Hi Becker,

Steve is right. I searched also on the SMA website and it seems your devices use 32bit values and need to be parsed the correct way with Steve's solution.

I guess that explains why when we were trying to request for a value, [in your other topic](https://discourse.nodered.org/t/query-modbus-registers-for-sma-inverter-without-crash/32788/12), with **quantity 1** you were getting an error.
