Support for regular string inverters

[debietim]

Hello

I am using this integrations for my Solis RHI 10kW Hybrid inverter and it works very good! I have also 2 regular inverters without battery. I't would be great if I can control this inverters also like I do with the Hybrid one.

But today I get an error when I try to setup one of these inverters.

Is there an option to support also non-hybrid inverters?

regards

Which errors are you getting?

[debietim]

I can add them (by IP address) but then I gat a "failed" message...

[Pho3niX90]

Which port are you using for them? Also, are there any other modbus software connecting to them? Lastly, do you know which wifi dongle is used with them?

[debietim]

I am using port 502 (was standard filled in)… i am using the same wifi dongle as on my hybrid inverter… (S2-WL-ST) No other modbus connection, only soliscloud…

Ah, you can't use this integration and Solis Cloud simultaneously - one or the other. Or set up an RS485 gateway - see the threads re. Waveshare

I know, but when i installed my hybrid with this integration, it automatically stopped on soliscloud… but now it don’t even start…

I have next to my Solis RHI 10kW also al Solis S5-GR3P8K string inverter. Now it would be very nice if I can control the Power Limit (value between 0 and 110%) via home assistant. Now I can only change this value via the SolisCloud platform. But when I use this integrations the device is not recognised... any chance that it can be supported in the future? I use the same datalogger as I use on the RHI 10kW inverter.

The Modbus register is different between the hybrid inverters and the normal grid-tied inverters. Here is an overview about the register: https://community.openenergymonitor.org/uploads/short-url/hfD6j9G7EvHVFtuh2HiujSVhgyG.pdf found in this conversation: https://community.openenergymonitor.org/t/solis-s6-pv-inverter-and-rs485-modbus/20507

There is a test version https://github.com/Pho3niX90/solis_modbus/releases/tag/string-test

[debietim]

Hello, I installed the test-version but was forced to roll back. The battery shows constant discharge of 139W. When tried to add a Solis String Inverter, this did not work. It connected, but no values (complete none) came thru..

Unfortunately the documentation I have found regarding the string inverters are unreliable to blindly code it. I would either need access to a system where I can do testing, or someone can continue from https://github.com/Pho3niX90/solis_modbus/pull/86 to make a PR

i can open a Port from the Elfin so you can connect to the Inverter over Modbus TCP !? but a little bit scared about security... is there a other Tip !?
