All things Sunsynk (Deye, Inge, etc...)

Zero faith in those cheap splitters so dug out the crimpers and rolled my own 'split' cable (fortunately I had two 'back to back' ethernet joiners handy as well). Heatshrink really finished it off nicely.

The first one failed 'cos I didn't leave enough slack so I think one of the CAN wires broke while I was manuevering it into place (tested fine but failed after fitment) but Version 2 works perfectly (well, the battery side anyway - my Solarassist cable hasn't arrived yet...)

Fail:

Success:

Having heard reports that people had issues when using a 'full' cable even though only '1-3' and '4-5' are used, I snipped off the unneeded wires in each connecter.

Tip for getting the wires on to the correct pins, use 'dummy' wires inserted from the top to block the the channels you don't need.

Lekker busy in there.

Maybe i missed this in an earlier post - any reason why your CT coils are inside the inverter? Is everything in your house on essentials?

Yes, everything is on the essential side.

I had an offline discussion with @Mike Hoxbig and @RonSwanson with respect to what to put on essentials / non-essentials and after some consideration, followed their advice to put everything on the essential side and then manage the high draw items (geyser, oven, pool pump) using the Sonoff/Redpole switches that I already have in place - I'm adding a Sonoff Loadshedder so that those high draw items can be switched off automatically when loadshedding hits irrespective of what I do with them via eWelink and HomeAssistant.

So, in the context of everything being on the essential side the CT coils may as well live in the inverter (which is where my installer prefers to put it as well).
 
I see Sonoff now have a switch that has a 'on delay" after power interruption. I see whether I can find it.
 

MINIR4 - SONOFF Official

SONOFF smallest WiFi smart switch ever, fits in various boxes, even the smallest European standard ones. Added 'Detach Relay' mode, which means the states of external switches and relay are separated, so operating the external switch button won't affect the relay state.

I see the delay appears to be measured in seconds. I suspect that could be changed relatively easily?
 
Getting the winter experience today in Cape Town - batteries just idling at 50% - really need to find my Pi3 so I can do the solar-assistant thing.

Ah ok - makes sense

The inverter has a setting to only return grid after a specified time. Set mine to 5min recently.

I think he was looking for switches that have a delay when the power comes on again. So some devices can be set to come on later.

What would solar assistant help you with in this case? I must have missed that.

Had to walk over to the inverter to change the work mode settings based on our loadshedding slots tonight.

I suppose I could leave it as is - but - you never know when Eskom is going to escalate, and I don't want to be stuck at 40-50% battery and we get hit with a four hour slot overnight.

You could use the standard sunsynk app for that... or am I missing something?

I have grid charge ticked from 15:00 - 18:00 and 18:00 - 21:30.

So if the battery isn't properly charged by late afternoon, there's some time to charge it before evening. If there's load shedding in that slot, then the next slot will charge it.

I find this doesn't require any fiddling. The only time I'll change something is to untick those 2 slots when load shedding stops. Which hasn't happened since September...

I have the same, but till 9pm. We have loadshedding till 8pm, and the battery is currently at 50%.


Virtually no charge today as the sun just covered home use.
 
Mines is one slot, 1am to 3am to charge to 60%. From 3pm to 1am battery soc is supposed to be 90% so if we use grid so be it.

With this settings covers most load shedding slots including the 4 hour slots we used to have from 8 pm 12am

Sun usually does the rest during the day to get battery to 100% with other workloads

I haven't changed inverter settings in weeks so that is saying something to me. Nice not to worry about it too much.
