[RE-wrenches] Battery Backup for Older Enphase Systems

[Matt Sherald]

I'd appreciate some ideas as to what backup system designs work well with
the older Enhase equipment (M250/215 era).

I've tried this at home with a XW4024, but the frequency rise causes the
lights to flicker and it is awfully unpleasant.

A customer of mine has asked about backup to go with an array that uses
M250s and this prompted me to write.

Thanks in advance!
