

CAUTION!
Installing a SolarEdge system without ensuring compatibility of the module
connectors with the Power Optimiser 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 Optimiser
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 Power Optimisers, 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 Power Optimiser connectors 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.

IMPORTANTSAFETYFEATURE
Modules with SolarEdge power optimisers are safe. They carry only a low safety
voltage before the inverter is turned ON. As long as the power optimisers are
not connected to the inverter or the inverter is turned OFF, each Power
Optimiser will output a safe Voltage of 1V.

Chapter 2: Installing the Power Optimisers 15
Single Phase Energy Hub Inverter MAN-01-00812-1.1

Installation Guidelines
For the minimum and maximum number of Power Optimisers in a string (string
length), see the Power Optimiser 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 Optimiser, between
two modules connected to the same Power Optimiser, or between two Power
Optimisers other than in the following cases:
Between a Power Optimiser and a module:
Extension cables of up to 1.8 m are allowed for all Power Optimisers (0.9 m for
DC+, and 0.9 m for DC -).
P-Series Power Optimisers with the 4-type suffix in their part number (Pxxx-
4xxxxxx) and the Mxxxx-Series - extension cables of up to 16 m can be installed
per Power Optimiser (8 m for DC+, and 8 m for DC-).
Between two Power Optimisers or between a Power Optimiser and the inverter:
Extension cables can be installed between Power Optimisers 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 may not exceed the
following values:
Single Phase Inverters Three Phase Inverters
All - 300 m SE17K and below - 300 m
SE17.5K and above - 700 m
For connecting homerun DCcables from Power Optimisers to the inverter, use
cables with the following cross-sections:
For MC4 connectors: 2.5-10 mm²
For DCterminal blocks inside the inverter or Connection Unit (if applicable): 2.5-
16 mm²
Frame-mounted Power Optimisers are mounted directly on the module frame,
regardless of racking system (rail-less or with rails). For installation of frame-
mounted Power Optimisers, refer to
http://www.solaredge.com/sites/default/files/installing_frame_mounted_power_
optimizers.pdf.
The Power Optimiser can be placed in any orientation.
Single Phase Energy Hub Inverter MAN-01-00812-1.1
16 Installation Guidelines

If connecting more modules than Power Optimiser inputs in parallel, use a branch
cable. Some commercial Power Optimiser models have a dual input.
Position the Power Optimiser close enough to its module so that their cables can be
connected.
Make sure to use Power Optimisers that have the required output and input
conductor length.
Completely shaded modules may cause their Power Optimisers to temporarily shut
down. This will not affect the performance of the other Power Optimisers in the
string, as long as the minimum number of unshaded Power Optimisers connected in
a string of modules is met. If under typical conditions fewer than the minimum
Power Optimisers are connected to unshaded modules, add more Power Optimisers
to the string.
To allow for heat dissipation, maintain clearance as specified below.
Figure 2: Power Optimisers clearance
When installing PV modules in a confined space such as Building-integrated
photovoltaic (BIPV) modules, ventilation measures may be required to ensure that
the Power Optimisers are not exceeding the maximum temperatures stated in their
specifications.
Chapter 2: Installing the Power Optimisers 17
Single Phase Energy Hub Inverter MAN-01-00812-1.1

Step 1: Mounting the Power Optimisers
For each of the Power Optimisers(1):
1. Determine the Power Optimiser mounting location and use the Power
Optimiser mounting brackets to attach the Power Optimiser to the
support structure . It is recommended to mount the Power Optimiser
in a location protected from direct sunlight. For frame-mounted
Power Optimisers follow the instructions supplied with the optimisers,
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 holes.
CAUTION!
Drilling vibrations may damage the Power Optimiser 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 Optimiser.
Do not drill through the Power Optimiser or through the mounting holes.
3. Attach each Power Optimiser to the rack using M6 or M8 stainless steel bolts, nuts
and washers or other mounting hardware. Apply torque of 9-10 N*m.
4. Verify that each Power Optimiser is securely attached to the module support
structure.
5. Record Power Optimiser serial numbers and locations, as described in Reporting and
Monitoring Installation Data on page 46.
Step 2: Connecting a PV module to a Power Optimiser
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.
NOTE
Images are for illustration purposes only. Refer to the label on the product to

Connect the Minus (-) output connector of the module to the Minus (-) input
connector of the Power Optimiser.
Figure 3: S-Series (left) and P-Series (right) Power Optimiser 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
optimiser datasheets. Refer to the Designer for string length verification.
1. Connect the Minus (-) output connector of the string’s first power optimiser to the
Plus (+) output connector of the string’s second power optimizer. When connecting
S-Series Power Optimisers, be sure to connect the short Minus (-) output connector
of one Power Optimiser to the long Plus (+) output connector of the next Power
Optimiser.
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 optimisers in the string in the same manner.
WARNING!
If using a dual-input power optimiser and some inputs are not used, seal the
unused input connectors with the supplied pair of seals.
