Installing new Xantrex RS3000

[Gregory OConnor]

Unless The RS3 has a transfer requirement I cant see a need to
supply the RS3 with any more than 20 amps of wire size to run the
chargers and 25 amps of wire size from the inverter to the inverter
run appliances and recepticals. (300w/120volts=25amps)

My 1994 with a Heart 2800 must have some 12v/120v relays that select
the inverter power path because it is not like one leg of the panel
is hot on inverted power????

I wonder if Xantrex has insight on the retrofit or a tech hotline.
If someone here has info the only sure thing would be a horror story
or what not to do. All other installs may not be totally necessary
or proven.

when I pas a hydrolic line through plys of steel, I make the hole
round and larger. Round to keep from cracking, large to keep frm
slicing the product.
