Answer Posted / claudiu
You can calculate the max time to use a UPS with this
formula
T max = efectiv energi / average power of the energy
that min
T max = 1377 (this is a constant, it's so big because it's
calculate in seconds)* capacity of batery in volts 12V *
capacity of batery in amper's 10Ah or other valu * number
of moduls (number of bateris to use) / how mutch power you
want to consum in W
for exemple
I have 8 baterys with 12V and 10Ah and I want to standup a
computer with 300 W consum
so
1377*8*10*12/300 = 4406.4 seconds that min 4406.4/3600 =
1.2h
sorry for my english
best regards,
