4.2 דראָט דיאַגראַמע און קאַנעקשאַנז
Follow the wiring sequence below. Incorrect wiring can damage the controller or batteries.
- Connect Battery 1 (Main/Service Battery): Connect the positive and negative terminals of your main battery to the BATT1 terminals on the controller. Use appropriate cable gauge (e.g., 16 mm² / AWG6). Ensure correct polarity.
- Connect Battery 2 (Starter Battery): Connect the positive and negative terminals of your starter battery to the BATT2 terminals on the controller. Use appropriate cable gauge (e.g., 4 mm² / AWG12). Ensure correct polarity.
- Connect Solar Panels (PV): Connect the positive and negative terminals of your solar panel array to the PV terminals on the controller. Ensure the open-circuit voltage of your solar array does not exceed 100V.
- Connect Temperature Sensors: The controller includes ports for temperature sensors. Connect the provided sensor to monitor battery temperature for optimized charging.
- אָפּטיאָנאַל קאַנעקשאַנז:
- RS485 קאָמוניקאַציע: For connecting an optional remote display or USB adapter for PC communication.
- AES Signal Output: For controlling car refrigerators to prevent excessive discharge of the main battery.
- גראָונדינג: Ensure the controller is properly grounded (negative grounding).

5.1 ערשט מאַכט-אַרויף
After all connections are securely made, connect the battery power first, then the solar panel power. The controller will perform a self-test, and the LED indicators will illuminate.
5.2 Setting Battery Type (BATT1)
The controller supports various battery types for the main battery (BATT1). To select the correct battery type:
- דריקן און האַלטן די שטעלן button for approximately 5 seconds until the battery type indicator starts flashing.
- דרוק די שטעלן button repeatedly to cycle through the available battery types (Gel, Flooded, LiFePO4, Li-NiCoMn).
- Once the desired battery type is selected, wait for 5 seconds without pressing any button. The indicator will stop flashing, and the setting will be saved.
The secondary battery (BATT2) is typically charged as a lead-acid battery and does not require specific type selection.
5.3 געפירט ינדיקאַטאָרס
The front panel features LED indicators to show the operational status:
- PV Status LED: Indicates solar panel input status.
- BATT1 Status LEDs: Show the charging stage and state of charge for the main battery.
- BATT2 Status LED: Indicates charging status for the starter battery.
- טעות LED: Illuminates to indicate a fault or warning. Refer to the troubleshooting section.
