ELECTRICAL INSTALLATION
Parallel Connection
•
The solar modules may be combined in
parallel to produce the desired current
output.
•
When modules are combined in parallel,
the total current is equal to the sum of
currents from each module.
•
The voltage of each module connected in
parallel should be same.
•
When connecting plural strings of modu-
les in parallel every series string or solar
module must be fused prior to combining
with other strings.
•
Bypass diodes are factory installed in the
solar modules.
•
Please refer to the applicable regional and
local codes for additional fusing require-
ments and limitations on the maximum
number of solar modules in parallel.
•
Maximum parallel strings without proper
measures, e.g. fuse 20 A and/or blocking
diode: 1 string
Parallel configuration is not limited if
proper measures are taken to block the
reverse current flow, e.g. fuses for the pro-
tection of the module and cables from
overcurrent and/or blocking diodes for
prevention of unbalanced string voltage.
Series Connection
•
The solar modules may be wired in series
to produce the desired voltage output.
•
The current of each module connected in
series should be same.
•
Do not exceed 80% of maximum system
voltage.
•
The maximum number of series connec-
ted modules can be determined by basis
on max. system voltage, the 125 % safety
factor, and the module Voc which can be
checked in the related data sheet.
•
