off topic question, low-cost UPS units. msw or tsw?
I have a Kil-A-Watt meter, and have seen how the VAC reading indicates low with my msw inverter. If my UPS indicates normal VAC(while unplugged from outlet), does this mean that it it providing tsw from battery? If so, that would be a good reason to search thrift stores, $25 for a tsw backup is a sweet deal ($10 for discarded UPS, $15 for new battery).
