Hi Greg
How about this midnite box
Personally what I don’t like about single switch A or B is there is an off time.
With the midnite box, you switch both on, and turn the off the one you want. That way there is never an off time.
Just a thought.

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,
