Solar Controller to Battery

[fritzdfk]

I have two 50 watt panels and two Genasun 5 amp controllers. I am getting ready to install the system and was reading the instructions from Genasun where it states that the controller should be within 12" of the battery. I had not planned on this. I think the reason is that the Genasun controller has an internal temperature sensor so it has to be close the the battery. I had planned for the controllers to be within a few feet of the battery bank. It is a little hard for me to imagine that 8 amps from the panels is going to cause my batteries to overheat. I do have temp sensors connected for the alternator regulator and rarely used AC charger.

The temp sensor is Likly used for voltage compensation.

2’ vrs 8” isn’t going to change much. Just don’t put in a different room with a way different temp. Ie batteries in 60f bilge and controller in 150f engine room.
