FAQs about the Deye SUN-25K-SG01HP3-EU-AM2
Which grid codes are stored in the inverter?
The inverter contains all common grid codes, which can be changed directly in the "Setting → Grid" menu. These include 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 as soon as the appropriate country profile has been activated.
Which high-voltage storage systems are compatible and how do I set up the BMS correctly?
The approved storage solutions include BYD HVS and HVM, Pylontech Force H1 and H2, Dyness Tower and the Deye GB-L Series. Each storage system 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.
How much PV power can I connect without the inverter clipping?
According to the data sheet, up to 32,500 W DC input power is permitted, 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, which corresponds to around 27.5 to 30 kWp.
How loud is the inverter 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 device is therefore well suited for basements and utility rooms.
Can settings and firmware updates be carried out via 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 inverters, BMS and HMI as well as a possible emergency shutdown of the device. The connection is made via WLAN, LAN or the factory hotspot network.
