The core value of a solar energy system lies in converting sunlight into a continuous and reliable energy source. However, issues such as fluctuating sunlight, unattended operation, and overcharging risks often become "hidden killers" affecting battery life and power supply stability. Whether it's a residential off-grid photovoltaic system, an outdoor solar energy storage station, or a RV photovoltaic power replenishment device, the intelligent charging and overcharge protection of a 12.8V battery directly determines energy utilization efficiency and equipment safety. We offer a custom-designed 12.8V solar system-specific intelligent overcharge protection charger—using AI intelligent algorithms to solve the pain points of photovoltaic charging and multiple overcharge protections to safeguard battery longevity, ensuring every ray of sunlight is converted into safe and reliable electricity.

　　Born for photovoltaics, designed for intelligent protection

　　AI intelligent power control maximizes photovoltaic efficiency: Equipped with next-generation MPPT maximum power point tracking technology, it tracks the peak output of solar panels in real time, improving charging efficiency by 10%-30%. Charging can start even on cloudy days or in low-light environments. The built-in FluxAI intelligent algorithm automatically adapts to different power solar panels (6-40V wide voltage input), eliminating the need for manual adjustments and achieving "sunlight-based charging and efficient conversion."

　　Triple overcharge protection ensures battery safety: Utilizing a triple overcharge protection mechanism of "precise voltage threshold control + temperature compensation + BMS linkage," it automatically cuts off power when charging to the standard 14.4V full charge voltage to prevent overcharging and bulging; intelligent temperature compensation of -20~40mV/℃ prevents overcharging in low-temperature environments and undercharging in high-temperature environments; and compatibility with the Battery Management System (BMS) allows for real-time battery status interaction, immediately cutting off the charging circuit in case of abnormalities, extending battery cycle life to over 5000 cycles.

　　12.8V precise adaptation for all photovoltaic devices: Designed specifically for 12.8V lithium iron phosphate/ternary lithium solar energy storage batteries, it perfectly adapts to mainstream capacities of 20-200Ah, compatible with residential photovoltaic power stations, outdoor solar energy storage systems, RV photovoltaic supplementary equipment, and solar power supply devices in remote areas, covering over 95% of 12.8V battery models in solar systems.

　　Smart APP Control for Worry-Free Remote Management: Supports Wi-Fi + Bluetooth dual-mode connection to a mobile APP, allowing real-time monitoring of charging power, battery voltage, remaining power, and temperature data; remotely sets charging modes (fast charging/energy saving/balanced charging), adjusts overcharge protection thresholds, and enables timed charging, ensuring precise power control even in unattended scenarios; real-time push notifications for abnormal conditions (overcharging, overheating, short circuit) to mitigate safety risks immediately.

　　Outdoor Weather-Resistant Design for Solar PV Scenarios: Meets IP65 dustproof and waterproof standards, completely resisting outdoor dust, rain splashes, and the dampness of the solar panel installation environment; operating temperature ranges from -20℃ to 60℃; the UV-resistant casing is suitable for long-term outdoor installation, withstanding extreme solar PV scenarios such as high-altitude sun exposure and desert high temperatures, ensuring stable and reliable long-term use.

　　Multi-mode power replenishment + safety certification, worry-free operation: Supports solar charging, AC fast charging, and vehicle charging modes, seamlessly switching to backup power when photovoltaic power is insufficient; CE, UL, and CCC certified, with built-in five protection systems for over-temperature, short circuit, reverse connection, overload, and undervoltage, complying with IEC 62368-1 photovoltaic equipment safety standards, ensuring greater peace of mind.

　　Suitable for diverse photovoltaic scenarios:

　　Home photovoltaic off-grid system: As a core component of a home photovoltaic power station, MPPT technology improves solar energy conversion efficiency, overcharge protection safeguards the energy storage battery, supporting the continuous operation of home appliances such as refrigerators, air conditioners, and lighting, creating a "zero electricity cost + high safety" green home energy ecosystem.

　　Outdoor solar energy storage power station: Suitable for outdoor operations, mountain cabins, farms, and other scenarios; low-light start-up function ensures charging even on cloudy or rainy days; remote monitoring via APP eliminates the need for on-site supervision, providing stable power for monitoring equipment, irrigation pumps, and communication terminals.

　　RV Solar Power Supply System: While driving, it charges via the vehicle's onboard interface; when parked, it stores energy independently using the RV's solar panels. Intelligent overcharge protection prevents charging anomalies caused by driving bumps. The app allows users to preset charging thresholds, ensuring a full charge upon arrival at a campsite.

　　Emergency Solar Backup Power: In the event of power grid failure after disasters such as earthquakes or typhoons, it can be quickly replenished with portable solar panels. Overcharge protection ensures long-term battery backup without damage, providing safe power support for emergency lighting, medical equipment, and communication tools.
