It seems to be a fault code of some sort the unit works properly just want to know what the green led flashing intermittently means, it is set up as 24v but I’m using one deep cycle batt and one cranking batt the voltage across them is 12.60and 12.16 I wonder if the unit is picking this up

Cheers all

If you have Battery Life enabled, then the green LED flashes when in Float with Battery Life. Regular Float mode, the LED is solid green.

Hi Wkirby

The unit is set up not to be battery life mode ie the jump wire between pin 2 and 3 or pin 1 and 2 so the green light should stay solid

Cheers

Got my Bluetooth dongle and did an update on the charger and the green led is working as it should the previous version of software must have made the green led behave the way it was
