502 is in the inverter
connection wired
connected with anything else to the modbus interface of the inverter?
The SolarEdge does only allow one client connection being active on that interface.

No other connectionsā¦
In the full log I found:
2023-01-10 22:54:26.088 WARNING (SyncWorker_2) [homeassistant.loader] We found a custom integration solaredge_modbus which has not been tested by Home Assistant. This component might cause stability problems, be sure to disable it if you experience issues with Home Assistant
thatās why I asked if there is anything else that connects to your inverter 
But since you mentioned, that there are no other connections, I did not recommend the Modbus Proxyā¦
(which can be run as HA Addon - or standalone)ā¦

Hi, does anyone knows how often solaredge updates its meter values? Iām polling every second and I see changes in values only every 5 seconds. Is this limitation on the solaredge side?
I poll /3 sec with the integration and it updates that often. Looking at the SolarEdge app it is faster than 5 seconds even on that.
yes, inverter values are updating frequently, but the meter (external meter connected to inverter via modbus) values under m1_* are updated only every 5 sec.
is it a solar edge meter?
It might be, that the meeter does have a different update intervallā¦
I have Inepro pro380 modbus meter. The meter probably has high enough sampling rate, but the Solaredge registers get updated less frequently. Donāt know, just guessing.
I donāt know this device, but thereās a section on how to change the S0 Output rateā¦
7.10 S0 output rate
The energy meter is equipped with two pulse outputs (forward and reverse) which are optically isolated from the
inside circuit. It generates pulses in proportion to the measured consumption for purpose of remote reading or accuracy
testing. The pulse output is a polarity dependent, open-collector transistor output requiring an external voltage source
for correct operation. For this external voltage source, the voltage (Ui) should be lower than 27V DC. The maximum
switching current (Imax) is 100mA. To connect the impulse output, connect 5-27V DC to connector 18/20 (collector),
and the signal wire (S) to connector 19/21 (emitter). PRO380-CT only: the S0 pulses are always based on CT ratio 5/5.7.10.1 How to change the S0 output rate
ā¢ Scroll with the buttons to Program mode 3.
ā¢ Hold the right button for 3 seconds to enter the menu.
ā¢ Enter the 4 digit password: scroll with the buttons and select each digit 0-9, hold the right button for 3 seconds
to confirm each digit.
ā¢ Scroll to LCD page S0 output (S0 xxxxxx).
ā¢ Hold the right button for 5 seconds to enter program mode.
ā¢ The value starts blinking: select 10.000/2.000/1.000/100/10/1/0,1/0,01.
ā¢ Confirm the new setting by holding both buttons for 3 seconds.
ā¢ The LCD will show SET OK when the setting is confirmed.
thanks for investigating, but the pulse output is I think some different, similar to a blinking led which indicates consumption. Iām reading data from Solaredge Modbus over TCP
Sorry - I wasnāt checking what exactly the S0 āoutputā is related to.
It was the only area where I could find something about changing the output rate.
Iām aware that you are reading the data from the SolarEdge Inverter - the question here is: does the inverter limit the update frequency, does the inverter get the updates every x seconds from the meter - is there (maybe) a difference between solaredge meters and third party devices - or can this be changed by settings?
Honestly speaking: I donāt really care about update frequencies in that small time frameā¦
Iāve configured the update frequency round about once every 30 secondsā¦ thatās enough to provide a pretty good monitoringā¦
Also, I only have solaredge metersā¦
I have EV charger whose load balancing isnāt working ok, so I was trying to use meter values to limit EV chargerās current if goes over my power limit.
hmā¦ but do you really require to change the load balancing of your EV charger in a second interval?
For example:
My EV charger can switch between Solar Produced Energy - and Net Import.
In case that the Energy from Solar isnāt enough - or drop below a specific threshold, the Charger will stop charging.
But:
You should also consider that the Solar could just drop for a few Seconds or minutes due to clouds - in which case, I donāt want to do a āstop / start / stop / startā pattern.
So I would consider a 5second update Interval should still be pretty straight for such devices.
Solar has no role here, I just want to limit power usage of the whole house (charger), to prevent the breaker to flip off. For this, I would need even higher than a second refresh rate. Hopefully, the charger manufacturer will fix this soon, so I wonāt have to.
@squidnuts couple years late to the convo - but did you get an answer to this or figure it out? iāve got the same inverter (2 of them) and Iām not finding any great solutions to getting the data that i know is available on the solaredge monitoring website.
Good morning,
I installed āSolarEdge modbusā but I have some problems to receive information from my installation. I have a se5000h inverter without battery, I was able to connect via wifi (http://172.16.0.1) and I enabled the modbus TCP. I found the ip address and added the element in home assistant but all the sensors go back āunknowā:
I tried the āmodbus adressā 1 and 2 and with the āRead meter 1 data (only for meter models)ā checked or not. But with no result

I canāt seem to connect to the inverter. I tried connecting to the WiFi hotspot, but then I get a message that the password is invalid.
And when I try it via the QR code it does not recognize it.
Then I tried putting in the information myself, but then I get a message that it is unable to join the network.
What should I do at this point?
