Function:
1. Always keep the battery on fill voltage condition.
2. Prevent the battery from over-charging.
3. Prevent the battery from over-discharging.
4. Prevent the battery from reverse charging to solar panels during
nights.
5. Reverse Polarity Protection for Battery
6. Reverse Polarity Protection for Solar Panels
7. When the battery voltage is low, the controller will
automatically cut off the load from the system. If the voltage of
battery is back to normal and the load will restart working.
8. Thunder protection
9. According to the battery voltage grade, the controller can
automatically set charge-off voltage, the load-off voltage, the
load- restore voltage. (The parameter is default under 25℃
condition, locked by the CPU procedure, cannot adjust.)
10. The controller will automatically compensate the temperature of
the charging voltage according to the changes of ambient temperature.
Features:
【Automatic adaptation】
This solar controller automatically adapts to 12V/24V batteries, making it suitable for both lead-acid and lithium batteries.
【Innovative MPPT technology】
The controller adopts innovative MPPT technology, which detects the maximum charging current, resulting in a tracking efficiency of up to 99%.MPPT technology has many types, and our solar controller MPPT technology detects the maximum charging current instead of the automatic charging of boost type or solar panel voltage.
【Multiple protection features】
The solar controller is equipped with short-circuit protection, open-circuit protection, reverse protection, and overload protection to ensure the safety of the system.The charge controller should connect the battery first, then the solar panel, and finally the load!
【Efficient charging management】
With full 3-level PWM charging management, this solar controller is designed to improve system efficiency and extend battery life.
【Accurate display and lifetime technical support】
The industrial microcontroller offers 16AD sampling accuracy, and temperature charging current and discharge current are accurately and real-time displayed. In terms of after-sales service, Powlsojxd offers a 12-month warranty and lifetime technical support.
