Very interesting video! Thank You! I have a question. Now I use line-interactive UPS PowerWalker VI 600 stl to protect my Hitachi invertor refrigerator. Looks like, everything works normal, but... I mean, could the approximate sin of UPS be harmful for invertor compressor and electronics in my refrigerator?
Clear informations with examples. Good job, thank you!
Absolutely great and informative video! Thank you so much!
Excellent demo!
Eaton, Huawei, Santak, APC and Delta series UPS are available from stock.
The best video so far... well explained
Great explanation thanks
Does line-interactive UPS waste more energy and battery than standby UPS when I don't need any kind of protection against voltage anomalies?

Why does my UPS have the same run time with a bigger battery. but another will run as long as the battery last?
How can i see when my UPS is on?
Thks
