One less piece of equipment on the wall is always a good thing but I'm looking forward to the day when it could operate as both EVSE from the panel to charge the car or as an inverter from the car to power the panel.

Sounds a bit dubious to me. If your EVSE craps out, you then have to buy a new solar inverter? Or vice versa? Also, placement of your EVSE is chosen to make it easy to plug into the car and your solar inverter placement is usually chosen to make the install easy, cheap and aesthetically pleasing. How often are those in the same place? I guess there's an edge case where it keeps someone from having to upgrade their panel, but...

Good points Davewill.

I thought solar inverters were usually on an outside wall to help with cooling. Aren't EVSEs usually inside the garage for convenience to the EV and to keep them dry?

I looked at a townhome complex that had solar pre-installed for every unit. The inverter was in the garage. But those were really small inverters as the amount of solar for the home was maybe 2.4kw in panels. So heat management for the inverter probably wasn't that much of problem given the small amount of power being handled.

I'm not an engineer so I could be quite wrong on these points.

I don’t see much benefit to this aside from saving a panel upgrade. I’m sure this thing is pricey as well offsetting some of the other EVSE install costs.

I'm not sure you couldn't accomplish the same thing by putting an EVSE and a solar inverter together on a subpanel, anyway.

All good points. I still think such a unit may work well for smaller solar arrays (less than 5-6kW?) and lower installation costs, given the EVSE and the inverter can be in one place. It has a 12 year warranty and SolarEdge is doing pretty well these days, I doubt they will be going out of business any time soon. Extended warranties are also available, and many often buy them for the inverters, the fact it also covers the EVSE is a nice bonus IMO. Not sure if all cities allow solar to be on a subpanel.
