Just looked up UPS's, I'll get one ordered and plug the TV into it, and might as well plug a couple other things into it as well. Should solve the problem, and cheaper than replacing the inverter.
OK, I got this UPS and it doesn't work.
AmazonBasics Standby UPS 400VA 255W Surge Protector Battery Backup, 6 Outlets
It works to keep the TV from shutting off when switching back and forth from inverter to generator, but it doesn't like the modified sine wave from the 458 inverter. The UPS stays on and charges up with the generator running, but it shuts off and sets an alarm for frequency beyond 47-63 hz when on just the inverter.
Anybody have a UPS that they know works with the Freedom 458 inverter or any other modified sine wave inverter? I can buy a new Freedom 3012 pure sine wave inverter with a 10 ms internal switching time, which should solve the problem on it's own. But, I was hoping that a $40 UPS would solve it.
