Feeding UPS off battery and converter?
As you may all know, the electricty supply is a bit wonky in SA at the moment..
I used to get by with a trio of APC UPS'es for brownouts and brief dropouts, but now the dropouts can last an hour or more.
I have 3 big deep discharge marine 12V batteries constantly on charge from smartchargers.and 3 decent converters (12vDC to 240V AC)
My question is whether I can plug the UPSes into the converters and thus sail through blackouts without fiddling with things.
Possible? Dangerous? Silly?
Advice please
