Try already present profile for different INVT inverter and if it does not work you have to contact your manufacturer to give you modbus documentation for your model.

Try already present profile for different INVT inverter and if it does not work you have to contact your manufacturer to give you modbus documentation for your model.

I contacted the provider and they sent me the API but I don't know how to use it. Can you help me?

[davidrapan]

I don't know what do you mean by "API".

[thaibacgiang]

I don't know what do you mean by "API".

means the manufacturer sent me the API

[davidrapan]

For what? Be specific.

[thaibacgiang]

For what? Be specific.

Currently, no developer has put that Imars inverter device into hass for monitoring! Now they send me the API to develop and put it into hass for monitoring, similar to LUXpower

[davidrapan]

This integration focus is on direct communication with the inverter via modbus using solarman protocol (cloud-free).

Yes! Now I want to connect the inverter to the hass for convenient monitoring and real-time updates.

[davidrapan]

I'm afraid we don't understand each other.

Anyway, maybe it's worth the shot to just try install this integration and configure device w/ invt_xd-tl.yaml profile. Maybe your device uses the same register addresses. 😉

[thaibacgiang]

invt_xd-tl.yaml

how to put it in the options config? i searched but can't find the invt_xd-tl.yaml option

[davidrapan]

It's not yet part of released version. You can manually copy the file from repository to appropriate folder of your installation.

Testing invt_xd-tl integration for this model (MG5TKL-2M and stick LSW-3) doesn't seems to work due to some wrong modbus addresses, unfortunately I was not able to find in Internet any documentation regarding this model. Here it's the log

[davidrapan]

This is unfortunate, but maybe it would be worth trying some of the other profiles too?

Try to contact iNVT and ask them for modbus rtu documentation.

[brainstormi]

I tested with all of them without luck. Just requested the info to iNVT too although I don't have big hopes. In parallel I'm trying to run a register scan with pysolarmanv5 just out of curiosity, although I can't get it completed due to different timeouts in the middle of the process.

[davidrapan]

Yes, too many requests in really short time and the logger will stop responding for a moment...

[brainstormi]

A little update just in case it's useful for somebody. Vendor obviously didn't reply me, but I found in Internet some images (no text format, sorry) about reg addresses for INVT IMars models like this one. I tried to check some of these regs with pysolarmanv5 and my Inverter randomly, and seems to work for the few that I tried and could make sense to me. I attached here for documentation purposes:

[brainstormi]

Not sure if the values collected with this adress mapping would be totally correct. For example for LCD language I get and 'I' from Italian although it's configure in Spanish in my device and IP address gateway appears as empty... hitting again a wall.

[davidrapan]

I would start with voltage, current and power values as those containing info don't have to be that straight forward. 😉

[brainstormi]

Those values are properly defined and working in the doc attached in my previos post:
voltage -> U phase voltage (0x1698)
current -> U phase current (0x1699)
power -> Input Power (0x16A2... 2 regs, only 0x16A3 populated)
Output Power (0x16A4... 2 regs, only 0x16A5 populated)

[davidrapan]

It's not about which reg are populated when it uses 2 but which are higher and lower bytes. 😉 Those "unpopulated" are higher bytes and will be used w/ number > 32767.
