Solinteg | Solax Modbus integration

[ziat007]

Battery charging

• Can be throttled to force export by number.solinteg_battery_charge_current_limit

Charging/Discharging into grid:

• Solinteg invertor integration does not have Times charge/discharge.
• It can be achieved by changing the select.solinteg_working_mode to
• General mode as standard. (feed in at 100% SOC, or limited by number.solinteg_battery_charge_current_limit)
• UPS mode as forced charging.
• Economy mode - in the app set up all times to be discharging.

Can you set a Target SOC for a timed charge or discharge period?

• No

Does the inverter report SOC in kWh or Percent?

• SOC sensor.solinteg_battery_soc

Can you set a Reserve or Backup SOC?

• number.solinteg_battery_soc_min_offgrid
• number.solinteg_battery_soc_min_ongrid

Constants

• sensor.solinteg_battery_rated_capacity
• Max Battery Power 7kwh
• Max Inverter Power (if different from Battery) 10kwh
• Entity IDs for the following sensors:
• Cumulative Daily Energy

    - sensor.solinteg_house_energy_today
  import_today:
    - sensor.solinteg_grid_import_today
  export_today:
    - sensor.solinteg_grid_export_today
  pv_today:
    - sensor.solinteg_energy_generation_today

Current Power / Battery Readings

• Meter power: sensor.solinteg_measured_power (positive feed in, negative buy from grid)

  battery_power:
    - sensor.solinteg_battery_power
  pv_power:
    - sensor.solinteg_pv_power_total
  load_power:
    - sensor.solinteg_house_total_load
  soc_percent:
    - sensor.solinteg_battery_soc

Inverter clock (if available) - if so let me know the format it reports in

• no

So far most things seem to be working.

 # Service for start/stop
  charge_start_service:
    service: select.select_option
    entity_id: select.solinteg_inverter_working_mode
    option: "UPS"
  charge_stop_service:
    service: select.select_option
    entity_id: select.solinteg_inverter_working_mode
    option: "General"
  discharge_start_service:
    service: select.select_option
    entity_id: select.solinteg_inverter_working_mode
    option: "Economic"
  discharge_stop_service:
    service: select.select_option
    entity_id: select.solinteg_inverter_working_mode
    option: "General"

• Charge from grid mode can use UPS invertor settings (charges to 100%)
• Discharge mode can use Economic mode, manually set in the app to force export 00:00-23:59

One thing I am struggling with is freeze export. Battery is controlled via charge/discharge current limit. But predbat changes to mode to Force export instead.
How can I change this behaviour to just use General mode and limit the current?

seems like I was missing this:

  discharge_freeze_service:
    entity_id: select.solinteg_inverter_working_mode
    service: select.select_option
    option: "General"
