[RE-wrenches] Any thoughts on this approach to adding battery backup to an existing grid tie system will be appreciated.

[Wayne Irwin]

Looks like standard AC coupling.

We typically just redo the whole system rather than retro fit. Depending on the system size, it's usually not that much more work (racking is already up) and the end result is always a regulated charge to the batteries.


It would be great if someone would come up with a regulated AC coupled charge versus an all or nothing approach via phase shifting or relay controlled.
