【HIGH TRACKING EFFICIENCY】- Solar charge controller adopts advanced MPPT technology that ensures fast and stable track the maximum power point, high tracking efficiency of up to 99%, and peak conversion efficiency of 98%. Maximizing the energy from solar panels to charge your system. It auto detects 12V or 24V DC system voltages.
【MULTIPLE ELECTRONIC PROTECTION】- Negative Ground Controller offers overcharging/over discharging/ overload/ overheat/ short circuit/ reverse protection. Maximum degree avoids the damage due to system fault or installation error.
【LCD SCREEN DISPLAY & REMOTE MONITORING】- 20A/40A solar controller is equipped with an LCD screen and LED fault indicators, which can not only check device operating data and status but quickly determine system faults and modify controller parameters. Built-in Bluetooth module, you can download the ‘’ChargePro 2.0'' (new version) or "PVChargePro'' (old version) app for remote monitoring that keeps 300 days of historical data.
【HIGH HEAT DISSIPATION EFFICIENCY】- Die-cast aluminum heat sink makes the heat dissipation efficiency higher, which can minimize the power loss from heat.
Using temperature sensors to compensate for battery charging voltage can extend battery life and improve system performance.
【COMPATIBLE WITH MULTIPLE BATTERY TYPES】- The mppt solar charge controller is compatible with Flooded, AGM, Gel, Lithium batteries. User mode allows the buyer to set their charging parameters. 3-Stage Charging: boost, float, and equalization.

Die-cast Aluminum Design
Die-cast aluminum heat sink allows for efficient natural heat dissipation.
RS485 Communication PORTS
Support for external LCD screen/ Bluetooth module.
Built-in Bluetooth Module
Easy for checking real-time data and setting parameters via mobile phone APP that keeps 300 days of historical data.
Temperature Sensor
It senses the environment temperature. Put this sensor near the battery.
Higher Heat Dissipation Efficiency and Charging Power
The MPPT solar controller filled with gel inside is more efficient to dissipate heat. Compared with conventional MPPT controllers, the HQST controllers can increase the charging capacity by at least 8% at high temperature.
After testing, under the same full load, the charging power of conventional MPPT controllers decreased by 60% after 20 minutes, and the charging power of the HQST MPPT controller only decreased by 8% after 90 minutes of operation.
