abb_aurora_solar_inverter_library's Issues

no result from readDSP

I am implementing your library within my ESPHome application to connect to my ABB PVI-3.0-TL-OUTD-S. The readCumulatedEnergy seems to work (although not use the values are correct.) however the readDSP seems not to to work and state.readState is always 0. Any pointers on what should I check to get it working?

Meaning of the multipler in the inverter struct

Hi,

I see that in the InverterModel struct there is a variable called multipler. The values of this variables are constants defined in the following conversion function that takes the model ID and coverts it to the model name.

I'm not finding any reference to that values in the documentation, where does that numbers come from and what is their meaning?

Thank you and congrats for the great code!

blog not respons

i'm sorry mr can you share code about rs 485 https://mischianti.org/interface-arduino-esp8266-esp32-rs-485/

its happen in your blog

Communication problem

Hello, I am trying to read the power output of my inverter (ABB PVI-3.0-TL-OUTD) and I flashed your example code as it is, changing the pin mapping.
The only change I made to the code is to replace the calls to freeMemory with ESP.getFreeHeap(), as for some reason the code is not compiling for me on the ESP if using the MemoryFree library.

I am using a Wemos D1 mini board, connected to an RS485 to TTL Arduino board (MAX485) through a level shifter.
Connections are made as following:

[Board to module]
rxPin (0) -> RO
txPin (5) -> DI
sCCPin (4) -> RE, DE

[Module to inverter]
A -> +T/R
B -> -T/R
RTN -> GND
LNK disconnected

Output I'm getting on the console:

15:54:43.429 -> INVERTER 2

The inverter address is correctly set and the terminator resistance is set to ON.

I must be missing something, thank you for your help.

"Current day Energy" not resetting each day

It's certainly not your software related but I'm lost! :-(

On one of mine 3 aurora inverters ET (Current day Energy) reading on some random day starts unusually high (79170) even when previous day last reading was (32966). Seems like ET is not reset correctly. Faulty firmware is C.0.0.6. Other two inverter with C.0.0.5 work fine.

Any ideas on how to solve this?
Thank you! Grazie!

Manage multiple inverters

The only way to manage multiple inverters is to instantiate more Aurora objects when the only thing that changes is the inverterAddress, so a setter for this value would be useful
