, so that we can estimate and suggest a reasonably sustainable configuration. Azimuth (North facing is 0 degrees) and panel tilt (roof pitch in degrees) would also help.

Note that if panels are "roughly 56.25v", the 150v plus is easily achieved by configuring 4 strings with 3 panels in series. But we need the full specs to be sure. 

My location is:

17°47'36.0"S 30°59'45.4"E

-17.793344, 30.995948

* Panel tilt is 15º

* 31ºNorth East is my roof line where I have 8 x 250watt Panels

* 226º South West, I have 4 x 250watt Panels

* Average minimum temperatures, would be a "guess-timate" - at 10H00 in winter it's about 10ºCelsius, Summer 20ºCelsius.

Interestingly, I appreciate that the Sunsynk is a more efficient inverter, but am wondering if truly solar on the whole is a good return on investment. I know for blackouts it's great, but I already have a Chinese MPPSolar/Axpert-type inverter and am thinking given budget constraints, may be good to continue limping along with it till it eventually packs up and then upgrade my inverter and other components to lithium. I'd love to meet someone who's satisfied/happy with their ROI, apart from the joy of electricity 24/7/365. What's your take?

Thank you.

Please provide a link to the panel's spec sheets? Or at least manufacturer and full model #? There is important info on it for sizing an array.

It depends on two things, where one's priorities lie, and what one's needs are, and both are different for every individual. It's similar to transport, some require their own transport for their livelihood, some for shopping only and others only for recreation and comfort. Some own Mercedes Benz, some own a Toyota, some use a bicycle, and some don't even own a car and use public transport. Every one's needs are different.

Back to priorities: Some complain about the high cost / low ROI of alternative energy, yet they value owning 3 motor vehicles, fine dining, wearing the latest fashions, and living in the trendiest suburbs. Everyone's priorities are different.

Personally, in order to generate an income, I need a reliable power supply. The local utility in South Africa is not reliable, and after an analysis of its economics, along with its idealistic and politically driven vision, the prognosis is not great, both in terms of reliability as well as cost.

On reliability, generating my own power is a must, because it is linked to my income, so in accounting terms it is an off-balance sheet expense, not an investment. So I don't look at the ROI, because that would feature on the balance sheet.

On the ever increasing cost of electricity, I took a business decision to stabilise my expenses, today, and for the future. I forecast double digit increases in electricity costs. Having my own generation is far easier to budget for.

So that's my business case, and it makes sense for me. Using ROI for my business case does not work, the I in ROI stands investment, which it isn't, to me it is an expense.

I concur on multiple points with your logic. Just it's frustrating when trying to juggle multiple areas especially punitive socio-political ones. I too rely, for my business on having a reliable power supply and internet connectivity. Just as I invested in solar, to create a stable power supply, my ISP stops investing in their redundancy infrastructure. So now I find I have power for my router, but their substations switch off during a black out due to not investing in generators or even solar systems. Frustration building I guess and now that I have to replace my batteries as they have reached end-of-life, over time and research I have discovered my initial Solar system contractor did a shoddy job, meaning it's literally having to start all over again and the cost is high, not to mention the fact that now some of the earlier invested hardware is getting obsolete and newer better technologies like lithium and more efficient inverters are now on the market at substantively higher costs. C'est la vie (such is life).

So now the hard choice is do I invest in gel/agm batteries and limp along till I can afford to overhaul my system or do I begin by buying the inverter and rewiring my panels plus adding system protections which were not initially incorporated and at the same time plan to move from my current ISP to a more expensive one who can also be erratic and not provide a good service level agreement in terms of attending to faults (Rhetorical question)?

I’m very disappointed with sunsynk inverter, when you have problems is very hard to find help, no mail reply, let you on limbo between you and customer. How you can create product easy to locked out all inverter stop working and with out any solutions how to reset . 

Can anyone help me with a user whatsapp forum for solar power in south africa? I need to understand lots if technical issues around solar before i commit. Not from a supplier but from users .
