Installation Requirements & Safety Guidelines

Proper installation of your Deye hybrid inverter is critical to ensure long-term performance, safety, and compliance with Australian standards. As a high-capacity three phase inverter, this model is intended for commercial and industrial applications where careful planning and site readiness are essential.

Check Before You Begin

Before proceeding with installation, verify that the inverter package includes all components. Refer to the parts list provided in the documentation to confirm you’ve received every item. If anything is missing or damaged, contact your solar supplier before continuing.

Choosing the Right Location

To guarantee optimal performance and longevity, the Deye hybrid inverter should be installed in an environment that supports adequate airflow, protection from the elements, and safety compliance.

Installation site must meet the following conditions:

• Avoid direct sunlight, rainfall, or snow accumulation. Exposure to extreme weather can shorten the lifespan of your hybrid inverter.
• Do not install in areas with flammable materials or potential explosive atmospheres.
• Keep the inverter away from cold air vents to prevent internal condensation.
• Avoid locations near TV antennas or cables, as electromagnetic interference may affect communication.
• Ensure the inverter is not placed above 2000 metres in elevation.
• Do not install in environments with humidity greater than 95%.
• For ideal operation, ambient temperature should be maintained between -40°C and 60°C.
• Install the inverter at eye level for clear visibility of the LCD screen and LED indicators.
• The surface must be concrete or fire-resistant and capable of bearing the inverter’s weight.

Tip: Always allow 50 cm of clearance on all sides and at least 100 cm in front of the unit to promote natural heat dissipation. This prevents overheating and maintains inverter efficiency during heavy load cycles.

These precautions are essential, especially for solar inverters operating at high voltage and current levels.

Mounting the Inverter

Deye’s high-power three phase string inverter models are relatively heavy, so use proper lifting precautions. The wall-mounting process includes:

• Use a 62–70 mm drill bit to create 4 deep anchor holes in the mounting wall.
• Insert the expansion bolts into the holes and tighten the nuts after securing the metal mounting bracket.
• Hang the inverter onto the bracket and fix it with screws provided.
• Double-check alignment and make sure there’s no tilting beyond 15° in any direction, as improper angles may hinder cooling performance.

To protect your solar and inverter system’s integrity, only use the recommended installation tools, and ensure all installation steps comply with local building and electrical codes.

Additional Safety Notes

• Disconnect AC power first, then DC power, before performing any maintenance.
• Do not insert or remove connectors while the inverter is operating.
• The DC voltage must never exceed the inverter’s rated maximum.
• Only qualified electricians should handle installation and commissioning to avoid shock hazards or system damage.
• Keep all tools and accessories (expansion bolts, mounting brackets, communication ports) ready and organized before starting.

Whether you are a licensed solar installer or a system design engineer, following these installation guidelines ensures that the Deye hybrid inverter performs efficiently and safely in any large-scale solar products deployment. As one of the best solar inverters in Australia, Deye provides detailed manuals and mounting schematics to assist professionals in every step of deployment.
