Current Data Loggers

20 | These are currently being sold and supported by Solis: 21 |

S3-WiFi-ST

22 | 23 | ![S3](https://www.bimblesolar.com/image/cache/data/extra/xSolisW3-228x228.png.pagespeed.ic.hXxY06srvj.png) 24 | 25 | This seems to be the most common datalogger supplied with new systems. WiFi only. With it, you can: 26 | 27 | - Connect to SolisCloud (data at 5-minute intervals) 28 | - Control the inverter via SolisClud remote control (https://solis-service.solisinverters.com/en/support/solutions/articles/44002373796-inverter-remote-control-application) 29 | - Connect to Home Assistant using the read-only API integration at a 5-minute refresh: (https://github.com/hultenvp/solis-sensor) 30 | 31 | Without additional hardware or its firmware modification, you cannot directly connect to Home Assistant via Modbus TCP. 32 | 33 | To modify its firmware (do at your own risk): 34 | - ginlong-solis: https://github.com/hn/ginlong-solis 35 | 36 | You can get Home Assistant and Soliscloud without modifying its firmware if you follow this approach: https://github.com/alienatedsec/solis-ha-modbus-cloud 37 | 38 |

S2-WL-ST

39 | 40 | ![S2](https://www.solartradesales.co.uk/Cache/Images/Solis-Data-Logging-Stick-WL-4-Pin-03-500x500.jpg) 41 | 42 | Less common but available to purchase in the UK. This has WiFi and wired LAN. With it, you can: 43 | 44 | - Connect to SolisCloud (data at 5-minute intervals) 45 | - Control the inverter via SolisClud remote control (https://solis-service.solisinverters.com/en/support/solutions/articles/44002373796-inverter-remote-control-application) 46 | - Connect to Home Assistant using the read-only API integration at a 5-minute refresh: (https://github.com/hultenvp/solis-sensor) 47 | - Connect directly to Home Assistant using the core Modbus TCP integration (https://github.com/fboundy/ha_solis_modbus) over TCP port 502 48 | - Connect directly to Home Assistant using the SolaX Modbus TCP integration (https://github.com/wills106/homeassistant-solax-modbus) over TCP port 502 49 | 50 | if you connect directly to the inverter from Home Assistant you will lose SolisCloud connectivity unless you use additional hardware such as this approach: https://github.com/alienatedsec/solis-ha-modbus-cloud 51 | 52 |

Legacy Data Loggers

53 | These are no longer being sold or supported by Solis: 54 |

DLS-L

55 | 56 | ![DLS-L](https://statics3.solisinverters.com/uploads/image/5bdbe1df35b21.png) 57 | 58 | These are LAN-only devices. What you can do with them seems to vary according to serial number but may include: 59 | - Connect to SolisCloud (data at 5-minute intervals) 60 | - Control the inverter via SolisClud remote control (https://solis-service.solisinverters.com/en/support/solutions/articles/44002373796-inverter-remote-control-application) 61 | - Connect to Home Assistant using the read-only API integration at a 5-minute refresh: (https://github.com/hultenvp/solis-sensor) 62 | - Connect directly to Home Assistant using the core Modbus TCP integration (https://github.com/fboundy/ha_solis_modbus) over TCP port 3389 63 | - Connect directly to Home Assistant using the SolaX Modbus TCP integration (https://github.com/wills106/homeassistant-solax-modbus) over TCP port 3389 64 | 65 | You may be able to access SolisCloud and Home Assistant simultaneously with these dataloggers 66 | 67 | 68 |

They communicate using Modbus RTU encapsulated in the proprietary Solarman v5 protocol. To use these you need: 73 | 74 | - pysolamanv5: https://github.com/jmccrohan/pysolarmanv5 75 | - SolisMod: https://github.com/NosIreland/solismod 76 | - home_assistant_solarman: https://github.com/StephanJoubert/home_assistant_solarman 77 | 78 |

Other Harwdware

79 | 80 | There are a number of other direct ModBus approaches: 81 | 82 | - Using an [Elfin EW11 and GC-1201K](https://github.com/Jumpy07/Solis---SolisCloud-and-Home-Assistant) 83 | - Using [Waveshare Devices](https://github.com/alienatedsec/solis-ha-modbus-cloud) 84 | - Using a [Raspberry Pi as a RS485 bridge](https://github.com/mjh-homeassistant/solis-multiplexer) 85 | --------------------------------------------------------------------------------
