8.4V Solar Battery Charger

　　Green Energy Pioneer for Off-Grid Scenarios

　　Designed specifically for 8.4V battery systems, the solar charger integrates efficient photovoltaic technology and intelligent charging management to provide clean and reliable power solutions for outdoor equipment, energy storage systems, and electricity in remote areas. Whether it is camping adventures, agricultural monitoring, or off-grid energy storage projects, our chargers can convert solar energy into stable electricity, helping global customers achieve low-carbon energy transformation.

　　Core advantages: solar energy empowerment, reshaping the charging experience

　　1. Efficient photovoltaic conversion, stable power supply around the clock

　　Equipped with polycrystalline silicon solar panels (optional 10W/20W/30W power), the conversion efficiency is as high as 22%, and it still maintains excellent performance in low-light environments

　　Integrated MPPT intelligent tracking technology, real-time optimization of solar panel output, charging efficiency increased by more than 30%

　　Support 12-24V solar input, compatible with photovoltaic modules of different specifications, and adapt to global lighting conditions

　　2. Fully compatible design, adaptable to multiple battery types

　　Support 8.4V lithium battery (Li-ion/LFP), nickel-metal hydride (Ni-MH), nickel-cadmium (Ni-Cd) battery pack charging

　　Automatically identify battery status, intelligently switch between constant current charging (3A max) and constant voltage floating charging modes, and extend battery life by 30%+

　　Built-in reverse connection protection, overcharge/over-discharge protection, and high temperature power-off protection to ensure a safe and worry-free charging process

　　3. Exclusive for off-grid scenarios, portable and durable choice

　　IP65 protection level: waterproof and dustproof design, suitable for outdoor harsh environments such as heavy rain, sand and dust

　　Lightweight body (only 320g), equipped with folding bracket, supports desktop placement, wall mounting or direct connection to solar panels
