Deye 50kW HV inverter - Modbus data via USR-DR302

[Eclectic-Energy]

Hello everyone,

At home I have a Deye 8kW inverter and I am pulling data through to HA using the USR-DR302 gateway.
https://www.pusr.com/products/din-rail-rs485-serial-to-ethernet-converter-usr-dr302.html
I am getting all my data successfully.
I have another site though with two 50kW HV inverters prallelled, but no matter what I do the data does not pull through.
In the logs I get:

Now Ihave the settings on the gateway the same as with the 8kW system.
I have checked the wiring with a modbus to usb converter and modbus poll, I get values.
But not through the gateway.

Can anyone suggest some help please.
