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

HQST Solar System: Unleash Your Energy Independence

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, providing a quick response service whenever you encounter any issues during usage, helping you DIY your solar system with ease.

【LCD Screen Display & Remote Monitoring】 The HQST 48V 60A solar controller is equipped with an LCD screen and LED fault indicators, allowing you to check device operating data and modify controller parameters. It also features a built-in Bluetooth module, enabling you to download the "ChargePro 2.0" (new version) or the "PVChargePro" (old version) app for remote monitoring that keeps 300 days of historical data. (Note: The Android version app requires location and Bluetooth to be turned on for connection.)

【Low Temperature Protection for Li Battery】 The 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 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.

【Parallel Charge Function】 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), meeting 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, and the user mode allows the buyer to set their charging parameters. It supports 3-Stage Charging: boost, float, and equalization.

【Higher Heat Dissipation Efficiency & Full-Load Working】 The die-cast aluminum heat sink ensures higher heat dissipation efficiency, minimizing power loss from heat. The controller is filled with gel for better PCBA cooling conduction and protection against water and other damages, extending the controller's service life. With premium IC and better PCBA, this controller can work under full load even in high-temperature environments.

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