inverter generator match [RE-wrenches]

[Carl Emerson]

An other angle on this issue...

We have found that some Japanese gen. sets have very poor alternators, and /or
very poor voltage regulators.
Typically we avoid any capacitive discharge voltage regulators and make sure
that the gen. set has proper electronic voltage regulation.
The two reasons we have found to cause lack of sync once the speed control
issues are eliminated are:
1. Voltage spikes. these are detected by using a meter with data hold and
looking at the AC voltage. Often we find spikes up to 400 volts present, well
outside the SW voltage window.
Our fix for this is to install a small varister module to cut off voltage
spikes that will trip out the inverter.
2. Poor wave form shape from the gen. set at low load.
Our fix for this is to introduce capacitance. I trick to do this easily in the
field is to simply plug in a long AC lead into the gen. set in parallel with
the lead to the SW.

This in many cases has eliminated the need to run a load and waste valuable
power.
