PV mode not working

[snkbrz]

Hello, my gridtie works in PV mode up to 1200W, but here I can't make it work in any way, if I choose any of the PV modes it resets the inverter's output power, and in battery mode it is limited to 900W. I made an adaptation and improved the cooling of the device, I would like it to work at its maximum power. Thanks in advance for your help.

Which Soyosource model do you own? A display version or the Wi-Fi dongle version? How do you try to change the operation mode? Could you describe your setup in more detail?

Any news? Can this issue be closed?

Hello. I'm sorry for the delay. Soyosource version 1200W - 110V, without display and with wifi dongle from the manufacturer installed on the esphome with its code and an RS485 module connected to the inverter. I have 2 problems.

1. If you set the operation mode to PV or PV limit, the power is reset, it does not work at all, not even setting manual mode. In this case, I would like this mode so it can work at 1200W, since, as I said, I improved the cooling and I would like to take advantage of that.

2. Power demand divider when I set it to 2, the power is limited to a maximum of 500W, I have 2 working together in the same phase, but if I put the power divider to work the loads better it limits the 2 to a maximum of 500W, only reaching it again the 900W if you set the power demand divider to 1 again, I'm getting around this with an automation in homeassistant for now, but in relation to maximum power I haven't been able to succeed in any way. I will send my code below for 1 of the devices, both are the same, just changing the name and IP address.

If you attach two inverters to the same RS485 you have to increase the max_power_demand setting too:

soyosource_virtual_meter:
  - id: virtualmeter0
    soyosource_modbus_id: modbus0
    # ...
    max_power_demand: 2400
    power_demand_divider: 2
    # ...

Could you try to describe paragraph 1 in more detail? What do you mean by "the power is reset"? You are able to use the OEM WiFi dongle and/or the soyosource_display implementation to change the operation mode to "PV limit"?

If the operation mode is "PV" or "PV limit" the inverter doesn't accept power demands via RS485?

Each inverter has its dongle converted to esphome. I don't have 2 on the same RS485 and How you said, If the operation mode is "PV" or "PV limit" the inverter doesn't accept power demands via RS485.

My inverter's motherboard is purple and yesterday, reading the solved problems, I read that there is a difference, you asked someone to test a different version at the time, but I don't know if it now works in the standard version or do I have to use the one you indicated? At the time I use it, I don't know if it's still valid.

github://syssi/esphome-soyosource-gtn-virtual-meter@add-operation-mode

I no longer have the original firmware on any dongle and my version doesn't have a display. Otherwise, I'll have to stop one day to disassemble everything and find the firmware backup to return to the standard version.

I apologize for the mistakes, for using a translator

Thank you in advance

Okay. You are using this project/implementation to switch between operation modes of the inverter. There is the risk this implementation doesn't fit to your inverter/firmware version/setup. If you have the chance please try to restore the original firmware of the WiFi dongle and try to change the operation mode using the original firmware. Does the inverter behaves different this time?
