As seen below the charging power of the ESS drops at exactly 90% SOC to 1/3 of its nominal power. This is documented nowhere and I would like to continue 3KW charging at least to 5% more.
I checked VEConfigure as well as all the settings inside the Cerbo for the Multiplus.
My first guess was that 90% incidentally 51.5V and that the limit for absorption. That is not the case. The switch from absortion to float seems to be entirely unrelated to this 90% limit. The pylontech battery also supports more charge (big ESS bank of 6x US 5000). The charge current limit is also 60Amps under device limits of the pylontech bank.
So my question is where does this 90% charge power limit come from and how can I change it?
(The limit neither comes from VE Configure Charge curve, nor pylontech charge current limit)
