4. การตั้งค่าและการติดตั้ง

Before beginning installation, ensure all safety instructions are understood and followed. This section outlines the general steps for installing the micro-inverter.

4.1 รายการตรวจสอบก่อนการติดตั้ง

• Verify that the solar panels are compatible with the micro-inverter's input specifications (voltage และปัจจุบัน)
• Ensure the mounting location is suitable, providing adequate ventilation and protection from direct sunlight or extreme weather if not rated for it (though IP67 rated, optimal conditions prolong life).
• Gather all necessary tools and additional components (e.g., AC connection cable, mounting hardware).

4.2 Mounting the Micro-inverter

1. Attach the micro-inverter to the solar panel frame or a suitable mounting structure using appropriate hardware. Ensure it is securely fastened.
2. Position the micro-inverter to allow for proper cable management and air circulation around the cooling fins.

4.3 การเชื่อมต่อทางไฟฟ้า

1. การเชื่อมต่อ DC: Connect the DC cables from each solar panel to the corresponding DC input connectors on the micro-inverter. Ensure correct polarity (+ to + and - to -).
2. การเชื่อมต่อไฟฟ้ากระแสสลับ: Connect the integrated AC output cable of the micro-inverter to your AC grid connection point using a suitable AC cable (not supplied). Ensure the AC connection is properly grounded and protected by a circuit breaker.
3. หลายหน่วย: If installing multiple micro-inverters, connect their AC output cables in series to form an AC trunk cable, then connect to the grid. Refer to local electrical codes for maximum string length.

5. คู่มือการใช้งาน

Once installed, the Hoymiles HMS-1800-4T Micro-inverter operates largely automatically. This section details initial startup and monitoring.

5.1 การเริ่มต้นเริ่มต้น

1. After all electrical connections are secure, turn on the AC circuit breaker supplying power to the micro-inverter.
2. Next, ensure the solar panels are exposed to sufficient sunlight. The micro-inverter will automatically begin converting DC power from the panels to AC power for the grid once the input voltage reaches the startup threshold (22V).
3. Observe the indicator lights on the micro-inverter (if present) or use the monitoring system to confirm proper operation.

5.2 Monitoring with WiFi

The HMS-1800-4T includes integrated WiFi for remote monitoring. To utilize this feature:

• Download the Hoymiles monitoring application (e.g., S-Miles Cloud app) on your smartphone or access the web พอร์ทัล
