FAQ
1. What types of batteries are compatible with this 12V solar charger?
This smart 12V solar charger works with LiFePO4, Li-ion, AGM, SLA, GEL, FLD, EFB, and MF batteries. It's suitable for cars, RVs, boats, motorcycles, campers, lawn mowers, trailers, water pumps, and electric fences.
2. What is the purpose of the corner guards on this solar panel?
The integrated corner guards provide dedicated drop protection, shielding the tempered glass and aluminum frame from impact damage during transport, setup, or accidental drops in harsh outdoor environments.
3. What happens if I accidentally reverse the polarity or cause a short circuit?
The built-in controller features a 6-in-1 protection system. If you reverse the alligator clips or cross the wires, the safety circuit automatically cuts off power to prevent any damage to your battery or the charger.
4. How does the included 360° adjustable mount help with installation?
The 360° swivel mount allows you to adjust the angle of the solar panel flexibly. To maximize charging efficiency, use the included hardware kit to mount it in a location where it can face direct sunlight without shade.
