Sok 206 configuration a must to connect to 24 volt? Magnum MM1524 AE won't charge?.

[Ravenhostel]

Hi, I'm new and trying to figure out why my Magnum charger won't charge. The batteries charge fine with solar but the charger does not seem to do anything. There is a green light on the charger/inferter what is supposed to flash every 4 seconds and it does. But the voltage on batteries only goes up to 27 volts max that is including solar power coming in. So I wonder if I turn on the generator if it really switches to charging? The Magnum has factory settings on lead acid batteries?! I don't have the remote so can't change anything. Also I'm not sure if there is a licium setting? There is an option for AGM. So, do I have to configure the batteries? Could that be the problem?
Any help is greatly appreciated since I live of grid fly in only and need to get that sorted before winter.
Greetings
