Hi. I've got the exact same heatpump, exact same controller as shown in the photo and I'm sitting with the exact same problem. My heatpump is set to switch on at 3am and off at 8pm. Every morning at 3am it switches on (red light burning on control unit) and heats up to the set temperature. Once on temperature it switches off (red light goes off) but it doesn't switch back on when the temperature drops after using hot water like showering. I have to manually press the grey power button for it to switch back on. I'm not sure my marriage will last if I can't get this resolved. :(

So it was the CT. When the backup system was first installed the CT was just added to the DB board without really checking it's location as we didn't have solar yet. Then when we did the solar installation 6 months later we forgot to check it. All sorted now.

@Scorp007Thank you. Makes sense. Still struggling with the rest of the issues. I also now found out that if I tick the "Sync" box in the time and date settings, it will sync the time using the internet. Problem is that when it syncs it's one hour ahead. How do I change the time zone?

Just another note: With the setup in the System Mode screen as "Zero Export" ticked and "Prioritize Load" ticked and "Limit to Load only" not ticked, the inverter home screen with the dials doesn't seem to include the essential load into account. As soon as the geyser and pool pump (the only things on non-essential) are switched off, the AC load and grid blocs and dials would read 0. I don't have anything installed on the Aux side. Another weird thing: While the geyser is on, for instance, it will draw 2.8kw (read from smart timer switch), but the inverter would show a total AC draw of 3.38kw. With nothing else switched on on the non-essential side. If I change the System Mode screen an tick "Limit to Load only", the inverter home screen displays the power usage from my essential load and grid correctly, but the solar panels don't export to the non-essential load anymore.

Just tried that (moved them to 5 & 6) and then grid input show 0 (even with geyser switched on). When I move them back to 3 & 4 it shows grid draw, but way more than what the geyser is pulling. I've got the 5kw inverter.

Hi @bryan86, what resolved your issue? I have exactly the same symptoms on my 5Kw inverter. I checked the CT arrow as well as terminal connections and mine are correctly installed on 3&4 and settings on the inverter exactly as in the posts above.

Freedomwon tech support just updated my eTower firmware and everything is back to normal.

Hi KempM I seem to have the exact same issue as you. I got my Freedom Won eTower plus Sunsync 5Kw inverter installed and it's been running for a week now. But it's also been slowly loosing max SOC% since installation and now stands at 88%, with the battery voltage at 55.6V. While at the office the installer phoned and said I should set the inverter float and charge voltage to 55.8V and that should sort the problem out. Did you try that at all?
