I use MPPT 75/15 charge controllers on my sailboat. They work great, however, when I run the motor and the alternator is also charging the batteries, the MPPTs get fooled into thinking that the batteries are charged and go into float mode way too early. They stay in float mode even after the engine is off.
Is there a way to avoid this or to restart the MPPT charge cycle?
I can make this happen by putting a blanked over the solar panels for a few minutes - but that is a difficult way to do it.
ps - what I'd really like to see is the MPPTs use the information/intelligence from the BMV-702 to manage the charge cycle :)
