Brand new, never used solar panel installation kit by Zamp Solar. I believe all their products are made in the USA.
Includes Zamp ZS-30A MPPT digital controller (which sells for $140 alone on Amazon); rooftop combiner box for up to three panels, 8-gauge wiring from the roof box to controller and controller to batteries, and 40 amp circuit breaker.
Controller can be top-mounted or inset into a cabinet. See specs on Amazon: https://www.amazon.com/Zamp-solar-30.../dp/B00T36XBKI
$100 + shipping. Or pickup in the Philadelphia, Pa., area.
