When your ecu-b is connected on the internet firmware is automatically updated. But unfortunately you can not check your firmware version in the app/online portal. But there is a workaround written in this forum to check current firmware.

When I look at the Apsystems app I currently have 19.3 kWh (6 panels east 6 panels west 10gr orientation). I don't see any panels with abnormal low output.
all the inverters have the same firmware versions

Here is my read out with many thanks to JMQ1961!
I have totally other firmware version then i read here on the forum.
I have DS3-L model -
I really appreciate all your effort, but this really looks too complicated for me

First we have be sure that the Modbus is working.
Make sure each inverter has its own Modbus ID
in the modbusdoctor the IPadress has to set to the IP of your ECU-R
Port is nomaly 502
than check if the connection is possible for each inverter. click on the connection disconnection field.
If the connection fails we can not read data.
If this is ok you can make further reading test.
Start with readind a single adress
example 40070 the result should be 101
or 40071 result 50
Please note, it will not work when the Panel is not producing Energy.
The inverter will use Power from Input 1 to be online, otherwise it is offline.
Do this test and let me know if it works.
Yes first stepped working

Ik wil zien wat ik kan doen. maar geef me wat tijd. niet vandaag.
Beantwoord mij alstublieft de volgende vragen.
ik heb enkele oplossingen.
heb je wat registers kunnen lezen bij de modbus-dokter?
1.
heb wel een oude pc of laptop die we kunnen gebruiken.
Ik wil je laten zien hoe je er een Linux-systeem op installeert.
2.
Als u een krachtige pc heeft, kunnen we ook een virtuele machine op uw pc draaien.
3. je kunt python op je pc installeren, geef me wat tijd ik heb om een documentatie te schrijven hoe het te doen.
de rest is eenvoudig.
Hoi,
l have not been able to connect and read data by modbus doctor. Do I have to type ecu op adres and change other input details?
lt think my pc is powerful enough to run virtual box.

Here is a screenshot how to use the modbusdoctor.
Do you know python programming?
If you have a old windows PC you can install Node-red on this PC.
I will help you to install and use my nodes.
Hi, no really a noob, so no python programming....maybe its better to contact on skype? peter_roovers@hotmail.com
