CN3795 MPPT Solar Photovoltaic Charging Module 2A This MPPT charging module enables charging of rechargeable lithium battery packs from a solar panel or other photovoltaic sources. It uses maximum power point tracking to optimize energy conversion and improve charging efficiency. Key benefits - Efficient MPPT energy conversion that increases charging speed and reduces wasted energy. - Simple two wire connection: connect the solar panel to the input side and the battery to the output side to begin charging. - 2A maximum charging current suitable for small to medium lithium battery packs. - Compact, modular design for easy integration into off grid, mobile, or remote power setups. - Compatible with common rechargeable lithium chemistries such as Li ion and LiFePO4. - CN3795 MPPT control provides reliable operation for solar charging. What you get and how it works - The module takes energy from the solar panel and uses MPPT to find the optimal operating point, then charges the lithium battery on the output. - It is designed to be integrated into simple solar charging setups without needing additional complex circuitry. Compatibility and use notes - Works with typical solar panels used in off grid or mobile applications. - Best results are achieved when used with lithium battery packs within the 2A charging capability of the module. Use scenarios - Off grid cabin or RV power system: connect a solar panel to the input and a Li ion or LiFePO4 battery pack to the output to maintain a ready charge for essential devices. - Remote monitoring or sensor deployments: keep a lithium battery charged to ensure continuous operation in locations without grid power. - Marine or caravan installations: maintain a charged lithium battery while traveling or at anchor, reducing the need for shore power.
