Efficient energy conversion using high-voltage technology
With a maximum DC input power of 32,500 W and an MPPT efficiency of 99.9%, the SUN-25K delivers outstanding performance. The intelligent MPPT control ensures high yields even in the event of shading or unevenly oriented module arrays. The inverter is optimised for high-voltage lithium-ion batteries (160–700 V), enabling particularly high charging and discharging efficiency.
Flexibility and scalability
Whether grid-connected, hybrid or off-grid: the inverter offers flexible application options. The AC and DC connections enable existing solar systems to be easily retrofitted. The ability to connect up to 10 units in parallel, along with two separate battery inputs, provides scalable solutions for growing energy requirements. With six freely definable time slots for charging and discharging the battery, energy can be used or stored as required.
Reliability and protection
Thanks to protection class IP65 and intelligent cooling, operation is guaranteed even under demanding conditions. Safety features such as reverse polarity, overvoltage, short-circuit and residual current protection ensure maximum operational safety. Certifications in accordance with VDE-AR-N 4105, EN 50549 and other international standards confirm the high quality of the unit.

FAQs for the Deye SUN-25K-SG01HP3-EU-AM2
Which grid codes are stored in the inverter?
The inverter includes all standard grid codes, which can be switched directly in the ‘Setting → Grid’ menu. These include, amongst others, VDE-AR-N 4105 for Germany, EN 50549 for the EU and CEI 0-21 for Italy. As a rule, no additional NA protection is required once the appropriate country profile has been activated.
Which high-voltage batteries are compatible, and how do I configure the BMS correctly?
Approved storage solutions include, amongst others, BYD HVS and HVM, Pylontech Force H1 and H2, Dyness Tower, and the Deye GB-L Series. Each storage unit is assigned a specific setup number, which is selected in the ‘Battery → Lithium → Setup Number’ menu. Alternatively, the same number can be set using the DIP switches on the battery. As manufacturers may make changes at any time, it is recommended that you check against a current compatibility list beforehand.
How much PV power can I connect without the inverter clipping?
According to the data sheet, a DC input power of up to 32,500 W is permitted, whilst 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, which corresponds to approximately 27.5 to 30 kWp.
How loud is the inverter when in operation?
In standby mode, the inverter remains virtually silent, as the fans only start up when required. In normal operation, the noise level is below 55 decibels, as specified by the manufacturer. The unit is therefore well suited for basements and plant rooms.
Can settings and firmware updates be carried out via the app?
Yes, all settings can be controlled remotely via the Deye Cloud or the SUN-APP. This includes changes to charging and export parameters, firmware updates for the inverter, BMS and HMI, as well as the option to perform an emergency shutdown of the device. The connection is established via Wi-Fi, LAN or the factory hotspot network.
