Rich Solar/MPP Green LV2424

I have something that is probably simple...
I've got an MPP LV2424 which is actually branded as a Rich Solar. The SolarPower java crapplette will talk to it via either the built in USB or via the serial. I cannot get mpp-solar to talk to it with either serial or the USB. When I send a --getstatus or a -c QPI, -c QID I get a 0 for the output.
What am I missing? This is great work BTW!

Start by adding debug to the command and posting the response
jblance commented
also try with a -P PI18 added to the command

Thank you very much. Did I misread that the default for the mpp's was PI30? Foolish of me not to have run through the other protocols..
Aha! -PI18 was it:
mpp-solar -p /dev/hidraw0 -P PI18 --getstatus
Command: ET - Total Generated Energy query

But for completeness, here is the debug on QID with default protocol of PI30, which, clearly isn't it..

You are also using the old version, current version is 0.15.62
Note mppsolar vs mpp-solar

Aha, thank you. Running the latest from git at the moment on an rpi.
