Thank you for posting this - there is way too little info out there.

I hope that my EV will someday have V2H. When that happens, I will want a more sophisticated EV connection. I think SolarEdge is working on this, but I don't know if there are more than 10 people who know how to hook them up to an existing SolarEdge installation.

I have a Solaredge EV charger not integrated with the Solaredge inverter. When the Solaredge EV charger is attached to the inverter, the maximum it can charge is 32 amps. However, it can charge at the full 40 amps if connected directly to the breaker. With two Teslas, that extra 8 amps decreases charging time significantly. The issue with solar boost mode, which does gets you up to 40 amps, is that you have to be home to use it; most people take their cars to work during the day and are not at home when you can use solar boost mode. If I am home on the weekend, I set my Tesla to charge at noon when my solar panels are producing and that energy is being exported, so it goes right back into my car instead of the grid. Its a good work around and let's me charge off sushine. A positive point is that the EV charger doesn't take up space on the breaker box. However, if the inverter goes down the EV charger also goes down. I can't afford for my charger to go down for any amount of time since it necessary for my cars. It's not a deal breaker, but I would like to ask you to fully inform prospective clients of these issues. One more thing. The Solaredge EV charger doesn't play well with Tesla vehicles. Periodically the Tesla does checks on itself which requires it be plugged in and have charging available (less than 1kw to run its tests). When I set the EV charger on the timer to charge at say midnight. Before midnight the Tesla reads the cut off energy from the EV charger as an error in the line and gives an error code. The error code clears later and it still charges but just it more of a nuisance to deal with error codes. So I use the Tesla to set the on/off charging times which then works perfectly. I think this just specific to Tesla though.

In addition to what you say, if there are clouds or heavy loads at home, the available solar for the car can turn on and off quite a few times. I'm not sure that is good for the car. I too charge when I'm exporting solar, and if I charge at more than the sun provides, I'll pull from the battery or the grid. I'm not sure there is a perfect way to charge. I'm in Arizona where there is lots of sun.

@@tjmozdzen No, my batteries only back up the house on a separate critical loads panel. The EV charger is connected directly to my main panel, which is also connected to the 60 amp breaker for my inverter. So if there is an extra power draw, it, pulls it from the grid and not from the batteries.

@@ushipb00 I manually charge my EV from "excess solar". I.E., plug it in when I need charge and am exporting. I work from home a lot so this helps - don't drive much. Clearly this doesn't work for someone who drives a lot and can only do this on Sat and Sunday.

@@ushipb00 If one has a Tesla solar plus battery system, I think they have a mode where the car can only charge when there is excess solar. Thinking further about this, I'm not sure that is a good idea for the intermittent power levels that would go into the car. I'm not sure exactly how that system would work because the Tesla amp charging setting is sluggish when you change the amp draw amount.

@@tjmozdzen Agreed. I think Tesla's setup is too inconsistent, and it would take longer to charge. I prefer my setup because I have the grid backing me up when I charge my EV on sunpower. There are no fluctuations in power levels.
