Choose the SUN-6K-SG03LP1-EU when a single-phase site needs 6 kW of AC power and a 135 A battery current. If 5 kW is enough, the SUN-5K-SG03LP1-EU fits. If you connect to three phases, look at the SUN-5K-SG04LP3-EU (5 kW) or the SUN-8K-SG04LP3-EU (8 kW, 190 A battery current).
What is a 6 kW single-phase hybrid inverter used for?
The Deye SUN-6K-SG03LP1-EU is built for single-phase systems with 6 kW of AC power: home solar systems with batteries, backup power, off-grid (island) systems and adding storage to an existing solar system through AC coupling. The Time of Use function helps optimise energy consumption.
Hybrid inverter with battery: which batteries are compatible?
The Deye SUN-6K-SG03LP1-EU connects to 40–60 V batteries, either lead-acid or lithium-ion; for Li-ion the charging strategy adapts to the battery’s BMS. It has one battery input and a maximum charge / discharge current of 135 A.
- Several batteries can be connected in parallel.
- Up to 16 inverters can run in parallel, in both grid-connected and off-grid mode.
- You can programme 6 time periods for when the battery charges and discharges.
How to size a solar inverter: power and PV input
The Deye SUN-6K-SG03LP1-EU has 6 kW rated AC power and 6,600 VA maximum AC apparent power. In off-grid mode it can deliver twice its rated power for 10 s. Two PV figures are easy to mix up:
- Max. PV access power: 12,000 W.
- Max. PV input power: 7,800 W.
- MPPT voltage range: 150–425 V, maximum PV input voltage 500 V, start-up voltage 125 V.
- MPPT: 2 inputs, each with 1+1 strings, maximum operating PV current 13+13 A.
Can a hybrid inverter work without the grid, and with a generator?
Yes, the Deye SUN-6K-SG03LP1-EU works both connected to the grid and in off-grid mode, so it suits backup power. It can store energy from a diesel generator, and AC coupling lets you add it to an existing solar system.
A hybrid inverter does more than export surplus to the grid: it can keep it for yourself. ESO (Lithuanian grid operator) states:
“Part of the surplus electricity generated can be stored in an energy storage device and used in the evening.”
