[RE-wrenches] Fried Classic150?

[Dan Fink]

MPPT does need a minimum battery voltage to wake up and start charging, at
least 9 volts -- I once arrived at a remote site on a sunny day, the PV
input breaker had tripped, batteries were under 9v, no charging despite the
sunny weather until I woke the MPPT up with jumper cables from my truck
battery.
