Hi Robert; to find the right inverter you will need to evaluate your power needs. Also, the Progressive Dynamics 1000 Watt Inverter w/ Transfer Switch # PD94FR you were looking at wouldn't work since the transfer switch is only rated for 20A. For something similar you could use the Go Power Industrial Pure Sine Wave Inverter - 1,000 Watt # 34279948 or 1,500 Watt # 34279951 and then add in a transfer switch like # 34270278 separately. view full answer...
