EG4 Chargeverter

[Zapper77]

To run this chargeveter from utility power would a 240 volt 30 amp breaker suffice?

Yes. Technically it would put the 30 amp double pole breaker at 240 watts over the 80% continuous duty rating if you charged at 100 amps non stop.

240*30 = 7200watts
56*100 = 5600watts

Not counting for safety margins, and conversion losses.. looks like it should be good.

 

[Zapper77]

240*30 = 7200watts
48*100 =

57*100/.94/240=25.26

80% continous rating is 24 amps.

Actual test results

 

[cs1234]

57*100/.94/240=25.26

80% continous rating is 24 amps.

Good thing it's configurable on amperage.

Naa run full speed.

So according to the graph... even running full speed I should never exceed 7200 watts?

Never is a strong word considering different batteries, voltage sag, etc.. It will work on the 30amp breaker, but to be within NEC spec you would need a higher amperage circuit to meet the 80% continuous maximum. Whether you feel safe running it full bore for a long time or not is up to you. The thought process is the wiring / breaker aren't meant for that kind of long term sustained heat. I would personally run it on that circuit and not worry about it.. but.. link to music video

 

[Zapper77]

I have no issue running it continuously (NEC defines continous load something like this. Max draw for 3 or more hours and something else about adding 25%) BTW the EG4 CV instructions recommend 85 amps.

 

[vriosiii]

I think I will play it safe and keep it at 85

Really the only issue when you exceed 80% is ambient heat, undersized conductors, voltage drop and nuisance tripping.

The CV only comes with a plug and the DC breaker. You would need to build/design a on and off switch based on what your BMS supports.

EG4 6500EX-48 has a 240v dry contact. You can buy 240v AC Contactor like CGele 2 Pole Air Conditioner Contactor 40 Amp 240V Coil,Condenser Contactor Compressor Contactor…

Will this one work with 120v ac on the coil drive ?

24 hrs disconnected.
Settings held.
No more concerns.
I'll be playing with it for a few days if anyone wants any more questions answered.
A few of us can confirm consistent results.

Yes i can confirm this as well that settings are retained.
sometimes i have to click enter couple of times if i doing it too fast after connecting AC, but the setting is back.

Yup,
I don't think that I was patient enough in the beginning. I was checking before it completely booted up.

Same, CV settings held for 24 hours.

What will you use to provide the 120v to the Coil? WiFi switch/outlet?

That is the tought.

Has anyone ordered one recently and was it shipped promptly and arrived not damaged, everyone happy with theirs so far, no surprises? Asking for a friend (am reconsidering my cancellation now that they've resolved their "issues").
