Thank you kind stranger on the Internet from 4 years ago. You have made my day. I moved into a new house with this setup about four months ago and was unable to shower between 09h00 and 15h00 when the collector gets sun. The valve on my side sits at the cold water exit (well actually it is just connected to the geyser's cold water inlet). When showering and the pump went on, there would be a sudden inrush of extremely hot water followed by water too cold to shower in (even on full hot open). Now that I have partially closed that valve (even though I am a bit worried that it is on the "vacuum" side of the pump), I can still feel the effect when the pump kicks in (slightly colder), but is is much more bearable. The only way I can explain it it my mind, is that the municipal pressure overcomes the the water pump pressure and runs in reverse through the collector. Does anyone here know if the pump blocks flow when not powered? The water pressure in my area is quite low (3.5 Bar at the meter) so I have a suspicion that the battery on the 12V side or the pump might be on it's way out.

I am sitting here watching the app temperatures like a hawk hoping the whole setup doesn't explode. Wish me luck and thanks again for the advice.

I thought I should share this experience here. From what I heard, Sunsynk is generally a good brand and good value for money. I know quite a few people who have installed them and have had no issues. 
I installed an 8kW unit (along with 2xHubble 5.5kWh batteries and 10x550W panels) in January this year. It was working perfectly for about 4 days and then I received a DC overcurrent fault notification from the app. The installer had a look and tried resetting everything but kept getting faults. They disconnected the batteries (they seemed to start up just fine when not connected) but measured a dead short over the battery connection terminals on the inverter. Everything was logged on the app and all the important stats were well within the limits of the inverter. I was of course disappointed, but I understand that these things can happen.
The inverter was sent back to Sunsynk for replacement/repair on 23 January 2023. The installer did speak to them by phone to explain the situation and asked if they could expedite or provide a loan unit and they said they would see what they can do but the it might take up to 3/4 weeks. The installer sent weekly emails to follow up. The only response we received was a request for the serial number of the unit. After 4 weeks we received a response saying the unit will be ready the next week (this was almost 3 weeks ago). It is now more than 7 weeks since the return was logged and my last 4 emails have gone unanswered. I have essentially been ghosted. They have not provided any information on the reason for the delay or what the problem with the unit is. Only one short response saying the unit is being repaired should be ready "next week".
I don't know why this is being repaired instead of being replaced. They won't tell me that or who made the decision. I am really frustrated with he situation and their response. What really gets to me is the complete lack of feedback. When the install was done, my old 3kVA inverter with battery backup was disconnected from the essential circuits and it was reconfigured to run the whole house. When the inverter failed, I was under the impression the whole time that it would be replaced "soon". It just didn't make sense to re-wire the db and re-wire it again the next week when a replacement came. Even if they just let me know it would take two (or more) months to attend to it, I could have made alternate arrangements (renting one or buying a replacement for the meantime), but you are continually stuck in limbo.
Apologies for the rant. But I think people should know what they are getting into when they buy this brand. It is extremely frustrating.
