1-Phase 12 kW Hybrid Inverter (48 V, 3 MPPT, WiFi Plug Included)
The SUN-12K-SG02LP1-AU-AM3 is a 12 kW single-phase hybrid inverter designed for big homes and light commercial sites that want serious solar and battery capacity without moving to three-phase power. It brings solar, 48 V battery and grid into one smart unit, with three MPPTs and strong battery performance for larger storage setups.
BSC Renewables can supply, install and commission this inverter as part of a complete solar-plus-battery system, with the WiFi plug included and configured so monitoring works from day one.

- Can take up to 18 kW of PV input, with PV access power up to 24 kW (DC oversizing)
- Up to 16 inverters in parallel, on-grid or off-grid
- 6 time periods for battery charge/discharge scheduling
- IP65, –40 to +60 °C, up to 100% humidity, <45 dB noise
- AS/NZS 4777.2 compliant and CEC-approved for use in Australia, with a 10-year warranty.
Who Is This Inverter For?
The SUN-12K-SG02LP1-AU-AM3 is a strong fit if you:
- Have a large home with plenty running at once – ducted air-con, pool, EV charger, multiple fridges, big kitchen appliances
- Run a home-based business or light commercial site on single-phase power
- Want meaningful battery backup and the ability to add more storage over time
- Plan to keep growing your system – more panels, extra batteries or even multiple inverters in parallel
Key Benefits of 12 kW single-phase hybrid inverter
1. Big Single-Phase Power (12 kW)
The Deye spec lists 12,000 W rated AC power and up to 52.2 A output on a single phase.
What that means for you:
- Much more headroom than a typical 5–6 kW system
- Better suited when “everything’s on at once” – air-con, pool pump, EV charger, home office, etc.
- A stronger platform for backup loads, when designed with a backup circuit and battery bank
2. High-Current 48 V Battery Support
According to the official AU data, the SUN-12K supports:
- Battery type: lead-acid or lithium (incl. LiFePO₄)
- Battery voltage range: 40–60 V
- Max charging current: 250 A
- Max discharging current: 250 A
What that means for you:
- Built for larger 48 V battery banks, not just a token bit of storage
- Faster charging from solar on good days
- More muscle to keep key loads running longer during an outage (when paired with an appropriately sized battery and backup circuit)
3. Three MPPTs and Heaps of Solar on the Roof
SUN-12K offers:
- 3 MPPTs, with 2 strings per tracker (2+2+2)
- Max PV input power: 18,000 W
- Max PV access power (oversizing): 24,000 W
- MPPT voltage range 150–425 V
What that means for you:
- Panels can be split across multiple roof faces – north, east, west, sheds or extensions
- Shaded or awkward areas can be isolated on their own tracker so they don’t drag the rest down
- Plenty of capacity to slightly oversize the array to improve winter and cloudy-day performance (within design and compliance limits)
4. Smart Operation & Future-Ready Design
Deye offers several “brains” features for the SUN-10/12K-SG02LP1-AU-AM3:
- 6 programmable time periods for battery charging and discharging
- AC-coupling options to work alongside some existing solar systems
- Supports storing energy from a diesel generator (where a gen set’s part of the design)
- Max 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 mostly from solar and cheaper periods, discharge during the expensive times
- You can keep a battery reserve for blackouts if you’re in a dodgy supply area
- There’s a clear upgrade path if you extend the home or business and need more capacity later
5. Built for Aussie Conditions
It’s designed to withstand harsh Aussie weather:
- Outdoor-rated (IP65) for wall mounting
- Operating temperature –40 to +60 °C (with derating above 45 °C)
- Humidity 0–100%, altitude up to 2,000 m
- Noise <45 dB
- AS/NZS 4777.2 compliant, with a 10-year warranty
What that means for you:
- Well suited to Aussie back walls, garages and meter areas
- Designed and tested for long-term operation in local conditions when installed by a licensed solar electrician
Monitoring & WiFi Plug
The Deye hybrid range supports WiFi communication, with RS485 and CAN on board for monitoring and integration.
What that means for you:
- BSC Renewables can supply the unit with the WiFi plug included and set up
- You can check live solar production, battery state and grid import/export from your phone or laptop
- Easier remote support if something ever needs checking or tweaking
- BSC Renewables can supply the unit with the WiFi plug included and set up
