Keep car, RV, boat, or off-grid battery banks topped up with this 20-W 12-V solar trickle charger and MPPT controller bundle. Monocrystalline silicon cells under a tempered glass face deliver up to 20-W in full sun, and an external MPPT controller pulls maximum power from the panel even in low light. An adjustable mount bracket and IP67 waterproof rating let the panel live outdoors year round on a dashboard, roof rack, or pole mount.
20-W Maximum Power: 20-W keeps a 12-V car or RV battery topped up during seasonal storage.
MPPT Charge Controller: An external MPPT controller pulls maximum power from the panel in low light and cloudy conditions.
Monocrystalline Silicon Cells: Mono-c silicon under tempered glass holds output efficiency longer than polycrystalline panels.
