Deye SUN-10K-G05 10 kW three-phase string inverter

Deye SUN-10K-G05 is a three-phase transformerless string grid-tie inverter, the highest-rated of the four G05 models compared here (4, 6, 8 and 10 kW): rated output 10 kW (max. active power 11 kW), up to 13 kW of DC input, two MPPT inputs and a maximum efficiency of 98.3 %. It is meant for a solar PV system without a battery, where most of the electricity is used during the day.

Technical specifications

How the Deye SUN-10K-G05 differs from the 4, 6 and 8 kW models

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 10 kW model if you plan up to 13 kW of panels. If less is enough, look at the Deye SUN-4K-G05 (4 kW) (up to 5.2 kW DC), the Deye SUN-6K-G05 (6 kW) (up to 7.8 kW) or the Deye SUN-8K-G05 (8 kW) (up to 10.4 kW). Note that this model starts at 250 V and its MPPT range is 200–850 V, while the 4, 6 and 8 kW models start at 140 V with a 120–850 V range. We help to choose the right power according to your roof and consumption; the consultation before purchase is free.

What is a 10 kW three-phase grid-tie solar inverter used for?

The Deye SUN-10K-G05 is a 10 kW three-phase grid-tie inverter for sites that use electricity during the day: production, an office, a shop, or a farm with refrigeration or pumps. In such places solar generation and consumption coincide in time, so a battery is not always needed. Up to 13 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 supply those too and will gladly work out which option suits your site better.

Can a battery be connected to the SUN-10K-G05 grid-tie inverter?

No, a battery cannot be connected to the SUN-10K-G05 grid-tie inverter. An energy storage system 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) states:

“Part of the surplus electricity generated can be stored in an energy storage device and used in the evening.”

How do you connect solar panels to the SUN-10K-G05 inverter?

The SUN-10K-G05 has 2 MPPT inputs, one panel string per input. Each input accepts up to 13 A and the maximum DC voltage is 1000 V. The inverter starts at 250 V and the MPPT operating range is 200–850 V.

• Maximum DC input power: 13 kW.
• Maximum short-circuit current: 19.5 + 19.5 A.
• The string voltage must fit within 200–850 V and not exceed 1000 V.
• DC connectors: MC-4 compatible, with an integrated DC switch.

The manufacturer does not name compatible panel models, so we choose the number of panels and the wiring scheme to suit your roof and the panels you pick.

Grid connection, monitoring and protections

The Deye SUN-10K-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 14.5 A and maximum 15.9 A. Frequency is 50 Hz, 60 Hz optional.
