HQST 20 Amp MPPT Charge Controller applied Advanced Maximum Power Point Tracking (MPPT) technology to help regulate the power from your solar panel to battery with efficiency no less than 99.5%. This 20 Amp MPPT solar regulator adopts high quality components with maximum conversion efficiency of 98%. The MPPT battery charging can greatly increase the lifetime of your battery and has various unique functions and quite easy to use features.
With MPPT control algorithm, in any situation, products of this series can fast and accurately track out the best maximum power point (MPP) of photovoltaic array to obtain the maximum solar energy in time, which remarkably improves energy efficiency. There is dual display function: local LCD panel and remote meter. With Modbus communication protocol interface, it is convenient for customers to expand applications and monitor in various fields like telecommunication base station, household system, street lighting system, wilderness monitoring system, etc.
All-round electronic fault self-test function and enhanced electronic protection function could furthest avoid damages on system components resulting from installation errors or system failures.
The Controller is Common Positive Grounding.
Note: This controller only compatible with Renogy MT-50.
