Solar PV Monitoring/Automation Thread

I'll have a root about later and start making those changes. Thanks for the heads up.

Thanks for the offer, I've ordered a Dell Wsye (second hand) that already has the application installed so am hoping to set it up trial and error wise, I have the Solis account set up and have a lot of Tuya and eWe smart devices dotted around the house and garden.

All I need now is the kit installed (middle of May).

Reading bits on the website I see you can integrate the Tuya devices relatively easily, I assume the panels, inverter and batteries will be handy enough?

Thanks

Ebay, there are a few of these for sale, but this one caught my eye as it seems to have HA installed already. I have an old Rasberry Pi that I use for media streaming but not sure it would be upto running HA as well, plus I didn't want to start messing with it in case I messed up all the music on it.

Thanks

And for anyone else who has access to an old Thin-Client PC (I've a Lenovo M73 Tiny ) loaded with Linux-Mint. On this, I have configured SSH and RDP (DON'T set it to Auto logon), and it runs Docker with Portainer, Home Assistant, Node-Red and several others. It's in the shed with the inverter, no keyboard nor monitor. Plenty of USB ports if needed.

Super easy to restart any program without restarting the whole PC

If when you get it the BIOS password is still set then try "Fireport" and that should get you in.

Any ideas why the data on the Solis app does not correspond with that downloaded from SolisCloud?

The numbers provided in the Excel export are stored as text and when converted to numbers and summed, do not tally up to what Solis says is the monthly yield, e.g. 578kWh instead of 570kWh and 93kWh instead of 90.2kWh (the higher numbers being what is reported by the app and the lower number being that calculated from the exported data).

Fine tuning:

Guys, just trying to get my head round the set up of the system once installed, (hopefully the installers will have the interest and knowledge) but better that I understand as well.

What I’m struggling with is how should the inverter be set up, ideally I only want it to charge the batteries from the grid during the EV window (Energia 2-6), but I assume that there is a minimum level that the battery should be allowed to discharge to, is that what Solis call Force charge SOC?

So if the grid charge window is 2-6am and FCSOC was 10% does this mean that the battery will only charge from the grid during those hours and outside of this window once depleted to 10% (1.04KW-10.4KW battery set up) the batteries would “sit” and just wait for the panels to begin charging if/when load (house) demand is met and not try and charge from the grid until 2am next day, (providing the inverter is set for “Self-Use mode” Solis S6-EH1P5K-L-EU)?

Also what sort of values should be used for charge and discharge of the batteries, I understand the charge current should be kept as low as possible when charging say (10-50Amp) but have read/watched various bits on the Solis inverters which say discharge should be left at 0Amp (other wise batteries will always discharge to the FCSOC level?)

Thanks

removing a basically insignificant sensor as the api counter in the

Jasus!

Looking for a little help here. I have a granny charger that I can turn on and off with home assistant using a shelly 1 PM. I would like to create an automation so when I turn it on manually it automatically turns off after 2 hours.

I have another automation set up where if the grid import is over 500 watts for 10 seconds, the charger switches off. Is it possible to have it switch back on when import normalises?

Hilarious! I was only considering the same here when we were barrelling down the M50 and I heard "...I think I left the straightener on".

Solved!

Hey guys I need a hand with creating some automation for HA about dumping to grid and I am guessing many already have it so pls share it if you don't mind.

I am looking for something like once it's 8pm (or any time) it needs to look at current soc and be able to set the grid export power so that the battery gets to 10% at 2am.

How are yous doing it?

Hi @SD_DRACULA,

I run this at 11:15 at night,

1) Disable Zappi

2) depending on the remaining capacity set the discharge rate to 55amp & time to calculated length, ( above 70 is 23:15 to 02:00; above 60 is 23:30 to 02:00; above 40 is 01:00 to 02:00 else no discharge )

3) Sleep until 2:00 and turn Zappi back on

I actually have a calculation for battery time left (at current discharge power) which gives me something like 2hr 30min, or just the integer of seconds so I need to somehow calculate back from 2am to current time and what power I need to be discharging at but not too sure how to code that.

I think I might have something, in theory if I export 5kwh for 6 hours that's it empty at 2am.

And this should calculate the export needed based on SOC (5000w export at 100% SOC):

Might need to cut 200-300 watts from it since setting the export to 5kw usually drains 5.2 or 5.3kw, but in theory should be good
