LCD display solar charge controller for off grid pv system
Key Features
1>:DC12V/24V/48V battery system automatic detect, users can use it in different system easily.
2>:eSmart Controller with peak efficiency up to 99% under MPPT charging mode, can save 30%~60% power compared with traditional PWM controller.
3>:RS232 and LAN communication port. IP and Gate address could be user define it satisfy global area.And communication protocol can be provided to manage all information.
4>:The Setting Parameter Possess The Saving Function Which Makes The Parameter.
5>:Discharge type owns always on pattern and always off pattern, it also has PV voltage solar controlling switch pattern.
6>:With temperature compensation,can adjust the battery charging parameters according to the environmental temperature automatically.
7>:Electronic protection: Overheating, over charging, over discharging, overload, and short circuit
8>:CE, RoHS Certifications approved; cooperating with clients through the other certifications.
9>:2 years warranty; 3~10 years extended technical service.
10>:Equipment integrity: controller + CD-ROM(microcomputer software) + communication wire + temperature sensing wire + Anderson terminals.
11>:Digital tube can display battery voltage and charging current. The software can display various parameters such as model number, PV input voltage, battery type, battery voltage, charging current, charging power, working condition.
