As Ben described if you see a substantial voltage drop between what you see at the alternator, and what is going into the inverter that is likely your problems. If the circuit is unloaded there may be no voltage drop.
Conversely, if the voltage was high, and the inverters see voltage over some value (30 volts maybe) they will also shut down. At least my inverters will.
