Deye Sun 15K-SG01HP3-EU-AM2 Three-phase hybrid inverter 15KW

Efficient energy conversion using high-voltage technology

The SUN-15K-SG01HP3-EU-AM2 utilises a high-voltage battery voltage of up to 700 V, ensuring that charging and discharging processes are particularly efficient. With a maximum efficiency of 97,6 % and an impressive MPPT efficiency of 99,9 %, it ranks among the most efficient units in its class. Two MPP trackers ensure optimum energy yield even with complex module layouts.

Flexibility and scalability

Whether as part of a new energy system or for retrofitting existing PV installations: the inverter can be used flexibly. Thanks to the ability to connect up to 10 units in parallel and support for AC pairs, the system is suitable for a wide variety of installation configurations. The intelligent charging schedule allows for six individually definable time slots for battery use.

Reliability and protection

With IP65 protection rating, comprehensive safety features such as anti-islanding protection, short-circuit and overvoltage protection, as well as residual current monitoring, the SUN-15K-SG01HP3-EU-AM2 is ideally equipped for safe operation – even at extreme temperatures between -45 °C and +60 °C. The intelligent cooling system ensures quiet, stable operation.

Who is the Deye SUN-15K-SG01HP3-EU-AM2 suitable for?

This inverter is ideal for:

• Private households and businesses that rely on high-voltage energy storage systems
   
• Installers looking for flexible retrofit solutions that take up little space
   
• Off-grid applications requiring diesel generator backup
   
• Users with a complex load profile who require efficient charging/discharging management
   
• Systems offering high efficiency whilst maintaining a compact design

Can I really limit the grid draw to 0 W?

In ‘Zero-Export-to-CT’ operating mode, the inverter reduces the feed-in to almost zero. However, the current firmware allows for a technical residual draw of approx. 20 W. Users report that it is actually possible to achieve 0 W grid consumption 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 generally entirely sufficient.
The manufacturer should be contacted regarding configuration. It is also necessary to discuss this with the network operator.

Are the charging/discharging currents sufficient for large high-voltage batteries?

Yes. According to the data sheet, 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 means that even large battery banks can be operated quickly and in synchronisation with the BMS.

How many kWp can I connect without the inverter clipping?

For the 15-kW model, up to19,5 kW 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, in return, offers valuable scope for future expansion.

Can I install the inverter outdoors?

Yes. The unit is protected against dust and water jets to IP65, operates reliably at temperatures ranging 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 can be carried out 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.
