CAUTION!
Installing a SolarEdge system without ensuring compatibility of the model
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 compatibility of the power optimizers’ connectors with the PV
model’ connectors to which they are connected:
Use identical connectors from the same manufacturer and of the same type
on both the power optimizers and on the models; or
Verify that the connectors are compatible in the following way:
The model connector manufacturer should explicitly verify compatibility
with the SolarEdge optimizer connector; and
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
The minimum and maximum string length guidelines are stated in 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#/.
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 optimizer inputs in parallel, use a branch cable.
Some commercial power optimizer models have a dual input.
StorEdge Single Phase Inverter with HD-Wave Technology MAN-01-00627-1.1
14 Installation Guidelines

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 conductor length:
Do not use extension cables between a module and a power optimizer,
between two modules connected to the same optimizer, or between two
optimizers other than in the cases specified below.
You can use extension cables 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, as long as the maximum distance is not exceeded.
NOTE
Use at least 11 AWG/ 4 mm² DC cables.
The total cable length of the string (excluding power optimizers’
cables) should not exceed 1000ft./300 m from DC+ to DC- of the
inverter.
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
optimizers are connected to unshaded modules, add more optimizers to the string.
To allow for heat dissipation, maintain a minimum of 2.5 cm / 1" clearance between
the power optimizer and other surfaces, on all sides except the mounting bracket
side.
Figure 2: Power optimizer clearance
When installing modules in a confined space, for example, if installing Building-
integrated photovoltaic (BIPV) modules, ventilation measures may be needed to
Chapter 2: Installing the Power Optimisers 15
StorEdge Single Phase Inverter with HD-Wave Technology MAN-01-00627-1.1

ensure the power optimizers are not be exposed to temperatures outside their
specifications.
Step 1: Mounting the Power Optimisers
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 appropriate 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 model support structure.
5. Record power optimizer serial numbers and locations, as described in Reporting and
Monitoring Installation Data on page 49.
Step 2: Connecting a PV Module to a Power Optimizer
NOTE
Images are for illustration purposes only. Refer to the label on the product to
identify the plus and minus input and output connectors.

16 Step 1: Mounting the Power Optimisers

Connect the Plus (+) output connector of the module to the Plus (+) input
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. Connect the rest of the power optimizers in the string in the same manner.
WARNING!
If using a dual-input power optimizer and some inputs are not used, seal the
unused input connectors with the supplied pair of seals.
Chapter 2: Installing the Power Optimisers 17
StorEdge Single Phase Inverter with HD-Wave Technology MAN-01-00627-1.1

Figure 4: Power optimizers connected in series
3. If you intend to monitor the installation, using the monitoring platform, record the
physical location of each power optimizer, as described in Creating Logical and
Physical Layout using Installation Information on page 50.
Step 4: Verifying Proper Power Optimiser Connection
When a model is connected to a power optimizer, the power optimizer outputs a safe
voltage of 1V (±0.1V). Therefore, the total string voltage should equal 1V times the
number of power optimizers connected in series in the string. For example, if 10 power
optimizers are connected in a string, then 10V should be produced.
Make sure the PVmodels are exposed to sunlight during this process. The power
optimizer will only turn ON if the PVmodel provides at least 2W.
In SolarEdge systems, due to the introduction of poweroptimizers between the PV
models and the inverter, the short circuit current ISC and the open circuit voltage VOC
hold different meanings from those in traditional systems.
For more information about the SolarEdge system’s string voltage and
current, refer to the VOC and ISC in SolarEdge Systems Technical Note ,
available on the SolarEdge website at:
https://www.solaredge.com/sites/default/files/isc_and_voc_in_solaredge_
sytems_technical_note.pdf
To verify proper power optimizer connection:
Measure the voltage of each string individually before connecting it to the other strings
or to the inverter. Verify correct polarity by measuring the string polarity with a
voltmeter. Use a voltmeter with at least 0.1V measurement accuracy.
NOTE
Since the inverter is not yet operating, you may measure the string voltage and
verify correct polarity on the DC wires inside the Connection Unit.
For troubleshooting power optimizer operation problems, refer to Power Optimiser
Troubleshooting on page 67.
