I don't take any responsibility nor liability for using this software nor for the
installation or any tips, advice, videos, etc. given by any member of this site or any related site.
Attention this plant is in the making and not yet tested.
In particular, the behavior in summer months and the interaction with the batteries has not yet been tested by me
extensively tested in practice.
