Since yesterday’s daylight saving change, DESS drops ‘SoC target for currently active operation’ to 0% from 18:00 to 19:00 and again from 6:00 to 7:00.
This cannot be seen in VRM dashboard but can be seen using advanced graphs.
In the timeblock when the SoC target % reads zero, the MPII starts feeding the house loads from the battery instead of from the grid.
I strongly suspect this is not supposed to happen but it’s not fully clear to me how DESS works it fuzzy magic either. Can the dev team confirm this to be an actual issue or a feature somehow?
PS while this system runs ‘on autopilot’ most of the time, I have made some manual adjustments last week that are also reflected in the weekly graph. But the last 24 hours is pretty much just DESS and certainly those SoC target drops are ‘automatic’
System is MPII5 GX v3.60~53 beta (no solar but with additional boost chargers) on 44kWh batt running DESS Trade mode ‘Optimized with BatteryLife’ hence the slowly dropping minimum SoC over the last week.
Here’s what my chart looks like.
It seems “SOC target for currently active auto operation” reads 0% when (a) scheduled to supply loads from AC-coupled PV, and (b) when scheduled to supply loads from battery (matching your behavior).
There are a couple blips early this morning where the system unexpectedly supplied loads from the grid, rather than the battery (highlighted in the chart).
Our daylight savings change happened a few weeks back so I can’t comment on that piece (we had DESS disabled before then).
For troubleshooting DESS, I hold the advantage not running any solar, only trading dynamic prices.
Yes it’s definitely gone. Only significant system settings change was to lift all charge/discharge restrictions (timebased) in DESS/VRM.
I guess we need to wait for a dev to provide clarity whether this is a side effect of the incorporation of the ‘dess-hack’ into the 3.60~xx beta
@A-P I do wonder where these massive ‘drops’ to 0% ‘SoC target for currently active auto operation’ originate from.
There are quite a few of those in your graph.
