Yes. the Advanced series will take whatever voltage you provide to it from 90 up to 264. 120v, 208v and 240v all work great.

Hi,
I just bought an Advanced OpenEVSE kit.
Am going to make the unit portable with a 14-50 plug.
For a 14-50 connector to 5-15 plug, exactly how is an adapter cable wired?
Thanks and good health, Weogo
NEMA 14- 50 Ground to NEMA 5-15 Ground
NEMA 14-50 Hot 1 to NEMA 5-15 Hot 1
NEMA 14-50 Hot 2 to NEMA 5-15 Neutral
NEMA 14-50 Neutral NOT CONNECTED.
Thanks!
That's what I figured, just wanted to make sure.
Good health, Weogo
If you're feeling more wealthy than handy, it looks like you can buy these: http://www.corddepot.com/shop/electric-vehicle-power/conntek-ev14400t-5-15p-to-14-50r-ev-adapter/
Hi Tony,
That's a nice looking assembly.
I do live audio production and build a lot of cabling.
The reason I originally asked the question is one video showed
tying the ground and neutral wires, which I understood to be a no go.
I've searched but can't find the video to post a correction.
Thanks and good health, Weogo
@OpenEVSE Support, thanks for the 14-50 to 5-15 wiring info. I am in a similar situation. I plan to use 220V at home for faster charging, but there is only 110V at work. Can I simply solder one 14-50 cable and one 5-15 cable at the input end of the openEVSE charger? Will the openEVSE charger auto detect the input voltage? Thanks a lot.
Hi George,
Please clarify, are you talking about having a 'Y' cable, with one leg having a 120V plug, and the other a 240V plug?
This would not pass code, as you would have a live connector exposed.
I suggest putting a 14-50 on the end of the cord.
Then make a short adapter cord with a 14-50 receptacle going to a 5-15 plug.
Additionally, a solid screw connection can be more durable than soldered.
Soldering can create a stress point where the wire can break.
Most aircraft wire connections are high quality crimps or other mechanical fasteners.
Yes, OpenEVSE will auto-detect the input voltage.
Thanks and good health, Weogo
Yes, I was thinking about a 'Y' cable. Thank you for the explanation. I will make an adapter cord then.
Can anyone help me...I bought this one and my new openevse is not working.

Any ideas?
@Aaron
The RV adapters will not work they are wired differently than EV adapters.

Hi, I know this is an old topic that I'm bumping, but it's a top result in search engines, including on the help forums here.
Is it still true that the Advanced series supports 120v operation?
The stations page specifically calls out that level 1 charging isn't supported, but I can't find any info on the switch being made. is it specifically a plug issue where an (ev specific) adapter can be used still, or was this a hardware revision?
If the former, may I suggest an edit to the https://openevse.com/stations.html page to maybe note "(adaptor required)" or even "unsupported" (given that there's plenty of people who would take that as a green light to try to pull 48A from a 15A socket...)
If the latter, can the first response on here be edited to reflect this change so there's not conflicting info as the first 2 results on search engines?
The current 2024 48A Advanced kit includes a Packard C240C contactor with a 208-240v coil. It will not activate at 120v. So, that makes the kit Level 2 only.
The for Level 1 only operation the contactor can be replaced with a Packard C240B with a 120v coil.
For Both Level 1 and Level 2 operation the contactor would need to be replaced with a 12v relay such as the Struthers Dunn relay. It actuates from 12v DC power from the AC/DC power supply.

I think I know the answer to this, but I wanted to double check before ordering.
Will I be able to use this kit with a regular 110v nema 5-15 household outlet for the time being until I get 220v installed in my garage later this year or next year? I'd like to buy one charger now and upgrade it to fit my needs.
Sorry if this is a newb question. I have some wiring experience from building guitar amps and various automotive projects, but no experience with circuits like these.
Thanks.
