I have two 150/70 mppt’s. One is in “float”, while the other has been in “bulk” for days. One the cerbo screen this mppt (the one in bulk) is showing that it is in “off” state. My battery charge is at 100%. I don’t turn shore power off much. But when I do and the batteries need to recharge it seems to take forever (all daylight) to bring them back to 100% regardless of how much charge was used. I am really at a loss. Can anyone help?
