Choose the SUN-5K-SG04LP3-EU when the site is three-phase and 5 kW is enough. If the system is single-phase, the SUN-5K-SG03LP1-EU has the same 5 kW rating, but is lighter (25 kg) and quieter (below 30 dB); the SUN-6K-SG03LP1-EU is the single-phase 6 kW option. If a three-phase site needs more power, look at the SUN-8K-SG04LP3-EU (8 kW, 190 A battery current).
What is a 3 phase hybrid inverter used for?
The Deye SUN-5K-SG04LP3-EU is a three-phase (3L+N+PE) inverter for residential and commercial PV systems, backup power, off-grid (island) systems and adding storage to an existing solar system through AC coupling. An unbalanced load is allowed: up to 50 % of rated power on a single phase.
Hybrid inverter with battery: which batteries fit?
The Deye SUN-5K-SG04LP3-EU connects to 40-60 V (48 V low-voltage) 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 10 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-SG04LP3-EU accepts a maximum PV access power of 10,000 W and a maximum PV input power of 7500 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 200-650 V, maximum PV input voltage is 800 V and start-up voltage is 160 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-SG04LP3-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.”
