However, the current firmware allows for a technical residual consumption of approx. 20 W. Users report that grid consumption of 0 W can actually be achieved via Modbus register adjustments or external energy management systems such as ioBroker. For standard applications such as full feed-in or net metering, the factory setting is usually entirely sufficient.The manufacturer should be contacted regarding configuration. It is also necessary to discuss this with the grid operator.Are the charging/discharging currents sufficient for large high-voltage batteries?Yes. According to the datasheet, the inverter allows a charging or discharging current of 50 A in each direction, which enables a power output of up to 20 kW at a battery voltage of 400 V. The official Approved Battery List lists systems such as BYD HVS/HVM, Pylontech Force H and Dyness Tower as fully compatible. This also allows large battery banks to be operated quickly and in BMS synchronisation.How many kWp can I connect without the inverter clipping?For the 15 kW model, up to 19.5 kW of PV input power is permitted. A typical 18 kWp PV system yields a good DC/AC ratio, which falls within the recommended oversizing range of 0.8. Slight clipping may occur on a few summer days, but this has little impact on the overall yield and offers valuable scope for future expansion.Can I install the inverter outdoors?Yes. The device is protected against dust and water jets to IP65, operates reliably at temperatures from –40 °C to +60 °C and tolerates 100 % humidity. For outdoor installation, the manufacturer recommends a sheltered, well-ventilated location to ensure unrestricted air cooling (≤ 55 dB(A)) and to prevent the fans from becoming blocked.Can the inverter be controlled entirely via the app or remotely?Yes. All relevant functions can be controlled remotely via the Deye Cloud or the local SUN-APP: parameter changes, firmware updates and emergency shutdowns are possible without any problems. The app guide takes you step by step through the Wi-Fi setup, including connection via the internal hotspot network. In addition, RS485, CAN, LAN and 4G sticks are available for connecting external EMS solutions.  Scope of delivery: Deye Sun 15K-SG01HP3-EU-AM2 Three-phase Hybrid Inverter 15KW 1 x Deye SUN-15K-SG01HP3-EU-AM2 inverterA three-phase high-voltage hybrid inverter with 15 kW output, integrated LCD touchscreen and two MPPT trackers.1 x Wall Mount BracketA sturdy metal mounting rail for securely fixing the unit to a load-bearing wall.1 x Wi-Fi Stick (Data Logger)A plug-in communication module for connecting to the internet for remote monitoring via the Deye Cloud or Solarman app.3 x Current Transformers (CT - Current Transformer)External clip-on current transformers for measuring energy flows at the house connection, necessary for zero export and self-consumption optimisation.1 x Set of PV Connectors (MC4-compatible)The required pairs of DC connectors (positive and negative) for connecting the PV strings to the inverter.1 x Set of Battery Connection Plugs (High Voltage)Special high-voltage connectors for the safe electrical connection of a compatible HV battery storage unit.1 x Communication Cable (BMS)A pre-assembled RJ45 data cable for connecting the inverter to the battery management system.1 x Mounting Set (Screws and Wall Plugs)A set of stainless steel screws and heavy-duty wall plugs for the proper installation of the wall mount bracket.1 x User ManualA printed manual with detailed installation instructions, circuit diagrams and safety information.

These include, among others, VDE-AR-N 4105 for Germany, EN 50549 for the EU, CEI 0-21 for Italy, G98 and G99 for Great Britain, OVE R25 for Austria, RD 1699 or RD 14 for Spain as well as NRS 097-2-1 for South Africa. Usually, no additional NA protection is required once the appropriate country profile has been activated.Which high-voltage batteries are compatible and how do I set the BMS correctly?Released storage solutions include, among others, BYD HVS and HVM, Pylontech Force H1 and H2, Dyness Tower as well as the Deye GB-L Series. Each storage unit is associated with a specific setup number, which is selected in the "Battery → Lithium → Setup Number" menu. Alternatively, the same number can be set via the DIP switches on the battery. Other models follow the same procedure and are listed in the compatibility list. As compatibility is constantly changing, it is recommended to check with the manufacturer beforehand.How much PV power can I connect without the inverter clipping?According to the data sheet, up to 26 kW DC input power is allowed, while the AC output power is 20 kW. This results in a good DC/AC ratio. In practice, around 22 to 24 kWp is recommended.How loud is the inverter in operation?In standby mode, the inverter remains almost silent, as the fans only start running at temperatures above 50 degrees Celsius or under sustained load. In normal operation, the noise level is below 45 decibels. At full load, a distinct airflow noise can be heard, but it remains below the maximum sound pressure of 55 decibels, as specified by the manufacturer. The unit is therefore well suited for basements and technical rooms.Can settings and firmware updates be carried out via the app?Via Deye Cloud or SUN-APP, all settings can be operated remotely. This includes changes to charging and export parameters, firmware updates for inverter, BMS and HMI as well as a possible emergency shutdown of the unit. The connection is made via WLAN, LAN or via the factory hotspot network. Additionally, RS485, CAN and 4G sticks are available for integrating external systems. Scope of delivery: Deye SUN-20K-SG01HP3-EU-AM2 (20 kW HV Hybrid Inverter) 1 x Deye SUN-20K-SG01HP3-EU-AM2 inverterA powerful three-phase high-voltage hybrid inverter with 20 kW power, integrated LCD touchscreen and two MPPT trackers.1 x wall mount bracketA robust metal mounting rail for secure attachment of the heavy device to a load-bearing wall.1 x Wi-Fi stick (data logger)A plug-in communications module for connection to the Internet for remote monitoring via Deye Cloud or Solarman App.3 x current transformers (CT - Current Transformer)External folding current transformers for measuring energy flows at the house connection, necessary for zero feed-in and self-consumption optimisation.1 x set of PV connectors (MC4-compatible)The necessary sets of DC plug connectors (plus and minus) for connecting the PV strings to the inverter.1 x set of battery connection plugs (high voltage)Special high-voltage plug connectors for the safe electrical connection of a compatible HV battery storage unit.1 x communication cable (BMS)A pre-assembled RJ45 data cable for connecting the inverter and battery management system.1 x mounting kit (screws and dowels)A set of stainless steel screws and heavy-duty dowels for the proper installation of the wall bracket.1 x User ManualA printed manual with detailed installation instructions, circuit diagrams and safety information.
