2. Sicherheitsvorkehrungen
Adhering to these safety guidelines is crucial for safe operation and to prevent damage or injury.
- Do not connect the inverter directly to grid power. This unit is designed for DC battery input only.
- Auf richtige Polarität achten. Reverse connection of positive and negative terminals is strictly forbidden and will damage the inverter.
- Vermeiden Sie eine Überlastung des Wechselrichters. If connecting inductive loads (e.g., motors, refrigerators), select an inverter with a continuous power rating 3-7 times higher than the appliance's wattage. For refrigerators, a 10 times higher power inverter is recommended due to high startup current.
- Proper power-up sequence: Always turn off the load first, then turn off the inverter. When powering on, turn on the inverter first, then turn on your loads. This ensures stable output, especially with the soft start function.
- Monitor indicator lights: Ein blinkendes rotes Licht zeigt an, dass die Eingangslautstärketage ist etwas zu hoch.
- Use provided cables: Always use the standard battery cables supplied with the inverter to ensure full output capacity.
- Interne Sicherungen: The inverter has built-in fuses for safety. Spare fuses are included in the package.
- Kühlung: The intelligent cooling fan activates when the internal temperature exceeds 66 degrees Celsius to prevent overheating. Ensure adequate ventilation around the unit.

4. Einrichtung und Installation
Follow these steps to properly set up your WZRELB power inverter.
- Wählen Sie einen geeigneten Standort: Place the inverter in a dry, well-ventilated area, away from direct sunlight, heat sources, and flammable materials. Ensure there is enough space around the unit for proper airflow, especially for the cooling fans.
- Prepare the battery: Ensure your 48V battery bank is fully charged and capable of providing the necessary current for your applications.
- Connect the battery cables:
- Verbinden Sie rot (positiv) Batteriekabel zum Pluspol (+) am Wechselrichter.
- Verbinden Sie schwarz (negativ) Batteriekabel zum Minuspol (-) am Wechselrichter.
- Ensure connections are tight and secure to prevent arcing and power loss.

7. Fehlerbehebung
In diesem Abschnitt werden häufig auftretende Probleme behandelt, die bei Ihrem Wechselrichter auftreten können.
| Problem | Mögliche Ursache | Lösung |
|---|---|---|
| Wechselrichter schaltet sich nicht ein | Lose Batterieanschlüsse, niedriger Batteriestandtage, defekter Ein-/Ausschalter. | Check battery cable connections for tightness. Verify battery voltage is within the 42V-60V operating range. Ensure the ON/OFF switch is fully engaged. |
| Kein AC-Ausgang | Überlastung, Kurzschluss, zu niedrige/zu hohe Eingangsspannungtage, Wechselrichterfehler. | Reduce the load. Check for short circuits in connected appliances. Verify input voltage. If the inverter has shut off due to overload, disconnect the load and manually recover by cycling the power. |
| Blinkendes rotes Licht | Eingangsvolumentage ist etwas zu hoch. | Monitor the DC input voltage. Ensure it remains within the safe operating range (42V-60V). If it consistently exceeds this, check your battery charging system. |
| Lüfter läuft nicht | Normal operation (temperature below 50°C), fan malfunction. | The fan only runs when the internal temperature exceeds 50°C. If the inverter is hot and the fan is not running, contact customer support. |
| Reduced output power | Insufficient battery cable gauge, long cables, low battery charge. | Ensure you are using the provided standard battery cables. Shorter, thicker cables can improve performance. Recharge your battery. |
