The OpenEVSE Superior Sequence 48-amp EV charger made it into our Home EV Charger Buying Guide For 2020, so we figured it was solely honest that we provide one in every of our “Final Opinions” on the unit. Our Final Evaluation collection is a deep dive into the EVSE, we do not simply plug it in and declare it a sensible choice, we truly try it out and use a points-based ranking system we name the ChargerRater.

The OpenEVSE Advances collection is available in each 40-amp ($499.00) and 48-amp ($549.00) variations and is a WiFi-connected good charger. The person can regulate the facility supply from 6-amps as much as 40 or 48-amps, relying on which unit they’ve. 

It comes commonplace with a 24-ft cable, which is among the longer cables accessible on a charger right this moment. Its see-through plastic casing is NEMA-4 rated for excessive climate situations and it is the smallest, lightest 48-amp charger that we have ever examined.  

The cable did not fare too properly in our cable deep-freeze check, however as a result of it’s so skinny, it was manageable. It wasn’t the worst performing cable within the deep freeze check that we have seen, nevertheless it was removed from the very best.

Maybe the OpenEVSE’s greatest flaw could also be that it isn’t safety-certified. Whereas OpenEVSE factors out that “All security options required by SAE J1772, UL, and NEC are commonplace”, many consumers could also be involved that it hasn’t been completely examined and licensed by the UL, ETL, CE, or CSA.

The truth that OpenEVSE did not spend the tens of 1000’s of {dollars} to have the unit security licensed, might be partially why the value is as little as it’s. The 40-amp OpenEVSE is simply $499, and also you simply cannot get a 40-amp EVSE with good charging options for lower than that. It is an excellent worth if the shortage of a UL stamp is not a dealbreaker for you. 

The OpenEVSE 48 comes with a plug that can plug into both a 30-amp NEMA 14-30, a 50-amp NEMA 14-50, or a 60-amp NEMA 14-60 outlet. That is achieved by eradicating the impartial pin within the plug, as it isn’t used within the EVSE. You then set the facility supply in an internet portal to match the circuit the outlet is on. 

It is the one EVSE accessible right this moment that is ready to plug right into a NEMA 14-60 outlet and ship 48-amps to the car. All different 48-amp EVSE must be hardwired, or the proprietor must connect a NEMA 14-60 plug to the unit first.
