HQST 30 A MPPT solar charge controller is a Positive Grounding controller, that's to say, you cannot have more than 1 grounding from a positive connector. The controller features an LCD display which dynamically displays the device's operating data and working condition. This controller doesn't have any LED indicators. The battery temperature compensation feature tracks the battery's working temperature and adjusts the charging parameters to compensate for temperature increase thus prolonging the battery's life. The controller supports external loads. The load control modes are manual, light on/off, light on + timer and test. Interestingly enough, the controller supports multiple data communication methods:
- use the RJ45-to-RJ45 cable to connect to the MT-50 external display unit.
- use the RJ45-to-RJ45 cable to connect to Super Parameter Programmer (SPP-02) then connect SPP to PC via USB cable
- use RJ45-RS485-to-USB cable to connect directly to the PC
- use RJ45-RS485-to-USB cable to connect to an Android mobile phone through an OTG cable
