Deye SUN-125K-SG02HP3-EU-GM10 Three-Phase Hybrid Inverter, 125kW

This is the most powerful version of its family and addresses industrial projects: it gathers the energy of a large panel field, converts it into the current used by the factory installation and can keep it in a battery bank for later. In practice, it allows a company to consume during the day what it produces itself and to use in the evening or at the tariff peak the stored energy, and in case of an outage to keep supplied the processes that cannot tolerate interruption. The batteries are of the high voltage type, that is modules chained up to a high voltage, which keeps the current through the cables at manageable values even at this power.

The 125 kW of continuous power cover the consumption of a production unit, and for 10 seconds the device can deliver 1,5 times this value, the margin needed when starting machinery in off-grid mode. On the panel side up to 200 kW can be connected, split over ten independent inputs, which means that a complicated roof, with different pitches and orientations, can be covered zone by zone, each group working at its own maximum. The battery is charged and discharged over two paths, with 100+100 A. It is a piece of industrial installation equipment, not a house wall unit: 734 x 1091 x 344 mm and 161,7 kg require a supporting structure and lifting means, and the IP65 enclosure allows outdoor installation. Several units can be connected together, up to 1,25 MW, and the battery can also be charged from a diesel generator.

Nominal active power 125000 W, maximum apparent power 135000 VA, output 220/380 V or 230/400 V, 50 Hz (45-55) or 60 Hz (55-65), maximum AC current 204,6 A / 195,7 A, off-grid peak 1,5 x Pn for 10 s. PV input: maximum power 200000 W, maximum DC voltage 1000 V, 10 MPPT trackers with a 150-850 V range and 2 strings each (2+2+2+2+2+2+2+2+2+2). High voltage lithium-ion battery 160-1000 V, 100+100 A on charge and discharge. Maximum efficiency 98,70%, European efficiency 98,10%, IP65, 734 x 1091 x 344 mm, 161,7 kg, working temperature -40...+60 degrees C. Basic communication RS485/RS232/CAN, with optional GPRS, WiFi, Bluetooth, 4G or LAN modules; paralleling up to 10 units, respectively 1,25 MW, and storage from a diesel generator.

Who it suits

Suitable for large industrial and commercial projects, with hundreds of kW installed and continuous consumption, where the battery is used for reducing power peaks and for the continuity of critical processes.

Terms explained

• Microgrid: An electrical installation that can also work separately from the public grid, supplied from panels, battery and possibly a generator, when the external supply is missing.
• Paralleling: Connecting several identical inverters so that they work as a single larger system, useful when the project grows in stages.
• Apparent power (VA): The total power the device can put on the cables, including the part that does not turn into useful work; it matters when sizing the fuses and the cables.

Technical specifications

Recommended applications

• Industrial projects with high capacity storage (peak shaving)
• C&I photovoltaic plants with self-consumption and controlled export
• Hybrid plants PV + batteries + diesel generator
• Microgrids and backup systems for critical processes

Warranty

5 years standard, 10 years depending on the market

Technical details

Specifications confirmed from the manufacturer's datasheet

Deye SUN-125K-SG02HP3-EU-GM10 is the top version of the SG02HP3-EU-GM10 series (100-125 kW), a three-phase hybrid inverter for commercial and industrial projects with storage. It works with high voltage lithium-ion batteries in the 160-1000 V range, over two power paths, with 100+100 A maximum charge and discharge current.

The photovoltaic side accepts up to 200 kW of maximum PV power, at a DC voltage of maximum 1000 V. The 10 MPPT trackers, with a 150-850 V range and 2 strings each (2+2+2+2+2+2+2+2+2+2), allow the connection of complex photovoltaic generators, with different orientations and tilts, without tracking losses.

The AC output is 125000 W of nominal active power and 135000 VA of maximum apparent power, at 220/380 V or 230/400 V, 50 Hz (45-55) or 60 Hz (55-65), with a maximum current of 204,6 A / 195,7 A. In off-grid mode it delivers 1,5 x the nominal power for 10 seconds. The maximum efficiency is 98,70%, and the European one 98,10%.

The enclosure has IP65 protection, dimensions of 734 x 1091 x 344 mm and a mass of 161,7 kg; the thermal range is -40...+60 degrees C. Basic communication is RS485/RS232/CAN, with optional GPRS, WiFi, Bluetooth, 4G or LAN modules. A maximum of 10 units can be connected in parallel (up to 1,25 MW) and energy storage from a diesel generator is accepted.
