Dual voltage upgrade - adds 120v compatiblity to your EVSE.

  • 1450


With this upgrade the 50A 240v contactor or 30A relay pair (depending upon the EVSE) is replaced with a 80amp 250v relay that allows your EVSE to run on both 120 and 240 volts. The OpenEVSE control board will automatically detect the voltage Level (1 or 2) upon startup and show it in the upper right corner. The amperage setting for each level is retained separately in memory and is user adjustable. This creates a truly universal Charging Station when paired with one of my many adapters sold à la carte.
