I use three MultiPlus-II 48/3000 in grid-tie ESS setup.
I charge the batteries to 56V (absorption), it sits there for a while while batteries balance.
After a set time it enters Float at 55.40V.
When the multis change to Float they discharge at maximum inverter capacity for a few seconds, in my case over 6000W.
On a sunny day when my PV inverter is already exporting 15000W, an additional 6000W is a little too much.
The jump from absorption to float ignores grid-set-point, it ignores the ramp up/ramp down settings. It goes from 0 to MAX in a millisecond.
I cannot see this discharge in any of the widgets in vrm, but it is there, trust me. I see it in real-time if I look at vrm and I also see it in my other monitoring system. 18900W was exported at 11:27 (5/6-2021) exactly when multiplus went into float.
It is not a one-time thing. It happens everytime absorption changes to float.
I guess discharging to reach float is by design, but could it be done a little slower?
