USR-W630 IncompleteReadError

Issue related to

Sunsynk / mbusd Home Assistant Add-On

Describe the issue/bug

I'm having trouble connecting to a sunsynk 8.8kw ECCO via a USR-W630. It doesn't even log the serial number from the inverter and every read errors with an "IncompleteReadError".

The inverter shows an ID of "01" so I've tried setting the "MODBUS_ID" to both 1 and "01" but neither seem to have any effect. I've also set READ_SENSOR_BATCH_SIZE to 8 as I've seen mentioned but that doesn't seem to help.

I've tried all 4 "Data Transfor Mode"s on the W630 and both inverter drivers in the addon.

I'm at a bit of a loss for what else to try, any help would be appreciated.
