50A MPPT Solar Controller
50A MPPT Solar Controller
Description:
The SRNE 50A MPPT Solar Charger delivers high-efficiency solar charging for 12V and 24V battery systems. Advanced MPPT (Maximum Power Point Tracking) technology maximises solar output in real time, providing up to 30% higher charging efficiency than PWM controllers. Ideal for off-grid, 4WD, caravan, and marine applications, the SRNE 50A ensures stable charging, improved battery protection, and longer system lifespan in variable light conditions.
Specifications:
*MPPT tracking efficiency can be as high as 99.9%.
*Advanced digital power technology, with circuit energy conversion efficiency as high as 98%
*Supporting charging procedures of gel batteries, sealed batteries, open batteries, lithium batteries and other types of batteries.
*Supporting the start of capacitive load instantaneous large current.
*Supporting automatic identification of battery voltage.
*LED indicator of malfunction, buzzer alarm, and liquid crystal display of abnormal information.
*Supporting historical data storage for up to 5 years.
*Supporting standard Modbus protocol that meets communication needs on different occasions.
*Built-in mechanism of over-temperature protection.
*External battery voltage sampling function.
*Temperature compensation functions.
*TVS lightning protection
