Battery integration

[sragas]

Are there any plans to integrate connected batteries?

[WillCodeForCats]

Yeah eventually. Right now I'm focusing on getting another integration released (my tekmar-482 integration) and once that's out I'll revisit this one. I'm planning to rewrite this integration since I'm finding how it was written is limiting to things I want to do with it, and he structure I used for the tekmar-482 integration is more flexible for me.

+1 from me!
Will also appreciate the battery integration to use your Integration! :-)

The rewrite-for-2.0 branch is at a point where it should detect batteries and create device entries for them, but there aren't any sensor entities yet.

[WillCodeForCats]

Anyone who has batteries please try the rewrite-for-2.0 branch and report if it detects your batteries or not. It will have some basic diagnostic sensors and show a device for each battery (up to 2 per inverter for up to 32 inverters).

Because battery registers are not technically officially supported by SolarEdge, auto-detection for batteries is disabled by default. To enabled battery detection, go to the device options and enable it.

Hi, I gave this a shot, I got devices for the inverter and the 2 meters, but no batteries. I have the newer SolarEdge Battery Banks BAT-10K1P, there are two of them.

I rolled back to the normal version for now since I wasn't sure if all of the entity names changed. I'll need to go edit a bunch of stuff to keep things working.

[WillCodeForCats]

Inverter entity names will be the same, meter entities will be slightly different since auto detect will scan every inverter for all 3 meters, which means it's possible to have more than 3 meters, so it names the meter entities with the inverter ID and the meter ID instead of fixed numbers. (I should say the inverter entity names are supposed to be unchanged but I haven't double checked them in old vs. new yet so there could be mistakes since this is still pre-pre release).

If you set debug logging it will log something for batteries. Basically the way auto detect works is it tries to read some basic info registers and if the read is OK then it adds the device. If the read returns any kind of error it ignores that location. The battery registers have been taken from an engineering pdf for the LG batteries where only 2 batteries per inverter were supported.

To enable debug logging:

logger:
    default: warning
    logs:
        custom_components.solaredge_modbus_multi: debug

And then in my logs the important lines are:

DEBUG (MainThread) [custom_components.solaredge_modbus_multi.hub] Inverter 1 battery 1: Exception Response(131, 3, IllegalAddress)
DEBUG (MainThread) [custom_components.solaredge_modbus_multi.hub] Inverter 1 battery 2: Exception Response(131, 3, IllegalAddress)

Which means there aren't any batteries at the battery register, in my case because I don't have any so the address doesn't exist. If you see those exceptions and you're not using the old LG batteries, then that means it's likely SolarEdge changed the battery registers or isn't using them.

I just pushed some updates to logging attributions so you'll need to re-download.

Hmm yep looks like the new ones aren't using the registers... That's very unfortunate...

I assume you're using the new "Energy Bank" battery system?

Edit: you already said that you are

[WillCodeForCats]

Well, I'll keep an eye out for any information about registers for the new Energy Bank system. Otherwise it's anyone's guess if they moved to different addresses or what.

[doonga]

Yep, no worries. Hopefully somewhere down the road. Thanks!

[WillCodeForCats]

It's still possible I got the registers wrong since I can't test any battery stuff myself, hopefully someone with the older battery system will give it a test to confirm it's an LG vs Energy Bank difference.
