Bugs in the VE.Direct MPPT HEX protocol spec

Hi there. I have a BlueSolar MPPT 75/15 running the current firmware. I've written a HEX protocol decoder against the rev 10 spec but have a couple of questions:


- Register 0xEDAC 'Load offset voltage' is listed as a u16, but if I send a GET I get a u8 back

- Register 0xEDDF 'Charger maximum current' is listed with a scale of 0.01, but if I send I GET then I get 150 back, which is 1.5 A and not the 15 A I expect.


Is the spec correct?
