CN3795 MPPT Solar Charging Controller Module for Lithium Batteries Overview The CN3795 is a compact MPPT solar charging controller module designed to extract more usable power from small photovoltaic panels and deliver it to rechargeable lithium batteries. Its maximum power point tracking function adapts to changing light conditions so the panel operates closer to its output, improving energy transfer compared with a simple direct connection. Key benefits Maximizes solar panel output: MPPT tracking helps the panel deliver higher usable power under variable light. Simple to use: connect the solar panel to the input terminals and the lithium battery to the output terminals for straightforward charging. Compact and easy to integrate: small PCB module suitable for DIY projects and compact installations. Main features Model: CN3795 MPPT solar charging controller module Charging capability: up to 2A charging current Function: maximum power point tracking for photovoltaic sources to improve energy conversion under varying light intensity Intended battery type: rechargeable lithium batteries Form factor: PCB module, size approximately 3 x 5 cm Compatibility and applications Works with small solar panels and common rechargeable lithium battery packs for lowpower systems. Ideal for projects that need more efficient solar charging than a direct panel to battery connection. Example use scenarios Off grid sensor or IoT node: keep a small lithium battery charged from a rooftop or rooftop sensor solar panel for autonomous operation. Portable lighting or emergency power: charge a lithium battery for LED lighting or small portable devices during daytime for use at night. DIY solar projects and prototypes: integrate the module into hobby and experimental setups that require compact MPPT charging.
