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.
In this last month I have received the replacement for my PowerRouter due to the recall campaign for solar module problem. Now I have discovered 3 annoying issue:
1) (solved by Nedap support) I can’t see the consumption data of my old system on myPowerRouter. I can see all data exept data related to current sensor. This is my screenshot:
2) Now that is winter the DOD is limiteted to 75% and I can’t disable this protection system.
3) Detailed data of voltage, current etc. older than July 2013 are for me unavailable. The system have been installed in 2012 and I can see the data available in the dashboard (like solar yead) from 2012.
