60A MPPT Solar Charge Controller with Li-Ion Battery Low Temp Protection, Parallel Charging, and Bluetooth

OVERVIEW

Important Notice:

• 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. 

Key Features

Low-Temp Cut-Off Protection for LiFePO4

The HQST 60A MPPT solar charge controller features low-temp charging (below 32℉) and discharging (below 5℉) cut-off protection for LiFePO4 batteries, preventing damage to your valuable batteries. You can manually switch on and off this function. The controller can also activate dormant LiFePO4 batteries that have turned off due to over-discharging.

Smart APP Control & LCD Display

With a built-in Bluetooth module, you can download the "ChargePro 2.0" (new version) or "PVChargePro" (old version) app for remote monitoring, which stores 300 days of historical data. The LCD screen and LED fault indicators allow you to check device operating data and modify controller parameters. Note: The Android version of the app requires location and Bluetooth to be turned on for connection.

High-Efficiency Charging

The HQST 60A solar charge controller uses advanced MPPT technology to quickly and stably track the maximum power point, with a high tracking efficiency of up to 99% and a peak conversion efficiency of 98%. This maximizes energy from solar panels to charge your system. It auto-detects 12V, 24V, 36V, 48V battery system, with a maximum load output current of 20A. If the load exceeds 20A (240 watts), overvoltage protection will turn off the output.

Parallel Charge Function

Two HQST MPPT controllers (M2420N/M2440N/M4860N) can work together to charge the same battery pack using a parallel charge cable (not included), meeting high power charging requirements. Both controllers should be set to the same battery voltage. Our negative-grounded controller provides protection against overcharging, over-discharging, overload, overheating, short circuits, and reverse polarity, maximizing protection against system faults or installation errors.
