Deye SUN-80K-G04P3-EU-AM4 80 kW Three-Phase String Inverter

The Deye SUN-80K-G04P3-EU-AM4 carries 80 kW of three-phase AC output behind four independent MPP trackers, and its datasheet allows 120 kW of modules on a 1100 V ceiling. It reaches 98.7% maximum efficiency and weighs 53.7 kg. Its natural home is a commercial or industrial rooftop where one cabinet should carry a large array split over several roof planes.

Four trackers for varied roof planes

Industrial roofs are rarely uniform: skylights, ducts and different slopes break an array into groups. Four independent trackers let each group run at its own operating point, so shade in one corner does not pull down the rest. At 80 kW the unit is a step between the 36 kW class and the 110 kW class, and the 53.7 kg enclosure can be handled by two people with the bracket already fixed.

Features Deye lists

• Four trackers, up to 98.7% efficiency.
• Export limiting and a virtual-synchronous-generator mode.
• String monitoring and PID prevention available as options.
• Surge arresters on both sides, arc-fault interrupter optional.

Technical specification

Four ratings share the datasheet: 60, 70, 75 and 80 kW.

Sizing the 80 kW unit

The 133.3 A maximum AC current per phase sets the cable and breaker for the 80K column. The DC to AC ratio of up to 1.5 allows a generous array, but check the string voltage at the lowest site temperature against the 1100 V limit. With four trackers you can combine strings of equal tilt and azimuth on each, which keeps mismatch low on a roof with several planes.

Installing it, from the user manual

According to the manual the cabinet goes on a wall or frame strong enough for its weight, stays almost upright within a small permitted tilt, and keeps the spacing drawn in the gap diagram. The start sequence is AC breaker, PV breaker and then the inverter switch. A breaker must not be shared between inverters, and a ventilated space is needed if the unit is in an airtight room. It also lists the tools, from a crimping tool and wire stripper to a hydraulic crimper, and gives AC wire sizes and torque by rating.

Factory roofs in the Gulf

Metal roofs and plant rooms in the region run hot, and the inverter derates above 45 degrees C. A shaded wall, a canopy, a clear fan path and service space in front all help the unit hold full output through summer. Check the grid code that the utility requires before commissioning.

Practical notes

A 120 kW PV input against 80 kW of AC gives a ratio of 1.5. Four trackers at 40 A each carry up to sixteen strings, which suits roofs with several planes. The cabinet is 698 mm wide and 613 mm high and weighs 53.7 kg, so plan a bracket and a lifting aid. The datasheet gives noise up to 55 dB(A), so keep the fan side away from occupied areas. Label every string at installation to simplify later fault finding.

Selection and installation notes

A grid-tied string inverter is selected from the array size, the string voltage window and the grid connection. Check the string open-circuit voltage at the lowest site temperature against the input limit and the operating voltage at high temperature against the MPPT window, balance the strings on each tracker, fit DC isolators and surge protection and keep the clearances on the data sheet. In hot sites allow for output derating, shade the unit and have the grid settings approved by the utility before connection.
