Number of
batteries
16–20, each 12 V
If the smaller value
between the numbers of
batteries,
N
, is less than
20, the battery power is
derated to
N
/20.
16–20 batteries in each of
positive and negative strings
(The total number of batteries
is 32–40.)
The rated number of batteries
in each string is 20. If the
number of batteries is less
than 20, the power is derated
to
N
/20 (
N
is the smaller
value between the numbers of
batteries in positive and
negative strings).
