EM5000iS has inverter technology, the EM5000S uses an AVR
EM5000iS uses a permanent magnet rotating field, the EM5000S field is copper wound.
The EM5000iS can infinitely lower it's engine speed to an idle and still produce power. The EM5000S has an econo idle, but to produce 120/240 60hz VAC continuously, it must run 3600 rpm at all times.
In certain applications the fuel savings utilized by the EM5000iS will make this generator less expensive to own than even an "off brand economy" generator.
Inverter technology produces clean power for your computer, satellite dish, etc.
