Charge controller for Tecmate TM-522D solar charger

The Tecmate TM-522D charge controller is a fully integrated charger with a multi-step program for protecting, charging and maintaining the battery. The LED display provides information on charging progress.

A solar panel will supply electricity as it absorbs sunlight. A charge controller is required to regulate the voltage so that the battery receives the correct charge voltage. The charge controller automatically provides a safe charging experience 24/7, it cannot supply electricity until it is correctly connected to the battery. Once connected and charging, no supervision is required.
