I have to integrate 2 sun 2000l, they are in the same network and obviously have two different ip’s. if I add some configurator:
sensor:
so it detects one, if I have to add the second ???
if I add one more
host: '192.168.1.95'
but by mistake. how should i do ??
@Emilv2
PLEASE… i need it too… 
Now, with last firmware SPC120 the SDongle have modbus over port 502… under FE connection
I’ve checked from my pc using (slave 1):
with this… we don´t need to have middle hardware to do it…
@Emilv2 great job… and you are very kind to share you excellent work
SUN2000-5KTL-M1
SDongle (firmware: SPC120) with Fast Ethernet cable connection
I made it with HA ModBus.
using “slave: 1” inside the sensor definitions
But i can’t have data @sec, it stops HA and i need to shutdown rpi
I’m working fine with scan_interval: 10 (but for me is poor)
modbus:
- name: Solar
type: tcp
host: 192.168.1.76
port: 502
sensors:
- name: Solar SunPower
slave: 1
address: 32080
unit_of_measurement: W
data_type: int
count: 2
scale: 1
precision: 1
scan_interval: 10
- name: Solar GridPower
slave: 1
address: 37113
unit_of_measurement: W
data_type: int
count: 2
scale: 1
precision: 1
scan_interval: 10
I have problems after sunset… it seems the inverter ModBus STOPS
Any one have some information about that?
Some configuration with FusionSolar?
Can someone explain how to update the dongle firmware?
Hello gieljnssns
Send an e-mail to [email protected] requesting the firmware package (zip file)
You need to detail your devices SN (Inverter and SDongle)
With FusionSolar connect you smartphone to WIFI SDongle AP, not the inverter SSID
(here, i needed to restart my inverter, the SDongle SSID only appear during startup, and it seems easier to use QR code)
After connection, select:
Configurations » Update firmware » select package file » and wait…
(keep your phone near the SDongle… 
)
When finish (about 10min) restart inverter
DC » OFF and after that AC » OFF
Wait 15 seconds… and AC » ON and DC » ON
Voilá
There is an issue in the ModBus integration which hangs the Lovelace interface:
Current workaround is downgrade to core-2021.4.6 and wait for 2021.6.
The issue comes from the upgrade of the pymodbus library which they have been updating lately so it is possible that Emil integration broke a while ago due to a similar reason.
Thanks… already downgraded…
I had made a custom component from this core/homeassistant/components/modbus at 2021.4.6 · home-assistant/core · GitHub
So you can stay on 2021.5.x
Hello,
could you please tell me, where you were able to download firmware SPC120 for the Smart Dongle?
My environment doesn’t offer v120 - only v118 - therefore Modbus TCP is not working via FE?
With Huawei ‘Device Upgrade’ I can only choose btw. v116 and v118… 
Would be great to share a link or the upgrade package itself!!!
Many Thanks!

I have a Sun2000 5KTL L1 (1 phase) inverter. The integration works perfectly, but I noticed that the following parameters are always 0:
grid_exported_energy
energy_used
Is this normal, or do I need to change to configuration to see those values?
I think those properties are available only when power meter is connected to the inverter. Mine shows some big values :), but i ignore them.
Grid exported energy 21474836.47
Grid accumulated energy 21474836.47
@Emilv2 any fix for this? I have set temporarly battery = false so that it works without battery info.

Thanks!
I had requested the new firmware, and I had received a zip file.
But the only way to update the firmware seem to be with an android phone.
So now I’m searching a phone to borrow from friends…
Do you have the latest version from Github? That error should have been fixed already.
For all the other questions/issues:
You can keep posting them here or on Github. I have seen a few things I can quickly fix and I’ll do that. Starting from June/July I should have some more time again and I’ll try to get all the other issues fixed then.
Ciao @Emilv2
Just redownloaded to be sure it was the last one, but I’m afraid error is still there:

Thanks in advance!
Oops, two more copy paste mistakes 
I fixed them, does it work now with the latest version from Github?
@Emilv2 Just updated sensor.py, but still same error
