Progressive Dynamics charger/converter for 2 Trojan T-105’s

Choosing MPPT controller is the very last stage, after deciding on battery bank and array size - how many of those 24V panels and how many watts each.

Change the light bulbs, meanwhile. I'm not kidding. Mex is right, for boondocker this is not optional.

My controller has max 100V input, 2 panels in series, 64V total input.

In "Members Installs" you will see designs with rooftop junction box - this aspect of "tying it in" may be necessary with 12V panels and PWM controller but can be avoided with 24V panels and MPPT.
