Register map(s) for this device, each at the trust rung it earned. Addresses are 0-based as on the wire. Word order and scaling are confirmed at the hardware-verified rung and at no rung below it.
Read + decoded cleanly over a real network vs an independent third-party Modbus test server (transport and framing; reads are remapped into the server's register window, so the map's own addresses are NOT exercised). Does NOT prove word order/scaling against the actual device.

⚠ Any damage caused to the inverter due to the use of any Modbus device is NOT covered by Sol-Ark's warranty. — Starkest reads only; we never write a control register.
| terminals | RJ-45 ports labeled 'RJ45_485', 'RJ45_CAN', 'RS-485', 'CAN', or 'Battery CAN Bus' depending on model, or terminal connectors for RS-485 and CAN. |
| A/B polarity | Pin 1/8: RS-485 B-, Pin 2/7: RS-485 A+ |
| termination | The inverter already has termination internally. A 120 Ohm termination resistor should be used on the master side of the communication cable. |
| connector | RJ-45 or terminal connectors |
| shield/ground | Ground MUST be connected between the inverter and master device (Pin 3 and Pin 6 on RJ-45). |
| wiring notes | Ground MUST be connected between the inverter and master device. Without ground connected, communication can be easily disrupted by external noise sources. |
| max registers/read | 125 |
| broadcast | not supported |
| protocol notes | The inverter only supports read operations. |
| serial register | 3 |
| identification notes | Serial number is ten ASCII characters stored in registers 3 to 7. |
| doc revision | V1.1 (2021-04-15) |
⚠ disputed: comms.notes: The inverter's Slave ID is 0x01. This cannot be changed — disputed by Sol-Ark 15K-2P-LV Installation Guide and SolarAssistant. On newer firmware versions, the Modbus SN (Slave ID) can be changed in the parallel options screen (it defaults to 00, but must be set to 01 or another unique ID for Modbus communication to function properly)
Each rung states what it proved and what it did not. Gray until proven; green is earned by hardware only.
If your device isn't here, upload its register map. Generation is free, and the connector keeps the rung it earns under testing.
To prove a connector against your own device, order hardware verification. If it doesn't verify, you don't pay.
Platform builders can license the verified library: machine-readable maps, the firmware matrix, API access.
