Cypress’ MPPT Solar Charge Controller is a battery charger and load controller for standalone PV (photovoltaic) systems. This controller features a smart tracking algorithm that maximizes energy harvest from solar panels. The controller also prevents over charge or deep discharge. It provides automatic load control for the external load connected to the controller board.

This optimized battery charging process increases battery life, minimizes battery maintenance, and improves system performance.

Maximum power point tracking, referred to as MPPT, is an electronic system that operates the photovoltaic modules to produce maximum power. MPPT varies the electrical operating point of the modules and enables them to deliver maximum available power. The additional power harvested increases the current available for battery charging. MPPT can be used in conjunction with a mechanical tracking system, but the two systems are completely different.
