W@P's Solar System

Ok, so my one Hubble is back from repairs. Cell no 13 was faulty and they replaced it. Also updated the firmware. My Riot is also back. Repair stated that they soldered a connection for the unit to connect to the internet. Wtf that ever means?

Took a month for my repairs to be done and have the battery back with me. Now to mount it again.

What did you end up implementing to prevent this?

Usually smart switches/timers so that certain devices don't turn on at the same time

Yeah pretty much. Using Solar Assistant to monitor the inverter and loads. Will switch off geysers if load gets too high, then pool pump. If all of those are off and the load is still close to the limit I get a Telegram notification and I play a TTS notification on the speaker in the kitchen to warn people in the house. This is so that they don't switch on more appliances.

During loadshedding I also monitor the load, but the limit for the warnings is lower. I also have the geysers and pool pump off during loadshedding by default. Then I also monitor the current power draw and estimate if the batteries will last till the end of the load shedding slot and give a warning if too much power is being used.

This system keeps growing over time, and I add to it when I notice something that doesn't work well or can be improved. Also still need to get more devices on a smart switch, so I can turn off the dishwasher, deep freezer etc as well. And the aircons.

Very cool! Which smart switches do you use? Is everything on the “essential” side?

I have someone coming to do a quote on Tuesday so doing all the reading I can now. I’ll probably only be able to do a 8KVA inverter for now.

Whole house and flat is on essentials. Might change the flat later on depending on load when there are people living there. Geysers are controlled with CBI Astutes, pool pump is on a Sonoff POWR2. Planning more CBI plugs for the dishwasher. Haven't found a solution for the big aircons, it doesn't look like any smart switches can handle that load so will probably install a decent relay and control that with a Sonoff basic or similar. I should also change the geyers to 2kW elements at some stage to reduce peak loads.

All of this is controlled through Home Assistant.

Thanks for all the information

Are you on an 8KVA inverter?

Are you able to control the switches with only the solar assistant data going into home assistant?

What’s your battery setup with regards to brand / capacity? I read the newer Hubble batteries don’t support solar assistant so just trying to find out which brands integration are working well.

SA and HomeAssistant will be able to give you the data to control the switches etc. Usually you only need SA connected to the inverter - the battery data is a bonus / additional - you don't need the SA >battery cables

Bliksem very nice setup you got going there. I live alone so if I overload the system it's my own fault. Also, the whole house and 2 geysers are on the essential side. The last couple of 4 hour LS slots drained my remaining 1 battery that I have atm to shut down a few times. Just couldn't make it for the 4 hours. The repaired battery will be installed tomorrow.

Yeah, Solar Assistant gives you all the data available in the inverter. I have an 8kW Sunsynk and 2x Hubble AM-2's. I use Node Red to control all of this data but most people do it using automations directly in HA.

I have even had my wife ignore the TTS messages until the batteries were drained and the inverter switched off because the sun is shining. Had 6kW load on at 7am during load shedding. So there is always something to improve, and why I now monitor the battery load during load shedding to check if it will last till after load shedding.

I can imagine losing half the system makes it very difficult to adapt again. Once you have to actually manage the battery charge you realise how much power you actually consume, the 5 or 10 kWh in the batteries are not a lot.
 
Ok so i have an issue here. Batteries SOC shows 100% bat they are drained according to the voltage and status indicator lights on the batteries.

I don't know wtf to check. Pins are correct for master and slave battery. Battery config is Lithium with voltages set to 53.6 with 200ah capacity, 40a charge capacity, and 100ah discharge.

Check battery comms. What does your LiBMS screen say?
 
Adjust your RIOT's webpage refresh to Realtime - last 10 minutes, and 5 second intervals. Scroll to the bottom right hand corner of the Home System V5 interface, you will see the BMS status there. Here is mine, just finished charging:

You can clearly see with mine that all 3 batteries are full and the BMS is balancing.

What does yours say?

Looks like you have an issue with P1

I now have it fairly stable, except for P3 which is bleeding a bit:

and it will bring up this

Adjust "Last Day" to something like 15-30m, and grouping interval to 10s.

Take a look at the balancing activity, you will probably see P1 taking on little bits of current every now and then.

Here is mine for comparison, P3 bleeding every now and then:
