Installation Location & Mounting Requirements

Proper installation of your three phase inverter is essential for ensuring safety, efficiency, and long-term reliability. The Deye SUN-3–12K-G05 Three Phase String Inverter is designed with versatility in mind but must be installed under specific guidelines to perform at its best—especially in the demanding Australian environment where solar inverters must handle high temperatures and fluctuating conditions.

Choosing the Right Installation Location

To get the most out of your Deye inverter and align with local safety regulations, always follow these guidelines when selecting an installation location:

• Avoid hazardous environments: Do not install the inverter in areas that contain flammable materials, explosive gases, or where electrical sparks may occur.
• Ensure airflow: This three phase inverter relies on natural cooling. Avoid enclosed or unventilated spaces where air circulation is restricted, as poor airflow may lead to overheating and reduced performance.
• Protect from direct sunlight: Continuous exposure to direct sunlight increases the inverter’s internal temperature, which may limit power output. Use shading or install in a naturally shaded area to keep operational temperature under 40°C (104°F).
• Mount securely: Install the inverter vertically on a strong, stable wall or structure that can bear the unit’s weight. It should not be inclined more than 15°, as improper tilt can obstruct heat dissipation.
• Maintain safe spacing: When installing multiple solar inverters, ensure at least 500 mm of clearance between each unit. This spacing is crucial for airflow and maintenance access. Always install the inverter in a location inaccessible to children or pets.
• User-friendly placement: Consider visibility of the LCD display and LED indicators when choosing the installation site. These displays offer vital information about inverter performance and system status, and should be easily accessible to the technician or property owner.

These precautions not only meet safety requirements but also maximize the inverter’s efficiency and service life, reinforcing why Deye continues to be regarded as one of the best solar inverters in Australia.

Installation Tools

The installation of this Three Phase String Inverter requires basic tools such as:

• Expansion bolts and drill (for mounting to brick or concrete walls)
• Spirit level (to ensure vertical placement within 15° inclination)
• Socket wrench and M4 screws (included in accessory pack)
• Electrical tools (for safe DC and AC connections)
• Optional: personal protective equipment, such as gloves and safety glasses

Additional auxiliary tools may be needed based on your site condition or mounting surface.
