3A 12V MPPT Solar Charge Controller Module CN3767 CN3722 Red with LED Indicator for 18V Panel System

3A 12V MPPT Solar Charge Controller Module CN3767 CN3722 Red with LED Indicator for 18V Panel System Description

Compact 3A MPPT Solar Charge Controller Module for 12V Systems This MPPT solar PV charger controller module is designed for small 12V battery systems and 18V solar panels. Compatible with CN3767 and CN3722 control IC variants, the module offers precise charging for 3S battery packs with a clear LED indicator and a durable plastic housing in red. Key benefits Improved charging efficiency: MPPT algorithm maximizes power harvest from an 18V PV panel for more effective charging compared to simple regulators. Reliable 3A charging: Suitable for small battery packs and lowpower applications that require steady current control. Clear status feedback: Builtin LED indicator shows operating and charging status for quick visual checks. Easy integration: Compact, plastic module form factor fits into small enclosures or DIY projects and simplifies wiring into existing 12V systems. Broad compatibility: Designed for 3S battery configurations at 12V nominal and matched to solar panels rated around 18V. What it does Manages the conversion from a solar panel to a 12V battery using an MPPT control algorithm for consistent charging at up to 3A. Works with 3S battery packs and is intended for systems where the solar panel open circuit voltage is near 18V. Uses CN3767 or CN3722 control IC behavior as the basis for MPPT and charging logic, with LED indication of status. Main specifications and attributes Charging current: 3A nominal System voltage: 12V nominal for 3S battery packs Solar panel compatibility: designed for panels around 18V Control ICs: CN3767 and CN3722 compatible Housing material: plastic, red color Indicator: LED status indicator for operation and charging Practical use scenarios Portable solar charger for small 12V battery packs in field equipment and hobby projects. Charge management for small offgrid lighting or sensor stations powered by an 18V solar panel. Trickle charging or maintenance charging for 3S battery packs used in RC models, small boats, or moto accessories. Notes for installers Confirm battery pack configuration is 3S 12V nominal before connecting. Match the solar panel open circuit voltage to the module recommendation near 18V. Observe proper polarity and wiring during installation. This module provides a compact, MPPTbased charging solution for small 12V systems using CN3767 or CN3722 control logic, delivering steady 3A charging and visible status through its LED indicator.
