The 5A MPPT Solar Panel Regulator Controller is a smart charging and protection board for lithium batteries (Li-ion 18650), with a built-in MPPT algorithm for optimal utilization of solar energy.

It supports input from a solar panel 6–24 V, charging current up to 5 A, and features a 5 V USB output for powering small devices.

The LED display shows in real time the input voltage, battery voltage, and charging current, while the built-in circuit protects against overcharging, overdischarging, overcurrent, and short circuit.

Ideal for DIY solar projects, portable batteries, lighting systems, power banks, or small standalone energy circuits, offering efficient charging and safe operation in a compact form.
