3-Phase 8 kW Hybrid Inverter (48 V, 2 MPPT, WiFi Plug Included)
The SUN-8K-SG04LP3-AU is an 8 kW three-phase hybrid inverter designed for medium to large homes and small businesses on 3-phase power. It brings together solar, a 48 V battery and the grid in one unit, with two MPPTs for flexible panel layouts and a WiFi plug so you can keep an eye on everything from your phone.
BSC Renewables can supply, install and commission this inverter as part of a complete solar-plus-battery system tailored to your place.
At a Glance

- 100% unbalanced output – can deliver up to 50% of rated power on a single phase when needed
- Can AC-couple to existing solar and work with a diesel generator in suitable designs
- Up to 16 inverters in parallel, on-grid or off-grid
- CEC-approved and compliant with AS/NZS 4777.2, with a 10-year warranty
- 8 kW three-phase hybrid inverter – for 3-phase homes and small businesses
Who Is This Inverter For?
The SUN-8K-SG04LP3-AU is a great fit if you:
- Have a 3-phase home with higher usage – ducted air-con, pool, pumps, EV charging, home office gear
- Run a small business, workshop, café or office on 3-phase power
- Want to add a 48 V battery now or later for better bill savings and backup
- Plan to grow over time – more panels, more storage, or even parallel inverters down the track
Key Benefits of Deye 8 kW three-phase hybrid inverter
1. Built Properly for 3-Phase Properties
This is a true three-phase hybrid inverter with support for 100% unbalanced output – each phase can deliver up to half the rated power.
What that means for you:
- Better suited to real-world homes and businesses where one phase often carries more load
- Less fuss about which circuits sit on which phase – the inverter is designed to handle uneven demand
2. Hybrid: Solar, Battery and Grid in One Box
Like the rest of the Deye hybrid range, the SUN-8K-SG04LP3-AU controls:
- Solar panels – converting DC into usable AC
- A 48 V battery – charging during the day and discharging when needed
- The grid connection – importing when you’re short, exporting when there’s surplus
What that means for you:
- Daytime loads run on solar first
- Extra solar fills the battery (within the 40–60 V range and up to 190 A)
- At night or during cloudy spells, the battery can supply your loads before the grid kicks in
It’s all managed automatically – you just see the bill savings.
3. Flexible Panel Layout with 2 MPPTs
From the AU technical specs: this model uses two independent MPPT trackers, with:
- Up to 12,000 W of PV input
- Up to 16,000 W max PV access (DC oversizing)
- MPPT window roughly 200–650 V
What that means for you:
- Panels can go on two different roof faces (for example north/east or north/west)
- Shaded or awkward areas can be kept on their own string to reduce impact on the rest
- There’s room to slightly oversize the array (within design rules), helping winter and cloudy-day performance
4. Strong, Safe 48 V Battery Support
Deye lists this series as a low-voltage (48 V) hybrid, with:
- 48 V battery (40–60 V range)
- Lead-acid or lithium-ion support
- Up to 190 A charging and discharging for the 8 kW model
- “Self-adaption to BMS” for lithium batteries
What that means for you:
- Works with a wide range of 48 V battery brands used in Australia
- Plenty of current for a decent-sized battery bank, not just a small add-on
- Low-voltage architecture that’s well suited to residential and small commercial installs
5. Smart Features and Room to Grow
According to Deye’s AU site and user manual, the SUN-5/6/8/10/12K-SG04LP3-AU series includes:
- Six programmable time periods for battery charging/discharging
- Ability to AC-couple to some existing solar systems
- Support for storing energy from a diesel generator in suitable designs
- Parallel operation up to 16 inverters, on-grid or off-grid
What that means for you:
- Your system can be tuned to time-of-use tariffs – charging in cheap/solar periods and discharging during peak rates
- You can keep a reserve in the battery for blackouts if needed
- There’s a clear upgrade path if your energy use grows over time
6. Monitoring & WiFi Plug
This model is a three-phase hybrid inverter with WiFi included, plus RS485/CAN communications.
What that means for you:
- BSC Renewables can set up the WiFi plug during installation
- You can view live solar production, battery level and grid import/export from your phone or laptop
- Remote data (where available) makes support and troubleshooting easier if something doesn’t look right
