Dude
I'm no expert on these things but here
is what i have learned about
PLUG IN GRID TIE INVERTERS here just
lately, as far as i can determine in the U.S.A.
they are not illegal to sell but when
you plug it in to your household wiring
thats when things get dicey with the
power co. your insurance company and
with the lineman who gets electrocuted
with one of these cheap devices, their
sopposed to be UL approved and IEEE 1547
and there are none i know of in the U.S.
OK4U was one and SWEA is another, neither
is approved and both come out of the
Netherlands, I guess it's ok to kill
folks over there with cheap crap.
you might not like it but save your money
buy the correct inverter have it installed
by a knowlageable professional, a little
money is not a fair trade for an injury
or maybe even a life.
