Calling on Solar Techies
I have been thinking of going solar for some time and decided to pull the plug. My wants are a 400 to 500 watt system. I have four 12 volt batteries with 340ah. I am not planning on changing b...

After talking to tech support they said that the Charger Controller needs to be within 5 feet of the battery.
The contact was done by text so there was no explanation. It probably has to do with volt drop coming out of the battery side of the Charge Controller.
This brings up the distance between the panels and the Charge Controller. Since I have to put the Charger Controller close to the battery the distance from panel to Charge Controller will be approximately 35 feet. I am using 10ga wire for solar.
I would be interested on hearing from anyone that has installed their own system on a RV and what kind of distances from panel to Charge Controller were encountered. What size wire was used.
I have watched several DIY RV Solar installation videos and nobody discusses voltage drop between panels and Charge Controller.
I used a low voltage calculator and put in my perimeters and it's actually not great. But I am not sure those calculators are geared for low voltage that are present in solar systems.
I will have 5x100 watt panels wired Parallel Using a 40a PWM charge Controller.
Panel max power point 18.0v at 5.56 amps
Waiting to hear back from Tech support.
