Our new 100 Amp MPPT solar charge controller offers high tracking efficiency of up to 99% and a peak conversion efficiency of 98.7% , about 30% higher than PWM. With Bluetooth app control, you can monitor all data in real-time. It also features low-temperature cut-off protection for LiFePO4 batteries, preventing damage to your valuable batteries. Ten protection mechanisms and an active cooling fan system ensure consistent efficiency at all times. Perfect for all off-grid applications, including RVs, cabins, motorhomes, and boats. 

 Description

• 【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.
  

When using high-capacity (large gauge) cables, you may find that the controller’s terminal port is too small to accommodate them. Here’s a recommended workaround:

1. Use a short 6 AWG cable (2 in / 5 cm) from the charge controller to the battery. Crimp a wire ferrule on one end and connect it to the controller’s BAT terminal.

2. Connect the other end, with a ring terminal, to a bus bar (power distribution block).

3. From the bus bar, run a single 3 AWG cable or dual 6 AWG cables directly to your battery terminal.

Note: Connection cables, wire ferrules, and bus bar are not included.
