Power your home with smarter, safer solar.

Meet the Deye 3.6kW On-Grid Single-Phase String Inverter a 3.6kW single-phase string inverter engineered to squeeze every last watt out of your rooftop. With dual MPP trackers and a maximum efficiency of 97.5%, this compact powerhouse turns sunshine into serious savings, day after day.

Why you’ll love it

Higher yields, every day

Two independent MPP trackers and an MPPT efficiency of over 99% mean your panels work harder and smarter, even when conditions aren’t perfect. A remarkably low start-up voltage of just 80V gets your system generating earlier in the morning and later into the evening, extending your productive hours.

Safe & reliable

Built with safety at its core, the inverter features an optional Anti-PID function to protect long-term performance and zero-export capability to keep you in control of what flows back to the grid. It’s protection you can count on, season after season.

Smart & connected

Stay in the know with optional string intelligent monitoring and VSG (Virtual Synchronous Generator) application support giving you grid-friendly performance and real-time insight into your energy production right at your fingertips.

User-friendly by design

At just 8kg and a slim 330 × 323 × 190mm, installation is refreshingly simple. A wide output voltage range ensures stable, flexible operation across varied grid conditions, and an IP65 enclosure with natural cooling means quiet, maintenance-free operation indoors or out.

Technical Snapshot

The bottom line

Blending high efficiency, robust safety, and genuinely user-friendly features, the Deye SUN-3.6K-G04-AU is the smart choice for residential solar whether you are cutting your power bills or stepping toward energy independence. This inverter delivers reliable, intelligent performance you can trust for years to come.

What is the Deye SUN-3.6K-G04-AU inverter?
The Deye SUN-3.6K-G04-AU is a 3.6kW single-phase on-grid string inverter that converts DC power from rooftop solar panels into AC power for your home and the grid. It has two MPPT trackers, a 97.5% maximum efficiency, an 80V start-up voltage and an IP65 enclosure, and weighs just 8kg. It suits NZ homes installing a grid-connected solar system to cut power bills.

What is the difference between an on-grid string inverter and a hybrid inverter?
An on-grid string inverter like the Deye SUN-3.6K-G04-AU converts solar power for use in your home and sends surplus to the grid, but doesn’t manage battery storage. A hybrid inverter does the same job and also charges and discharges a battery. If you want battery storage now, the Deye SUN-3.6K-SG04LP1-AU 3.6kW single-phase hybrid inverter is the equivalent hybrid model.

Can I connect a battery to the Deye SUN-3.6K-G04-AU?
No, the Deye SUN-3.6K-G04-AU is a grid-tied string inverter with no battery input. To add storage later, a Deye hybrid inverter with AC-coupling can retrofit a battery onto your existing solar system without replacing this inverter.

Does the Deye 3.6kW on-grid inverter work during a power cut?
No, grid-tied inverters like the Deye 3.6kW on-grid inverter shut down automatically during a grid outage as a safety requirement, so your solar won’t power the home while the grid is down. For backup power during outages, a hybrid inverter with battery storage is needed.

How much solar can I connect to the Deye SUN-3.6K-G04-AU?
The Deye SUN-3.6K-G04-AU accepts up to 5.4kW of solar PV input, a 1.5× ratio to its 3.6kW AC output. Panels connect across two MPPT trackers with one string each, within a 70–500V MPPT voltage range and a 550V maximum PV input voltage.

Why do two MPPT trackers matter on a 3.6kW inverter?
Two independent MPPT trackers let the Deye SUN-3.6K-G04-AU optimise two panel strings separately. That’s useful when panels face different directions, sit at different tilts or get partial shade, because one weaker string doesn’t pull down the other. MPPT efficiency is above 99%.

What does the 80V start-up voltage mean?
The Deye SUN-3.6K-G04-AU begins generating once panel voltage reaches just 80V. Your system starts producing power earlier in the morning and keeps going later into the evening, extending productive hours each day.

Does the Deye SUN-3.6K-G04-AU support zero export?
Yes, the Deye SUN-3.6K-G04-AU has zero-export capability, letting you limit or stop the solar power sent back to the grid. That’s useful where your network operator restricts or doesn’t permit export.

What safety and monitoring features does the Deye 3.6kW string inverter have?
The Deye 3.6kW string inverter offers an optional Anti-PID function to protect long-term panel performance, optional string-level intelligent monitoring, and support for VSG (Virtual Synchronous Generator) applications for grid-friendly operation.

How efficient is the Deye SUN-3.6K-G04-AU?
The Deye SUN-3.6K-G04-AU has a maximum efficiency of 97.5%, a Euro efficiency of 97.0% and an MPPT efficiency above 99%. Very little of your panels’ output is lost converting it to usable AC power.

What is the AC output of the Deye SUN-3.6K-G04-AU?
The Deye SUN-3.6K-G04-AU delivers 3.6kW of rated AC output power and up to 3.96kVA of maximum apparent power on a single-phase 230V supply. A wide output voltage range keeps operation stable across varying grid conditions.

Can the Deye 3.6kW on-grid inverter be installed outdoors?
Yes, the Deye 3.6kW on-grid inverter has an IP65-rated enclosure, so it can be installed indoors or outdoors. It uses natural cooling with no fans, which means quiet, low-maintenance operation.

How big and heavy is the Deye SUN-3.6K-G04-AU?
The Deye SUN-3.6K-G04-AU weighs 8kg and measures 330 × 323 × 190mm, making it light and compact enough for a simple wall-mount installation.
