When you tested just the inverter without the generator running –
you stated that there was a noticeable flicker every 20 seconds –
THE GENERATOR WAS RUNNING, IT'S JUST THAT I TURNED OFF ALL THE LOADS
TO SEE IF THE PROBLEM WOULD PERSIST AND I FOUND THAT THE RAPID
CYCLING OF THE VOLTAGE AT INPUTS QUIT AND THE VOLTAGE STABILIZED AT
~121V BUT ABOUT EVERY 20 SECONDS, JUST WHEN YOU WOULD EXPECT THE AC-
IN TO GET PICKED UP BY THE INVERTER THERE WOULD BE AN AUDIBLE CLICK,
THE VOLTAGE WOULD SUDDENLY DROP TO ABOUT 110V, THEN IMMEDIATELY
RECOVER TO ~121V. AT NO TIME DID THE AC-IN GET PICKED UP.
When the generator was connected to the inverter – was the varying
AC input voltage viewed on a digital test meter or on the MATE’s
display?
I WAS MEASURING THE AC INPUT VOLTAGE WITH A FLUKE METER AT THE INPUT
CONNECTORS ON THE FX.
Is this a 120/240VAC “split phase” generator operating with only
one inverter on it? It is possible that an internal connection in
the generators windings has fried due to overloading one output leg
of the generator – its similar to a bad solder joint where the
voltage is OK until current is pulled and then it opens up. You
might try putting the inverter on the other leg to see if you see
the same issue.
THIS IS A POSSIBILITY THAT I WILL LOOK INTO. IT IS RUNNING ON ONE LEG
OF A 240V GENSET, NOT THE IDEAL SITUATION. I'LL BE PUTTING A PSX240
ON IT TO BALANCE THE OUTPUT BUT WILL FIRST CHECK TO SEE IF IT WILL
RUN OK ON THE OTHER LEG BY ITSELF.
Be sure to check the frequency of the generator when seeing issues
like this – its often the problem.
THAT'S ON THE SHORT LIST, THANKS
Thanks all who have offered suggestions, I'll check back in with
whatever I find out.
