Get Ready for a New of Solar Charging: Enjoy smarter, high-power charging with the POWOXI M-Series High-Power ETFE Thin & Flexible Solar Battery Charger, featuring a fully potted and sealed IP67 waterproof independent MPPT charge controller built right in—no more searching for a separate controller, as we now offer this convenient 2-in-1 configuration to make your charging experience simple and effortless
Enhanced Independent MPPT Controller: POWOXI’s innovative IP67 potted technology ensures your solar trickle charger can handle any wet environment. It intelligently adapts to your battery’s temperature across different seasons, delivering the precise charging voltage needed. With a three-stage charging process (Bulk, Absorption, Float), it recognizes and applies the perfect voltage for every battery phase, providing more effective 12V battery charging, superior safety, extended battery life, and enhanced charging performance
Advanced P&O Incremental Conductance Algorithm: By repeatedly disturbing the voltage and testing different sunlight intensities to continuously adjust the charging voltage, the operating point of the solar system charging power gradually approaches the maximum power point, improving the charging efficiency and effectively increasing the charging efficiency by 36%*, ensuring superior performance even on cloudy days compared to non-MPPT chargers
ETFE Anti-solar refraction Material: ETFE’s exceptional light transmittance (up to 95%) significantly enhances solar cell efficiency by optimizing light delivery, making it perfect for a solar car battery charger and solar trickle charger for car battery 12V applications. Its high transparency is maintained long-term, while robust carbon-fluorine (C-F) bonds provide superior UV resistance, preventing embrittlement and degradation, and ensuring excellent tolerance to harsh temperatures and corrosion
Comprehensive Battery Protection: Select your battery type with the MODE button, 12V AGM GEL LiFePO4 and Lithium, This solar battery maintainer is compatible with all 12V lead-acid batteries (flooded, gel, AGM, SLA, VRLA, maintenance-free) for boats, cars, Marine, Trailer, RVs, powersports, campers, and deep cycle applications
Stronger & More Long-lasting: Experience effortless energy with the POWOXI M-Series Independent MPPT Controller Edition. Its 2-in-1 design and advanced POWOXI-M Series algorithm significantly boost solar charging efficiency. Enjoy worry-free charging with more comprehensive safety protections: over-charge, over-discharge, over-voltage, over-current, over-load, short circuit, polarity inversion, and over-temperature, all within a waterproof and spark-proof build that fully protects your battery
Intuitive Charging & Maintenance: The POWOXI 4-stage battery indicator provides at-a-glance monitoring of your battery’s charge level and charging progress. With clear 25%-50%-75%-100% indicators, you’ll know exactly where you stand. The next stage’s light will flash when charging, then remain solid once complete
This Solar Charger Offers Complete Hands-free Maintenance: the solar panel automatically stops charging when your battery is full and automatically resumes charging when needed, ensuring worry-free, continuous power
