Safety Instructions: A) Make sure your battery has enough voltage for the waterproof solar charge controller to recognize the battery type before first installation only sufficient battery voltage can charge or activate the controller. That means it won't charge or activate when hooked to a dead or no-voltage battery. B) The battery cable should be as short as possible to minimize loss.
