Description

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 (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】- 20A solar controller is equipped with an LCD screen and LED fault indicators, which can only check device operating data and status but quickly determine system faults and modify controller parameters.

【HIGHER HEAT DISSIPATION EFFICIENCY & FULL-LOAD WORKING】- Die-cast aluminum heat sink makes the heat dissipation efficiency higher, which can minimize the power loss from heat. Filling inside the controller with gel is for better PCBA cooling conduction and prevents water and other damages, extending the controller service life. With the IC and better PCBA, this controller can work under full load even in high temperature environment.
【COMPATIBLE WITH MULTIPLE BATTERY TYPES】- The mppt solar charge controller is compatible with Flooded, AGM, Gel, and Lithium batteries. User mode allows the buyer to set their charging parameters. 3-Stage Charging: boost, float, and equalization. HQST provides a 3-year warranty and lifetime technical support.
