Forgot to mention, a 12led string like that pulls about 170mA, so not bad considering the amount of light.
In the bathroom or passage I will only run 6leds, so <100mA.
For the 5 areas I have allocated these so far, I am pulling less than 1A, so with my current 80odd Ah battery bank, that should do swimmingly (y)
 

You are far too trusting of our benevolent rulers...

Registration precedes licensing (with fees attached), licensing presumes the ability to refuse a licence or to impose limits and conditions, including total denial of access.

Don't ask me how I know this.

Really liking your setup and photos man. Thanks for sharing with us.
Definitely bookmarking this thread, as my setup I am planning is going to be *very* close to this.

Yeah, I saw AvE's review, and know he does not shill at all, so calls a spade a f-ing spade Was a bit disappointed to see that he did not rate it at all, hence asking here!
As mentioned too, if compared to my old MT21, this thing should be miles ahead...
 

Nice. Whereabouts are you based?
Keep the pics coming!

What @plonkstersaid holds true in terms  of costs.
But, nothings ever black or white,  it should be weighed off against performance.
For example, say there is fixed object shading of a panel ( say by an chimney) that knocks out a string's production for a portion of a day.
It may just be prudent to have 2/3 production from 3 strings instead of half production from 2.
 

Correct.
Pretty much cabling. Thinner, and less of it. Also depending on where you live each array might require its own surge arrestor. Each array also needs its own DC switching, fuses, and so forth, so more strings means more of everything , not just cable 🙂

Yeah, mowing the lawn actually
 
Thanks for all the assistance so far guys, really liking the whole journey here. Now that ship just needs to make a move on so that I can start applying the learnings.

Not too far from you, someone I've been in contact with once...

Heh. Nope, I have no-one Want to DIY as much as possible within reason, but understand that regs require signoff and the like.

Thanks to both of you for the advice.
 
Now to find a decent sparkie. Anyone have recommendations in Centurion perhaps?

Thats a very old, very large earth leakage unit, the newer CBI earth leakages will only take up 2 modules and not 4

You could also swop the double pole geyser circuit breaker to a single pole circuit breaker, (https://www.builders.co.za/Electrical/DB-Boxes-%26-Circuit-Breakers/Circuit-Breakers/CBI-Circuit-Breaker-25a-3ka/p/000000000000009844) provided that the geyser has a double pole isolator switch before the cable enters the heating element (https://www.builders.co.za/Electrical/Wall-Plugs-%26-Switches/Switches/Lesco-4x2-30Amp-White-Isolator/p/000000000000567322)
 
 

... I'd still say, now is as good as it's going to get, as you're wiring into your DB you need to get a new CoC done, which will cost... so do it now, get a 3 rail (12 or 18 place) DB box, cat the back out above and below the middle rail and fit it over the hole that you will have once you've removed the current DB panel.

But for an average user out there who can hardly hold the correct side of screwdriver but wants to DIY the Efergy wins hand down. You sacrifice accuracy for safety as you only clip a simple CT around a cable. No touching or physical connecting to any live conductor.
 
Minerva is computer guy so he could probably wing you suggestion
