hi my 250/100 is doing weird things,, it normally does 2.5 hrs in bulk, then 2.0 hrs in bulk . then float,, but now after a update sometimes it will go straight from bulk to float, then other times like now it says its buy the green light its in float but the history says its not in float? how weird,,, a new thing i completely disconnected this for 1 hr, no solar/no battery, then connected the batt wires , and got the right batt volts,, but it says the solar has 48 volts coming in, but no watts/dude there's no solar connected to the charge controller, i think you should have no volts if there's no solar connected? right
