For all those asking “UPS” questions. Please understand that most UPS’s are designed to supply power long enough to shut down attaches devices. They are not designed to act as standby power. Using them as an alternative power source during load shedding is not ideal. The batteries they use are not designed to be run flat and recharged all the time. They will not last and also take an enormous amount of time to recharge, so anything higher than Stage 2 will probably drain more than they can charge. A pure sine small inverter generator or a low watt inverter with a proper deep cycle battery will repay itself over and over in the long run in my opinion. Above, personal opinion with some experience in killing a few 2000w UPS’s in home office.
