Deye Inverter SUN-20K-SG01HP3-EU-AM2 20000 W - 230 V, 400 V

The Deye SUN-20K-SG01HP3-EU-AM2 is a powerful three-phase hybrid inverter with high-voltage battery compatibility. It impresses with its high efficiency, flexible usage possibilities and maximum scalability – Ideal for demanding solar systems in residential and commercial projects.

Efficient energy conversion using high-voltage technology

The SUN-20K-SG01HP3-EU-AM2 uses high-voltage lithium-ion batteries (160–700 V), which enable a particularly high charging and discharging efficiency. With an MPPT efficiency of 99.9% and a maximum efficiency of 97.6% it ensures an optimum use of the available solar energy even in variable weather conditions.
Flexibility and scalability

Thanks to the possibility of parallel connection of up to 10 devices, the inverter is suitable for complex new buildings as well as for retrofitting larger systems. Two independent MPP trackers each with two inputs optimize the energy yield across multiple module fields. Six freely definable time windows for charging and discharging the battery provide maximum control and adaptability.
Reliability and protection

The inverter is equipped with extensive protective mechanisms, including reverse polarity protection, anti-island mode, insulation and short-circuit monitoring as well as surge protection. The protection class IP65 enables safe use outdoors, while the intelligent cooling and silent operation mode (<55 dB) provide for a maintenance-free operation.

Who is the Deye SUN-20K-SG01HP3-EU-AM2 for?

This inverter is Ideal for:
-Businesses with Hohem energy requirements and storage requirements
-Homeowners who seek maximum autarky with high-voltage technology
-Installers planning flexible, future-proof systems
-Project developers who implement AC-coupled retrofit solutions
-Off-grid systems with diesel generator or hybrid operation

FAQ on Deye SUN 20K High Voltage Hybrid Inverter

Which grid codes are stored in the inverter?

The inverter contains all common grid codes that can be changed directly in the menu "Setting → Grid". These include 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 as well as NRS 097-2-1 for South Africa. As a rule, this does not require additional NA protection once the appropriate country profile has been activated.
Which high-voltage memory units are compatible and how do ICH set up the BMS correctly?

Shared storage solutions include BYD HVS and HVM, Pylontech Force H1 and H2, Dyness Tower and the Deye GB-L Series. Each memory is stored with a specific setup number, which is selected in the menu "Battery → Lithium → Setup Number". 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.
How much PV power can ICH connect without the inverter clipping?

The data sheet allows up to 30 kW of DC input power, while the AC output power is 20 kW. This results in a DC/AC ratio of 1.5. In practice, a ratio of 1.1 to 1.2 is recommended, while WAS corresponds to approximately 22 to 24 kWp. According to experience, even with 26 to 28 kWp, there are only a few days of low losses due to clipping.
How loud is the converter operating?

In standby mode the inverter remains nearly silent because the fans start up at temperatures above 50 degrees Celsius or under longer load. In normal operation the noise level is below 45 decibels. A significant air noise is audible under full load, but remains below the maximum sound pressure of 55 decibels, as indicated by the manufacturer. The device is thus well suited for cellars and technical rooms.
Can settings and firmware updates be performed via APP?

Via the Deye Cloud or the SUN-APP all settings can be controlled remotely. This includes changes to load and export parameters, firmware updates for inverters, BMS and HMI, and a possible emergency shutdown of the device. The connection is done via WLAN, LAN or via the factory-installed Hotspot-Network. RS485, CAN and 4G sticks are also available for integrating external systems.
