1-Phase 6 kW Hybrid Inverter (48 V, 2 MPPT, WiFi-Ready)
The Deye SUN-6K-SG04LP1-AU is a 6 kW single-phase hybrid inverter designed for Australian homes and small businesses that want a bit more grunt than a standard 5 kW system. It manages solar, batteries and the grid in one unit and is approved to AS/NZS 4777.2 and listed as CEC-approved for use in Australia.
BSC Renewables can design and install a complete solar-plus-battery system around this inverter, supplying it with a WiFi plug included and set up so you can monitor your system from day one.

Who Is This Inverter For?
The SUN-6K-SG04LP1-AU is a great fit if you:
- Have a larger home or high daytime usage (pools, ducted air-con, EV charging, home office).
- Run a small business or commercial tenancy on single-phase supply and want strong backup and export capacity.
- Want to maximise self-consumption with room to expand your solar array and battery over time.
It gives a bit more breathing room than a 5 kW unit, without jumping all the way to a three-phase system.
Key Benefits of Deye SUN-6K-SG04LP1-AU
1. Solar, Battery and Grid in One Box
As a hybrid inverter, the SUN-6K-SG04LP1-AU handles:
- Solar panels – convert DC from your array to usable AC.
- Battery – charge from solar (and in some modes, the grid or generator).
- Grid connection – import when needed, export when allowed.
What does this mean for you:
- During the day, solar runs your loads first.
- Extra solar charges the battery up to the 135 A limit.
- After sunset, the battery can supply up to 6 kW of power before you draw from the grid.
This helps cut power bills and makes better use of the solar you generate.
2. Strong 48 V Battery Performance
From the official spec sheet:
- Battery type: lead-acid or lithium-ion
- Battery voltage range: 40–60 V
- Max charge current: 135 A
- Max discharge current: 135 A
- Battery inputs: 1
What that means for your system:
- Works with a wide range of popular 48 V battery brands used in Australia.
- High charge and discharge current supports faster charging and strong backup power for larger loads.
- Low-voltage battery architecture is well suited to homes and small businesses from a safety and design point of view.
3. More Roof Flexibility with Dual MPPTs
On the solar side, the inverter offers:
- 2 independent MPPT trackers
- Max PV access power: 12,000 W
- Max PV input power: 9,000 W
- MPPT voltage range: 150–425 V
- Max operating PV input current: 13 + 13 A
- Max short-circuit current: 19.5 + 19.5 A
- Strings: 2 (1+1)
This lets BSC Renewables:
- Split panels across two roof orientations (e.g. north/east, north/west).
- Design around partial shade by separating strings.
- Slightly oversize the array so you still get good output in less-than-perfect conditions.
4. Smart Time-of-Use Style Control
The Deye hybrid series supports six separate time periods for battery charging and discharging.
This is useful for:
- Time-of-use tariffs – charge mostly from solar and cheap periods, discharge during peak rates.
- Load shifting – keep expensive evening usage mostly on the battery.
BSC Renewables can set these schedules up to match your tariff and routine.
5. Scalable for Bigger Systems
The SUN-3/3.6/5/6K-SG04LP1-AU range supports up to 16 inverters in parallel for both on-grid and off-grid systems.
That means you can:
- Start with one 6 kW inverter now.
- Add more units later if you extend your home, add more air-con, or expand a business site.
6. Built for Australian Conditions
Deye’s hybrid inverter models in Australia offer:
- Operating temperature: –40 °C to +60 °C (with derating above 45 °C)
- Protection rating: IP65 – suitable for outdoor wall mounting
- Noise level: <30 dB
- Altitude: up to 2,000 m
- Grid regulation: AS/NZS 4777.2
- Safety/EMC: IEC/EN 61000-6-1/2/3/4, IEC/EN 62109-1, IEC/EN 62109-2
So it’s well matched to typical Australian weather and compliance requirements when installed by a licensed solar electrician.
7. Monitoring, WiFi Plug and Connectivity
Specs include:
- Communication interfaces: WiFi, RS485, CAN
- Monitoring options: WiFi, GPRS, Bluetooth, 4G, LAN (via Deye’s ecosystem)
- Front LCD display and status indicators
It comes with plug-in WiFi module used for app monitoring. BSC Renewables can supply and configure the WiFi plug as part of your installation, so you can:
- Check solar production and battery state from your phone.
- See how much you’re importing and exporting.
- Make remote support and troubleshooting easier if needed.
8. Safety and Protection
The SUN-6K-SG04LP1-AU includes a comprehensive protection suite, including:
- DC reverse polarity protection
- AC output over-current and over-voltage protection
- AC output short-circuit protection
- Thermal protection
- DC component monitoring
- Insulation impedance detection and residual-current monitoring
- Ground-fault and earth-fault detection
- Surge protection (Type II on DC and AC)
- DC input switch
- Anti-islanding protection with active frequency shift
These help protect your equipment, your property and the grid, provided the system is installed correctly.
