5.3 Фотоэлектрик модулийн холболт

Connect your solar panel(s) to the PV input connectors on the micro inverter. Ensure the Vmp and Voc of your solar panels are within the recommended range (Vmp 30-42V; Voc 38-60V) and the total power does not exceed 350W.

5.4 AC Grid Connection

The micro inverter connects to your AC electrical grid. There are typically two types of AC cable connections:

1. Direct Wiring: For direct wiring, connect the green/yellow wire to Ground (G), the blue wire to Neutral (N), and the brown wire to Live (L). An AC plug (not included) will be required for this method.
2. Pre-assembled Cable: Some packages may include a pre-assembled AC cable with a plug for direct connection to an outlet.

5.5 Суурилуулалтын орчин

Install the inverter in a well-ventilated, cool area, protected from direct rain and excessive heat. Proper ventilation helps maintain optimal operating temperatures and extends the lifespan of the unit.

7. Засвар үйлчилгээ

Regular maintenance helps ensure the longevity and optimal performance of your micro inverter.

• Цэвэрлэгээ: Periodically clean the exterior of the inverter to prevent dust and debris buildup, which can hinder heat dissipation.
• Агааржуулалт: Ensure the installation area remains well-ventilated and free from obstructions. Adequate airflow is critical for cooling the inverter, especially during peak operation. Consider supplemental cooling (e.g., fans) if the inverter frequently runs hot in its environment.
• Холболтын шалгалт: Regularly inspect all electrical connections (PV input and AC output) for tightness and signs of wear or corrosion.
• Байгаль орчныг хамгаалах: Ensure the inverter remains protected from direct exposure to harsh weather conditions like heavy rain or extreme temperatures.

8. Алдаа засах

If you encounter issues with your Y&H GMI-350W-110V micro inverter, consider the following common troubleshooting points:

• Цахилгаан гаралт байхгүй: Check if solar panels are receiving sufficient sunlight. Verify all DC and AC connections are secure. Ensure the solar panel voltage (Vmp) is within the inverter's MPPT range (24-42V) and the maximum input voltage (Voc) нь 60 В-оос ихгүй байна.
• Хэт халалт: If the inverter feels excessively hot, check for proper ventilation. Ensure it is installed in a cool, shaded area. Consider adding external fans to improve airflow around the unit, particularly around the bottom and sides where heat is dissipated.
• Инвертер асахгүй байна: Confirm that the solar panels are connected and producing power. Check the AC connection to the grid. The inverter requires grid power to operate (anti-islanding protection).
• Бага эрчим хүчний гаралт: This could be due to insufficient sunlight, shading on solar panels, or incorrect panel voltage/current. Ensure the solar panel power does not exceed the inverter's rated 350W.
• Inverter Status Light: Consult the product's specific LED indicator guide to diagnose issues based on the light's behavior.
