

CAUTION!
Installing a SolarEdge system without ensuring compatibility of the module
connectors with the optimizer connectors may be unsafe and could cause
functionality problems such as ground faults, resulting in inverter shut down. To
ensure mechanical and electrical compatibility of the power optimizer
connectors with the PV module connectors to which they are connected:
Use identical connectors from the same manufacturer and of the same type
on the poweroptimizers, modules and the inverter DCinput; or
Verify that the connectors are compatible in the following way:
The module connector manufacturer should explicitly verify compatibility
with the SolarEdge optimizerconnectors and the Inverter DC input
connectors.
A third-party test report by one of the listed external labs (TUV, VDE,
Bureau Veritas UL, CSA, InterTek) should be obtained, verifying the
compatibility of the connectors.

Installation Guidelines
For the minimum and maximum number of power optimizers in a string (string
length), see the power optimizer datasheets. Refer to the Designer for string length
verification. The Designer is available on the SolarEdge website at:
https://www.solaredge.com/products/installer-tools/designer#/.
Do not use extension cables between a module and a power optimizer, between two
modules connected to the same power optimizer, or between two power optimizers
other than in the following cases:
Between a power optimizer and a module:
Power optimizers with the 4-type suffix in their part number (Pxxx-4xxxxxx) -
extension cables of up to 16 m can be installed per power optimizer (8 m for DC+
and 8 m for DC-).
Power optimizers manufactured starting from working week 42, 2019, as
indicated in the serial number (Example:S/N SJ5019A-xxxxxxxx - working week
50, 2019) - extension cables of up to 16 m can be installed per power optimizer (8
m for DC+ and 8 m for DC-).
Between two power optimizers or between a power optimizer and the inverter:
Extension cables can be installed between power optimizers only from row to
row, around obstacles or pathways within a row and from the end of the string
to the inverter. The total length of the extension cables must not exceed the
following values:
Single Phase Inverters Three Phase Inverters
All - 300 m / 1000 ft SE17K and below - 300 m /1000 ft
SE20K and above - 700 m / 2300 ft
For connecting homerun DCcables from power optimizers to the inverter, use
cables with the following cross-sections:
For MC4 connectors - 8-14 AWG / 2.5-10 mm²
For DCterminal blocks inside the inverter or Connection Unit - 6-14 AWG / 2.5-
16 mm²
Chapter 2: Installing the Power Optimizers 15
StorEdge Three Phase Inverter MAN-01-00648-1.3

Frame-mounted power optimizers are mounted directly on the module
frame, regardless of racking system (rail-less or with rails). For
installation of frame-mounted power optimizers, refer to
http://www.solaredge.com/sites/default/files/installing_frame_
mounted_power_optimizers.pdf.
The power optimizer can be placed in any orientation.
If connecting more modules than power optimizer inputs in parallel, use a branch
cable. Some commercial power optimizer models have a dual input.
Position the power optimizer close enough to its module so that their cables can be
connected.
Make sure to use power optimizers that have the required output and input
conductor length.
Completely shaded modules may cause their power optimizers to temporarily shut
down. This will not affect the performance of the other power optimizers in the
string, as long as the minimum number of unshaded power optimizers connected in
a string of modules is met. If under typical conditions fewer than the minimum
power optimizers are connected to unshaded modules, add more power optimizers
to the string.
To allow for heat dissipation, maintain clearance as specified below.

Chapter 2: Installing the Power Optimizers 17
StorEdge Three Phase Inverter MAN-01-00648-1.3

Step 1: Mounting the Power Optimizers
For each of the power optimizers(1):
1. Determine the power optimizer mounting location and use the power
optimizer mounting brackets to attach the power optimizer to the
support structure . It is recommended to mount the power optimizer
in a location protected from direct sunlight. For frame-mounted
power optimizers follow the instructions supplied with the optimizers,
or refer to https://www.solaredge.com/sites/default/files/installing_frame_
mounted_power_optimizers.pdf.
2. If required, mark the mounting hole locations and drill the hole.
CAUTION!
Drilling vibrations may damage the power optimizer and will void the
warranty. Use a torque wrench or an electric drill with adjustable clutch that
meets the mounting torque requirements. Do not use impact drivers for
mounting the power optimizer.
Do not drill through the power optimizer or through the mounting holes.
3. Attach each power optimizer to the rack using M6 (1/4'') stainless steel bolts, nuts
and washers or other mounting hardware. Apply torque of 9-10 N*m / 6.5-7 lb*ft.
4. Verify that each power optimizer is securely attached to the module support
structure.
5. Record power optimizer serial numbers and locations, as described in Reporting and
Monitoring Installation Data on page 56.
Step 2: Connecting a PV module to a Power Optimizer
NOTE
Improper wiring may cause electrical faults in a PV system. To avoid electrical
faults, verify proper locking of connectors and avoid cable tension and
friction. Proper planning, materials and installation reduce the risk of electric
arcs, short-circuits and ground faults in the PV system.

connector of the power optimizer.
Connect the Minus (-) output connector of the module to the Minus (-) input
connector of the power optimizer.
Figure 3: Power optimizer connectors
Step 3: Connecting Power Optimizers in Strings
You can construct parallel strings of unequal length, that is, the number
of power optimizers in each string does not have to be the same. The
minimum and maximum string lengths are specified in the power
optimizer datasheets. Refer to the Designer for string length verification.

1. Connect the Minus (-) output connector of the string’s first power optimizer to the
Plus (+) output connector of the string’s second power optimizer.
2. To minimize electromagnetic interference (EMI), make sure to minimize the distance
between the positive and negative DC cables.
For detailed instructions, see:
https://www.solaredge.com/sites/default/files/se-emi-performance-
application-note.pdf.
3. Connect the rest of the power optimizers in the string in the same
manner.
