getting Grizzl-e charger installed for my kona 2019...

... wondering if anyone has any experience with the grizzl-e charger? I believe my kona can only take 32a and the default on the charger is 40a. this should still work, right? I mean the car regulates how much amps its taking in, right?

also i read i can reduce the amps in the charger itself to 32a by using the dip switches. but what would be the benefit of this if the car regulates the amps going to the abttery? is this necessary at all?

The car decides how much it can pull, the charger just has a max it can deliver. There is a handshake when the charging starts to decide the speed.

The dip switch allow you to install the charger on a circuit with a smaller wire gauge and breaker. If the circuit has a 50 amps breaker and the appropriate wire gauge (I think it’s 6? Not an electrician), you can leave the switch at the 40 setting.

Enjoy your new charger!

OP, 735kv (great username) has the right answer. If your circuit allows, leave the charger at it's default setting of 40amps, the Kona will take care of the rest.

I have a Grizzl-e Avalanche non-smart charger and love it, it's very rugged. I had to return it for a sensitivity problem that the first generation had (they do not have that issue anymore, it still charged but I needed to reset it every other month), but everything went smoothly with the customer service. They sent me a new charger with a return label for the old one. Super easy and free.

If you install it outdoors, get the lock kit to prevent theft.

Good device at a very nice price point. I recommend it.

Yes, 6 gauge copper should be used in a 50A circuit.

We have a a grizzl-e and left it set for 40 amps. The kona pulls about 7.4kwh when charging. I test drove an Ioniq 5 and plugged it in and it pulled almost 11kwh(sorry can’t remember exact number). The car will max out below the charger max if you leave it at 40 amps, but leaving it at 40 means on cars that can take it will take advantage of it.

My opinion is leave it at 40 if your home electrical can take it.

It's an amazing charger. I got one and it charged at 7.4kw/h. The one at my work only charges st 5.4kw/h on another brand charger.

Only thing is to make sure they install a 50 amp fuse at home. All the people that I know told me their electricians installed a 40 amp fuse instead of a 50 amp because they are hard headed.

Second we have a 120 amp panel in the garage with two 50amp breakers (planning for ev number two as well)

I have one. It charges my car outdoors and frequently gets snowed and iced over. The charger itself has never given me an error. Closing the charge door on the car after snow/ice get in there is another story.

I installed a Grizzl-e in my garage for my ‘21 Kona. I liked it so much I bought another for my summer cabin (outdoor install). No issues. Leave the charger settings alone, as others have stated in their comments.

Kona Electric will only draw 7.7kW maximum from a Level 2 charger.

As you wrote, at 240 volts this is 32 amps.

A 40 amp circuit/fuse/breaker is more than sufficient, giving more than 20% headroom for a continuous load.

I had a charger installed with 50 amp breaker and wiring, set the charger up for 50 amps, but unless I get another EV with more Level 2 capacity, it'll only ever see a 32 amp load.

I have one, had it on the full 40a, but it seems like I'm an outlier in that I installed mine in December and it failed this week. The good news is the customer service has been great and is already sending me a new unit

I have the Grizzl-E Classic v2 and set the switches to the 30A(24A Draw), it get me a 5.7kwh charge rate.

Just make sure your breakers are up to snuff, made the mistake of leaving my 30+ year old breakers in place…
