Negative ground controller. A negative-ground controller is more common and can fit most vehicle systems. When in use, you can connect a cable to the negative terminal of any device in the wiring system.
No, you can't. The controller's purpose is to safely control the charging voltage and amperage delivered to the storage battery bank. The controller is powered by the battery, not the solar panel(s).
A solar charge controller is a regulator for your solar battery that prevents it from overcharging. Batteries are rated for voltage capacity, and exceeding that voltage can lead to permanent battery damage and loss of functionality over time. Solar charge controllers act as a gate to your battery storage system, making sure damage doesn’t occur from overloading it.
PWM (Pulse Width Modulation) Charge Controllers work by slowly reducing the amount of power going into your battery as it approaches capacity. When your battery is full, PWM controllers maintain a state of "trickle", which means they supply a tiny amount of power constantly to keep the battery topped off. PWM controllers are more suited for small DIY solar systems with a couple of low voltage panels and a small battery.
No, it only supports 12V and 24V batteries.
No, it doesn't. We recommend adding an external fuse between the charge controller and battery bank for safe system operation. To determine the fuse size needed between the charge controller and battery bank, you can match the amperage rating on the charge controller. For instance, if you're going to install this 30A charge controller, we recommend using a 30A fuse.
The maximum input solar power for a 12V battery system is 450W while for a 24V system it's 900W.
