· Install the controller as close to the batteries as possible with enough of a gap for heat ventilation. This reduces current loss. It also helps with controllers that have an internal temperature sensor to have an accurate estimate of battery temp for proper charging.
· Don’t install a charge controller above the batteries. You don’t want any off-gassing to disturb the controller’s electronics.
· Make sure to fuse the (+) wire close to the battery so any system short doesn’t start a fire.
· If the charge controller has an external ground (chassis ground) terminal on it, you should run a separate wire from this directly to the vehicle chassis. This subject gets really complicated to understand as a vehicle is different from most other types of electrical systems. Follow your instruction manual, which will most likely say to do it this way. The basic reasoning for this is that if there is an internal fault (broken bit inside the controller) then electricity still has a path back to the battery to properly pop the fuse.
