1. Introduction

On-grid inverters convert solar panel DC power into AC power for direct grid input. This manual provides essential information for safe and effective use.

2. Safety Warnings and Instructions

Improper use can lead to electric shock or burns. This manual contains crucial safety instructions for installation and maintenance. Always read and follow these guidelines carefully.

• Warning: Indicates important safety instructions; failure to comply may result in serious injury or death.
• Shock Hazard: Highlights risks of electric shock; non-compliance can lead to electric shock.
• Safety Hint: Provides important safety notes; incorrect adherence may cause damage or destruction of the inverter.
• High Temperature Hazard: Warns of hot surfaces; failure to follow instructions may result in burns.

Key Safety Instructions:

• Electrical installation must comply with local safety regulations.
• Ensure DC input and AC output are electrically isolated before operation.
• Do not disassemble the inverter case; repairs should be performed by qualified personnel.
• When PV modules are exposed to sunlight, they generate DC voltage. Avoid touching to prevent shock.
• Wait at least 5 minutes after disconnecting power for the inverter to discharge residual electricity.
• Inverter surface temperature may exceed 80°C during operation; avoid touching.
• All electrical installations must adhere to local electrical standards and obtain permission from the local power company.
• Use anti-static measures during installation.
• Install the inverter in a location inaccessible to children.

3. Operation Interface

The inverter features an operation interface with a display screen and control buttons (Up, Down, ESC, Enter) for navigation and parameter adjustment. The status indicators (DC, AC, NORMAL, ALARM) provide real-time operational feedback.

4. Product Installation

Proper installation is crucial for optimal performance and safety. Key considerations include:

• Installation Location: Avoid areas with flammable materials, explosive atmospheres, or poor ventilation. Ensure adequate airflow around the unit. Protect from direct sunlight and rain to prevent overheating and power limiting. Ambient temperature should be considered, with a sun shade recommended if temperatures exceed 40°C (104°F).
• Mounting: Install on a strong, load-bearing structure. Mount vertically with a maximum incline of +/-15°. Maintain a minimum gap of 500mm between inverters and 500mm above and below each unit. Ensure the display and indicators are clearly visible.
• Ventilation: Provide a well-ventilated environment, especially if installed in an airtight space.
• Clearance: Do not place items next to the inverter.

Refer to the diagrams for recommended installation locations, angles, and spacing.
