Waterproof MPPT Solar Charge Controller 12V 24V 40A 3 Years Warranty

Features of  SR-ML4830

1. Advanced double-peak or multiple-peak tracking technology. When the panel has a shadow block or a part of the panel is damaged, I-V curve shows multiple peaks. The solar charge controller can still accurately track the maximum power point.
2. Built-in algorithm for maximum power tracking. This significantly raises energy utilization efficiency of photovoltaic systems, with charging efficiency 15% ~ 20% higher than traditional PWM solar charge controllers.
3. MPPT tracking efficiency can be as high as 99.9%.
4. Advanced digital power technology, with circuit energy conversion efficiency as high as 98%.
5. Supporting charging procedures of gel batteries, sealed batteries, open batteries, lithium batteries and other types of batteries.
6. LCD screen display function. The display enables users to view equipment operation data and status, and modify controller parameters at the same time.
7. Supporting standard Modbus protocol that meets communication needs on different occasions.
8. Built-in mechanism of over-temperature protection. When the temperature exceeds the preset value, the charging current falls linearly with temperature, therefore slowing down the rise of controller temperature and avoiding controller damage from high temperature.
9. Temperature compensation functions. Charging and discharging parameters are automatically adjusted, thereby extending battery service life.

Electronic protections:
• PV Over Current/power
