HQST Solar Charge Controller 20A MPPT 12V 24V Gel Sealed Flooded

Key Feature 【HIGH CONVERSION EFFICIENCY】- Solar panel controller adopts advanced MPPT technology that ensures fast and stable track the maximum power point, high tracking efficiency of up to 99.9%, and peak conversion efficiency of 98%. Maximizing solar input from the panels to the batteries. It auto-detects 12V or 24V DC system voltages. 【MULTIPLE ELECTRONIC PROTECTION】- 20A MPPT solar charge controller offers overcharging/over current/overload/overheat/short circuit/reverse current/ reverse polarity protection. Maximum degree avoids the damage due to system fault or installation error. 【COMPATIBLE WITH MULTIPLE BATTERY TYPES】- The 12V mppt solar charge controller is compatible with sealed, vented, colloidal, lithium batteries. User mode allows the buyer to set their charging parameters. 5-Stage Charging: quick, holding, boost, float, and equalization. 【HIGH HEAT DISSIPATION EFFICIENCY】- HQST compact Solar MPPT charge controller adopts die-cast aluminum heat sink to make heat dissipation more efficient, which can minimize the power loss from heat. Using temperature sensors to compensate for battery charging voltage can extend battery life and improve system performance. 【FASTER】- PowerCatcher MPPT technology compared with the traditional MPPT tracking technology, HQST charge controllers for solar panels boast faster response speed and higher tracking efficiency by 20%. LED screen can display system operating information and error codes. 20A MPPT Charge Controller -Auto-recognition of 12/24V battery system. -Advanced MPPT Technology with up to 99% high tracking efficiency, 98% conversion efficiency. -External LCD screen or Bluetooth module can be connected. -Provide an active charging voltage regulation feature. -A current-limited charging mode is available. -Support standard Modbus protocol to meet communication needs in different occasions. -Built-in over-temperature protection mechanism. -Battery System Voltage: 12V/24V - Rated Solar Charge Current: 20A - Max PV Input Voltage: 100V - Temperature Compensation Coefficient: -3mV/℃/2V - Operating Temperature: -35℃-60℃ - Communication Method: TTL(3.3V) - Connection Terminal：8AWG -1-year material warranty LCD Display -Input voltage:5-12V -Connection Cable Length:60 inch -Operating Temperature:-31℉-149℉ -IP Rating: IP32 -Weight：0.31lb -Dimensions:4.11 x 2.19 x 0.46 in -1-year material warranty Die-cast Aluminum Design                                               Remote Meter                                                   Communication Interface Die-cast aluminum heat sink allows for efficient natural     LED screen displays and sets the real time               Support for Modbus Communication Interface heat dissipation.                                                                operational data and the working status.                   and external temperature sensor interface.
