The inverter supports heavily unbalanced phase loads, allowing up to 50% of its nominal power (5 kW) to be drawn on a single phase. For capacity expansion, up to 10 units can be connected in parallel using the Parallel A and Parallel B CAN interfaces in a daisy-chain topology. In this configuration, battery CAN communication (BMS port) is connected exclusively to the Master unit, while Modbus addresses are assigned sequentially to the Slaves.
The multifunctional GEN Port fundamentally alters system topology. When used for AC Coupling (Retrofit) alongside the Heckman Genswitch, the hybrid inverter actively controls the attached On-Grid string inverter. In Off-Grid mode, the Deye unit dictates the string inverter's shutdown to prevent energy storage overcharge, whereas in On-Grid mode, it allows the string inverter to operate without interference. For fire safety (P.POŻ compliance), killing power to the Load port requires physically cutting both the grid supply and the energy storage DC feed.
By default, the system uses the CHINT DTSU 666 meter. However, if the grid measurement point is more than 30 meters from the inverter, installation requires an external Smart Meter (e.g., Eastron SDM Modbus V2) utilizing RS485, Wi-Fi converters, or PLC (Power Line Communication) over existing phase wires. Grounding architecture depends on local regulations: the inverter features an internal relay that bonds the neutral and PE on the backup side during island mode, remaining open during grid-tied operation.
Ideal for
- ✓ Installers designing parallel systems (up to 10 units) with centralized Master-BMS communication
- ✓ Facilities requiring Retrofit (AC Coupling) using the GEN port or Heckman Genswitch
- ✓ Sites with grid measurement points exceeding 30 meters, requiring PLC/RS485 Smart Meters
Technical FAQ
What are the DC wiring specifications for the 10 kW model?
The energy-storage inputs require 50 mm² (2/1 AWG) cables. The energy storage connector bolts are M10 (15.3/16 mm). If parallel energy storage connection without busbars is necessary, they must be cross-wired (positive potential to the first module, negative to the last) to ensure balanced charging of the 51.2 V system.
How does the Deye scheduling differ from EcoBSS EMS firmware?
Standard Deye firmware requires manually toggling the 'Selling First' parameter, meaning you cannot schedule buying and selling in the same timeframe. EcoBSS firmware allows unified daily scheduling for selling, buying, and auto-consumption without requiring an external Energy Management System (EMS).
How is the CT clamp and Smart Meter wiring configured?
If the LCD shows incorrect load power, the CT arrow is reversed, or the black/white wires must be swapped. CT-L1 (pins 3,4) is used for 'zero export to CT' on L1. For external meters (Meter 485 port), standard RS485 or PLC converters are required for distances over 30 m.
How does the N-PE configuration work in Off-Grid mode?
The inverter has an internal relay. In grid-tied mode, the relay is open. In backup (island) mode, it connects Neutral and PE. A 'Separated N' connection method is required to keep N and PE isolated during an inverter fault, which is mandatory for strict off-grid compliance in certain jurisdictions.
