Doing that required some changes to the batteries in that they have new meta data aligned with the other machines. I also added a BA type machine in addition to the existing PR and RE types. This way it is easy to find he batteries on the network.

-- The medium voltage solar array is an assembly of low voltage arrays.

|
-- The assembly can deliver medium voltage levels and is a 10% less efficient
|
|
-- compared to 5 individual low voltage arrays due to losses in the transformer.

-- However medium voltage is supplied.

-- Solar arrays are not able to store large amounts of energy.
