Copy and paste job from what i wrote up for the Tesla forum, the e-series is great value for a LEAF if you can find a cheap type 2 to type 1 cable at just $1340+shipping.
There are 3 levels of features
e-series
single phase (240v) select-able current 10,13,16,20amps via dip switches
Not really suitable for Tesla and the Tesla genuine charger is better value for money.
LED status bar
b-series
single phase (240v) or 3 phase (415v) select-able current 10,13,16,20,25,32 amps via dip switches max. power 22kW
Power Meter via Ethernet RJ45 debug port
Remote start switch
If you want to control when your begin charging using a low voltage and current switch ie using a raspberry pi or arduino this is the way to do it safety. why? to start charging when your solar system produces above 2400W or create a coin operated EVSE etc..
Optional RFID cards up to 20 cards can be programmed.
If multiple units are installed able to change which phase J1772 cables use via dip switches for phase balancing
c-series
Same features as the b-series but with a 2nd Ethernet port for:
Home automation with UDP
This is what I can't wait to start playing with myself this allows you to dynamically adjust the available amps to the car and stop and start charging. so where i want to implement this is to integrate my solar panel inventor and increase the the kW available to the car to decrease my solar export and gird imports. This is also a must have for anyone off grid so you can avoid doing damage to your house batteries allowing you to shed car load when other activity happen in your house, heaters, washing , showers etc... (programming guide on the keba website)
Load Management for Multiple units
Paired with a M10 Load management controller this is a keba system that allows you do have more charging stations than your have capcity for and allows you to manage the load given a 130amp feed you can install 5-6 units instead of 4, and the controller will assign 25 amps to each unit to stay under 130amps if you have 5 teslas charging or 32 amps to 2 units and 3 units 20amps if it's on a first come first served basis. or lower the available amps during peak time to avoid high costs.
Open Charge Point Protocol (OCPP) Back-end server support
This is the for creating your own charging network like chargepoint it's an SOAP XML server client interface which allows unlimited RFID cards and remote monitoring of charging units. you can either code your own server or buy it as a cloud service from Bosch and other partners you can read more about OCPP on their website WELCOME TO THE OPEN CHARGE ALLIANCE |

-----------
For home charging you may be best to stick with your tesla EVSE if you don't want the advanced features, if your thinking about putting in a work place charger and please do think about it american studies have show that free workplace charging has increased EV adoption and it shows that your company is progressive and forward thinking and environmentally aware. I'm also pushing for type 2 sockets to become the defacto standard for Australia because it supports both the older EVs and the latest and greatest.
