<p>Also have a customer with a Leaf that can charge from a dual GVFX
system. He uses the 120 vac charger. Lower charge rates are more
efficient both for the car's battery and the solar/ battery
system, so I recommend sticking to the 120 vac chargers if
possible.<br>

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>

<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>
</font></p>
<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>
