[RE-wrenches] generator

[Allan Sindelar]

Larry,
The single VFX3524 takes 19A plus loads from one leg, way overloading that
120V leg. Your best bet would be to add a T240 or PSX240 to balance both
legs. Then use the 30A 240V receptacle on the Genereck. The twist-loc
receptacle doesn't run through a GFI, so the tripping will go away. Plus
your VFX can overload and trip the 20A breaker when charging at the full 19A
and a surge load comes on. This would likely solve that.

Contact me off-list if you'd like a pdf copy of the off-grid gennies article
in Home Power; it will help explain a bit about wiring with the !)$%&@
bonded-chassis neutral and a few other issues.

Fellow Wrenches,

On an off the grid system we did for a client a year or two back, we  
installed an Outback VFX3524 mounted on a Midnight Solar E Panel.   
They had a manual pull Homelight generator as back up.  All worked well.
Recently the client upgraded to an electric start 8000 watt Generac  
generator.
Now every time they start the new generator, the GFI 20 amp  
receptacle on the generator pops.
There is probably a redundant neutral to ground bond that is causing  
this but I am uncertain on the best approach to remedy this condition
Any recommendations or experience on how to get the generator to  
interface with the system?

Thanks
Larry
