We are considering a purchase of the Renogy DCC50s in our Camper Van. Our concern is that we cannot get a straight answer as to where the DCC50s should be located in relation to the batteries? We have a "garage" space underneath our bed platform in the very back of our van which is approx. 18" tall and approx. 24" wide by 24" deep where we will house two Lithium Ion Phosphate batteries (170ah each) and also our 2200 watt Inverter. The concern is in putting anything in this same compartment and risk overheating? So we are trying to ascertain the MINIMUM safe distance we need to have between each component, the Batteries, the Inverter and the DCC50s. Any would be very helpful.
