The Deye SUN-5K-SG03LP1-EU is a single-phase 5 kW hybrid inverter with 2 MPPTs: maximum PV input power 6500 W and a battery charge / discharge current of up to 120 A. It differs from the three-phase SUN-5K-SG04LP3-EU by its single-phase connection (L+N+PE), 25 kg weight, noise below 30 dB and parallel operation of up to 16 units; it differs from the SUN-6K-SG03LP1-EU by 1 kW lower rated power and a 120 A (not 135 A) battery current. It suits a single-phase site where 5 kW of rated AC power with a 40-60 V battery is enough.

Choose the SUN-5K-SG03LP1-EU when the site is single-phase, 5 kW is enough and low weight and noise matter (25 kg, below 30 dB). If you connect to three phases (3L+N+PE) or need to power an unbalanced load, look at the SUN-5K-SG04LP3-EU, which has the same 5 kW rating. If a single-phase site needs more power, the SUN-6K-SG03LP1-EU (6 kW, 135 A battery current) fits, and the three-phase 8 kW option is the SUN-8K-SG04LP3-EU.
What is a 5 kW hybrid inverter with battery used for?
The Deye SUN-5K-SG03LP1-EU is built for single-phase systems (L+N+PE): home solar systems with batteries, backup power, off-grid (island) systems and adding storage to an existing solar system through AC coupling. Of the four models compared here it is one of two 5 kW inverters, and the quieter of the two: below 30 dB with natural cooling.
Hybrid inverter with battery: which batteries fit?
The Deye SUN-5K-SG03LP1-EU connects to 40-60 V batteries, either lead-acid or lithium-ion; for Li-ion batteries the charging strategy adapts to the BMS. It has one battery input and a maximum charge / discharge current of 120 A. Several batteries can be connected in parallel, up to 16 inverters can run in parallel in both grid-tied and off-grid modes, and 6 time periods can be programmed for when the battery charges and discharges.
How much solar can you connect to a 5 kW hybrid inverter?
The Deye SUN-5K-SG03LP1-EU accepts a maximum PV access power of 10,000 W and a maximum PV input power of 6500 W; these are two different figures. Rated AC power is 5 kW (5500 VA maximum), and in off-grid mode it can supply twice the rated power for 10 s. The MPPT range is 150-425 V, maximum PV input voltage is 500 V and start-up voltage is 125 V. There are 2 MPPT inputs with 1+1 strings and a maximum operating PV current of 13+13 A.
Can a hybrid inverter work without the grid or with a generator?
Yes, the Deye SUN-5K-SG03LP1-EU works both connected to the grid and in off-grid (island) 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. ESO (Lithuanian grid operator) states:
“Part of the surplus electricity generated can be stored in an energy storage device and used in the evening.”
