<div dir="ltr"><div class="gmail_default" style="font-family:times new roman,serif;font-size:large">I think you said it well, about 5 years ago I tried to charge a car from an off-grid system. I did not record my events but the inverter had twice the power of the level two charger, yet the inverter would get hot and trip out. I was told a ferroresonant transformer may help, and it might be different with different cars. However, I was warned the ferroresonant was to stop input wave problems from arriving at the output not to prevent the output wave problems showing up on the input. The off-grid customer gave up.</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sun, Jun 7, 2020 at 6:36 AM Hilton Dier III <<a href="mailto:hiltondier@gmail.com">hiltondier@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

<p><font face="Times New Roman, Times, serif">The issue with EV
chargers is that they create a lot of reactive power. Think of
it as "slosh" in the waveform. That means that charging at 2,000
watts sloshes a lot more than 2kW through the cable, plug,
outlet, and from the inverter. If you've got a reasonably good
sinewave inverter the charger will like it fine. However, the
inverter might not like the charger if you cut things too close.
Make sure to have a lot of top end left in your inverter. Always
use a transformer based inverter. The SW series has a big chunk
of metal in it, so that's good. At 120V the Bolt will only draw
1440 watts max.<br>

<p><font face="Times New Roman, Times, serif">An aftermarket Bolt
240V charger can draw up to 32 amps. That's 7.7 kW, so too big
for an SW. Treat it more like 40 amps. The OEM 120/240 EVSE
(smart charging cord) that comes with the car can draw 8 or 12
amps at 120V or 12 at 240V. Assume that the 8 amps is really 12
and the 12 is really 15 or a bit more. I have seen 15 amp plugs
and outlets with the hot prong melting plastic around it. The
plug on the OEM EVSE is 20A rated but make sure your outlet is
as well.</font><br>
