All four models share 2 MPPT inputs (one string each), 13 + 13 A max. DC input current, 1000 V max. DC voltage, IP65 and 98.3 % max. efficiency. Housing depth and weight differ as well: the 4, 6 and 8 kW models are 330 × 457 × 185 mm and 10 kg, the 10 kW model is 330 × 457 × 205 mm and 11 kg.
Choose the 6 kW model if you plan up to 7.8 kW of panels. If less is enough, look at the Deye SUN-4K-G05 (4 kW) (up to 5.2 kW DC); for more panels, the Deye SUN-8K-G05 (8 kW) (up to 10.4 kW) or the Deye SUN-10K-G05 (10 kW) (up to 13 kW). We help to choose the right power according to your roof and consumption; the consultation before purchase is free.
Who is the 6 kW SUN-6K-G05 solar inverter for?
The Deye SUN-6K-G05 is a 6 kW three-phase grid-tied inverter for sites that use electricity in the daytime: a workshop, an office, a shop, a farm with refrigeration or pumps. There solar generation and consumption coincide, so storage is not always needed. Up to 7.8 kW of solar panels can be connected to this model (max. DC input power). If most of your electricity is used in the evening, it is worth comparing with a hybrid inverter. We offer those too and will gladly work out which option suits your site better.
Can a battery be connected to the SUN-6K-G05 grid-tied inverter?
No, a battery cannot be connected to the SUN-6K-G05 grid-tied inverter. Energy storage needs a hybrid inverter or a separate storage inverter. Without storage, electricity is bought from the grid again in the evening when the sun is gone. ESO (Lithuanian grid operator) describes the benefit of storage like this:
“Part of the surplus electricity generated can be stored in an energy storage device and used in the evening.”
How to connect solar panels to the SUN-6K-G05
The SUN-6K-G05 has 2 MPPT inputs with one panel string each. Each input takes up to 13 A and the maximum DC voltage is 1000 V. The inverter starts at 140 V and the MPPT operating range is 120–850 V.
- Max. DC input power: 7.8 kW.
- Max. short-circuit current: 19.5 + 19.5 A.
- String voltage must fit within the 120–850 V range and not exceed 1000 V.
- DC connectors: MC-4 compatible, with an integrated DC switch.
The manufacturer does not name specific compatible panels, so we choose the number of panels and the wiring layout to suit your roof and the panels you select.
Grid connection, monitoring and protections
The Deye SUN-6K-G05 connects to a three-phase grid: rated output voltage 3L/N/PE 380 V (323–418 V) or 400 V (340–440 V), rated AC current 8.7 A, maximum 9.6 A. Frequency is 50 Hz, optionally 60 Hz.
