Who Is This Inverter For?
The SUN-5K-SG04LP3-AU is a great fit if you:
- Have a 3-phase supply and want a neat solar-plus-battery solution
- Run a home with higher, spread-out loads (e.g. air-con, pumps, EV charger) on different phases
- Own a small workshop, café, office or shed on 3-phase looking to cut power bills
- Want to keep your options open – add batteries later or expand the system over time
Key Benefits of Deye 5 kW three-phase hybrid inverter
1. Made for 3-Phase Homes and Businesses
This inverter is three-phase from the ground up, with features like 100% unbalanced output – meaning each phase can supply up to 50% of the rated power when required.
What that means for you:
- Better suited to real-world 3-phase loads, where one phase often carries more than the others
- Less juggling which phase each circuit goes on – 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-5K-SG04LP3-AU manages:
- Solar panels (DC)
- A 48 V battery (charge and discharge)
- Grid connection, and in some designs, a generator
What that means for you:
- Daytime loads are powered by solar first
- Extra solar charges the battery
- At night, the battery can supply your loads before you import from the grid
- Everything is coordinated automatically in one unit
3. Flexible Roof Design with 2 MPPTs
From the AU technical data: 2 MPPT trackers with a maximum PV input of 7.5 kW and 10 kW max PV access power for this 5 kW model.
What that means for you:
- Panels can go on two different roof directions (e.g. north/east or north/west)
- Partial shade on one string is less likely to drag down the whole array
- There’s room to slightly oversize the PV array (within design rules) to improve performance in winter and overcast weather
4. Solid 48 V Battery Support
The series uses a 48 V low-voltage battery design (40–60 V), supporting both lead-acid and lithium-ion batteries with up to 120 A charge/discharge current on the 5 kW model.
What that means for you:
- Works with a wide range of common 48 V battery brands in Australia
- Enough current for a decent-sized battery bank, not just a token battery
- Safer low-voltage architecture that suits residential and small commercial installs
5. Smart Features and Room to Grow
The three-phase hybrid range offers:
- Six time periods for battery charging/discharging
- Ability to AC-couple with some existing solar systems
- Support for diesel generator integration in suitable designs
- Up to 16 inverters in parallel, on-grid or off-grid
What that means for you:
- Your system can be tuned to time-of-use tariffs – charge during solar/cheap periods, discharge in peak times
- You can keep a reserve for blackouts if you’re in an area with unreliable supply
- Clear upgrade path if you later add more load or want a bigger system
Monitoring & WiFi Plug
Australian sellers list this inverter as “5 kW 3 Phase Hybrid Inverter 48 V 2 MPPT WiFi Plug Included”, and the Deye spec shows WiFi, RS485 and CAN communications built in.
What that means for you:
- BSC Renewables can install it with the WiFi plug set up from the start
- You can see live solar production, battery level and grid import/export on your phone or laptop
- Easier remote support if something needs checking down the track
