My EV is destined to be a bicycle, I'm thinking fount hub..
On the first auto-breaker, I used dual SSRs to completely disconnect the 240 from the Sanyo.
The hardware is all indoors.
But, when I wanted to install SSR control inside the #2 Sanyo system,
I saw they were only shutting off one side of the line.
Since they don't use 120 inside the unit (like my 240 laundry dryer), they don't need to use the Neutral line.
The unit is powered by two wires on terminal connections 5 & 6. The chassis ground is for safety.

Since your Enphase power sources are need to be able to feed both 240 & 120 loads in your home, the Neutral line is a big deal.
And since you have it, you will need to disconnect
Both sides of the 240 hots.
If you lived where they used only 240 loads in the house.. Maybe one side would work okay..

It seems like it would be easy to convert a 120 IODA to switch 240.
Just pull one side of the relay coil driver/timer off the line and connect it
to the Neutral. That would give the coil 120.. And it wouldn't melt..
