<div class="moz-cite-prefix">Larry, one other consideration:<br>
My own Ecogen appears to be able to produce well over its rating.
I have never had an amp-clamp with me when I have observed this,
but it appears to be quite able to do so. My Magnum 4024 will
charge at 114A (as measured on a TriMetric 2025) at 28V DC, or
3,200 watts after efficiency losses, while at the same time
passing through both microwave and toaster, which are both being
run directly off of the gennie as pass-through loads, as the TM's
amps in doesn't diminish significantly. Note that this is at
6,700' elevation, which would suggest about a 23% derating, or
about 4,600 watts available. I'm sorry to not be more precise - I
really should test it.<br>
<br>
But the point is that you may have more headroom than you think.
My output breaker is 50A 1P, so I assume the 240V option would be
25A 2P. You might consider increasing this to 30A if your concern
is nuisance tripping. Also, the QO breakers have a trip curve to
allow minor surges.<br>

option would be to have a separate charger (IOTA) that just runs
from the generator. No pass through loads to the generator.
<br>
4th option would be to use a larger Kohler for backup. My
experience is that even if they don't think they'll need it, they
eventually will actually use it. Large off grid systems tend to
creep ever larger.
<br>
<br>
I'd look at all the scenarios with pricing, and pros and cons.
You'll see what makes sense.

Maybe a better approach might be to use an inverter with
"Gen-support."
<br>
That is unless a system already exists that does not have this
feature.
<br>
<br>
Plan B: use the gen start signal to disable one or more of the
larger
<br>
loads.
<br>

I know this is not what you asked for, just trying inject some
different

ideas.

Subject: [RE-wrenches] Generator automatic disconnect
<br>
<br>
Wrenches,
<br>
<br>
I want to use the Ecogen 6kW generator on a large off grid
system. The
<br>
location has very few overcast or rainy days and the generator
will rarely
<br>
be needed. My concerns is nuisance tripping the generator output
breakers if
<br>
the household load exceeds 6kW. The power system control has a
feature for
<br>
reducing the AC current used to charge the batteries but does
not have a
<br>
feature for disconnecting the AC input based on input load.
<br>
<br>
Does anyone have a solution for monitoring AC load from the
generator and
<br>
disconnect it if overloaded? It must automatically reconnect
after a short
<br>
timeout.
<br>
<br>
Thank you,
<br>
Larry Crutcher
