UPS / Invertor Battery Backup Time =
----------------------------------
Batt Voltage X No.of (Batteries) X Ah (Single Battery) /
Total Load (Watts) = No.Hours Backup
Example :- 12v X 20(Batteries) X 200Ah (Single Battery)
/ 6000 (Watts) = No.Hours Backup
48000 / 6000 Watts = 8 Hours Backup

Hello everyone, somebody knows what is a "surplice power" ? The hole phrase is: "This rating is appropriate for a generator set paralleled with an infinite bus e.g. a national electrical supply network or grid where the generator set is run at 100% load, 24 hours a day, 365 days a year and any surplice power is exported into the grid" Thanks in advance.
