Array disconnect wiring

A place where users can meetup with other FlexPower One users and can find support for one another. A great place for people who have not purchased the FlexPower One yet to look up information.

Array disconnect wiring

Post by raysun »

The 80 panel mounted DC breaker terminals are labeled "Load" and "Line". Does it matter which terminal is connected to the combiner box?

Some circuit breakers are not designed to be backfed, so I would connect the terminal marked "line" to the combiner box.
