Hi,
I am installing an MPPT 75/15 in a caravan, with folding plug-in solar cells.
I am concerned that if the caravan is not used for 3 months then the 75/15 will drain the battery since it seems to consume 20mA when not in use. I have an isolator for the load side. Do I therefore need to install a separate isolator for the battery to prevent drain ?
Or can I just install a battery side isolator which will also act as an isolator for the load side (even when solar panels are plugged in).
Thanks
