I have a Renogy set up, 400 watt system. The charge controller has 6 (six) terminals
two for input form panels, two for output to batteries, and two to service a 12V load.
PROBLEM IS: no transfer of 12V to the 12V load terminals
There's 13V incoming 13V from batteries, and .01V at the 12V load terminals.
Is there a setting that I am missing?

Is this the 400W system with a MPPT Controller? Chances are you have to manually turn on the load to get 12V activated in the load terminals. -Renogy Team |

the load terminals have ~15 or so different settings, you'll need to find the dusk to dawn or various other setting you want or just use the battery's main terminals.

^^^ Great advice...^^^^
If you do use the terminals on the CC only use them for small loads like lights.... If you have a large draw like a fridge or something like that only go off of the batteries.... If you don't you will get error codes...

I purchased the 400W Premium Kit, which came with two 8ft tray cables to connect the charge controller to the batteries. Problem is, the solar panels will go on the roof of my skoolie and the batteries are in the compartment at the bottom of the bus. I think I need 20ft of cable rather than 8ft for each terminal. I see only 8ft and 16ft options in the Renogy store - is there a way to connect the 8ft and 16ft, or is there a preferred alternative?

You can splice them together and make sure that you shrink wrap them, they will be just fine......
Or go to Lowes or Home Depo and see if you can match up the wire and buy what you need...

Luis, it is best to keep tray cables (battery to controller) as short as possible. Panel to controller can be longer, one generally buys one wire with MC4 connectors on each end, ya cut it half and connect the mc4 to the panels and the bare end to the controller, you can easily extends these wires.

I was wondering, Couldn't you put a shut off or a fuse, I know he doesn't need one in-between the two wires to extend them without splicing them?
Just a thought...

An option could be to purchase a longer adapter kit www.renogy.com/solar-panel-to-charge-controller-adapter-kit/They come in 10-12AWG and 10-40feet. -Renogy Team |
