Can you update your Solis inverter through this integration? about ginlong-solis HOT 11 CLOSED

@hcouplet Just pushed 4435415, which includes your code (with small modifications, I think the lambdas aren't needed).

In my opinion, there is nothing to stop all the things that can be set via ModBus (holding registers, see INV/ESINV register maps) from also being realised via this solution. For example, the inverter's internal clock is synchronized via NTP for INV type inverters.

I have 3 solis inverter and I must limit the power injected to grid to max 10Kw. (Belgium regulation).

I have a P1 house counter that report the power injected to the grid.
So I am updating inverters power limit to do that. ( I know that I can limit the power by connecting the meter to the inverter but this way I can define the balance myself)

Here is what is working for a solis S6.
By default it is set to 110% . One I change to value, it change the power generated.

number:
    ## Set ≈ limit
  - platform: modbus_controller
    modbus_controller_id: modbus_master
    id: solis2_set_power_limit
    name: "Set Solis2 Power limit"
    address: 3051
    unit_of_measurement: "%"
    register_type: holding
    value_type: S_WORD
    mode: box
    step: 0.5
    entity_category: config
    skip_updates: 100
    min_value: 0
    max_value: 110
    lambda: "return  x / 100; "
    write_lambda: |-
      int16_t limit = x * 100;
      ESP_LOGI("main", "Set Power Limit %d", limit);

      //Send power limit        
      esphome::modbus_controller::ModbusCommandItem set_payload_commandValue = esphome::modbus_controller::ModbusCommandItem::create_write_single_command(modbus_master, 3051, limit);
      // Submit the command to the send queue
      modbus_master->queue_command(set_payload_commandValue);
      return {};

@hcouplet, great, thanks for sharing your configuration!

Does it actually work? Solis docs say that for reg 3052 to work, you need to set 3041 to 0x03 (fixed power factor) -- did you change this value? My reg 3041 is factory default = 0x00.

from ginlong-solis.

Yep it's working fine.

I tried other registries (i.e. 3081 with 3070) to set the absolute limit but they didn't worked.
This one was in the inverter menu and is limited on the inverter to max 110%. I was also limited to 110% max with the modbus.
I didn't had the 3041, I guess it's by default activated.
Anyway, if the inverter deliver 4000W, setting a value of 10%, instantanely changed the delivery to 500W (I have a 5K inverter). Also changing on the inverter, changed the value on HA and vice-versa.

I can check tomorrow during day time my 3041 value.
I have still lo check with my solis hybrid : I have two S6-GR1P5K and one RHI-6K-48ES-5G. (this is a DIY install).
Once I have the working value, I will post it here.

3041 is set to "No response mode" on my inverter. So the register 3052 don't seem to use the 3041.
Here is the select I did :

select:
  - platform: modbus_controller
    name: "Working Mode"
    address: 3040
    value_type: S_WORD
    optionsmap:
      "No response mode": 00
      "Volt–watt default": 01
      "Volt–var": 02
      "Fixed power factor": 03
      "Fix reactive power": 04
      "Power-PF": 05
      "Rule21Volt–watt": 06

For the register 3052, On the inverter it's on the menu :
Advanced Settings / 0010 / Power Control / Set Output Power

Maybe the doc is not correct, I am wondering if I am not changing the register describe at 3050 :

This would make sense with the multiply by 100 (value max 11000) and it does not depend on other register.

May be we need to do plus +1 instead of -1 as explained in the doc ? :

Anyway I confirm that it's working great and the power is adjusted down and up directly : I can go down to 500W and the second later it goes back to 4500W

from ginlong-solis.

According to this Solis FAQ 'Set Output Power' is a volatile Setting (= reset during reboot) and 'output_p mit restore' is a permanent setting. Maybe each of this settings is set in different ModBus registers.

Maybe the doc 'This function is only available for working mode 03 Fixed power factor' only relates to the last part of the setting explanaition (set negative values). Just a guess.

from ginlong-solis.

This is good to know. The one I am changing is the 'Set Output Power' and not the one with restore as also available in the inverter menu. For what I want the one in RAM is better so I can update it often without risking to burn the flash with too many write.

from ginlong-solis.

Here is the code for solis hybrid. I tested on Solis RHI-6K-48ES-5G (firmware 3D0037).

To change output power. This is the value in RAM, so there is no write count limitation and it will be gone after reboot.

number:

• platform: modbus_controller
  modbus_controller_id: modbus_master
  id: set_power_limit_fixed
  name: "Set Power limit"
  register_type: holding
  address: 43052
  value_type: U_WORD
  unit_of_measurement: '%'
  entity_category: config
  icon: mdi:percent
  skip_updates: 10
  mode: box
  min_value: 0
  max_value: 110
  multiply: 100

Grid AC voltage is also useful for me :

• platform: modbus_controller
  modbus_controller_id: modbus_master
  name: AC Voltage
  device_class: voltage
  state_class: measurement
  unit_of_measurement: V
  register_type: read
  address: 33073
  value_type: U_WORD
  accuracy_decimals: 1
  filters:
  • multiply: 0.1

For S6 non hybrid, I am using :

• platform: modbus_controller
  modbus_controller_id: modbus_master
  name: AC Voltage
  device_class: voltage
  state_class: measurement
  unit_of_measurement: V
  register_type: read
  address: 3035 # = 3036 - 1
  value_type: U_WORD
  accuracy_decimals: 1
  filters:
  • multiply: 0.1

Here is the doc I used for the hybrid :
RS485_MODBUS-Hybrid-BACoghlan-201811228-1854.pdf

Here is another one interesting on the hybrid model. Setting the backflow power.
This is not in the documentation, but a guy discovered it (see https://diysolarforum.com/threads/solis-s5-various-issues.52383/#post-674717)

I tested it and confirm it's working on my inverter.

• platform: modbus_controller
  modbus_controller_id: modbus_master
  id: set_backflow_power
  name: "Set Backflow Power"
  register_type: holding
  address: 43074
  value_type: U_WORD
  unit_of_measurement: 'W'
  icon: mdi:transmission-tower-export
  entity_category: config
  mode: box
  multiply: 0.01

from ginlong-solis.

@hcouplet I added backflow power setting with 33a4d83 . Can you please double check, I slightly modified your code:

• add min value
• changed icon to tower-import, export from inverter is import to the grid, right?
