Good Luck ! I look every year and there are never any rated this high.
A few knock-off cheap ones but???
I have used the Blue Seas and one other with this app. If you are
careful about switching under big loads/EQV's it will last.
If this is an insured home, you have to disclose this or be Lawyer
fodder in a fire. Even then I would let the client buy it.
The other way around is to use 250A rated Midnite or Schneider inverter
breakers. It is clunky as you have to know what you are doing when using
it. You could easily turn both off and lose power. The 4 position Blue
Seas takes that out and is much easier to
understand.
I did the 250s a few times and it worked well, is not inexpensive, and
was legal for Home Insurance.

Wrenches, I have a customer who has a 2 strings of AGM's @ 48 VDC that
we want to split so we can charge them at decent charge rate. Adding
more PV and/or larger generator and inverter is cost prohibitive. I've
seen Blue Seas (#3002) 4 position 500 amp switches that are rated for
32VDC. Max he could possibly pull at once with his system is less than
100 amps.
I would assume the Blue Seas 3002 would work and I'd probably use it in
my garage, but I'm not comfortable recommending it to a customer. Any
suggestions on a 60 VDC rated unit that could handle say 150 amps and
4/0 cables?
Maybe I'm being too cautious since the max load would be < 6KW and the
3002 is rated for 16kW load (32 VDC /500A)? Thoughts?
Thank you,
