HQST 40A 12/24V MPPT Solar Charge Controller, Compatible with Sealed, Gel, Flooded, Gel, Lithium, User Defined Batteries

Make sure this fitsby entering your model number.
Solar panel short circuit protection, battery open circuit protection and TVS lightening protection etc.
A built-in maximum power point tracking (MPPT) algorithm can significantly increase energy utilization efficiency of the photovoltaic system, which is about 15% to 20% higher than traditional PWM charging. It provides an active charging voltage regulation feature. At battery open circuit or lithium battery BMS overcharge protection, the controller battery terminal will output the rated charging voltage value.
MPPT tracking efficiency is up to 99.9%. Due to an advanced digital power technology, the circuit energy conversion efficiency is as high as 98%.
Available in multiple battery types and support charging procedures of various types of batteries such as lithium battery, colloidal battery, sealed battery, vented battery, lithium battery, etc.
PowerCatcher maximum power point tracking technology allows the controller to track the maximum power point of solar panels even in a complex environment. Compared with the traditional MPPT tracking technology, it boasts faster response speed and higher tracking efficiency.
