Three-phase hybrid inverter Deye SUN-80K-SG02HP3-EU, 80kW

This is an industrial-class hybrid inverter: it links together a large field of panels, a battery bank and the electrical installation of a hall or a company. Its role is to convert the current from the panels into the current used by the machines and, in addition, to decide when the battery is charged and when it is discharged, in order to avoid expensive hours and to keep the supply going when the grid has problems. The batteries it works with are high-voltage ones, that is many modules connected in a chain, a solution that keeps the current through the cables at reasonable values even at high power.

The 80 kW of continuous power correspond to the consumption of a production hall or of a medium-sized warehouse, and for 10 seconds the device can deliver 1.5 times this power, the margin needed when starting machines while working without the grid. Up to 128 kW of panels can be mounted on the roof, split over six independent inputs, so a roof with several slopes, different orientations or partly shaded areas can be covered without a weak zone dragging down the rest of the installation. The battery has two separate ports, each with 80 A on charge and 80 A on discharge, which allows large banks and a better distribution of the current. The IP65 enclosure resists dust and water and can be mounted outdoors, but at 606 x 927 x 314 mm and 105 kg it requires a load-bearing wall and lifting equipment. If there is a diesel generator on site, its energy can be used to charge the battery.

Rated active power 80000 W, maximum apparent power 88000 VA, output 220/380 V or 230/400 V, 50 Hz (45-55) or 60 Hz (55-65), maximum AC current 133.4 A / 127.6 A, off-grid peak 1.5 x Pn for 10 s. PV input: access power up to 160 kW, maximum PV power 128 kW, maximum DC voltage 1000 V, 6 MPPT trackers with a 150-850 V range and 2 strings per MPPT. High-voltage lithium-ion battery 160-1000 V, two independent ports, 80+80 A on charge and on discharge. Maximum efficiency 98.70%, European efficiency 98.1%, IP65, 606 x 927 x 314 mm, 105.0 kg, operating temperature -40...+60 degrees C; RS485, RS232 and CAN communication, paralleling up to 10 units, storage from a diesel generator. The commercial name in the listing does not contain the version suffix (EM4/EM6); the values above correspond to the EM6 variant in the current Deye catalogue and confirming the version at ordering is recommended.

Who it suits

Suitable for a hall, a warehouse or a company with consumption of the order of tens of kW, which has a large roof, wants to reduce the billed power peaks and accepts a high-voltage battery.

Terms explained

• Peak shaving: Using the battery precisely at the moments when the company consumes the most, so as not to pay for a contracted power higher than needed.
• MPPT: The circuit that continuously searches for the operating point at which a group of panels produces the most; six such circuits mean six roof zones working independently of one another.
• High-voltage battery: A bank of accumulators connected in a chain up to a high voltage, so that the same power passes through a lower current and through thinner cables.

Technical specifications

Recommended applications

• Production halls and warehouses with storage for peak power reduction
• Commercial photovoltaic parks with self-consumption and backup
• Hybrid systems with a diesel generator in areas with a weak grid
• Installations scalable by paralleling up to 800 kW

Warranty

5 years standard, 10 years depending on the market

Technical details

Series-level specifications — valid for the product family

Deye SUN-80K-SG02HP3-EU is part of the commercial and industrial SG02HP3-EU-EM6 series (60-80 kW), intended for high-power photovoltaic systems with storage. The inverter works with high-voltage lithium-ion batteries in the 160-1000 V range, through two independent battery ports, each with 80 A on charge and 80 A on discharge (80+80 A).

On the photovoltaic side it accepts a PV access power of up to 160 kW and a maximum PV power of 128 kW, at a maximum DC voltage of 1000 V. There are 6 MPPT trackers with a 150-850 V range and 2 strings on each MPPT, a configuration that allows industrial roofs with several orientations or partial shading.

The AC output is 80000 W of rated active power and 88000 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 133.4 A / 127.6 A. In off-grid operation it withstands 1.5 x the rated power for 10 seconds. The maximum efficiency is 98.70%, and the European efficiency 98.1%.

The enclosure has IP65 protection, dimensions of 606 x 927 x 314 mm and a mass of 105.0 kg, with a thermal range of -40...+60 degrees C. Communication is via RS485, RS232 and CAN; a maximum of 10 units can be paralleled and energy can be stored from a diesel generator. The name in the listing does not contain the version suffix (EM4/EM6), the data above correspond to the EM6 variant in the current Deye catalogue.
