Deye Sun 20K-SG01HP3-EU-AM2 Three Phase Hybrid Inverter 20KW

Which grid codes are stored in the inverter?

The inverter supports all standard grid codes, which can be selected directly in the ‘Setting → Grid’ menu. These include, amongst others, VDE-AR-N 4105 for Germany, EN 50549 for the EU, CEI 0-21 for Italy, G98 and G99 for the UK, OVE R25 for Austria, RD 1699 and RD 14 for Spain, and NRS 097-2-1 for South Africa. 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. Other models follow the same procedure and are listed in the compatibility list. As compatibility is constantly changing, it is recommended that you check with the manufacturer beforehand.

How much PV power can I connect without the inverter clipping?

According to the data sheet, DC input power of up to 26 kW is permitted, whilst 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 when in operation?

In standby mode, the inverter remains virtually silent, as the fans only start up at temperatures above 50 degrees Celsius or under prolonged load. In normal operation, the noise level is below 45 decibels. Under full load, a distinct air noise is audible, but it remains below the maximum sound pressure level of 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?

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-set hotspot network. RS485, CAN and 4G dongles are also available for integrating external systems.
