It has 798 installs sharing analytics, works locally and was last updated October 25, 2026. Solis Modbus is a HACS integration that connects Solis inverters to Home Assistant over a local Modbus link. It combines several register queries into single calls, which reduces overhead compared with the native Modbus integration. Connection is made either over TCP through a data logging stick or WiFi dongle, or over serial RS485. It provides number, select, sensor, switch and time entities, with separate fast, normal and slow poll intervals and a poll profile setting. Actions cover forcing battery charge or discharge, remote dispatch, programming scheduled dispatch periods, and reading or writing registers. A repair notice appears when the Solis datalogger is unreachable, and setup is done in the UI. Automatic summary of the README and code of Pho3niX90/solis\_modbus.

No vendor cloud in between. - **From the Marketplace**: Installed through the Marketplace, formerly HACS. - **Actively maintained**: Its author released or pushed a change in the last six months. ## Setting it up Install it from the Marketplace and restart Home Assistant, then add it under Settings, Devices and services. ### Select Connection Method - **Connection Type** ### Inverter Configuration - **IP Address** - **Port** - **Modbus Slave ID** - **Serial Port** - **Baud Rate** - **Byte Size** - **Parity** - **Stop Bits** - **Inverter Model** - **Fast Poll Interval (seconds)** - **Normal Poll Interval (seconds)** - **Slow Poll Interval (seconds)** - **Poll profile (how much of the register map is polled)** - **Extreme: also poll battery/load group (SOC, load, battery power)** - **Extreme: also poll Smart Port AC power (phase A/B/C, Smart Port models only)** Also asked when changing the connection. ### After setup - **Fast Poll Interval (seconds)** - **Normal Poll Interval (seconds)** - **Slow Poll Interval (seconds)** - **Poll profile (how much of the register map is polled)** - **Extreme: also poll battery/load group (SOC, load, battery power)** - **Extreme: also poll Smart Port AC power (phase A/B/C, Smart Port models only)** - **Suppress 'datalogger unreachable' repair issue while the sun is below the horizon** - **Automatically correct inverter clock drift (writes the inverter clock; turn off for read-only monitoring)** - **Inverter Model** - **Updated to V2 Firmware** - **Has PV (Solar Panels)** - **Has AC Coupling** - **Parallel inverter operation (multiple units)** - **Has Battery Storage** - **Has HV Battery Storage (100v+)** Texts from the code of [Pho3niX90/solis\_modbus](https://github.com/Pho3niX90/solis_modbus). ## Actions - **Write holding register**: Writes a value to a holding register Fields: Address, Value, Inverter - **Change the time of a entity**: Sets the time of the entity to the provided one Fields: Entity ID, Desired Time - **Read register**: Reads one or more registers and returns the raw values (register discovery / debugging) - **Force battery charge**: Force the battery to charge (hybrid inverters); reverts after the timeout - **Force battery discharge**: Force the battery to discharge (hybrid inverters); reverts after the timeout - **Stop force charge/discharge**: Cancel an active force charge or discharge - **Remote dispatch**: Real-time inverter dispatch: goal-seeking grid/battery control with inverter-side failsafe - **Stop remote dispatch**: Release dispatch — the inverter returns to normal operation immediately - **Program dispatch schedule period**: Write one of six inverter-resident scheduled dispatch periods (survives HA restarts) ## Troubleshooting - **Diagnostics**: Downloads a diagnostics file to attach to a bug report. - **Repair notices**: Notices it can show in Settings, Repairs: Solis datalogger unreachable ## At a glance - Kind: Marketplace integration - Category: [Energy](https://vulpo.app/integrations/category/energy.md), Solar and batteries - Brand: [Solis](https://vulpo.app/integrations/solis.md) - Number: 798 installs sharing analytics; 163 GitHub stars - Connection: Works locally - Upkeep: Updated in the last 6 months - Needs: Needs the Marketplace (HACS on 2026.10 and older) - Latest version: v4.4.0, last updated October 25, 2026 - Domain: `solis_modbus` - Source: - Issues: - Screenshot: https://vulpo.app/integrations-img/ddc66d8a51c82257.webp (from Pho3niX90/solis\_modbus's README) In Vulpo: Quick Toggle card, Select card, Chart card, Apple Watch, Control Center ## Other ways in for Solis | Name | Kind | Installs or stars | Connection | Upkeep | | --- | --- | --- | --- | --- | | [Solis Inverter](https://vulpo.app/integrations/marketplace/hultenvp-solis-sensor.md) | Marketplace integration | 1.7k installs sharing analytics | Needs the vendor's cloud | Updated in the last 6 months | | [Solis Cloud Control Integration](https://vulpo.app/integrations/marketplace/mkuthan-solis-cloud-control.md) | Marketplace integration | 506 installs sharing analytics | Needs the vendor's cloud | Updated in the last 6 months | | [Solis Cloud Monitoring](https://vulpo.app/integrations/marketplace/john-lazarus-homeassistant-soliscloudmonitoring.md) | Marketplace integration | 286 installs sharing analytics | Needs the vendor's cloud | Updated in the last 6 months | Independent directory, made by the developer of Vulpo.
