I have a MPPT 30/100 connected to a pair of 6V Trojan GC-2 lead acid batteries in series. I need the correct settings for the rotary switch. The controller is connected to 4X100W solar cells which are connected as two pairs in series and then those paralleled. Right now the controller only shows a flashing float light. I get 35V checking with a DVM on the cell outputs to the controller
Setting number 4 is probably the closest match for Trojan T-105 GC2, but it's not an exact match.
Your battery calls for:
Bulk - 14.82V Float - 13.5V and Eq - 16.2V
Setting 4 gives you:
Bulk - 14.9V Float - 13.8V and Eq - 16.7V
If you want to set up the controller for an exact match then you'll need to use the Victronconnect software or App.
I'm not sure why you have a flashing float LED, that means controller over temperature.
Are you sure that the PV is connected with the correct polarity? Reverse PV polarity will make the controller hot.
Essentially they're flooded Pb's. I use a Century clone. And it seems Trojan have changed from 14.4/13.2, which they once recommended.
Frankly, the stocko Victron Pb settings on my kit (14.4/13.8) I consider excellent, and see no need to change. You may not have the portal graphs to look at, but that stock algorithm does some clever things and is special to me. If I had to improve upon it, nahh I couldn't.
