This solar power manager is the ultimate base for this summer's solar power project!
The unit accepts 3x 18650 batteries (batteries not included) which can be recharged from either your connected solar panel or a type-C power adapter (5V, with PD quick charge support).
It's compatible with 6-24V solar panels with a DC-002 (3.5mm) connector, but also comes with a DC-002 terminal block adapter to wire your panel manually. The onboard MPPT (maximum power point tracker) SET switch allows you to tune charging efficiency by matching the voltage level to your input level.
The power manager outputs a regulated 5V 3A via the USB-A or USB-C output, which supports various protocols (PD/QC/FCP/PE/SFCP). The integrated LED indicators keep you informed on charging, polarity errors and other information.
Please read the Product Wiki before using.
