Is it ok to leave my MPPT connected to the battery for extended periods of time without any solar input?
asked
MPPT connected to battery with no solar input
Will it damage the mppt? No.
Will you battery have a small parasite load? Yes.
So leaving it connected depends on length of time will drain the battery.
If lifepo4 it might go Into a sleep mode (to prevent a deep discharge like that).
If lead based will possibly be damaged (but then long periods without maintenance the damage will still happen due to self discharge.)
Thank you.
