    The text says that you can "power derate" the Lite via the app.
    Is this a new version of the app?
    Does it need internet connectivity?

    Clarence,

    You've always been able to de-rate the amperage thru the app if it is WiFi connected.  We only sell WiFi connected JuiceBoxes on our site, now.

    The Pro 40 Lite can do 2 things, it can give live data while charging, and the ability to change the wire rating to the appropriate setting per the circuit breaker.  EX-40A circuit breaker needs to be rated to 125% of the continuous load, which is 32A,

    The Lite still needs a connection to the internet, then?.  This isn't a new utility to make minimal connection directly to the EVSE?
    There have been requests from the field to be able to manage the derating while traveling, without being required to connect to the internet.

    Yes it does.  The wire rating is in the persistent memory, so if it is set on WiFi, charged at that rate, then disconnected from WiFi--it will set it.  Otherwise a hotspot connection to change the wire rating would work.  You could then set it, start to charge, and then remove it from the hotspot and it will remember it.

     

    These days most people have more than one device, and one with phone data.  So a non-connected tablet can connect the JuiceBox with a smartphone with data and a hot spot capability.

    So, no change.
    You need an internet connection to adjust the derate.

    There is a unit listed for sale on the https://emotorwerks.com/de/ site with a 3 phase input and a type 2 charge handle.

    Hi Alexander,

    Yes.  EU uses single mains 240V, so you would just make sure it is wired as we do our 120V adapter.

    L1 to hot, L2 to neutral/common, and Ground to earth.

    https://emotorwerks.zendesk.com/hc/en-us/articles/226388407-JuiceBox-and-120V-operation- 

    We have several EU customers with J1772 inlets.

    Hi Kris,

    Did you talk about your US version? 

    If yes, will it limitted output amperage to 12A if it fills the single phase connecting? As I foudn in the page by your link: "For the single phase, US 120V operation, the output amperage is limited to 12A, or 1.4kWs".

    Or it is about "US 120V operation" only and with the single phase, EU 230V operation, it will work in full power mode?

    Thank you!

    Hi Alex,

    Good question.  The voltage sensing is L1 and L2, so when you hook up L1 only in the US with power it senses 120V and sets the limit.  When L1 has 240V on it, it senses that and limits to 40A.

    Thank you!

    Right I undesdand:

    1. I should buy your US version

    2. Make the socket at Europe (L1 to hot, L2 to neutral/common, and Ground to earth) with 240V network

    3. Plug it in and enjoy 40A (9,6kWt) with J1772?
