FAQs about the Deye Sun 20K High-Voltage Hybrid Inverter

Which grid codes are stored in the inverter?

The inverter contains all common grid codes, which can be switched 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 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.

The Eastron SDM630-M is a modern and multifunctional digital energy meter for three-phase networks, designed for comprehensive monitoring and analysis of electrical parameters. Thanks to its integrated Modbus RTU interface, it can be seamlessly integrated into building automation, energy management or photovoltaic monitoring systems. As a direct-measuring meter up to 100 amps per phase, it offers precise data acquisition for a wide range of applications in commercial, industrial and demanding private households.Highlights at a glancePrecise measurement: Reliably measures a wide range of electrical quantities (kWh, kvarh, kW, kvar, kVA, P, F, PF, Hz, dmd, V, A, THD).Modbus RTU interface: Enables simple remote reading and integration into higher-level systems via RS485.Multifunctional: Suitable for energy monitoring, cost centre billing, load management and PV system monitoring.Direct measuring up to 100A: No external current transformers required for currents up to 100A per phase, simplifies installation.Compact DIN rail format: Simple and space-saving installation in standard electrical distribution boards (4 modules wide).Comprehensive energy monitoring for professional applicationsThe Eastron SDM630-M is the ideal instrument for detailed recording of energy consumption and generation. It enables the precise monitoring of total consumption, individual machines or circuits as well as the recording of energy generated by a photovoltaic system. Thanks to the measurement of active and reactive energy in both directions (import/export), it is perfectly suited for monitoring PV systems with self-consumption. Its data forms the basis for energy efficiency measures, internal cost allocations or the monitoring of load profiles.Precise measurement and flexible integrationIn addition to active energy (kWh), this energy meter also measures reactive energy (kvarh), active power (kW), reactive power (kvar), apparent power (kVA), current (A), voltage (V), frequency (Hz), power factor (PF) and total harmonic distortion (THD) for voltage and current. The integrated Modbus RTU interface via RS485 enables all these values to be queried by systems such as data loggers, PLC controllers or energy management software. Direct measurement up to 100A eliminates the need for complex installation and configuration of external current transformers in many standard applications.Simple installation and operationThe SDM630-M is quick and easy to install on a standard DIN rail in electrical distribution boards.

There are also variants with pulse outputs (e.g. SDM630-V1/-V2), with M-Bus interface or as MID-calibrated versions for billing purposes (SDM630-Modbus-MID).Do I need external current transformers for this meter?No, this model is designed for Direct measurement of currents up to 100 amperes per phase. No external current transformers (CTs) are required as long as this current range is not exceeded. Special CT meters (e.g. SDM630MCT) are available for higher currents.Is this meter suitable for official billing (e.g. with the energy supplier)?No, this standard model is usually not MID-calibrated and must therefore not be used for billing to the nearest kilowatt hour. It is primarily intended for monitoring purposes and internal cost allocation. For billing purposes, you need a variant with MID approval (e.g. SDM630-Modbus-MID).How is the data read out via Modbus?To read out the data, you need a Modbus master (e.g. a data logger, a PLC, a Raspberry Pi or a PC with appropriate software and an RS485 interface). The master sends queries to the address of the meter in the RS485 network and reads the values from the defined Modbus registers. The register assignment can be found in the manual for the meter.
