<div class="moz-cite-prefix">Funny that the good old SW inverters
still have features that new inverters haven't topped: the (as
mentioned) AC current input setting, still the best gen autostart
menu, dual AC inputs, and excellent reliability. I'm currently
working on a project with an SW4024 that is 17 years old, and
still working fine. We're adding batteries, modules, MPPT
controllers, etc. but the inverter is not on the upgrade list
right now.<br>
The SW plus however does not regulate AC input current as well,
and I've had the same issues with overloading small generators as
with the Outbacks. Magnums also are hard to set, and I finally
had to give up using small (under 4 kw) generators with any of the
newer larger inverters. Small genies seem to only work well with
old SWs, or small inverters with low charger draw.<br>
Using a separate Iota charger (as some pointed out) is definitely
an option, but last time I used one, they were not UL listed or
set up to wire in a code compliant manor.<br>

Yes, that's my understanding. Outback acknowledged this to me
years ago.<br>

Could it be that the SW systems are protecting the generator
with Generator Support, and the Outback inverters are not?<br>

The Outback VFX series lacks the tight input current
regulation of the SW series, so the max AC amps in is really
just a suggestion. In many cases (and especially with these
small generators) we want to set the max amps in as high as
possible to minimize charging time and maximize C/rate. Yet a
surge load can momentarily exceed the max amps setting. <br>
<br>
I have observed that the Honda inverter/generators have a
quite sensitive AC output breaker, that will sometimes trip if
a surge load (such as a refrigerator) comes on during a charge
cycle set close to the generator's capacity. This incident was
specific to a Honda 3000i. In contrast, Yamaha's EF3000iSE
will lug when overloaded - not good for the generator, but
also not likely to trip the output breaker.<br>
<br>
This is a different issue than was being discussed, but fits
your question.<br>
