This 40 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. Description 【Low-Temp Cut-Off Protection for LiFePO4】The HQST 40A MPPT solar charge controller features low-temp charging (below 32℉) and discharging (below 5℉) cut-off protection for LiFePO4 batteries, preventing damage to your valuable batteries. You can manually switch on and off this function. The controller can also activate dormant LiFePO4 batteries that have turned off due to over-discharging. 【Smart APP Control & LCD Display】With a built-in Bluetooth module, you can download the “ChargePro 2.0” (new version) or “PVChargePro” (old version) app for remote monitoring, which stores 300 days of historical data. The LCD screen and LED fault indicators allow you to check device operating data and modify controller parameters. Note: The Android version of the app requires location and Bluetooth to be turned on for connection. 【High-Efficiency Charging】The HQST 12V/24V 40A solar charge controller uses advanced MPPT technology to quickly and stably track the maximum power point, with a high tracking efficiency of up to 99% and a peak conversion efficiency of 98%. This maximizes energy from solar panels to charge your system. It auto-detects 12V or 24V DC system voltages, with a maximum load output current of 20A. If the load exceeds 20A (240 watts), overvoltage protection will turn off the output. 【Parallel Charge Function】Two HQST MPPT controllers (M2420N/M2440N/M4860N) can work together to charge the same battery pack using a parallel charge cable (not included), meeting high power charging requirements. Both controllers should be set to the same battery voltage. Our negative-grounded controller provides protection against overcharging, over-discharging, overload, overheating, short circuits, and reverse polarity, maximizing protection against system faults or installation errors. 【Higher Heat Dissipation Efficiency & Full-Load Working】The die-cast aluminum heat sink enhances heat dissipation efficiency, minimizing power loss due to heat. The internal gel filling improves PCBA cooling conduction and protects against water and other damages, extending the controller’s service life. Equipped with a premium IC and superior PCBA, this controller can operate at full load even in high-temperature environments.
