However, the current firmware allows a technical residual consumption of approx. 20 W. Users report that adjustments to Modbus registers or external energy management systems such as ioBroker can indeed achieve 0 W grid consumption. For standard applications such as full feed-in or net metering, the factory setting is usually entirely sufficient.Are the charge/discharge currents sufficient for large high-voltage batteries?Yes. According to the data sheet, the inverter allows 50 A charging or discharging current in each direction, which enables up to 20 kW output at a battery voltage of 400 V. Systems such as BYD HVS/HVM, Pylontech Force H and Dyness Tower are listed as fully compatible in the official Approved Battery List. This allows even large storage blocks to be operated quickly and in sync with the BMS.How much kWp can I connect, without the inverter clipping?On the 15 kW model, up to 30 kW PV access power and 24 kW PV input power are permitted. A typical 18 kWp PV installation results in a DC/AC ratio of 1.2, which is within the recommended oversizing range of 0.8 to 1.3. Slight clipping may occur on a few summer days but has little effect on total yield and offers valuable expansion reserves.Can I install the inverter outdoors?Yes. The device is protected against dust and water jets according to IP65, operates reliably at temperatures from –40 °C to +60 °C and tolerates 100 % humidity. For outdoor installation, the manufacturer recommends a protected, well-ventilated location to ensure unrestricted air cooling (≤ 55 dB(A)) and prevent fan blockage.Can the inverter be fully controlled via app or remote access?Yes. All relevant functions can be remotely controlled via Deye Cloud or the local SUN APP: parameter changes, firmware updates and emergency shutdowns are no problem. The app manual guides you step by step through the Wi-Fi setup including connection using the internal hotspot network. RS485, CAN, LAN and 4G sticks are also 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 robust metal mounting rail for securely fastening the device 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 Deye Cloud or Solarman App.3 x Current Transformer (CT)External clamp current transformers for measuring energy flows at the house connection, required for zero feed-in and optimising self-consumption.1 x set of PV connectors (MC4 compatible)The required pairs of DC connectors (plus and minus) 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.1 x communication cable (BMS)A prefabricated RJ45 data cable for connecting the inverter and the battery management system.1 x mounting kit (screws and plugs)A set of stainless steel screws and heavy-duty plugs for professional installation of the wall bracket.1 x User ManualA printed manual with detailed installation instructions, circuit diagrams and safety notes.

These include 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 and RD 14 for Spain, as well as NRS 097-2-1 for South Africa. As a rule, no additional NA protection is required as soon as the appropriate country profile has been activated.Which high-voltage batteries 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, as well as the Deye GB-L Series. Each storage is assigned a specific setup number, which is selected in the menu “Battery → Lithium → Setup Number”. Alternatively, the same number can be set using the DIP switches on the battery. Other models follow the same procedure and are listed in the compatibility list.How much PV output can be connected without inverter clipping?According to the data sheet, up to 30 kW DC input is permitted, while the AC output is 20 kW. This gives a DC/AC ratio of 1.5. In practice, a ratio of 1.1 to 1.2 is recommended, which equates to around 22 to 24 kWp. Even with 26 to 28 kWp, only minor losses due to clipping occur on a few days according to experience.How loud is the inverter during operation?In standby operation, the inverter remains almost silent as the fans only start at temperatures above 50°C or under sustained load. In normal operation, the noise level is below 45 decibels. Under full load, a clear airflow noise can be heard, but it stays below the maximum sound pressure of 55 decibels, as specified by the manufacturer. The device is therefore well suited for basements and technical rooms.Can settings and firmware updates be carried out via app?Via the Deye Cloud or the SUN-APP, all settings can be managed remotely. This includes changes to charging and export parameters, firmware updates for inverter, BMS, and HMI as well as an emergency shutdown. Connection is established via WiFi, LAN, or the factory hotspot network. RS485, CAN, and 4G sticks are also 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 output, integrated LCD touchscreen, and two MPPT trackers.1 x Wall Mount BracketA solid metal mounting rail for safe installation of the heavy device on a load-bearing wall.1 x Wi-Fi stick (data logger)A plug-in communication module for Internet connection for remote monitoring via Deye Cloud or Solarman App.3 x current transformer (CT - Current Transformer)External clamp current transformers to measure the power 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 plugs (plus and minus) to connect the PV strings to the inverter.1 x set of battery connection plugs (high-voltage)Special high-voltage connectors for safe electrical connection of a compatible HV battery storage system.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 plugs)A set of stainless steel screws and heavy-duty wall plugs for correct installation of the wall mount.1 x user manualA printed manual containing detailed installation instructions, diagrams and safety notes.
