I have a small upright freezer that uses about 200 watts running, BUT pulls 700 to start. I measured both with the Kill-A-Watt meter. Neither of my inverters will start that freezer. The pure sine inverter is rated 300run/600start and the mod sine inverter is rated 600run/1000start. So I don't believe the 'ratings' anymore.
The really nasty part is the Ames inverter doesn't trip out when trying to start the freezer. The output voltage drops to 60volts under load, but the freezer doesn't start and neither the inverters' overload breaker nor fuses trip. If that was left unattended something bad would happen.
Remember that I get batteries every year, so the number of batteries will grow over time. Probably faster than they go bad.
