FAQ
1. What types of batteries and vehicles does this charger support?
This charger is designed for 12V systems only and supports LiFePO₄, AGM, SLA, GEL, FLA, EFB, and MF batteries. It’s ideal for cars, RVs, boats, motorcycles, campers, trailers, lawn mowers, and jet skis.
2. What is the 3-stage smart charging, and how does it protect my battery?
The controller automatically cycles through three stages: Bulk (fast charge), Absorption (steady top-off), and Maintenance (continuous pulse trickle). This prevents overcharging and optimizes long-term battery health.
3. Can this solar charger operate in freezing winters or extreme summer heat?
Yes. The panel features an IP68 waterproof rating, tempered glass, and a corrosion-resistant frame, ensuring stable power output across a temperature range of -10°C to 70°C.
4. Will this solar panel drain my battery at night or in zero sunlight?
No. The built-in controller includes a 6-in-1 protection system with a dedicated reverse current safeguard. This completely blocks power from flowing backward from the battery to the panel at night.
