Hi,

Added possibility to change the inverter type. Added reading script for a Growatt SPH-TL3.
Also, included basic reading of battery values but definitely can be improved, following the protocol added to docs.
Let me know if this is interesting and if so, perhaps we can improve it.

Best regards,
Ricardo

Can we leave this as default?
Would probably be a good idea to add some documentation to this file so its easier for people to understand when they first set it up.

Suggested change
inverter_type = SPH-TL3
# Set to the model of inverter you are connecting to.
# Possible values: Default, SPH_TL3
inverter_type = Default
