Public notes
What this page is
This page is the public working note for Solis S6 Modbus monitoring, register verification, and follow-up corrections that matter in real-world use.
It is meant to be a cleaner place to keep the details that are easy to lose in a video description or scattered notes.
What to verify first
Before trusting any register map or dashboard value, verify:
- the exact inverter model and firmware
- the Modbus ID and serial settings
- word order and scaling assumptions
- whether the value is instantaneous, accumulated, or status-coded
- whether the register behavior matches the published documentation in live operation
Practical notes
- Documentation and field behavior do not always match exactly.
- Some values are straightforward to read, while others need scaling, signed-value handling, or trial verification against the inverter display.
- Firmware changes can affect which values are useful, stable, or even available.
- A register that looks correct at idle can still prove misleading under charge, discharge, export, or backup-load changes.
What this page will track over time
This page is where I want to keep the public-side notes for:
- confirmed useful registers
- scaling corrections
- status and fault interpretation notes
- monitoring and dashboard follow-up
- Grafana / Home Assistant / automation-related observations
Use this as working reference, not gospel
If you are building your own monitoring around a Solis S6, treat these notes as a practical starting point and verify against your own inverter behavior before relying on any one value for automation or protection logic.
