100A MPPT Solar Charge Controller with Smart APP Control, LiFePO4 Battery Low Temp Protection, and Parallel Charging

SKU: HCC100HTR-FC
$169.99 $309.99

  • 【Bluetooth 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 real-time monitoring, which stores 300 days of historical data. The LCD screen and buttons on the machine allow you to check device operating data and modify controller parameters. Note: Bluetooth connection is effective within a 10m/33ft range (in an unobstructed area).
  • 【Low-Temp Cut-Off Protection for LiFePO4】This HQST 100A 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. This controller can also activate dormant LiFePO4 batteries that have turned off due to over-discharging.
  • 【Improved High-Efficiency Charging】The HQST 100A MPPT charge controller uses advanced MPPT technology, achieving a high tracking efficiency of up to 99% and a peak conversion efficiency of 98.7%, which is about 30% higher than PWM. This maximizes energy from your solar panels to charge your system. It supports 12V, 24V, 36V, and 48V battery systems and is compatible with lithium iron phosphate (LiFePO4), sealed, AGM, GEL, flooded, and user-customized battery types.
  • 【Parallel Charge Extension Function】To increase the charging current for your single battery bank system, you don’t need to reinstall the entire solar panel system. You can connect up to 9 of our MPPT controllers (M4880F/M48100F models) together using parallel charge cables (not included) to charge the same battery pack, meeting high power charging requirements. Ensure all controllers are set to the same battery voltage.
  • 【Active Cooling Fan System & Comprehensive Safety Protection】Two built-in fans start cooling automatically when the charge controller runs at high power or exceeds 113℉, ensuring consistent efficiency. Our negative grounding controller offers 10 protections against overcharging, over-voltage, over-current, overheating, and reverse polarity, maximizing protection against system faults and installation errors.

Does this have a low-temperature shutdown function?

Yes, it does. It features low-temperature charging (below 32℉) and discharging (below 5℉) cut-off protection for LiFePO4 batteries (not for sealed), preventing damage to your valuable batteries.

Do I need to be connected to the internet or cellular networks when using the app control?

No, our app control and monitoring is via Bluetooth connection. As long as your phone is within range of the Bluetooth device (10m/33ft), you can access and connect to monitor and adjust settings.

Can its parameters be adjusted without the Bluetooth app?

Yes. You can adjust the parameters using the buttons on the controller. Refer to the user manual for detailed instructions. However, we highly recommend using the Bluetooth app, as it is easier and more convenient for operation and monitoring.

What size wire can be connected to this charge controller?

We recommend using 2 AWG or larger wire. When it comes to cable gauges, the lower the gauge number, the thicker the wire.

Why is my controller flashing the error message E02?

E02 flashes when the controller detects relatively high voltages. When a Li battery is fully charged, its BMS generates a high voltage (about 18V) and then stops charging. This does no harm to your controller or battery.

My controller stops charging when it is nearly at full load (100A).

If this happens, please contact our support team. You can find our contact information in the user manual.
