ED:
This to reply to You and all using the MSW DC/AC inverters.
The inverters to be produced cheap have an output that is "Flip" for the positive side of the AC pulse to the "Normal HOT" ( Black wire ) of a normal electrical GRID connection, and the Negative pulse of the MSW - AC is done by "Flop" the "Normal Neutral" ( White wire ) of a normal electrical GRID connection.
FOR THIS REASON ALONE It is not a military supplied piece of equipment.
So both output lines of this "military supplied" DC/AC inverter are HOT every half cycle of the 60 HZ MSW. NOT ALLOWED BY THE MILITARY.
They are easily stackable because the only signal needed is a low level MSW - AC like (around 6 to 12 volts).
The only way to be able to use these units like a GRID equivalent AC voltage is to use a 1:1 isolation transformer, where the input is floating and connected to the DC/AC MSW inverter and the secondary output is isolated with one wire grounded ( White wire) and the other the HOT ( Black wire) -- additional expense indeed.
For the site that sells such pieces of equipments CAVEAT EMPTOR. -- and keep yourself at least 10000 leagues away from them.
INCLUDING THE PM ALTERNATORS THEY PROMULGATE.
