- Regarding the low-temperature protection feature for Li-ion batteries, it is ONLY available in the 60 Amp version. The 20 Amp and 40 Amp versions do NOT include this feature.
- All three MPPT charge controllers support parallel charging and can be controlled via the Bluetooth app.
HQST 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 60 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.
LCD SCREEN DISPLAY & REMOTE MONITORING
Built-in Bluetooth module, you can download the ‘’ChargePro 2.0'' (new version) or the "PVChargePro'' (old version) app for remote monitoring that keeps 300 days of historical data. HQST 48V 60A 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.
LOW TEMPERATURE PROTECTION FOR LI BATTERY
HQST 60 Amp MPPT negative grounded controller offers overcharging/over-discharging/overload/overheat/short circuit/reverse protection and Lithium battery low-temperature protection. The maximum degree avoids the damage due to system fault or installation error. The BMS of low temp protection for Li battery automatically identifies low temperature, stops charging Li battery, and protects its life. This function can be switched on and off manually.
PARALELL CHARGE FUNCTION
2 HQST MPPT controllers of the same series(M2420N/M2440N/M4860N) can work together to charge the same battery with the parallel charge cable (not included), to meet high power charging requirements and 2 controllers should set the same battery pack voltage. Compatible with Flooded, AGM, Gel, and Lithium batteries. User mode allows the buyer to set their charging parameters. 3-Stage Charging: boost, float, and equalization.
HIGHER HEAT DISSIPATION EFFICIENCY & FULL-LOAD WORKING
Die-cast aluminum heat sink makes the heat dissipation efficiency higher, which can minimize the power loss from heat. Filling inside the controller with gel is for better PCBA cooling conduction and prevents water and other damages, extending the controller service life. With the premium IC and better PCBA, this controller can work under full load even at high temperature environment.
HIGH TRACKING EFFICIENCY
HQST 48V 60A solar charge controller adopts advanced MPPT technology that ensures fast and stable track of of 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. Automatically detects 12V, 24V, 36V, or 48V DC system voltages, which is suitable for RVs, Commercial Vehicles, Boats, Yachts, and any off-grid system.
