Are the diagrams for the camper vans 12v and 24v friendly in terms of wire gauge??

As of writing this reply, all diagrams on this page are for 12v battery banks.

Hi Nate, I'm looking at the Victron MPPT 150/35 you recommend on Amazon for $295. I'm seeing a Renogy MPPT 40a with bluetooth module for $140. Is the Victron worth the extra money in your opinion? If so, why?

Hi, I thinking about building a light weight foldable, portable system with 10 x 160 watt flexible solar panels tied together, 2 series x 5 parallel. But use far less battery then what you show in the above examples for the following reason. When the cells are operating in the day is when I will need the most power (i.e. appliances, computer, power tools etc.) I was thinking of 2x100AH battle LI batteries for a total 200AH. If I average 1000 watts of the solar throughout the day, I should have 600 watts left to charge the batteries. Then use the batteries at night. Basically, sufficient solar wattage for both day electrical use and charging batteries from previous night use. Is there a reason why your above examples have very little solar wattage (it looks just barely sufficient to only charge the batteries)?

Hi Nate, I downloaded your pdf for 200Ah/400W wiring. I see you are using a RV panel for the AC and DC. I am wiring a skoolie and wanted to go with a DC fuse block and an AC panel. How would that affect the hook up at the distributor? Is there enough poles to do that on the Lynx? I was also trying to figure out what was between the battery negative cable and the lynx (connecting the battery monitor), is that a fuse or a component that comes with the Lynx and monitor?
