Hi,
I have 3 Victron MPPT’s (1 75/15 and 2 100/30) charging a LiFePO4 12v battery on my sailboat. There are occasions where I want to be able to shut the solar off completely; example, for maintenance, or during storage. I have a breaker switch between the MPPT’s and the battery, so this could happen manually. Or, if I go over current or over/under voltage, the battery could be cut off by my BMS or by my LVC or HVC’s. It’s not the “normal” case, but it could happen and it would leave a situation where the panels are still active and connected to the MPPT but there is no battery connection.
So, my question is, is this ok for the MPPT’s, i.e. you still have solar input but no battery. I’d just like to make sure that I won’t damage the devices. If it is not OK, then how would I protect the MPPT?
Thanks
Chris
