Obviously being tied to the grid is an important piece of the equation for solar to make sense economically. However the aggravation of not being able to use the system is difficult for customers.We are in Florida where hurricanes are common and outtages are constantly considered. We are currently looking at this as an opportunity to sell them a battery backup but the additional cost can kill some projects and having a way to install systems with some kind of transfer switch would make a ton of sense.
"Until the rules change the require a full disconnect between a solar pv system and the grid to be installed by all, there will not be any grid tie inverter that works fully without the grid."
Is this because of an NEC rule?
I don't understand why there isn't a way to install a manual transfer switch that will allow the system to power back on in the event of an outtage (similar to the way a generator works). How does a battery allow this and keep utility lineman safe?
I really appreciate the input
