3007 Battery Firmware Update

Updated from 3005 to 3007 this morning and the system is currently performing what I expected to be its calibration run. Discharge down to zero went as expected but the charge back up to 100% seems to have changed. Instead of it being a forced charge at whatever battery charge rate you have set, it is operating in ECO mode and the charge rate is varying as the sun goes in and out and house usage goes up and down. Given that it is a cloudy day here it was going to take forever and I have manually changed to timed grid charge mode which is working as expected. This begs the question as to whether a software update recharge is no longer a forced recalibration charge to 100% but rather a low battery charge back up to 4%. Would be handy to have a definitive answer as it helps with timing the initiation of the update.

if it has changed and can calibrate by charging up more gently rather than forced import that is handy but would be good to know if the change is deliberate.

I think I’ll wait to see the notes in todays update and other users experience before I click the update button. I also want a decent solar day so I can time it to charge up from PV.

Does anyone know what this update does? Nothing on the knowledge base yet.

Not updating a working system until I know, lol.

locked I agree. If running the update in winter it could be days(weeks?) before the battery reaches 100% when operating in ECO mode! Perhaps the upper limit is no longer used for SOC calibration (as distinct from battery protection) and it is now all calculated from the battery empty reference point.

It is for fixing mis reported SOC on some batteries. Which is causing sudden drops, or rises in charge level. Affects multiple battery systems more, reading the comments. So looks to have some improvements in Cross pack battery balancing and SOC reporting.

Did check for the official release notes on it, but not published yet. So my reports are from peoples chatter on Fakebook

Woodstock yeah I had to manually force the recharge too. It dropped to “0%” immediately but wasn’t true 0 because it spent a while fully discharging and then recharged to 4% before I manually forced the full charge.

feidhlim Yes that's what mine did. Display dropped to 0% SOC immediately then spent some time discharging down to true 0.

wilfleek It's on the knowledge base now, although the date says 7/4/21 !

or does it...
