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.

Just finished setting up my new sonoff POWCT Ring with tasmota, wiring was not an issue 🙃

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.

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

@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.

My inverter and batteries have been on holiday for almost a week now. Almost time for them to get back into production again.

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

Cloud edge scatter affect. Partly cloudy days scatter the suns rays more so you have light dropping onto the panels from more angles than just direct.

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.

8 meters of 10mm cable into such a small space is no joke 🤣 Almost done with the wiring.

If you are in a hurry to sell, then you should consider below R20K Most new batteries with the same or better specs are now retailing under R20k

This comes to mind... Nodered for all the logic, some smart devices to gather required data and some DC high amp solid-state relays or old school bulk copper relays.

All morning to do just some of the load side wiring. Much respect for electricians who do this everyday.

Getting ready to wire up my new DB Still need to decide on where exactly to put the new SONOFF POW Ring Smart Power Meter which will be monitoring the main Eskom incoming line.

Yip solar does teach you to use power more efficiently and find those weird energy drains.

Same chemistry and same voltage then should be ok.

for that rs485 you would use the 3.3v power usually at pin 1 on the esp, using the vin may be too high voltage and could end up damaging. From the datasheet for that module: SP3485 / MAX3485 are RS485 transceivers requiring 3.3V power supply.

Yes, that is usually the voltage from the usb supply, the esp32 has a voltage regulator that takes vin down to 3.3v logic voltages that the board runs on. Depending on the layout config the vin can be up to 12v

Time to tasmotize that All my sonoff devices push data out at 10 second intervals, some of the critical ones do once every second and all local without need for internet.

I try to do mine every 6 months. But since using the jkbms i noticed they do not really go out of balance

Yip that is quite a very good possibility as well. @Buff have you checked the sunsynk error logs, that should point you in the direction of the reason for the trips.

That would be a good point to test if it is the geyser causing the trips. If they geyser is isolated(Switched off) and it then still trips then most likely you have a E/N bonding issue.

Sounds like geyser is on the essentials side, this is usually ok BUT only if the loads are then managed correctly and operation fully explained by the installer. In most installations the geyser is usually on the non-essentials side along with other high load appliances like e.g. the stove. I have mine on the essentials side, BUT it is smart controlled to prevent the issue you describe. OR!! Your CT coil may be incorrectly installed and settings not correct. OR!! Your bonding is not correct Best would be to get a reputable knowledgeable person to check everything for you. Mention your area and maybe someone will reach out to offer assistance/advice.
