HQST MPPT Solar Charge Controller with Bluetooth LCD Display, 12V/24V DC Input Solar Panel Regulator

HQST Solar Charge Controller: Unleash Your Energy Independence

HQST prioritizes product quality and service, providing high-quality and cost-efficient solar-powered products, including solar panels, charge controllers, batteries, inverters, and other required mounting accessories. The company is committed to offering a quick response service whenever customers encounter any issues during usage, helping them DIY their solar system with ease.

The HQST 12V 40 amp solar charge controller boasts 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 feature maximizes the energy from solar panels to charge your system, which auto-detects 12V or 24V DC system voltages. The max load output current is 20A, and if it exceeds this limit (240 watts), the over voltage protection will turn off the output.

The parallel charge function of the HQST MPPT controllers allows two controllers of the same series (M2420N/M2440N/M4860N) to work together to charge the same battery with the parallel charge cable (not included), meeting high power charging requirements. The controllers should be set to the same battery pack voltage. The negative grounded controller offers overcharging/over-discharging/overload/overheat/short circuit/reverse protection, ensuring maximum safety and avoiding damage due to system fault or installation error.

The 40A solar controller is equipped with an LCD screen and LED fault indicators, allowing users to check device operating data and modify controller parameters. The built-in Bluetooth module enables remote monitoring through the "ChargePro 2.0" (new version) or the "PVChargePro" (old version) app, which keeps 300 days of historical data. For Android users, location permission is required, and for iOS users, the Bluetooth icon in the app must be tapped to select "PVChargePro."

The HQST solar charge controller boasts higher heat dissipation efficiency and full-load working capability. The die-cast aluminum heat sink enhances heat dissipation, minimizing power loss from heat. The gel-filled interior provides better PCBA cooling conduction and protects against water and other damages, extending the controller's service life. The premium IC and better PCBA enable the controller to work under full load even in high-temperature environments.

The MPPT solar charge controller is compatible with various battery types, including Flooded, AGM, Gel, and Lithium. The user mode allows buyers to set their own charging parameters. The 3-stage charging process includes boost, float, and equalization. HQST offers a 3-year warranty and lifetime technical support, ensuring customer satisfaction.
