Deye Single Phase String Inverter 7.5 kW or 9 kW

Deye offers a 10-year limited warranty on the SUN-3.6/5/6K-G04-AU inverter series in Australia. This means you get a full manufacturer’s warranty covering parts and labor for ten years, reflecting Deye’s confidence in the product’s durability. Always register your inverter with Deye (if required) and keep proof of purchase to ensure the warranty is in effect. Local support through Deye’s Australian offices and distributors makes any warranty claim straightforward.

Yes. While the Deye Single Phase String Inverter is primarily an on-grid solar inverter (not a hybrid with built-in battery inputs), it can certainly be used in conjunction with battery storage. For example, you can pair it with an AC-coupled battery system (including Deye’s own battery solutions or other brands like AlphaESS) to store excess solar energy. In practice, this means the inverter will handle your PV generation and feed into your home and grid, and a separate battery inverter or AC battery unit will charge/discharge the battery. If you prefer an all-in-one unit, Deye also offers hybrid inverters specifically designed for direct battery integration.

Zero-export: Yes, this inverter supports zero-export functionality. It can be configured with an export power limit (using an external CT sensor and settings) to ensure no excess solar power is sent to the grid – useful for installations where the utility or network provider requires zero feed-in.
VPP: While the SUN-G04 single phase inverter itself doesn’t have dedicated VPP software, it is compatible with virtual power plant programs when paired with appropriate equipment. Many VPP schemes in Australia involve a smart controller or a battery system; if you integrate the Deye inverter into such a setup (for example, alongside a Deye or AlphaESS battery that is VPP-enabled), it can participate in a VPP. The inverter’s communication interfaces (RS485/CAN/WiFi) allow it to be monitored and controlled by energy management systems, making it possible to use in VPP or demand response programs as those services become available from your energy retailer.

Absolutely – the Deye single phase inverter is designed for the Australian market and fully complies with Australian grid standards. The model carries accreditation to AS/NZS 4777.2:2020, which is the standard for grid-tie inverters in Australia, as well as AS/NZS 3100 for electrical safety.
Additionally, the inverter has an IP65 outdoor rating and meets all relevant EMC and safety standards (IEC 62109, etc.), so it’s suitable for the harsh Australian climate and strict regulations. In short, it is perfectly suited for Australian residential installations and you can install it with confidence that it meets all requirements of local distributors and authorities.

The Deye 7.5 kW/9 kW (5 kW/6 kW output) single phase inverter should be installed by a licensed solar installer following all local electrical codes. Here are some key requirements and considerations:
1. System Size: As a single-phase unit, it’s ideal for homes with single-phase power. It can be installed on a property with three-phase power as well, but it will only supply one phase – in such cases, you might use multiple inverters or limit export as needed by your network provider. Most Australian utilities allow up to 5 kW per phase for solar export without special approval, so if you install the 6 kW model, you may need to enable the inverter’s export limit setting to 5 kW (which it supports).
2. Panel Array Sizing: The 5 kW inverter can take up to 7.5 kW of solar panels, and the 6 kW inverter can take up to 9 kW of panels (DC input). This 150% DC oversizing capability is within Australian Clean Energy Council guidelines and helps maximize energy production. Ensure your panel strings’ voltage stays within the 70–500 V MPPT window and does not exceed 550 V open-circuit.
3. Mounting Location: The inverter is rated IP65 (weatherproof), so it can be mounted outdoors or indoors. It should be placed in a shaded, well-ventilated area to avoid direct sun and high heat, which will prolong its lifespan and maintain efficiency (it will derate above 45 °C). Keep at least 30 cm of clearance around it for airflow, as it uses passive cooling.
4. Installation and Wiring: Follow the Installation Manual closely. DC input is via MC4 connectors, and AC output must be wired to your switchboard by an electrician. A separate DC isolator is required next to the unit (per Australian standards). Also, the inverter must be set up with the correct grid profile (it will have an Australia default setting for 50 Hz, etc., which your installer will confirm).
In summary, there are no unusual limitations – just standard practices. A certified installer will ensure the Deye inverter is installed safely, in compliance with all rules, and performing optimally for your solar and battery system.
