Custom value for DischargeSlot1_SOC

[abrasive-blueberry]

Hi, I mentioned this elsewhere, and it's not really an issue, just a feature request.

It would be useful if users on the new inverter firmware were able to specify a custom value for DischargeSlot1_SOC. At the moment it is fixed at 15 meaning the battery will discharge all the way down to 15%. However one may not want to discharge this far for whatever reason, so the ability to set it to say 20 or 30% would be great.

There's already a "charge if SOC below" setting. Would it make sense to have the discharge SOC to be that value or 15%, whichever is highest?

I’m not sure it would.

For example you may want to discharge no more than 20% (as some battery manufacturers recommend) but not necessarily charge again immediately, due to the cost.

Okay. Will look at adding another option at some point.

I'd like to add a vote for this option. My inverter (Solis S5-EH1P5K-L) won't accept a setting for discharge SOC lower than 21%, so attempted discharges fail after 5 attempts, clocking up unnecessary EEPROM writes.
