AC Passthrough rating of parallel XW Systems

Issue:

What is the AC passthrough rating of parallel XW inverter systems?

Environment:

Multi-unit parallel XW system

Resolution:

IMPORTANT: In a multiple unit configuration where two or more XW units are set up together, the AC transfer relay rating remains the same at 60 amps. This AC transfer relay rating does not double/triple etc to become 120/180 amps.
WARNING FIRE HAZARD
Do not power multiple loads in excess of 60 amps even in a multiple unit configuration. Failure to follow this instruction can result in death or serious injury.

Cause:

Unequal sharing of passthrough current through parallel relays

NOTE : XW+NA models will eventually have an external transfer switch option that will allow for more units in parallel and more pass-thru capability.
