Hey thanks, that's exactly what I wanted to understand. @ControlsGuy25 Sorry if that was unclear, I was asking about Sunspec devices in general not really for a specific type of model. So in conclusion, Sunspec devices can be treated as a normal Modbus compliant device.

Hey! There isn't much that i could do better. My script are now polling the inverters constantly and as the forum suggested, every bit in the 16 bit registers 32008, 32009, 32010 have a different alarm meaning. So, I decided to poll the whole value inside the register and check if the value "as...

Hey thanks for sharing the document, I have indeed created a little config file listing all the alarm codes and their meaning. As I work with python scripts, the speed isn't very high and getting the alarm states can be a real hustle! In fact I poll the inverter constantly and look for a change...

Well there are multiple models and manufacturers that I work with. Most of them seem to have the same way of functionning. But for example i work with a Huawei SUN2000 22KTL. 3 register that I was talking about are: - 32008 - 32009 - 32010 which contain the "alarm" registers.

Hey thanks for looking into it! Can't believed I missed it, i'll try it out on the inverter next week! thank you very much :)

Hey! thanks for your reply, i am indeed using a modbus library (minimalmodbus), problem is, i didn't see anywhere in the code a way to read multiple registers at once? I will look more into it tomorrow, and i will check that link too! Thanks for your answer
