HQST MPPT Solar Charge Controller 20 Amp Negative Grounded Controller with Bluetooth LCD Display, 12V/24V DC Input Solar Panel Regulator for Gel Sealed Flooded and Lithium Battery
- 【HIGH TRACKING EFFICIENCY】- HQST 12V 20 amp Solar charge controller adopts advanced MPPT technology that ensures fast and stable track of the maximum power point, high tracking efficiency of up to 99%, and peak conversion efficiency of 98%. Maximizing the energy from solar panels to charge your system. It auto-detects 12V or 24V DC system voltages. The max load output current is 20A. If it exceeds the 20 amp DC load (240 watts), the overvoltage protection will turn off the output..
- 【PARALELL CHARGE FUNCTION】- 2 HQST MPPT controllers of the same series(M2420N/M2440N/M4860N) can work together to charge the same battery with the parallel charge cable (not included), to meet high power charging requirements and 2 controllers should set the same battery pack voltage. Our negative grounded controller offers overcharging/over-discharging/overload/overheat/short circuit/reverse protection. The maximum degree avoids the damage due to system fault or installation error..
- 【LCD SCREEN DISPLAY & REMOTE MONITORING】- 40A solar controller is equipped with an LCD screen and LED fault indicators, which can check device operating data and modify controller parameters. Built-in Bluetooth module, you can download the ‘’ChargePro 2.0'' (new version) or the "....
