I have PDF versions of the manuals and they clearly state compliance in 
the first section under safety.  The text is below:

Regulatory ComplianceThe GT Inverter has complete on-board over-current, 
over-temperature and anti-islanding protection, and meets U.S., Canadian 
and international safety operating standards and code requirements:•UL 
1741 1st Edition – Standard for Inverters, Converters, and Controllers 
for Use in Independent Power Systems•CSA C22.2 No. 107.1-01 General Use 
Power Supplies•IEEE C62.41 Recommended Practice on Surge Voltages in 
Low-Voltage AC Power Circuits (Location Category B3).
