The Deye SUN-12K-SG04LP3-EU is a 12 kW three-phase hybrid inverter that runs on a 48 V low-voltage (LV) battery. It offers up to 240 A charge/discharge current, 2 MPPTs and 97.6% maximum efficiency, and its unbalanced phase output supplies home and business loads that are not spread evenly across phases.
Key features
- 12 kW rated output, three-phase grid connection.
- 48 V low-voltage (LV) battery system (40-60 V): works with lithium (LiFePO₄) and lead-acid batteries.
- Up to 240 A charge/discharge current: fast battery charging and enough current for heavy loads.
- Unbalanced output on each phase: a single phase can carry up to 50% of rated power.
- 2 MPPT inputs with a 200-650 V MPPT range: strings on different orientations and tilts are optimised separately.
- 97.6% maximum conversion efficiency.
- Up to 10 units in parallel, on-grid and off-grid, so the system can grow with demand.
- Diesel generator input: the generator takes over when the grid is down and can also charge the battery.
- IP65 protection: dust- and water-protected wall-mounted enclosure suitable for outdoor use.
Where it is used
- Large villas on a three-phase supply
- Offices, shops and small businesses
- Farms, barns and agricultural buildings
- Rooftop solar plants with storage
Installation with Aden Solar
Aden Solar calculates inverter power and battery capacity from your consumption profile, typical outage length and the critical loads you want covered. We deliver turnkey installation: free site survey, string design, switchboard and cabling, installation, grid connection, monitoring setup and commissioning.
Frequently asked questions
What is a hybrid inverter?
A hybrid inverter manages energy flow between solar panels, the grid and a battery in one device. Generation feeds the loads first, the surplus charges the battery, and critical loads keep running from the battery during an outage.
What does unbalanced output mean?
In real buildings, loads are never spread evenly across three phases. An inverter with unbalanced output supplies each phase according to its own demand, so heavy use on one phase is covered even when the others are lightly loaded.
Should I choose a single-phase or three-phase inverter?
It depends on your grid connection and loads. Single-phase supplies use a single-phase inverter; three-phase supplies and three-phase motors, pumps or compressors need a three-phase inverter. Aden Solar checks your connection during the survey.
How much battery does a 12 kW inverter need?
It depends on how many hours and which loads you want covered during an outage. Aden Solar lists the critical loads during the site survey, reviews your daily consumption and calculates the required kWh in writing.
