Deye SUN-50K-SG01HP3-EU-BM4

This device is the brain of a solar system with storage of industrial size: it takes the current from hundreds of panels, converts it into the current used by machinery and automatically splits it between the loads, the battery bank and the grid. It has four independent trackers, that is it can separately manage four roof or ground zones, each with its own orientation. The battery is connected on two separate inputs, which allows a large energy store to be built, split into two branches.

The 50,000 W support in parallel the equipment of an industrial hall or of a logistics centre, with up to 83.4 A on each phase. Up to 100 kWp of panels can be connected, of which the device processes at most 80 kW, so the system gives useful power in the morning, in the evening or in overcast weather as well. The two battery inputs each accept 50 A on charge and 50 A on discharge, that is 100 A in total, suitable for large banks of lithium-ion accumulators. The device weighs 80 kg and has an IP65 enclosure with fans, so it can also be mounted outdoors, but mounting requires two people and a solid support. For even larger installations, up to 10 inverters can be connected in parallel, with the possibility of charging from a generator.

Active power 50,000 W, maximum apparent 55,000 VA, three-phase output 220/380 V or 230/400 V, 50/60 Hz, 83.4/79.8 A maximum current per phase. DC side: 4 MPPTs with 2 strings each, maximum voltage 1000 V, MPPT range 150-850 V, 36 A maximum operating current per tracker, 55 A permissible short-circuit current, 100 kWp of connectable modules and 80 kW of processed DC power; maximum efficiency 97.6%, European 97.0%, MPPT above 99%. Storage on two independent battery inputs 160-800 V, 50+50 A on charge and 50+50 A on discharge. Footprint 527 x 894 x 294 mm, 80 kg, IP65 with intelligent fan cooling, -40...+60 degrees C, RS485/RS232/CAN communication and optional WiFi, LAN, 4G or GPRS monitoring, paralleling of up to 10 inverters and charging from a generator; compliance with IEC 61727, IEC 62116, EN 50549.

Who it suits

Suited to industrial halls, logistics parks and high-capacity commercial storage systems, with photovoltaic arrays of tens of kWp and large battery banks.

Terms explained

• Two battery inputs: The accumulator bank can be split into two separate branches, which makes expansion and current distribution easier.
• Tracker: Here it means the electronic input that seeks the optimum operating point of the panels, not a mechanical system that turns the panels after the sun.
• Parallel installations: Several identical inverters working in sync as a single system, for powers of the order of hundreds of kW.

Technical specifications

Recommended applications

• Industrial halls and logistics parks
• High-capacity commercial storage systems
• Parallel installations up to 500 kW
• Microgrids with generator and back-up

Technical details

Specifications confirmed from the manufacturer's datasheet

SUN-50K-SG01HP3-EU-BM4 is the top of the Deye three-phase hybrid range with high-voltage battery, dedicated to commercial and industrial applications. It has 4 MPPT trackers, each with 2 strings, maximum DC voltage 1000 V and MPPT range 150-850 V; the maximum operating current is 36 A per tracker, and the permissible short-circuit current 55 A. Up to 100 kWp of modules can be connected, with a maximum of 80 kW of processed DC power, so a significant oversizing of the photovoltaic array.

Storage uses two independent battery inputs in the 160-800 V range, each with 50 A on charge and 50 A on discharge (100 A in total), suitable for large banks of lithium-ion accumulators. The three-phase AC output 220/380 V or 230/400 V delivers 50,000 W of rated active power and 55,000 VA of apparent power, with 83.4 A maximum current per phase. The maximum efficiency is 97.6%, the European efficiency 97.0%, and the MPPT efficiency exceeds 99%.

The enclosure of 527 x 894 x 294 mm and 80 kg has IP65 protection rating and intelligent fan cooling, operating between -40 and +60 °C. Communication is via RS485/RS232/CAN, with optional WiFi, LAN, 4G or GPRS monitoring. Paralleling of up to 10 inverters and charging from a generator are supported; compliance with IEC 61727, IEC 62116, EN 50549.
