Solar Energy Manager (C)

This solar energy manager is the ultimate foundation for your solar energy project this summer!

The unit accepts 3x 18650 batteries (batteries not included) that can be charged from your connected solar panel or a C-type power adapter (with 5V, PD fast charging support).

It's compatible with 6-24V solar panels with a DC-002 (3.5mm) connector, but it comes with a DC-002 terminal block adapter to manually wire your panel if needed. The built-in MPPT (Maximum Power Point Tracking) SET switch allows you to adjust charging efficiency by matching the voltage level with your input.

The power manager provides a regulated 5V 3A output via USB-A or USB-C, supporting various protocols (PD/QC/FCP/PE/SFCP). Integrated LED indicators keep you informed about charging status, polarity errors, and other information.
