[RE-wrenches] Battery / no-battery

William:

Like you, I'm unaware of an inverter that functions as grid 
tied/interactive, to which a battery bank can be added later to the same 
product.

My guess is that Sunny Boy(s) would be installed first, followed by 
Sunny Island(s) if battery backup is wanted later.

Same thing could be done with Schneider/Xantrex GT grid tied, followed 
later with an XW inverter/charger.

Regards,
