I have a 3 branch Enphase Microinverter Grid tied system. It works great. One of the branches is only 4 panels. We are on well water so I would like to convert the small branch to a non-grid tied. The reason for that is so that in the event of a power failure, we would still be able to use the 4 panel backup system to get water. I assume that I would have to take off the 4 Enphase units, but what would I need to make my plan work? My well pump is a 220 volt line. Greatly appreciate your help.

You are currently grid-tied; how often do you loose power, and for how long? What is your budget and how well does the current grid tied system meet your power demand?
Depending on your answer, here are your choices:
All of these options could work and they're roughly organized by increasing cost and complexity.
