Shopping for a Home Charger

[zhackwyatt]

Does that really make any difference to the customer though? Other that maybe delivery time.

I use Amazon a lot because I get 5% back on their credit card, returns are fairly easy, and the purchase is so easy.

Presumably though Grizzl-E gets a larger piece if not bought from Amazon. But yeah, I'll probably go with Amazon for the 5% as well.

The Grizzl-E shows up on lot my feeds will have to check it out.

Question on the Grizzl-E (or level 2 chargers in general): If I installed a 240v on a 40amp circuit, can I charge the MME at 40amps, or would I need to select the 30amps? I ask because I noticed the Grizzl-E was a 'selectable' choice. If I just left it on 40amps, would the MME still get charged....without burning my house down?

Not an electrician, but I think 40A would mean 32A charging. 40A charging needs 60A circuit.

40 amp circuit - 32 Amp rated
50 amp circuit - 40 Amp rated
60 amp circuit - 48 Amp rated.
Circuit = 125% rating.

right....then would I need to make any selection on the unit itself, or could i leave it at the default 40?

Drawing 40 amps on a 40 amp circuit will trip the breaker, or should. The 125% rating is a overload and surge buffer. I would not recommend using at 40 amps. Better dial down to 30 amps and lose a couple of charge miles an hour, or go to 50 amp circuit (breaker and probably wiring).

Read the specs before you buy.
I've seen chargers named like the drof40 that charge at 32amps and some like alset40 that charge at 40amps.
**Juice box 40 is 40 amps
**Clipper creek 40 is 32 amps

This varies between EVSEs. Some can be configured to a max amperage, others rely on the car to do that.

For Grizzl-E's unit, its max charge current is 40A, so it requires a 50A circuit, or you can open up the unit and reconfigure dip switches to keep it at a lower max that's appropriate to your home's wiring.

For the mobile charger that Ford ships with the vehicle, the max amperage is 32A (requiring a 40A circuit). But they are cleverly adjusting down that maximum by detecting what type of pigtail you've connected onto it. They provide two with the unit: a 50A NEMA 14-50 pigtail which can use the full 32A charge capability, and a NEMA 5-15 pigtail which I think is going to set the limit down to about ~8A max (and 120V instead of 240V).

No matter what EVSE you use, the in car touchscreen will also allow you to configure a max current. If you do that, then the resulting max current is whichever one is lowest (between what the car is willing to take and what the EVSE is willing to provide).

Product nomenclature usually is misleading and has little to do with actual circuit and rating requirements.

my bad - typo meant 50A.

There's a dip switch inside the Grizzl-E units to set the power level (16A for a 20A breaker, 24A for a 30A breaker, 32A for a 40A breaker, 40A for a 50A breaker). If you order direct from the company, you select how you want it set and you won't have to take the back off. If ordered from Amazon, not sure. Guessing they have it set to 32A by default.

See it at the 3:20 mark here:

I just realized the Grizzl-E sounds like it was made for the Mach-E!

Perfectl-E named! ?

Couldn't help but think of this song from the movie 1776 while I was typing that...

you have to have them set it to 32A before they ship it (part of their ordering process) or set it to 32A yourself.

So the Grizzl-E needs to be set to 32Amps for a 40 Amp circuit. If you buy directly from Grizzl-E, they have an option to preset the DIP switches to the correct values.
