3.2 Kabelverbindungen
Follow the wiring sequence below to prevent damage to the controller or battery. Always connect the battery first, then the solar panels, and finally the load.
- Schließen Sie die Batterie an: Connect the positive and negative battery wires to the corresponding battery terminals on the charge controller. Ensure a secure connection.
- Schließen Sie die Solarpaneele an: Connect the positive and negative solar panel wires to the corresponding PV input terminals on the charge controller. Ensure solar panels are covered or disconnected during wiring to prevent electrical shock.
- Gleichstromlast anschließen (optional): If using a DC load directly from the controller, connect its positive and negative wires to the DC load output terminals.
- Temperatursensor anschließen: Plug the external temperature sensor into the designated port on the controller and attach the other end to the battery side for accurate temperature monitoring.

4.3 Parallel Charging Setup
For higher power charging requirements, two HQST MPPT controllers of the same series (M2420N/M2440N/M4860N) can work in parallel to charge the same battery bank. A parallel charge cable (not included) is required.
- Connect both controllers to a single battery bank.
- Connect two solar panels to the respective controllers.
- Plug in the RS485 parallel charge connection cable between the two controllers.
- Press and hold the first and third buttons simultaneously on each controller until the parallel charge page appears.
- Select "Parallel Charging ON" and press the first button to save and exit.
- Repeat for the second controller.
