Description
20A – 12/24V
The PR of charge controller is the latest charging technologies, result in optimal battery maintenance and control of the module output of up to 900 WP which can be connected it. A large display informs the user about all operating modes with the aid of symbols. Data such as voltage, current and state of charge can also be displayed digitally as figures on the display. In addition, the controller has an energy meter which can be reset by the user.
Features:
- Hybrid controller
- Automatic detection of voltage
- PWM control
- Multistage charging technology
- Load disconnection depending on SOC
- Automatic load reconnection
- Temperature compensation
- Common positive grounding or negative grounding on one terminal
- Integrated self test
- Night light function
- Monthly maintenance charge
