Anton asked this morning if those little boards are at risk from overcooking. Each one is rated to handle just under 2 amps. We doubled them up on each cell, figuring about 3.5 amps working capacity. The 400 watt solar array, converting through the Victron MPPT controller, is pumping at maximum about 6 amps total to the batteries. So with 4×3.5=14 amps of resistance capacity, I think we’ll be fine. Jeff said that in practice on his big cat in the tropics, yes the boards got warm when they kicked in, but never hot. We mounted them with double sided tape, which gives an air cushion under most of each board, and the whole cabinet is a good heat dissipation sink. Hopefully we’ve solved for Anton’s warnings.
Locals, let me know if you want to sail the boat next week. Throw some dates out and we’ll make some plans.
