8 meters of 10mm cable into such a small space is no joke 🤣

Almost done with the wiring.

Welcome to my world🤣 wait till you get to 16mm² armoured then it is fun and games. Looks good, home automation journey the way to go good solid product.

Yeah, I can well imagine that now.
I told my electrician on the weekend that it will take me a day to wire up this DB, he laughed at me...
I am now on day 3 and still not done.

He will have the easy part, checking my work and then connecting the circuits to this new board.

I know the feeling. The last installation I did took me more than a week with moving everything and separating it into multiple DBs. It does leave you with a feeling of accomplishment, though. I still don't want to do that every day. :)

DB Wiring done and tested Eskom Side and Inverter Side :)
Now to get the electrician to come test and connect everything :)

Eskom Side

Inverter Side

Well done @WannabeSolarSparkylooks good. Just some advice as to run bare copper earth conductor past the front switchgear terminals. It more a case of best practice than illegal or must not be done. Should a sparky use non insulated shaft screwdriver on one of the live terminals and should touch the bare earth wire bam short curcuit. You could either re route the bare earth wire around the back of the switchgear or use green/ yellow insulated earth wire.

Question? I have circled in yellow that i assume is your earth/neutral bond it almost looks from the angle of the pic if the earth wire is running from the top of the spd to the contactor and i dont see a neutral wire on the contactor. It is always diffucult with wiring to get the full picture from a picture taken. Many happy Sonoff days.

@TaliaB advice, suggestions, recommendations are always appreciated :)

New insulated earth wire is already on order :) And will be running below all the other wires.

Bonding relay will be wired when the connection to the inverter is done, that top right part (Pretty much the breakers, spd etc in your yellow ring) will be done by the electrician when he connects the inverter incoming and island signal wire for the contactor.

As for those sonoffs spm relay-meters, i have been running them for almost 2 years already on my old DB, they are awesome.
The geyser one in the pic is new, its replacing my old powr3 with the new powr320d as I have replaced the geyser element with a lower wattage one which draws much lower amps.

I wish Sonoff Africa can correct their circuit wiring details. Load and SONOFF neutral wiring in blue errors. 

Looks correct to me on their website?
Neutral black on photo, and Neutral blue on diagram.

Unless you referring to this image?
In which case i think it is simply their graphics guy who made a mistake extending the blue neutral over to the live on the left diagram.

Wow pretty decent sensor, it even measure tiny loads. And matches exactly what my multimeter says, will have to check on a full 50 amp load to see if it needs further calibration.

Nice i would like to see the power factor at 50A at the moment with very low current the power factor is half power used half wasted and you pay for it. Looking forward to full load Eskom feed parameters.

POW and the CT on the same power feed and phase for accuracy.

Yip that fancy new pow with ct is only connected to eskom incoming, mostly though that nice new meter is hardly ever on as my eskom is manually switched off most of the year 🤣

It measures quite accurately as compared with my fluke meter :) needed a small calibration but now measuring great, for my domestic use anyway :)
