Key Features

1. High Tracking Efficiency: Advanced MPPT technology ensures fast and stable tracking of the maximum power point, with high tracking efficiency of up to 99% and peak conversion efficiency of 98%. It auto-detects 12V or 24V DC system voltages.
2. Parallel Charge Function: Two HQST MPPT controllers of the same series can work together to charge the same battery with a parallel charge cable (not included), meeting high power charging requirements. Both controllers should be set to the same battery voltage.
3. LCD Screen Display & Remote Monitoring: Equipped with an LCD screen and LED fault indicators, it allows you to check device operating data and status. Built-in Bluetooth module enables remote monitoring via the "ChargePro 2.0" or "PVChargePro" app, storing 300 days of historical data.
4. Higher Heat Dissipation Efficiency & Full-Load Working: Die-cast aluminum heat sink enhances heat dissipation efficiency, minimizing power loss from heat. Internal gel filling improves PCBA cooling conduction and protects against water damage, extending the controller's service life.
5. Compatible with Multiple Battery Types: Compatible with Flooded, AGM, Gel, and Lithium batteries. User mode allows custom charging parameters. Features 3-stage charging: boost, float, and equalization.
