Product overview A solar charge controller designed for photovoltaic systems that combines efficiency maximum power point tracking and an integrated thermal management mechanism. It optimizes energy harvest while reducing temperature rise in the controller during heavy use. Key benefits Higher energy yield: Builtin MPPT algorithm achieves up to 99 percent tracking efficiency, improving overall PV system energy utilization by about 25 percent compared with PWM charging methods. Reduced temperature rise: An over temperature mechanism monitors device temperature and, when the set threshold is exceeded, reduces charging current linearly as temperature increases. This behavior reduces controller temperature rise and helps limit thermal stress on the electronics. Stable charging performance: The controller adjusts charging current according to temperature and solar input, maintaining effective charging under varying conditions and improving system responsiveness to changing irradiance. Main features and functions Maximum power point tracking with up to 99 percent tracking efficiency. Over temperature protection that linearly reduces charging current above the device setpoint to control temperature rise. Charging regulation tailored for photovoltaic arrays and battery systems to improve energy conversion compared with PWM controllers. Compatibility and applications Designed for use with photovoltaic arrays and battery charging systems in on grid and off grid installations. Suitable replacement or upgrade for systems currently using PWM controllers to increase energy harvest. Typical use scenarios: Residential rooftop solar systems where higher energy yield is desired during variable sun conditions. Off grid cabins and remote power systems that benefit from improved solartobattery conversion. Mobile installations such as RVs and boats that require reliable charging and temperatureresponsive current control. Performance considerations MPPT efficiency figure applies to the tracking algorithm under typical operating conditions and directly affects harvested energy versus PWM charging. The over temperature mechanism reduces charging current progressively above the configured temperature threshold to limit component temperature rise. This reduces thermal load but will also reduce charging current during temperature events. Installation and design notes Intended for integration into photovoltaic charge controller installations. Check system voltage and current ratings to confirm compatibility before installation. Configure temperature setpoints and charging parameters according to system battery type and site requirements to balance charging performance and thermal management.
