The Deye SUN-20K-SG05LP3-EU is a 20 kW three-phase hybrid inverter that runs on a 48 V low-voltage (LV) battery. It offers up to 350 A charge/discharge current, 2 MPPTs and 97.6% maximum efficiency, making it a strong choice for large homes and businesses on a three-phase supply that want to use 48 V batteries.
Key features
- 20 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 350 A charge/discharge current: fast battery charging and enough current for heavy loads.
- 2 MPPT inputs with a 160-650 V MPPT range: strings on different orientations and tilts are optimised separately.
- 97.6% maximum conversion efficiency.
- Unbalanced output on each phase: a single phase can carry up to 50% of rated power.
- 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

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 is the difference between HV and LV batteries?
HV (high-voltage) batteries run at hundreds of volts, so the same power needs less current, thinner cables and loses less heat, which suits larger systems. LV (48 V) systems are common at household scale, easy to expand and cost-effective.
Can several inverters run in parallel?
Yes. Up to 10 inverters of the same model can run in parallel in on-grid and off-grid mode, so power can be added later without replacing the existing system.
How much battery does a 20 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.
