Deye Inverter SUN-25K-SG01HP3-EU-AM2 25000 W 150 V, 850 V - 230 V, 400 V

The Deye SUN-25K-SG01HP3-EU-AM2 is a powerful, three-phase hybrid inverter with high-voltage battery compatibility. It was developed especially for demanding PV-applications in living and commercial areas and impresses through its high efficiency, flexible usage possibilities and robust design.

Efficient energy conversion using high-voltage technology

With a maximum DC input power of 32,500 W and a MPPT efficiency of around 99.9% the SUN-25K achieves an excellent performance. The intelligent MPPT control ensures high yields, even in the event of shadows or module fields which are not aligned with each other. The inverter is optimized for high-voltage lithium-ion batteries (160–700 V), while WAS enables a particularly high charging and discharging efficiency.
Flexibility and scalability

Whether network-connected, hybrid or off-grid: The inverter offers flexible applications. The AC and DC coupling enables the easy retrofitting of existing solar systems. The parallel connection of up to 10 devices as well as two separate battery inputs offer scalable solutions for increasing power requirements. With six freely definable windows for charging and discharging the battery, the energy can be used or stored specifically.

Reliability and protection

Operation is ensured under demanding conditions thanks to the IP65 protection and intelligent cooling. Safety functions such as polarity reversal, overvoltage, short-circuit and fault current protection ensure maximum operational safety. The certifications according to VDE-AR-N 4105, EN 50549 and other international standards confirm the high quality of the device

Who is the Deye SUN-25K-SG01HP3-EU-AM2 for? This inverter is Ideal for:

-Businesses with Hohem energy requirements and storage requirements
-Homeowners who seek maximum autarky with high-voltage technology
-Installers planning flexible, future-proof systems
-Project developers who implement AC-coupled retrofit solutions

FAQ for Deye SUN-25K-SG01HP3-EU-AM2

Which grid codes are stored in the inverter?

The inverter contains all common grid codes that can be changed directly in the menu "Setting → Grid". These include VDE-AR-N 4105 for Germany, EN 50549 for the EU and CEI 0-21 for Italy. As a rule, this does not require additional NA protection once the appropriate country profile has been activated.
Which high-voltage memory units are compatible and how do ICH set up the BMS correctly?

Shared storage solutions include BYD HVS and HVM, Pylontech Force H1 and H2, Dyness Tower and the Deye GB-L Series. Each memory is stored with a specific setup number, which is selected in the menu "Battery → Lithium → Setup Number". Alternatively, the same number can be set via the DIP switches on the battery.
How much PV power can ICH connect without the inverter clipping?

The data sheet allows up to 32,500 W DC input power, while the AC output power is 25 kW. This results in a DC/AC ratio of 1.3. In practice, a ratio of 1.1 to 1.2 is recommended, while WAS corresponds to approximately 27.5 to 30 kWp.
How loud is the converter operating?

In standby mode the inverter remains nearly silent because the fans start up only when needed. During normal operation the noise level is less than 55 decibels, as indicated by the manufacturer. The device is thus well suited for cellars and technical rooms.

Can settings and firmware updates be performed via APP?

Yes, using the Deye Cloud or the SUN APP all settings can be controlled remotely. This includes changes to load and export parameters, firmware updates for inverters, BMS and HMI, and a possible emergency shutdown of the device. The connection is done via WLAN, LAN or via the factory-installed Hotspot-Network.
