Deye 25 kW Hybrid Three-Phase Inverter (HV) SUN-25K-SG02HP3-EU

The Deye SUN-25K-SG02HP3-EU is a 25 kW three-phase hybrid inverter that runs on a high-voltage (HV) battery. With a 160-700 V battery range and a wide 150-850 V MPPT range, it is a storage-ready solar solution for large villas on a three-phase supply, offices and small to medium businesses.

Key features

• 25 kW rated output, three-phase grid connection.
• 160-700 V high-voltage (HV) lithium battery support: lower current, less heat loss and higher system efficiency.
• Wide 150-850 V MPPT range for flexible designs with long panel strings.
• 100% unbalanced output on each phase: every phase can be loaded independently, even with uneven loads.
• IP65 protection: dust- and water-protected wall-mounted enclosure suitable for outdoor use.
• Hybrid operation: runs with the grid when present and from the battery during an outage; surplus generation is stored.

Where it is used

• Large villas on a three-phase supply
• Offices, shops and small businesses
• Farms, barns and agricultural buildings
• Rooftop solar plants with storage

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.

Should I choose a single-phase or three-phase inverter?

It depends on your grid connection and loads. Single-phase supplies use a single-phase inverter; three-phase supplies and three-phase motors, pumps or compressors need a three-phase inverter. Aden Solar checks your connection during the survey.

How much battery does a 25 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.
