The Grizzl-E, mentioned previously, is a solid unit made in Canada and can handle low temps.
ClipperCreek is also a reliable unit, I think made in the US.
The JuiceBox 40 and ChargePoint Home Flex are also popular units.
Lots of people like this Emporia Level 2 charging station. I believe it can be powered directly by solar panels. (Could be wrong about this.)

The vehicle and the EVSE talk to each other to negotiate the charging rate. Nobody talks to the wire or circuit breaker, though, so most EVSEs can be set either with DIP switches or via an app to a maximum amperage. That max needs to be set to no more than 80% of the rating of the wire and breaker because charging an EV is a continuous load. So, if you want to charge at 40A, you need to have a 50A breaker and outlet and the wire needs to be rated for 50A. If you're using a dryer outlet, it's likely rated for 30A. That means you'll need an EVSE that can limit the draw to 24A.
