MPPT Solar Regulator Solar Charge Controller MC48V60-70A

Description

1. With the PowerCatcher MPPT technology, the controller is able to track the maximum power point of solar panels even in a complex environment. It has higher response speed and tracking efficiency compared with those controllers with traditional MPPT technology.

2. The maximum power point tracking algorithm can significantly improve the energy utilization efficiency of photovoltaic systems. The charging efficiency is 15% to 20% higher than the conventional PWM method.

3. MPPT Tracking efficiency is up to 99.9%.

4. Advanced digital power technology raises the circuit energy conversion efficiency to 98%.

5. The controller features a limited current charging mode. When the solar panel power exceeds a certain level and charging current is larger than the rated current, the controller will automatically lower the charging power and bring the charging current to the rated level.

6. Support charging lithium batteries, gel batteries, sealed batteries and vented batteries, etc.

7. The controller has an overheat protection mechanism. With charging line loss compensation, the voltage of the battery terminal can be accurately controlled.

8. The controller features a limited current charging mode. When the solar panel power exceeds a certain level and charging current is larger than the rated current, the controller will automatically lower the charging power and bring the charging current to the rated level.

9. The controller has an overheat protection mechanism. When the temperature exceeds the set value, the charging current will decline in linear proportion and discharging will be shut off so as to curb the temperature rise of the controller and keep the controller from being damaged by overheat.

10. It supports parallel operation and meets need of greater charging power.

11. With embedded bluetooth 4.0BLE module, it can achieve data interaction with APP on mobile phone.

12. Supports standard Modbus protocol and provides protocol technology support to facilitate secondary development and application by users.

13. Programmable relay output.
