HQST 60 Amp MPPT Solar Charge Controller for 12V/24V/36V/48V Negative Grounded Systems with Bluetooth and Lithium Battery Protection

Unleash your energy independence by installing a solar system using our high-quality and cost-efficient solar-powered products, including solar panels, charge controllers, batteries, inverters, and other required mounting accessories. We prioritize product quality and service over everything else. We provide a quick response service whenever you encounter any issues during usage, helping DIY your solar system with ease.

The HQST 48V 60A solar controller is equipped with an LCD screen and LED fault indicators, which can check device operating data and modify controller parameters. It 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.

Two 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. The two controllers should be set to the same battery pack voltage. The controller is compatible with Flooded, AGM, Gel, and Lithium batteries. The user mode allows the buyer to set their charging parameters. It supports 3-Stage Charging: boost, float, and equalization.

The 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.

The 48V 60 amp solar charge controller adopts advanced MPPT technology that ensures fast and stable track of the maximum power point, high tracking efficiency of up to 99%, and peak conversion efficiency of 98%. This maximizes the energy from solar panels to charge your system. It automatically detects 12V, 24V, 36V, or 48V DC system voltages, making it suitable for RVs, Commercial Vehicles, Boats, Yachts, and any off-grid system.

For Android users, to connect Bluetooth, first allow location, then tap the BT icon in the app and select PVChargePro. For iOS users, tap the BT icon in the app and select PVChargePro. If the DC load stops working, try the following solutions: 1) Set the load mode to 17, 2) Check the indicators for abnormalities, 3) Press the 'return' key on the controller, and 4) Open ChargePro2.0, enter the Real-Time Monitoring page, and turn off the DC Load Short-circuit Protection.
