Expected Result
Distances between cable ties are the
same, and no burr exists.
The inside and outside of the cabinet
are free from conductive dust or other
sundries.
Check that cables are open-circuited
using a multimeter or an insulation
resistance tester.

● 6 kVA/10 kVA: Use a multimeter to
measure the voltage between the
positive and negative battery
terminals. Voltage range: 9.6 V x
Number of batteries to 14.4 V x
Number of batteries. For example,
if 20 batteries are installed, the
voltage between the positive and
negative battery terminals should
range from 192 V (20 x 9.6 V) to
288 V (20 x 14.4 V).
● 15 kVA/20 kVA: Use a multimeter
to measure the voltages of the
positive and negative battery
strings. Voltage range: 9.6 V x
Number of batteries to 14.4 V x
Number of batteries. For example,
if both the positive and negative
battery strings contain 20 batteries,
the voltage of each battery string
should range from 192 V (20 x 9.6
V) to 288 V (20 x 14.4 V).
