Thanks for clearing up @Coulomb. Much appreciated.

Thanks @JayN! Really appreciate the feedback.

Thanks @Chris_H! Exactly the conformation I was looking for.

If I can jump in offside here.. I have a question on this inverter; its not Hybrid, so can you cannot feedback into the gird, which is fine. However, can the source be as PV first with grid to supplement if PV generation is not enough? Or is it either grid or PV? Thanks.

Thanks Sc00bs Not looking to convert tho. I have my workshop on it's own cable and split from the house just inside my boundary wall so I can do anything I want to the house without impacting the workshop and it's three phase loads. I use the three phase fairly extensively there so a VFD per device will probably cost as much as an inverter.

Don't blame you ... that part is suspiciously hard to find in all their documentation...

Hi @JayN @Chris_H Looking at starting with this same setup. I might start with a couple more panels since we are energy hogs. Question; did you downgrade your geyser element(s)? I only have one but it has a 4 KW element and currently resides on the same phase as my stove so not looking forward to someone switching on the stove while the geyser is on. Also; did you install yourself? Thanks.

I had a look but could not find any literature about unbalanced loads on the Goodwe - I had the same situation on the SunSynk for that matter. On the SunSynk it was 100% unbalanced but to a maximum of 50% of the entire inverter capacity so 6KW max on a phase. I would assume the same applies here so 5 KW. Might be a tad shy..

So yes, an on-switch anywhere will complete the circuit and your neutral anywhere is not so neutral anymore, I get this. What I've never quite grasped is if neutral is grounded, how does this not complete the circuit to ground? Where is ground picked up in the first place?

It's already on a timer; had a solar panel on it that popped last winter and I did not replace. Now the solar control panel is a glorified timer; I figured before I go solar water heating again ( I did not have a good experience), I'd rather install a heat pump and if needed add a couple of PV panels to cater for the ~1.5Kw draw. But in the interim, yes, downgrading the element is an option. It will take forever to heat up in winter tho so will have to rework my schedule.

Hi guys I've been trolling this and other forums for months and I have been in analysis-paralysis phase for almost two years. The kicker is my Eskom bill jumping a couple of months ago for a reason I am yet to figure out. Regardless, this has changed my approach to this whole exercise so might have been a good thing procrastinating. I have three phase in the house and even though I do not have three phase loads in the house I do have 3ph loads in my workshop which is out of scope for this consternation. I am not convinced going single phase is the way to go so I am sticking with 3ph. But this complicates things... I am 'writing off' the cost of an inverter + battery + installation - with capacity to get me through load shedding - as a base cost of living in SA. Just like insurance and a fence around our properties it's one of the things we pay for to make up for all the other benefits we get. Once past this point I look at payback periods etc. So initial install I was looking the SunSynk 12KW 3Ph inverter with the 5.5KWh Hubble battery. From this forum it looks like a winner and the fact that it supports unbalanced load swayed me from three single phase inverters. Challenge is, even with the 6KW capability on one phase, I do not like the odds of someone switching on a stove while the geyser timer is on. I could have the stove on one phase and the geyser on another but I just see things going very wrong... I would love someone correcting me on this assumption. So back to single phase inverters and will probably go for the SunSynk/Deye options. Add to this as many panels I can fit into my initial budget as I recon offloading most of my daytime load to solar and dumping excess in my 200l geyser works to start off with. I will look at more batteries later but realistically I will never get off grid with my workshop activities so I am all about getting as much out of solar as possible, realizing there will be a ceiling. I bought my house with my DB setup for a single phase generator: so one phase has my geyser and stove. The other two phases runs everything else so when I swap over the changeover switch it bridges the input of these two phases from the generator and the stove/geyser phase is dead. The plan is to get two Inverters for the two phases with everything and leave the stove and geyser as is on the last phase. So here is my plan attached, high level. Couple of things that I am worried about; 1) When supply dies, I see a neutral going back to the supply. Neutral can tickle you... ask me how I know. 2) I do not see a way of dumping excess into my geyser. I am sure this has something to do with connecting it to the non-essential side of an inverter but its a 4 KW element, with the potential of someone switching on a stove at the same time. So all of this through the inverter with whatever else is running on the plugs as well. Surely this will release the magic smoke? 3) I am sure I missed more... feel free to educate me. 3a) Will this pass CoC? Thanks all!
