12 kW Three-Phase High-Voltage Hybrid (160–700 V, 2 MPPT, WiFi Plug Included)
The SUN-12K-SG01HP3-AU-AM2 is a 12 kW three-phase high-voltage hybrid inverter built for bigger homes and light commercial sites that want serious solar plus batteries on 3-phase power. It works with a 160–700 V lithium battery, your solar array and the grid, all through one smart unit.
BSC Renewables can design a complete system around this inverter – panels, battery, monitoring and grid connection – so everything plays nicely together from day one.
At a Glance
Here’s what you get when you choose Deye 12 kW three-phase high-voltage hybrid inverter:
- 12 kW three-phase hybrid inverter – sized for large homes and small commercial installs
- High-voltage battery input (160–700 V) for higher efficiency and lower losses
- Dual MPPTs (2 MPPT / 2 strings total) for splitting panels across different parts of the roof
- Designed for 100% three-phase unbalanced output – a single phase can carry up to half the rated power when required
- Parallel-ready – can run alongside multiple SUN-xK-SG01HP3 units for larger systems (on-grid or off-grid)
- CEC-approved high-voltage hybrid for the Australian market
- WiFi plug included, with monitoring via Deye’s cloud platform
When this inverter is a good fit
The SUN-12K-SG01HP3-AU-AM2 tends to suit you if:
- You’ve got a 3-phase supply and decent loads – ducted air, pool or spa, EV charger, pumps, workshop gear
- Your place is a bit bigger than average, or you’re running a small commercial site or busy home office off the same supply
- You’re leaning towards a high-voltage battery rather than a traditional 48 V bank
- You’d like room to move later – more panels, more storage or even additional inverters in parallel
Key Benefits of Deye 12 kW three-phase high-voltage hybrid inverter
1.High-voltage battery
Unlike the low-voltage (48 V) hybrids, this Deye range is built around a 160–700 V lithium battery input.
What that gives you:
- Better round-trip efficiency – less wasted as heat in the cables and electronics
- Lower current on the battery side, so the wiring run is usually neater and less chunky
- A good match to modern modular HV battery stacks that are designed to sit in this voltage window
If you’re chasing long-term efficiency and a clean install, HV storage is worth the step up.
2.Plays nicely with real-world 3-phase loads
On paper, loads are perfectly balanced. In real houses and businesses, they’re not.
This inverter supports 100% unbalanced three-phase output, which means:
- Any single phase can deliver up to 50% of the unit’s rated power
- The system can handle one phase doing more work – for example the phase with the EV charger or big air-con
- You don’t have to obsess about perfectly even phase loading when circuits are added over time
It’s built for the messy reality of Aussie switchboards, not just lab conditions.
3. Solar design: two MPPTs and plenty of DC
From the Deye AU datasheet for the SUN-5–25K-SG01HP3-AU-AM2 series:
- 2 MPPTs, each with its own string
- High PV input capacity relative to the 12 kW AC rating (DC oversizing supported within limits)
In practice, that lets BSC Renewables:
- Put one MPPT on your best orientation (often north), and the other on east/west, shed or extension
- Keep shadier sections of roof isolated so they don’t drag down the whole array
- Add a bit more panel capacity than 12 kW AC so the system still punches on in winter and cloudy weather (within design and compliance rules)
4. Smarter energy use & future-proofing
From Deye’s own documentation on the HP3 series:
- You can set up to six different time windows for battery charge and discharge
- The inverter can AC-couple to some existing solar systems, handy if you’re retrofitting batteries
- It supports storing energy from a diesel generator in the right design
- Multiple units can be run in parallel for bigger jobs
For you, that translates to:
- Lining the system up with time-of-use tariffs – charging mostly from solar and off-peak, discharging in peak periods
- The option to keep some battery in reserve for blackouts rather than emptying it every night
- A clear upgrade path if you add a shed, extend the house or grow the business and need more capacity
5. Monitoring and the WiFi plug
Australian suppliers list this model as a 3-phase 12 kW high-voltage hybrid with WiFi plug included, and the Deye docs confirm WiFi, RS485 and CAN comms.
What that means day to day:
- BSC Renewables can set up the WiFi monitoring during installation
- You can jump into the app to see:
- How much solar you’re making
- What the battery’s doing
- How much you’re importing from or exporting to the grid
- How much solar you’re making
- Remote data (where available) makes it easier to spot issues early and fine-tune settings over time
- BSC Renewables can set up the WiFi monitoring during installation
