5.2 Connecting Solar Panels (DC Input)
The inverter features pre-installed MC4 connectors for direct connection to your solar panels. Ensure that the solar panel voltagه و واتtage are within the inverter's specifications (22-50VDC, max 700W total, with each MC4 branch not exceeding 350W). Connect the positive and negative terminals of your solar panels to the corresponding MC4 input connectors on the inverter.

6. تعليمات التشغيل
6.1 تشغيل
Once all connections are secure, connect the AC output plug to the grid. The inverter will automatically power on and begin its startup sequence.
6.2 مؤشرات LED
The inverter features an LED display for status indication:
- Red ON for 3 seconds: Device starts.
- Green/Red flash: Inverter Working.
- ثابت الأحمر: Error/Inverter protection activated.
- Green lights on 3s and off 0.5s: MPPT locked (Maximum Power Point Tracking).
6.3 Maximum Power Point Tracking (MPPT)
The inverter incorporates high-precision MPPT technology to automatically adjust the solar panel output power to its maximum point, ensuring efficient and steady power generation, even in varying light conditions. In overcast weather, the inverter will activate a 6-grade power search function to maintain optimal output.
6.4 LCD Display Monitoring
The included LCD display unit provides real-time monitoring of key operational parameters such as voltage, current, power, energy, frequency, and power factor. This allows you to observe the inverter's performance directly.
7. الصيانة
The PowMr 700W Solar Micro Inverter is designed for minimal maintenance. Its IP67 waterproof rating and self-cooling aluminum alloy casing contribute to its durability.
- التفتيش الدوري: Periodically check all cable connections for tightness and signs of wear or damage.
- تنظيف: Ensure the inverter's casing and heat sink fins are free from dust, dirt, or debris to maintain optimal heat dissipation. Use a soft, dry cloth for cleaning. Do not use harsh chemicals or abrasive materials.
- تهوية: Confirm that the area around the inverter remains clear to allow for adequate airflow and prevent overheating.
8. استكشاف الأخطاء وإصلاحها
If you encounter issues with your micro inverter, refer to the following common problems and solutions:
| مشكلة | السبب المحتمل | حل |
|---|---|---|
| No power output / Inverter not starting | No DC input from solar panels; AC grid not connected; Faulty wiring. | Check solar panel connections and ensure sufficient sunlight. Verify AC plug is securely connected to a live outlet. Inspect all wiring for damage. |
| انخفاض انتاج الطاقة | Insufficient sunlight; Shading on solar panels; Solar panel degradation; Inverter overheating. | Ensure panels are clean and free from shade. Check panel orientation. Verify inverter is not overheating by ensuring proper ventilation. |
| Inverter shuts down frequently (Red steady LED) | Overheating; Over-voltagه / تحت المجلدtage protection; Grid instability. | Improve ventilation around the inverter. Check solar panel voltage is within range. Consult with an electrician to check grid stability. Allow inverter to cool down before restarting. |
| شاشة LCD لا تعمل | Loose connection; Display unit fault. | Ensure the LCD display unit is securely connected to the inverter and the AC outlet. If issues persist, contact customer support. |
