[RE-wrenches] Sync problem

[Geoff Greenfield]

William - thank you for completing my thoughts... wish we had hooked up at
the show - oh well.

I believe on the Mate there are TWO amps one can play with - AC charge as
well as another "total" AC input that includes the charger as well as the
loads.  I have still popped genny breakers using this one....

For a brighter energy future,

Sorry, incomplete sentence in original post.  Corrected below:




Friends:

In addition to ramping down the charge amps, you also need to ensure that
the loads are removed for testing.  Even with charge amp at 1, if the
loads exceed the capabilities of the generator to maintain adequate
voltage and frequency the inverter will disconnect the generator.

I discussed this very issue with Outback at the show yesterday.  The GFX
series inverter has tighter input tolerances on the AC input than a none
grid-tie model.  This is because there is only one AC input and that input
needs to comply with grid tie requirements.

Another short coming of the Outback is: if the loads exceed the source
capabilities, once the transfer occurs, the source will overload, be it to
trip a source breaker or bog down a generator.  If this were an SW or XW
inverter, the inverter would synchronize with the source and assist in
delivering power to the loads.

Hi Drake-

You may be overloading the genny (and it either pops a reset breaker or
just shows a red light that there is an internal overload, requiring you
cycle the on/off switch to reset.

To "test" I suggests ramping down the charging AC amps on the mate to 1 or
so, see if the genny charges, then step up the charger amps until the unit
cuts out.  Kinda like the Appalachian torque wrench: tighten until the SS
bolt breaks off, then back it off 1/2 turn.
