[RE-wrenches] Morningstar new battery backup , more comments and opinions

[Bill Hennessy]

We've been using ac coupling with Magnum's when adding backup to a grid-tied system.
The switchover is automatic and fast. With the Magnums, there is need for a charge controller, but the installation and wiring does take more than a day (meow).
Why would anyone want a manual transfer switch for backup? If you are gone and the power fails, it would be nice to know the sump pump will continue to work, the freezer will run and the heating system will keep the pipes from freezing.

I would appreciate more opinions and comments on the new Morningstar Controller for Grid connected systems .  I developed a simple transfer switch back for this type of application back when Grid Connected systems were 48 volts . This seems like a great idea for high voltage Grid Connected System . Tom
