Who Is This Inverter For?
The SUN-15K-SG05LP3-AU-SM2 is a great match if you:
- Have a 3-phase home with big loads ducted air-con, pool, spa, EV charger, multiple fridges, big kitchen gear
- Run a small commercial site, workshop, café or office on 3-phase power
- Want meaningful battery storage for bill reduction and backup, not just a small add-on
- Expect your usage to grow over time and want an inverter platform that can scale with you
Key Benefits of 15 kW three-phase hybrid inverter
1. Serious Three-Phase Power (15 kW)
This model delivers 15,000 W of AC power across three phases, with the ability to run heavily unbalanced loads (each phase can provide up to 50% of rated power).
What that means for you:
- Plenty of headroom when the house or site is “all on at once”
- Well suited to larger homes and small commercial sites with mixed loads across phases
- A strong base for backup circuits when paired with the right battery setup
2. Built for Big 48 V Battery Banks
Deye specifies a 48 V low-voltage battery (40–60 V) with 280 A max charge and discharge current on the SUN-15K model.
What that means for you:
- Supports larger 48 V battery banks for meaningful overnight coverage
- High current allows fast charging from solar on good days
- More muscle to keep key loads running in a blackout (when designed with an appropriate battery and backup load panel)
3. Two MPPTs and Plenty of Solar on the Roof
For PV, the AU datasheet lists for the 15 kW model:
- Max PV input power: 24,000 W
- Max PV access power: 30,000 W (DC oversizing)
- 2 MPPTs / 2 strings each, MPPT range 160–650 V
What that means for you:
- Panels can be split across two main roof orientations (north/east, north/west, house + shed, etc.)
- Shaded or awkward areas can be isolated so they don’t drag down the entire array
- There’s room to sensibly oversize the array (within design rules), which helps winter output and performance on cloudy days
4. Smart Energy Management & Flexible Design
From Deye’s AU site and series documentation:
- Six programmable time periods for battery charging and discharging
- Ability to AC-couple to some existing solar systems
- Supports storing energy from a diesel generator in suitable designs
- Up to 10 inverters in parallel for larger systems
What that means for you:
- Your system can be tuned to time-of-use tariffs charge mostly from solar and off-peak, discharge in peak times
- You can keep a battery reserve for outages if your area has unreliable supply
- There’s a clear upgrade path if your home or business grows and you need more capacity later
5. Designed for Aussie Conditions
- IP65 outdoor rating suited to external walls and meter areas
- Operating temperature –40 °C to +60 °C (with derating at higher temps)
- High conversion efficiency (max 97.6%, MPPT efficiency >99%)
- Compliant with AS/NZS 4777.2, with a 10-year warranty
What that means for you:
- Designed and approved for Australian conditions when installed by a licensed solar electrician
- A reliable long-term backbone for your solar and battery system, not a stop-gap solution
6. Monitoring & WiFi Plug
This three-phase hybrid inverter comes with WiFi monitoring and RS485/CAN communications.
What that means for you:
- BSC Renewables can install it with the WiFi plug set up from day one
- You can check live solar production, battery level and grid import/export from your phone or laptop
- Remote data (where available) makes it easier to troubleshoot and fine-tune the system over time
