MODULE SPECIFICATIONS
Module specifications are shown in
Table 1-1 and Figure 1. (Electrical
specifications, mechanical specifica-
tions, module dimensions)
1)
Rated electrical characteristics are
within the range of –5% to +10% of
the values measured at Standard
Test Conditions (STC). STC condi-
tions are; Irradiance of 1000W/m
25°C cell temperature, AM1.5 and
solar spectral irradiance per IEC
60904-3. Note: At the time of ship-
ment, Panasonic guarantees the
output level of its modules to be -0/
+10% against Rated Power in SPECI-
FICATIONS based on factory inspec-
tion at STC conditions.
2)
Under real conditions, a photovolta-
ic module may experience condi-
tions that produce more current
and/or voltage than reported at
Standard Test Conditions. There-
fore, the Isc value of modules
should be multiplied by a factor of
1.25 to determine ampacity. An
additional factor of 1.25 may be
required for sizing conductors, fus-
es, disconnects, etc. Please refer to
section 690.8 of the National Electric
Code (NEC) for guidelines. The Voc
must be factored according to the
lowest recorded ambient tempera-
ture recorded for the location
where the modules will be installed.
Please refer to section 690.7 of the
NEC for more information regarding
voltage temperature factors.
VBHN340SA17E, VBHN330SA17E,
VBHN330KA03E and
VBHN325KA03E are equipped with
a Microinverter.
Microinverters are DC-AC inverters
connected to PV modules in order
to maximize power harvesting by
performing Maximum Power Point
Tracking (MPPT) at the module
level.
MECHANICAL LOADING
The modules should be mounted at
the four (4) quarter points by the
means shown in Figure 1.
This method offers a maximum load
shown as "Mount Location and
Load Resistance" in Table 1-2 in a
static state on the module surface.

Note: This mechanical loading value
,
was tested using the mounting de-
vice specified in section "MODULE
INSTALLATION"
As UL Certified Load Ratings, this
module meets design loads as be-
low.
1)
Positive load with Long frame
mounting
・ 33 psf (0-450mm range from edge)
･ 75 psf (230-380mm range from edge)
2)
Negative load with Long frame
mounting
･ 33 psf (0-450mm range from edge)
･ 61 psf(230-380mm range from edge)
･ 75 psf (230-345mm range from edge)
3)
Positive load with Short frame
mounting
･ 33 psf (0-250mm range from edge)
4)
Negative load with Short frame
mounting
･ 33 psf (0-250mm range from edge)

STANDARDS
VBHN340SA17E, VBHN330SA17E,
VBHN330KA03E and VBHN325KA03E
comply with the requirements of UL1703
(PV module) and UL 1741 (Microinverter,
ENPHASE ENERGY, Inc., Type IQ7X-96-
ACM-US).
FIRE CLASS OF PRODUCT
The fire rating of this module is valid
only when mounted in the manner
specified in the mechanical mount-
ing instructions.
The models in this instructions are
suitable to maintain the System Fire
Class Rating A when used with a
Listed mounting system and a roof
covering that have been rated as a
Class A System when installed on a
steep slope roof and/or a low slope
roof with "Type 2" modules.
