I thought about the same, but mine is always 100% as soon as the inverter turns on
Good afternoon…
I have problems connecting to the module that I have via cable… the ip is correct, it responds to ping, but if I telnet to the ip with ports 502 and 6607, neither of them answer me… those are those ports, right? I think 502 for wifi and 6607 for cable.
Thanks in advance

Hi Fredrik,
I’ve looked around (finally managed to change my Huawei installer password today and gained access to the battery configs) and it appears I want to do the same as you did regarding the timed charge and discharge of the battery. My reason is that we have a 4 hour period of cheap electricity at night and if I want to charge my battery from the grid I don’t want my EV to take all that charge when the battery SOC state is reached first. Hence I can see that setting the max discharge parameter to 0 during that 4 hour period would work well. My question to you though is whether the TOU mode needs to be set for this to occur? or can this be achieved despite the battery working mode being set to “Maximise Self-Consumption”?
Thanks,
Mike.
Somehow it reverted and is reporting better values.
Since you’re in NZ too, do you struggle with the time offset and NMS vs NTP time source?
It looks like Huawei doesn’t want me to stick with NTP and reverts the time server to their faulty NMS server every time I set it to NTP.
My integration works great, but i have an error in the logs:

I have a SUN2000-6KTL-L1 connected to a 6kw Luna battery pack.
using this code:
- sensor:
- name: energy_pv
#friendly_name: "PV Energy"
unique_id: "PV Energy"
state: "{{ (states('sensor.inverter_total_yield') | float) - (states('sensor.battery_total_discharge') | float) + (states('sensor.battery_total_charge') | float)}}"
device_class: energy
state_class: total
unit_of_measurement: kWh
- name: energy_pv_daily
#friendly_name: "PV Energy daily"
unique_id: "PV Energy daily"
state: "{{ (states('sensor.inverter_daily_yield') | float) - (states('sensor.battery_day_discharge') | float) + (states('sensor.battery_day_charge') | float)}}"
device_class: energy
state_class: total
unit_of_measurement: kWh
The energy dashboard create this graph:
But as you can see there is a negative solar production during the night.
How can I solve this issue?
Hi!
Just want to know if someone has trouble with the huawei solar integration, that’s two days that doesn’t work at all. Already opened a bug issue on GitHub .
- name: energy_pv
unique_id: "PV Energy"
state: "{{ (states('sensor.inverter_total_yield') | float) - (states('sensor.battery_total_discharge') | float) + (states('sensor.battery_total_charge') | float)}}"
device_class: energy
state_class: total
unit_of_measurement: kWh
Add this as a template and use it instead
Is there any solution for connecting two Huawei inverters to home assistant if a connection between them is in cascade? master is with a dongle which has wifi or LAN connection?
for now I can only see and read all data from master inverter and metar .Thanks
This is the same code that I posted.
Need a little bit of help.
One of my inverters constantly disables the IP integration so I do not have access (I think it my provider that monitor everything is doing something)
So I bought a EW11 and connected it following this guide: Connecting to the inverter · wlcrs/huawei_solar Wiki · GitHub
But I can’t get any data the integration fails to read data from the Inverter thru EW11.
When running QModMaster I can read register 30000 sometimes, I can have 4-5 timeouts then I get the values.
The setup is 2 inverters a battery and a backupbox connected to this ModBus.
If I try to read battery data 37762 I get it after a few tries.
Can I do anything to either set more tries or anything on the EW11 to get it working better

Hey all in the group. Just thought I’d report that I got the integration working OK. To me the dongle is extremely stable. Im sure it has a lot to do with your router rater than the dongle itself. This is my screen so far. Unfortunately I do not have usage metrics and return to grid metrics to report so this is it for now unless anyone has some suggestions. At this stage there is no point using HA energy tab. I plan to install the Huawei meter in the switchboard which should yield further metrics.
Thinking about it, the only thing I can add is you need to have an installers account when you log into the unit using the SUN2000 app. That’s the only place you can turn on the necessary levels to access Modbus data correctly I believe ar at least I couldn’t find them in the FusionSolar app.
EDIT: If you want rock solid performance after modifying any parameters with the SUN2000 app, make sure you go to Communications Settings/Router and enter the password to your router into the inverter again. That should guarantee rock solid performance.

This worked pretty well for my 2 inverters with the Dongle. My only problem is, that the sensor refresh is not synchronized:
After request of the sensor refresh it takes different times for Power Meter, Battery, Inverter 1 and Inverter 2.
This is a problem for my calculated “house active power” and for power indicated automations.
@wlcrs: Is there a solution to synchronize the refreshing?
I already tried to refresh via automation, but the refreshing takes different times for the inverters etc …
When setting up the integration you need to specify 2 IDs, separated by comma.
i.e. 1, 16 (or whatever your IDs are, usually master is 1).
I am using cable connection via Dongle and port is 502 as well.
However you need to access the inverter (or dongle) as Installer (use Sun 200 App, connect to WLAN of Dongle/Inverter), then enable Modbus TCP with all rights in order to use this integration.

I am using Node-RED for my home automation. I already get the data from the solar system through the FusionSolar API. Now I want to be able to set the battery operation mode and switch between TOU and ‘maximum self consumption’ from the api.
I can not find any documentation to do so. How did you manage in HA ?
how to find which IDS is on the slave inverter ??? thanks
I think somewhere in the inverter configuration via Fusion you might see it.
I know several people that had 1 for master and 16 for slave. You might want to try that.
