Technical FAQs 3

What are the advantages of a 3.3V 90ma stabilized output current?

The 3.3V 90mA stabilized output current ensures consistent and reliable energy provision for devices. MPPT algorithm is implemented to achieve maximum solar power conversion efficiency. Battery protection features such as overcharge and over-discharge prevention are present, contributing to an increased lifespan of the battery. Project 1.

How does a solar management module work?

This solar management module utilizes a constant voltage MPPT (Maximum Power Point Tracking) algorithm, which enables maximum solar energy conversion efficiency even in low light conditions. It can charge a 3.7V lithium battery via both solar panels or USB, supplying up to 70mA and 100mA charging current respectively.

How to install a solar cell?

Use heat shrink tube of 1/4" to protect the metallic part exposed of the cable previously cut. For installing the USB-A female cable, it's necessary to connect the red wire of this to the output of the voltage regulators while the black one to GND. For setting the solar cell, you can use double-sided foam-tape squares.
