The limit is 20MB but this is just not to overload memory and SPI. You also have to watch other factors like CPU load and all other stuff you will put it there. How are you going to connect 300 meters? I assume it is modbus and each line has a limit of 31. OK we do not limit this in LM but this is modbus specification. The reading from so many meters will be also a slow process.
