Deye 50 kW Hybrid Three-Phase Inverter (HV) SUN-50K-SG01HP3-EU

The Deye SUN-50K-SG01HP3-EU is a 50 kW three-phase hybrid inverter that runs on a high-voltage (HV) battery. With a 160-800 V battery range, two battery inputs, 4 MPPTs and 97.6% maximum efficiency, it is built for large-scale energy storage in factories, hotels, cold stores and agricultural sites.

Key features

• 50 kW rated output, three-phase grid connection.
• 160-800 V high-voltage (HV) lithium battery support: lower current, less heat loss and higher system efficiency.
• Two independent battery inputs, each rated for 50 A charge/discharge current.
• 4 MPPT inputs with a 150-850 V MPPT range: strings on different orientations and tilts are optimised separately.
• 97.6% maximum conversion efficiency.
• Up to 10 units in parallel, on-grid and off-grid, so the system can grow with demand.
• 100% unbalanced output on each phase: every phase can be loaded independently, even with uneven loads.
• Diesel generator input: the generator takes over when the grid is down and can also charge the battery.
• IP65 protection: dust- and water-protected wall-mounted enclosure suitable for outdoor use.

Where it is used

• Factory and workshop rooftop plants
• Cold storage facilities and hotels
• Agricultural irrigation and greenhouses
• Commercial buildings that need uninterrupted power

Installation with Aden Solar

Frequently asked questions

What is a hybrid inverter?

A hybrid inverter manages energy flow between solar panels, the grid and a battery in one device. Generation feeds the loads first, the surplus charges the battery, and critical loads keep running from the battery during an outage.

What is the difference between HV and LV batteries?

HV (high-voltage) batteries run at hundreds of volts, so the same power needs less current, thinner cables and loses less heat, which suits larger systems. LV (48 V) systems are common at household scale, easy to expand and cost-effective.

Can several inverters run in parallel?

Yes. Up to 10 inverters of the same model can run in parallel in on-grid and off-grid mode, so power can be added later without replacing the existing system.

How much battery does a 50 kW inverter need?

It depends on how many hours and which loads you want covered during an outage. Aden Solar lists the critical loads during the site survey, reviews your daily consumption and calculates the required kWh in writing.
