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,
