Description
Technical Parameters
SMR-MPPT series solar controller, designed for the use of solar energy systems intelligent programming MPPT controller. The charging efficiency is about 20% higher than the traditional PWM controller, which can drop the cost of the whole system.
- Innovative Maximum Power Point Tracking(MPPT) technology, tracking efficiency >99.9%.
- High charge conversion efficiency up to 97.2% .
- Monitoring of the running status and parameters.
- Dual automatic limit function for rated charging current and charging power.
- Clear and easy to understand charging and discharging, fault indication.
- Suitable for Gel, Liquid, AGM and Lithium battery.
- External temperature sensor with automatic temperature compensation.
- Automatic over-temperature power reduction function .
- Four stage charging: MPPT, boost, equalization, float.
- When BMS power off because of LVD, it can activate the system automatically.
- The battery and mains power (DC) complement each other, and the load power supply priority can be set. The controller automatically switches between the two according to the setting to ensure the normal operation of the load.
- 0℃ Charging Protection(Lithium).
- Based RS-485 standard Modbus protocol.
- Equipped with buttons and digital tubes for quick setting of controller parameters.
- The communication interface provides external power supply.
- Waterproof IP67, Strong and durable aluminum case.
- Perfect EMC & thermal design.
- Full automatic electronic protect function
