Key features

• •【Smart MPPT Technology】This solar panel battery charger is crafted with SUN ENERGISE's unique smart MPPT technology. The innovative MPPT technology allows to deliver high tracking efficiency of up to 99% and peak conversion efficiency of 98%, improve 20%-30% utilization rate of solar panel system than other competitors.
• •【Improved 3-stages Charging】The smart 3-stages of charging algorithm (Bulk, Absorption, Float) is improved to better charge and maintain 12volt battery at a stable level for extended battery life. The charging will be cut off when battery has a full charge, and the charging will be resumed automatically when battery is not full, totally free maintenance.
• •【Full Protections】Prevent the battery from overcharge, over-voltage, discharge, and short circuit, reversed polarity protection, IP65 waterproof and spark-proof, the battery is fully protected.
• •【Compatible with Multiple Batteries】Widely used as a solar trickle charger and battery charger maintainer for multiple 12V DC batteries including Deep Cycle, Flooded, Maintenance-free, AGM, Seal Lead Acid and LiFePO4 lithium battery. A variety of scenarios for car, boat, RV, dump trailer, marine, camper, lawnmower, motorcycle, jet ski, tractors, trucks, ATV, trolling motor, etc.
• •【Robust & Durable】Made of A+ mono solar cells with efficiency up to 21%-30%, strong tempered glass and durable corrosion-resistant frame, which could withstand high temperature and UV irradiation, well built for years. This 12V solar battery maintaner can withstand all weather conditions such as sandstorm, strong wind, thunderstorm, blizzard, hail, up to 2400Pa wind pressure and 5400Pa snow load.
• •【Easy to Use】This solar trickle battery charger starts to charge immediately when battery is registered, all three cables connections are plug and play. You can clearly know the charging status of the battery and solar panel through the indicator light.
