Smart plugs

Post by Nagaman »

I’m wanting to know if a programmable smart plug is suitable for granny charging.
Can they handle up to 3kw and is there a proven brand recommended ?

I use several around the house but they are definitely only good for 10amps (2400W max).

In my case, rather than doing that, I use my OpenEVSE because it is WiFi enabled and I can control it from any computer in the house and my Smartphone.

I doubt you will easily find a 3kW smart switch.

In any case, it is NOT a good idea to simply cut the power to the input of the EVSE while charging. You should suspend the charge then cut the power.

Just cutting the power risks inductive spikes in the car charger and possible damage.

Thanks Dave, I suspect I’ll be fitting a Zappi or Ohme before long in that case.

Yes, you'll save yourself trouble using a smart EVSE that has timers, WiFi and other features.

Just cutting the power rather than the EVSE or the car initiating a proper turn off might give you a hefty repair bill.
