      Hi, I love your products and non subscription based business model.  Your EV load management solution is so close to what I need, but my power source is 480VAC 3 phase 3 wire delta (pre transformer).  For this project I’ll be buying 15-30 EV chargers initially and upto 90 in phase 1.

      I have no problem using an external meter with modbus and pulse output like this:

      https://www.eastroneurope.com/products/view/smart-x96-5#

      Is there any kind of gateway I can use to get this back to your servers so we can load balance from that input?

       

      Thanks!

      BTW, I made a similar post on reddit seeking a solution and with more details on my use case.  If we can find a solution, I’ll update that post as well.

      Perhaps this 3 phase power meter that seems to support 480V L-L and outputs to zigbee could be used?

      To communicate with the vue utility connect to enable dynamic load balance?

      Please let me know.

        Hi Anthony,

        Thanks for these details. Please contact our support team directly (referencing this thread) so they can talk through the specifics you’ve mentioned in detail with you.

        Also! Our charger ONLY supports 208 / 240VAC @ 50 / 60Hz.

      Right, if I wasn’t clear: the plan is to install a large transformer between the 480VAC 3 phase delta panel  and the 240VAC 3 phase subpanel where the chargers would connect.

      Details here: https://drive.google.com/file/d/1VLjnDZLxE1yLJCqiHKGUdVRJwA3Pja2-/view

      Contacting support basically said monitoring 480V 3 phase panels may be considered someday.

      In my opinion, your devices either need a way to accept RS485 Modbus input or your datacenter could accept Modbus TCP messages from smart meters over the internet, the aforementioned Eastron meter supports this: https://www.eastrongroup.com/product/panel-board/ethernet-modbus-tcp-three-phase-panel-mounted-panel-meter-for-panel-board.html

      The source IP will be unique to each customer,  and you could support Dynu or ClouDNS for customer IP lookup for those customer unable to secure a static public IPv4 address.  This would be the easiest way to add support for monitoring higher voltage 3 phase panels that are popular in the MDU space.

      Condominiums / apartment buildings / MDUs  are the big unmet need in the EV charging space.  Please consider supporting this use case, as the unmet need/market potential is very large.  I am happy to work with you to develop such a solution as I currently have one of these Eastron X96 meters on my network and can send Modbus TCP packets your way now.
