Hi Glen,
That model is a disconnect switch. What the system needs is a 4 pole
transfer switch, automatic or manual, to connect the PV source to the
charge controller.
Hello Gary Willit,
Yes, you've grasped my concept precisely and I agree, getting a high
voltage DC transfer switch may nix this design. Sounds like a product
for Midnite Solar to build.
We've been thinking about a 600V controller for years that would
automatically charge your batteries when the grid goes down.
We don't know if that's the best use for our limited resource of 9
engineers.
But how big is this market I wonder ??
