Because of safety issues (and being sued) I'm wondering if a GTI chipset
might be running self-testing during operation, to insure that a single
point logic level failure isn't keeping the unit running, when it should have shut down.?.
It might be harder to trick the GTI with a jumper wire, than you think..
But, if it's really just a standard Inverter with a GTI controller added on,
there might even be a factory test jumper to check the inverter without
the grid wired in.
Are their any schematics on-line? Or do they keep them locked up?
