Warranty Information

  • 1-year material warranty

1. What is the ground type of this charge controllers?
 

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.

2. Will this work with sealed lead-acid (SLA) batteries and lithium batteries?
 
Yes, it works. This solar charge controller supports LiFePO4, Gel, Flooded, AGM, and SLA (Sealed Lead-Acid) batteries.
3. Can I use this with solar panel only? No battery backup?
 

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).

4.Why do I need a solar charge controller? What are PWM charge controllers?
 

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.

5. Will this charge controller work for a 36V lead acid battery bank or 48V lithium battery?
 

No, it only supports 12V and 24V batteries.

6. Does this 30A PWM charge controller have a built-in 30A fuse for the rated 30A load output?
 

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.

7. How many watts can this 30 Amp charge controller handle?
 

The maximum input solar power for a 12V battery system is 450W while for a 24V system it's 900W.

8. When does the USB port have power? Only when the solar panel is outputting power or will it pull power from the battery?
 

The USB port pull power from the battery.
