[RE-wrenches] High Voltage MPPT units

[Larry Crutcher, Starlight Solar Power Systems]

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.
