Question 1

Question 2

How easy is it to set charge rates  - for instance I might want to charge at 2.5 kW on most days and switch to 6.6 kW on certain days.

Accepted Answer

For me, it is very quick and easy to change the rate of charge.  I have the prior version of this charger, which has the same method of charge rate adjustment. I have removed the four front screws and use spring clamps you might use in a woodshop to hold the front cover closed.  To adjust the charge rate I remove the spring clamps (3 seconds), swing the cover up (its hinged on top), grab my little screwdriver which I've left there behind the front cover, rotate the adjusting "switch" (5 seconds), set the screwdriver down, cover down, clamps on (5 seconds), done.  This is a valuable feature for our situation...I've changed the setting on the charge rate hundreds of times to suit the current need.

Question 3

Can an extension cord be used with this?  I have a 240V dryer plug in my garage, but it's located near a cabinet, so there's no wall space near it.

Accepted Answer

Yes. And this is coming from an electrician. You would need at a minimum 10 Gauge SO though given the chargers ability to draw near maximum current for extended times I would recommend 8 Gauge SO which can be difficult to find. You then would simply need a NEMA L14-30 Amp rated plug assuming your Dryer used the same socket. You should be aware though that consists of a pair of Hot conductors, a Neutral, and a Ground line while most Electric Dryers use a NEMA L14-50 which only has a Pair of Hot conductors and a Ground, NO NEUTRAL, which may make it useless for the charger as a Neutral is needed.

Question 4

Just purchased electric vehicle and i need to install 30a ev charger inside my garage. is this unit just plug into the garage electrical outlet?

Accepted Answer

Like all Level 2 EVSE units, this requires a 240V circuit.  This particular model plugs into a 6-50R receptacle, which is a fat 3-prong receptacle used in some dryers (or even some welders plug into this type of receptacle).  It needs to be installed on a dedicated 40A circuit breaker.  I was able to install the circuit breaker and wiring myself because I had easy access to my subpanel in the garage, but if you don't have easy access or aren't sure how to wire it up, definitely have a professional do it.  There is also a direct hard wire version that skips the plug and is wired directly to the circuit.We've had our Siemens EVSE since November, use it almost every day/night, works great.  Even though all EVs have some type of charge timer, I find the delay feature on this unit to be very convenient for charging the car overnight.
