Carl, NZ is 240 VAC right ? 240 VAC 2 wire ?<br>
<br>
I think that the problem may have to do with leg to leg voltage cross
regulation<br>
imbalance in 120/240 3 wire systems.<br>

You can get 2 SI’s but that is pricey. SMA now makes an autoformer
(finally) but it is really big and pretty expensive (hey Robin/Bob there is an
opportunity here). Too bad they don’t make a 240 Vac SI and no
longer make the old 1800 which had a 120 Vac output.</span></font><u5:p></u5:p><o:p></o:p></p>

style='font-size:11.0pt;font-family:Calibri;color:#1F497D'>To connect in a
generator you have to understand the SI’s grid input programming.
The SI has only one physical grid “input”. I say
“input” because both side of an SI are bi-directional and can be
either and input or an output depending on power flow. If you go with Case 1
The problem is that you need to set the current limit high enough for the SB so
it can grid feed. If your SB is larger than your generator you can
overload the generator when in backup mode. You also need to allow power
flow out of the grid input which you don’t want with a small
generator. It is also nice to have wider voltage and frequency limits
when operating with the generator. Fortunately there are 2 logical
inputs for the single grid input and a digital generator mode selector input
(signal level) that is used to switch between the two. Each of these
logical inputs can have different parameters, i.e. one for grid and one for
generator. You provide a feedback a signal to the digital input mode
selector to tell the SI which set of parameters to use.<u6:p></u6:p></span></font><u5:p></u5:p><o:p></o:p></p>

ways to do the mode selection ranging from a switch (light switch or toggle
switch) near the SI to select modes to an aux contact on a full auto xfer relay.

bulletproof approach use a 3 phase manual xfer switch and use the unused third
power pole to do your digital input mode switching. This is what I have
at my house. The grid feeds one side of the manual Xfer switch and I have
an SO cord on the other side to plug in to a generator for charging during a
prolonged outage. <u6:p></u6:p></span></font><u5:p></u5:p><o:p></o:p></p>

<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>
