for 10 computer(300w per device).
How many battery (12V / 28Ah)we need?
If we use only Internal Battery how much we have uptime for
devices?Best Regard

First fo all SURT3000XLI is not applicable for 10 computers; since
total power required 10 x 300= 3000 W
SURT3000XLI can only provide 2400W /3000 VA
You should use at leat SURT5000XLI
On the other hand, 8 hours back up ,is not practically applicable for
SURT5000XLI since we can not charge the requird batteries, due to
limited charger capability of SURT5000XLI . It is more menaingful to use
generator with minmum required back up time till genset becomes on.
The only practical solution is
SURT7500XLI + (10)SURT192XLBP , that provides 4 hrs 34 mins at 3000w
