I have solar tracking on and priority set to battery 100% - meaning I want my Tesla ev to charge only if there’s excess solar after charging my powerwalls. However, when the powerwalls discharge to 0 overnight, the next morning Charge HQ doesn’t seem to recognize the powerwalls and turn the ev charging on (obviously before fully charging the powerwalls) - this keeps my powerwalls at 0 the whole day utilizing the "excess solar’ for ev charging. This defeats the whole purpose for me using this app. Current workaround is to manually set the backup reserve in powerwalls to 5% - then the Charge HQ app detects the powerwalls and everything works as expected. It’ll be good to resolve this bug where the app detects the powerwalls despite 0 SoC on powerwalls and allow me to use them at 0% backup on powerwalls.
This is a known issue which will be fixed at some point. Is it possible to set the backup reserve slightly above 0%? I don’t have a Powerwall handy to check.
Yes, that’s the current workaround. The minimum backup we can set is 5%. So for a 3 powerwall system it would be ~2kWh capacity “wasted” per day. Especially in California where each kWh costs >$0.6, cost for the 5% backup adds up. Great app, btw!
