Connecting portable panel through DC-DC
I have a 30 amp Renogy Dc-Dc in my trailer to charge my trailer batteries from the truck while traveling. Works great! This is direct wired from the truck battery to the trailer with 4 gauge wire and connected with an Anderson coupler. When at camp I’d like to charge my batteries in the trailer using an older Zamp portable solar panel with its own charge controller (think it’s a PWM). Can I connect the portable panel to the Dc-Dc and charge my trailer batteries. That connection is already available via the coupler to the Renogy. If I can should I remove the solar charge controller from the portable panel or leave it?
