## Questions & Answers

**Q: Will this work with lithium 12 volt?**
A: Sorry, this solar charger controller is not suitable for lithium batteries.

**Q: Will this work with a LiFeP04 battery?**
A: Sorry,the controller is suitable for 12V/24V lead-acid batteries and cannot charge lithium batteries.

**Q: I purchased the 20w 10a controller, controller seems to work on everything except load out put not getting power to the pos neg screws**
A: You must provide a 12 V rechargeable battery of some kind for there to be a load out voltage. The system is a battery charger and will charge your battery and maintain it to 13.2 V. USB chargers, at least my wireless charger is rated at one amp. USB voltage is 5 V. 5×1 is five watts per hour. So if you had two USB wireless chargers, as long as there was sufficient sunlight to charge your battery you could charge them for twice as long as the sun provided light. Anything more and your battery would start to degrade each day.

**Q: Why are wires from solar panel so short? I'm a girl trying to do this myself and wanted the panel on my shed roof but wires too short to reach control**
A: I am not the seller or the manufacturer. I purchased this kit. In my use case the wires were not too short. The controller was placed about two feet away from the panels in a weather protected case so I did not encounter this issue. Can I suggest buying extension cables and IP67 rated weather proof solar connectors as a solution?

This solar controller with solar panel works amazing it helps me out of a tough situation when my power went out and to help cut down on my electric bill in the lighting in my bedroom.This solar controller helped keep my battery is fully charged and maintained while regulating the electricity to my electronics!The insulation is very easy just need a small Phillips head screwdriver a spot to mount it and a battery connect to the ease of installation is as easy as 1 2 3This amount that controller on the wall mount your solar panel outside in a nice sunny w area and the rest will do its job!

### ⭐⭐⭐⭐⭐ Sensitive receiver, good quality mfgr. Works as promised.
*by O***0 on January 17, 2025*

The media could not be loaded. During my initial testing outside I couldn't get any output on the "load" connection. However, I must have been doing something wrong because today everything is working fine. I got a normal voltage and current output on both USB ports, a good charge voltage for the battery and over 10 volts/ 6 amps on the load. It should work fine on my e-bike for supplemental USB power and maintaining a12v battery for other peripherals.

### ⭐⭐⭐⭐ Worth the money
*by M***N on June 24, 2025*

Works well keeps my battery happy
