OK, will ask the installers to check. From what I've read elsewhere on these forums it sounded like fitting it the wrong way around would result in the values inverting (being negative rather than positive) rather than disappear, but I'm desperate so hope that could be it. Also saw now that the CT is connected to 3 and 4 on the Deye instead of 5 and 6 suggested by some. Could this make a difference?

I hope someone can assist. I'm in the middle of my installation and have done a lot of research into what is possible or not possible with the Deye inverter. One of my aims is to channel excess PV production during the day to my non-essentials. For this I understand I should choose the "zero export to CT" function and leave the "Sell solar" un-ticked. When I do this on my inverter the load drops to zero and I can't see what energy source is used to power my home. I've also since realised that I can't see non-essentials on the load on the inverter and then when I select "zero export to CT" I don't see the essentials either. I know the positioning of the CT is important. The installer promised me its installed just after the main trip where the mains comes into the DB - so upstream from essentials and non-essentials. What am I missing or could it be the CT that wasn't installed as explained?

Thx. I had it the same which makes me think that isn't my problem. I'm not seeing inverted numbers, I'm not seeing any numbers. Any idea why the load would disappear?

DEYE manual shows the arrow should point towards grid?

Not sure, will have to check. I also get the feeling that it then stops using battery and goes back to grid because the SOC isn't decreasing

Hi. My system was installed today. I have a question wrt the "Zero export to CT" function on the Deye. This needs to be selected if I want to use excess PV to power non-essentials as far as I understand. What I see now though is that while I still have battery power available and this is being used to power my home, the DEYE shows that the load is zero. If I switch back to "Zero export to Load" it shows logical nrs again. Is this the CT that wasn't correctly installed? The installer promised me it was correct. As far as I understood from him he installed it on the DB just after the main switch.

Thx.

Thanks I understand that there will be days when I'll have to use the grid, no issues with that. Best I can do is plan for the good days I guess. Again my concern with geysers on non-essential side is I'll have to stay on top of load shedding schedules to see when it overlaps with my geyser times as they won't come on during these times. I want to get away from load shedding schedules. So on essential load geysers will use excess PV in the afternoons and battery/grid in the mornings. (On cloudy days it will use battery if there is else grid if there is - can't solve for them if there is none of that anyway). Does this make sense? Am I missing something? Wrt the load, can you confirm my understanding? I was under the impression that the 8kw limit is what the inverter can supply form battery/PV, but it can pass through additional power from grid on top of that. So overload only becomes a risk when geyser is on (4kw at most), grid goes off and I use more than 4kw in the rest of my house (unlikely during early morning or late afternoons)?

Even if I can heat the water during the afternoon, our largest warm water consumption is in the evening. Because the geysers will be off then it will fill or at least half fill with cold water that needs to be heated the following morning in case someone wants to shower. Can't see how I will get away from a quick burst in the morning, but will certainly check. My view is that its almost irrelevant whether the geysers are on essential or non-essential. In the afternoons I should have excess PV and in the mornings I'll use battery if still available and if not grid. I'll leave a little battery in case there is load shedding. Last option is to install gas geyser after electric geyser that can provide burst in the morning.

Thx, I'll check. And just to confirm again, the Deye will then overrule the SoC % in the Time of use setting? And it will do this when the grid goes down?

Must be honest I've read many negatives about the Aux output... Also doubtful if my installer would know how to do this. Let me perhaps ask why you you think its bad to use batteries for geysers? If all goes well I'll only do this early morning for a boost. I can always set the SoC to 40% to always have something left for after geysers are done? So it feels like I've got a lot of battery backup and can manage this effectively. Other issue I can think of is overloading? But this is only applicable during load shedding right? If I use more than 8kwh when the grid is there the Deye will just pass through grid power to supplement (up to 12kwh I believe)?

Do you know where to find this setting? Thanks for the help btw....

Sorry, should have read everything before replying. So when the grid is not available, do the system then not limit battery use as per the SoC in the Time of use settings?

My daily use is 45kWh. But that was before switching stove to gas and getting timers for geysers. I'll only produce 38kWh at 80% though. So I'll most likely deplete my batteries every day.
