These include, among others, 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 or RD 14 for Spain as well as NRS 097-2-1 for South Africa. Usually, no additional NA protection is required once the appropriate country profile has been activated.Which high-voltage batteries are compatible and how do I set the BMS correctly?Released storage solutions include, among others, BYD HVS and HVM, Pylontech Force H1 and H2, Dyness Tower as well as the Deye GB-L Series. Each storage unit is associated with a specific setup number, which is selected in the "Battery → Lithium → Setup Number" menu. 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. As compatibility is constantly changing, it is recommended to check with the manufacturer beforehand.How much PV power can I connect without the inverter clipping?According to the data sheet, up to 26 kW DC input power is allowed, while 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 in operation?In standby mode, the inverter remains almost silent, as the fans only start running at temperatures above 50 degrees Celsius or under sustained load. In normal operation, the noise level is below 45 decibels. At full load, a distinct airflow noise can be heard, but it remains below the maximum sound pressure of 55 decibels, as specified by the manufacturer. The unit is therefore well suited for basements and technical rooms.Can settings and firmware updates be carried out via the app?Via Deye Cloud or SUN-APP, all settings can be operated remotely. This includes changes to charging and export parameters, firmware updates for inverter, BMS and HMI as well as a possible emergency shutdown of the unit. The connection is made via WLAN, LAN or via the factory hotspot network. Additionally, RS485, CAN and 4G sticks are 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 power, integrated LCD touchscreen and two MPPT trackers.1 x wall mount bracketA robust metal mounting rail for secure attachment of the heavy device to a load-bearing wall.1 x Wi-Fi stick (data logger)A plug-in communications module for connection to the Internet for remote monitoring via Deye Cloud or Solarman App.3 x current transformers (CT - Current Transformer)External folding current transformers for measuring energy flows at the house connection, necessary for zero feed-in and self-consumption optimisation.1 x set of PV connectors (MC4-compatible)The necessary sets of DC plug connectors (plus and minus) for connecting the PV strings to the inverter.1 x set of battery connection plugs (high voltage)Special high-voltage plug connectors for the safe electrical connection of a compatible HV battery storage unit.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 dowels)A set of stainless steel screws and heavy-duty dowels for the proper installation of the wall bracket.1 x User ManualA printed manual with detailed installation instructions, circuit diagrams and safety information.

The Deye BOS-G Cable Set is the essential connection kit for the installation and commissioning of the Deye BOS-G high-voltage battery series. This set establishes a secure connection between the battery tower (cluster) and the hybrid inverter. It includes all the necessary cables for power transmission (DC) as well as the intelligent communication between the Battery Management System (BMS) and the inverter.With a standard length of 5.0 metres per cable, this set offers maximum flexibility in choosing the location of the battery storage and inverter, even if they cannot be mounted directly next to one another. All components are designed for the high voltages and currents of high-voltage systems and guarantee low-loss energy transmission.Key features at a glanceComplete set: Contains all cables required for connecting a BOS-G battery cluster to the inverter.Long reach: The generous cable length of 5.0 metres enables flexible installation in utility rooms or garages.Optimised cable cross-sections: The DC power cables are dimensioned for the high loads of high-voltage systems in order to minimise heating and voltage drops.Secure connectors: Pre-assembled connectors ensure error-free polarity and quick plug-and-play installation.Interference-free communication: The shielded communication cable ensures precise data exchange between the BMS and inverter.Industrial quality: Robust insulation and high-quality materials for lasting reliability in stationary storage applications.Components of the set1x EPCable 5.0 (Positive Power Cable)The red DC power cable for connecting the positive terminal between the Battery Control Box (BMS) and the inverter.1x ENCable 5.0 (Negative Power Cable)The black DC power cable for connecting the negative terminal between the storage cluster and the inverter.1x ECOM Cable 5.0 (Communication Cable)The dedicated data cable (RJ45-based) for CAN/RS485 communication, allowing the inverter to read the battery data in real time.Installation & safety instructionsStrain reliefWhen routing the 5-metre cables, make sure they are laid without kinks and fixed to solid structures to avoid mechanical tension on the connections.Secure plug connectionEnsure that the power connectors click audibly into place. A loose connection can lead to arcing and overheating under high loads.Connection sequenceAlways connect the communication cable (ECOM) first and check the correct assignment before energising the DC power cables. Features ModelDeye BOS-G Cable Set Cable type**DC high-voltage power cable** Max. voltage**1000 V DC** Max. current**125 A** Set contentsPositive cable, negative cable, communication cable CompatibilityDeye BOS-G (HV) series Cable length5m Safety standardFlame-retardant according to UL94-V0 Special featureIncl. **BMS-CAN/RS485** data cable  FAQs about the Deye BOS-G Cable SetCan I shorten the cables myself?Not recommended. The cables are factory-fitted with special high-current crimp contacts. Manual shortening without professional tools can increase the transition resistance and compromise the safety of the system.Is this set also suitable for the BOS-A series?Only to a limited extent. Check the plug compatibility on the control box beforehand. While the communication protocol is often identical, the physical DC connections can differ between different model series.Why is the ECOM cable so important?No communication, no function. In a high-voltage system, the BMS specifies to the inverter the power at which charging or discharging may take place. Without the ECOM cable, the inverter will refuse to operate for safety reasons.
