Hi all,
My system: 7 x 440 PV. H1-3.7-E-G2. 1 x EP11. Work Mode Self Use.
I ran my ASHP to top up DHW at noon today (a short cycle from 33' back up to 43') Battery indicating 100% and lots of PV coming in.
When the water heating was complete the battery level was indicating 99%. Then a while later 98%. Subsequently, most PV energy was diverted to the grid -I was expecting the battery to be prioritised before exporting but that never happened. Three hours later at 5 pm there was 1.13kW PV incoming, of which 12w was to the battery (still at 98%) house 0.11kW and 1.01kW to the grid. Battery temperature was 18.5'. Prior to today I've always seen the battery go back to 100% pretty rapidly in sunshine, today it remained at 98%.
Any comments/observations/tips would be welcome. I've only been using the system for a week, please make allowances! Thanks.

Charge speed is quite restricted at the very high end of the SoC range. This is to protect the battery, since charging at high speed at this point in the battery range could cause battery degradation.

There's a post that discusses it here: viewtopic.php?p=4554#p4554

In my experience the battery will only charge if it drops below 97%. Otherwise it would be constantly trickle charging it which can't be too good for it.
