Have used Ricardo from wire2wire personally, highly recommended

Thank you for the suggestion; they addressed the electrical problems. It appears that the initial installer failed to include an earth-neutral relay and a surge protector in the installation. Additionally, the cabling and fuses used were inadequate for the recommended specifications. Moreover, the installer connected one of the plug circuits to the geyser, which resulted in the socket lacking proper grounding, causing it to trip the earth leakage when under any load.
 
So I have a 3 phase electricity supply and I was told I should look at the 12kW inverter since it is 3-phase.
That is around R50k for the 12kW, but if I add another R4k I can get the 20kW one. The price difference is "negligible" compared to a 5kW vs 8kW ones.
What are the issues I might face with the 20kW one?
 
The 20kw uses high voltage batteries. So you'll have to compare batteries and see what the HV options are

I also have 3 phase power and had the 12kW installed. You really need to be, stupidly, pushing your consumption in order to have issues with the inverter.

The actual constraining factor on the inverter is your available off grid power. To really utilize the 12kW/20kW your are going to need sufficient panels to produce that in the day along with enough batteries and sufficient discharge rate.

Instead of going for the overkill it would be better to just manage your consumption

So the inverter itself was fine after all?

I also have 3 phase and find that the phase that has a geyser and the kitchen on it does occasionally run into the '6Kw max on a phase' limitation (I use smart plugs and HomeAssistant to prevent trips).

From what I can see, one HV Battery (20Kw) is equal to about 4 'normal' 5Kw batteries and costs about the same.

I haven't seen many references online, but a 192V battery is basically 4 X 48V batteries in series, with a modified BMS. Probably not many sold, since it's a niche market. See:

192V high voltage lithium ion battery for solar energy system

Guys, when cleaning your panels - are you disconnecting your panels?

No.
By washing, I mean squirting them off with a hosepipe. No brooms / mops / squeegies /soapy water / pressure washer involved, I would rather not damage them.

The inverter functions properly; however, there were installation and wiring issues. Despite being recommended by others and listed as an approved installer on the Sunsynk website, the installation was subpar. Compounding the problem, the builders of the house ran both the geyser wire and bedroom electrical socket wires in a single conduit, and so the installer just joined wires without truly understanding what they were doing.

Should let Sunsynk know, so that they can review the accreditation and see that the guys get training. They have a free training facility in Randburg.

I believe someone got there before me; they're not listed as an accredited installer anymore.

20kw is overkill. The device itself will probably chew a bit of that power. Go with the 12 IMO.
