Zamp ZS-30A Solar Charge Controller

Description

Zamp ZS-30A PWM Solar Charge Controller
This 30 amp/500w controller has been in use for the past 5 years on our camper--it was part of the original factory solar setup. I recently upgraded the solar system on the camper, so am selling this. There is a cosmetic scuff at the lower right, visible in the picture, where the aluminum paint has been rubbed away and the black plastic shows through. I guarantee it to be in good working condition. Very simple setup--four screw terminals, two for battery and two for solar panels.
US buyers only, please.
