Al:
If I understand this correctly, you are attempting something that should
not be done. Once you combine sources you can not separate them. How can
you control the feed so only half goes into each fused switch? This defies
physics and is faulty design. You have to run the feeder
Usually those portable generators have very poor wave forms, with a big
spike on the leading edge of the sine wave. Frequency regulation also
can be all over the place as it gulps gas and sputters on impurities,
etc. When they get loaded, you keep the nasty little spike, but then
the whole
I have had a concern for a long time that as PV modules have gone up in
output that there is inevitably going to be more and more clipping taking
place as theyre paired with comparatively lower output inverters. In
effect, matching, say. a 260-watt module with a micro inverter with a max
output
We have run into many problems on very remote sites with various really
nice, small newer inverter/chargers not accepting waveforms from various
newer (inverter-based) generators. For example on one particular system
Honda 1000i works fine, Honda 2000i works fine, Honda 3000i and the charger

A while back (3 years)I installed a system (bid spec) for a school that used
215W RECs and D380s on a dual axis tracker. With the ability to monitor the
array, I see constant clipping. The modules will usually produce 199Ws
regularly. A few days ago we had temps of -34F and clear skies. My
Dan,
You may be do this as well, but I frequently deal with homeowners
with inexpensive generators, I find that the Outback and Magnum
inverters are very tolerant but I do generally have to load the
generator up to where I want it bulk charging the batteries, then adjust
the generator
Jesse:
Do you have any way to compare the total harvest for the day for a given
module in a clipping scenario versus an unclipping? The question I want
to answer is: Do we improve production enough on the shoulders of the clip
to justify the loss on the peak?
Thanks,

Many versions of the Iota, Todd before them and now Power Max ( 12v and 24v are
available, not sure yet on the 48v) are adjustable or can be ordered with an
adjustment feature which will allow for higher than normal setpoints. 16v+
if you want it

There are many reasons you might want to limit AC output. Say 120%buss bar
rule or some other rebate situation where its sized on AC, not DC size. So you
can maximize your daily production without going over the peak AC limit.

I see I forgot to mention that I have 210W modules on my home that were
producing the 215W to 223W.
William,
Your question is a good one. I've wanted to study this, but haven't had a
chance. I will look into it.
