Flooded Cell
5. Battery system size (fill in what you know atleast 2 out of 3):
volts (e.g. 24, 48, 125, etc.)
amps (e.g. 100, 300, 600,etc.)
total VA (e.g. 2000, 4000, 10000, etc.)
hours of capacity at rated load (e.g. 0.25, 1, 8, etc.)
Note: For most accurate payback calculation, include the total VA capacity of
all
battery systems that are charged by this generator including under-desk UPS and rechargable batteries used by automation devices.
6. Cost to replace battery system:
Not sure(select this and we will compute using typical costs based on
industry averages and based on the battery size and type listed above)
$
7. Type of transfer switch between generator and battery system:
Open Transition (if you don't know, it is probably Open Transition)
Open with In-Phase Monitor
Closed Transition
Soft-Load (Zero Power) Transfer
