Unit was repaired under warranty. No real explanantion by Sunsynk what exactly went wrong with it. Took them 5 weeks. As for the the overload, it wasn't overloaded after all. Unit just failed.

Somebody should go to the roadshow event and pose the questions raised here.

Yeah, as per the other thread. Inverter has been with Sunsynk since 5 Dec 2023. Excl holidays, it's already 3 weeks. Can't see it being ready this coming week either. Sunsynk support seems completely broken. All aspects of it. Support is broken. App/data is still broken. Seems they might have some serious internal issues tbh.

I phoned (calls are recorded for quality purposes) and the UK sounding support lady told me their turnaround time is 2 weeks. I then asked why I've been waiting 4 weeks now. She said they closed over Christmas. Fair enough. But I knew this, and my unit was there 2 weeks before they closed. A week after they opened again, she now told me it's going to take another 2-3 weeks, because of the "backlog". In short. I'm not upset. Lesson learnt. Will stay away and not recommend their products in the future. If it breaks again, will pay for another brand without hesitation.

This seems to be what installers are recommending now. Good hardware, let down by poor service.

My inverter failed end of Nov 2023 after exactly one year. Was promptly sent to Sunsynk by my installer, which Sunsynk confirmed they received on 5 Dec. Phoned today again. Support lady confirmed they had roughly 2 weeks before the Christmas holiday to repair. Apparently, it's going to take *at least* another 2 weeks (probably more, because of a backlog according to her). Not impressed. @Keith Gough

How do I check this with my installer? My unit failed 30 Nov and I'm still waiting for feedback from Sunsynk via installer.

Thanks for the replies so far. To answer some of the questions. Still waiting on installer to confirm when they can remove the unit and send in. Nothing has been decided in terms or what caused the failure. The initial emails were from a tech at the installer, who I assume is still junior. It's a professional install, but I'm not getting a warm and fuzzy feeling about the support process thus far. I'm 99% sure we didn't overload the inverter. There was no alarm that I know of, but I've also never really checked the settings for that, since I know our essential loads are well below the max of the inverter. I assume the installer knows what they're doing with setup. Thermals were fine. I would say typical for the fanless units. I think I saw high 50's and mid 40's for DC/AC temps. Nothing that looked remotely what I would call too high for these units. We always ensure that the inverter has plenty of airflow and open the side door of the garage for a breeze to cool it down. I also checked previous days earlier in the year where the loads showed almost 9000w. Again, mostly non-essentials and in those cases what was pulled from the grid was everything above 5000w. So how I expect the inverter and installation to handle it.

More details. I don't understand why this would have been an issue? If the load is higher than 5000W, then surely that would have been supplied by the grid? The inverter should supply up to a max of 5k, and the grid the rest. We're not talking thousands of watts here. We're talking less then 500w....

Hi, My Sunsynk 5kw seems to have died yesterday. Just the blue light at the bottom switches on. Display and LEDs above display are dead. No output from inverter. We have essentials and non-essentials. Pool pump, geyser, microwave, aircon (big), washing, dishwasher, etc. all on non-essentials (i.e. dead when there's loadshedding). Yesterday the (non-essentials) pool pump (750w), aircon (big) and washing machine was on. I think the load on the essential side was probably no more than 2.5kw (PCs, small aircon). Someone at installer sent me this, saying we overloaded the inverter and would potentially have to pay for repairs. I don't see how we could have done that? Thoughts?
