SH10RT command-line tools

Find Sungrow SH10RT inverters on your network and inspect their measurements in the terminal. This independent community project provides command-line tools, troubleshooting guidance and a Modbus register reference.

Python 3.10 or later is required. Device identity checks currently accept code 3599 (SH10RT-V112 in the reviewed protocol), rated 10 kW. Other SH10RT variant codes require separate validation; see model identity.

Commands

Command	Purpose	Device access
scan	Find interfaces on an explicitly selected private subnet	Read-only discovery; no login attempts
values	Show PV tracker power, AC/grid, battery and other supported measurements	Input registers only; terminal report or JSON Lines
status	Inspect identity, state, Start/Stop and alarm words	Input and holding-register reads
start	Preview an explicit Start for one stopped device	Preview by default; exact serial and --execute required for a write

Quick start

Download or clone the whole repository and open a terminal in its directory. The executing computer must be able to reach the inverter network. Replace all example IP addresses with your actual private network addresses.

Find interfaces:

python3 scripts/sh10rt_lan.py scan --network 192.168.1.0/24

Read measurements:

python3 scripts/sh10rt_lan.py values --host 192.168.1.100 --transport modbus

Read two interfaces, or request machine-readable output:

python3 scripts/sh10rt_lan.py values --host 192.168.1.100 --host 192.168.1.101 --transport modbus
python3 scripts/sh10rt_lan.py values --host 192.168.1.100 --transport modbus --json

Each host is read once and the command exits. Requests are paced; allow at least 11 seconds per inverter, longer for unsupported or timed-out blocks. Multiple hosts share the supplied unit and transport. Compare serials before treating two addresses as separate inverters.

Inspect the software operating state and Start/Stop setting:

python3 scripts/sh10rt_lan.py status --host 192.168.1.100 --transport modbus --unit 1

On Windows, replace python3 with py -3. Modbus TCP requires no extra packages. Authenticated WiNet HTTP/WebSocket access uses --transport winet and the optional dependency in scripts/requirements.txt; see requirements.

Platform launchers

Platform	Terminal launcher
Linux	./sh10rt.sh
Windows	sh10rt.cmd
macOS	./sh10rt.command

Launchers accept the same command arguments. Without arguments in an interactive terminal, they offer a text menu for scan, status, measurements and Start preview. They require Python and do not bundle an executable runtime. Windows and macOS native execution still need validation on those operating systems.

Understanding measurements

• PV tracker power is calculated as voltage × current. Physical strings sharing one tracker cannot be measured separately through these fields.
• PV DC and AC output are separate measurements, sampled through separate requests.
• Missing or invalid readings appear as unavailable, or null in JSON. Partial block failures are reported and return exit code 2.
• Battery telemetry and meter-derived values are gated by available communication-status data. A reported SOC alone does not prove charging.
• Shared grid/load readings must not be summed across inverters. Battery power/current retain their reported signs; confirm direction against the relevant firmware documentation.
• Fault labels refer to register bits, not numeric iSolarCloud fault codes. Missing alarm data is not an all-clear result.
• Direct BMS unit-200 entries are included as reference material; the CLI does not query them.

The CLI does not configure grid protection, export limits, battery charging, parallel roles or firmware. Its guarded Start procedure is documented separately in the CLI guide.

Documentation

Guide	Contents
Network scripts	Discovery, terminal measurements, WiNet, launchers, status, guarded Start and exit codes
Modbus registers	Addresses, types, scaling, status/flag meanings, model and firmware caveats
Modbus examples	Input-only reads, TCP frames, word order, signed values, JSON and CSV usage
Register JSON	83 typed register entries/ranges and eight selected fault bits
Troubleshooting	Connection failures, partial measurements, startup and low production
Manual startup references	Manufacturer documentation of software startup
Parallel operation	Device identity, shared measurements and configuration boundaries
Contributing	Development checks and public repository scope

All public examples and tests use synthetic data. Store real credentials, identities, network addresses, telemetry and service records under the ignored private/ directory or outside this checkout. Contributions should contain generic SH10RT help and reusable CLI functionality.
