Since some moths my PowerRouter goes into ProtectionCharge at morning when the system wake up. This behaviour is quite strange because at evening it stops at the expected SOC (50% in my case) witout any error. There are now low voltage error or something similar.
I think that at morning, when it wake up, it do some check before start to charge the batteries and this cause an undervolte or something that put the system in “protection charge”.
I have also tried to lower the DOD but the problem is always the same.
Does anyone have similar problem ?
Here you can see my voltage, current and SOC graph.
