20 years ago, I thought I had to fix every solar problem that crossed my
path. I've since gone into a 12 step recovery program, and have
successfully stayed "solar sober" for the past decade, with only a very
occasional relapse. The Wrenches list has many a recovering
"solarholic" among its ranks. Listen to them. You just don't want the
responsibility or the call backs. My customers that I set up with all
the right equipment hardly ever have problems, but the few orphaned
systems I've inherited, have a couple of problems a year. Its not just
your sanity, its for your customers as well. If they're just playing
around with it/ weekend fun, that's one thing, but if this is Home Sweet
Home for multiple fellow Americans, they deserve better.
Sounds like a Euro spec (230 vac single phase) inverter that they
switched the frequency from 50 Hz to 60 Hz. Even if this is a good brand
over seas, its not the right voltage, its not UL listed, and you have no
tech support. (What could possibly go wrong?)
We get a couple calls a month from folks that got a 'deal on the
internet'. We don't even take them anymore even if its installing good
equipment. It's still 1/2 the money, for double the work. And one last
thing: folks that are trying to cheap out are on average going to be
less likely to appreciate and pay for your expertise.
Just curious, who sold this to them?

I just was looking at them the other day. They do make US versions.
I don’t think they are junk, Growatt is one if not the largest
inverter company in the world.

G'Day and Happy New Year's All,
Just wanted to share this with you all. A potential client purchased
a somewhat complete system off the internet and is now seeking an
installer. I know, same old story. The package came with two Growatt
SPF-5000 ES inverters with two Huawei HW-TX-5000 transformers. The
twist to the story is apparently the inverters put out 230vac on a
single leg and the transformers are required to split the 240vac into
two legs of 120. I've never come across an inverter like this. As an
off gridder the first thing I think of is the inefficiencies of the
additional transformers to do something like this when we have plenty
of manufacturers that don't require this. I'd love to hear your
thoughts on this setup and possible experiences and pitfalls to
beware of.
PS the client is kicking themselves in the butt, lol.
Gratefully,
Christopher--
