The SolarEdge Site Designer is available on the SolarEdge website at http://www.solaredge.us/groups/support/downloads, under Software Tools.
l 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.
l Do not leave the power optimizers connectors disconnected. Open connectors should be mated to each other.
l Equipment grounding tightening torques: 4-6 AWG: 45 lb-in, 8 AWG: 40 lb-in, 10-14 AWG: 35 lb-in.
NOTE
The images contained in the following sections are for illustrative purposes only and may vary
depending on product models.
Step 1: Mounting and Grounding the Power
Optimizers
For each of the power optimizers1: 1. Determine the power optimizer mounting location and use the power optimizer mounting brackets to attach the power optimizer to the support structure (See Figure 2). For frame-mounted power optimizers follow the instructions supplied with the optimizers.
2. If required, mark the mounting hole locations and drill the hole.
CAUTION!
Do not drill through the power optimizer or through the mounting holes. The drilling vibrations can
damage the power optimizer and will void the warranty.

Chapter 2: Installing the Power Optimizers
3. Attach each power optimizer to the rack using the M6 (1/4'') stainless steel bolts, nuts and washers.
Apply torque of 9.5 N*m / 7 lb*ft. For 3NA series power optimizes, SolarEdge recommends mounting the power optimizer on a rail with the smooth side facing out, so that the power optimizer body will prevent its rotation.
4. Use the following methods to ground the power optimizer1:
WARNING!
The metallic enclosure of the power optimizer must be grounded in accordance with the
requirements of the local and national codes.
L'enceinte métallique de l’optimiseur de puissance doit être mise à la terre en accord avec les
régulations locales et nationales.
l
For mounting on a grounded metal rail: Use the provided 5/16'' stainless steel grounding star washer between the railing and the flat side of the mounting bracket. The grounding washer should break through the anodize coating of the railing to ensure low resistive connection. Apply torque of 9.5 N*m / 7 lb*ft.
Figure 2: Power optimizer installation and grounding using a star washer
l
For mounting on rails with sliding nut fasteners: If the star washer cannot be used, use the SolarEdge grounding plate (purchased separately) between the railing and the flat side of the mounting bracket. Apply torque of 9.5 N*m / 7 lb*ft.
Figure 3: Power optimizer installation and grounding using a grounding plate
1For a list of racking models and their appropriate grounding method, refer to
http://www.solaredge.us/files/pdfs/grounding_se_power_optimizers.pdf.
SolarEdge-StorEdge Installation Guide MAN-01-00262-1.0
13
Step 2: Connecting a PV Module to a Power Optimizer
l
For mounting on un-grounded structures (such as a wooden structure): If the star washer or the plate cannot be used, use the SolarEdge grounding lug (purchased separately) with an equipment-grounding conductor according to the supplied instructions. The grounding terminal accepts a wire size of 6-14 AWG, and must be sized for equipment grounding per NEC 250.122 requirements. Tighten the screws connecting the power optimizer to the frame and the grounding terminal screw. Apply torque of 9.5 N*m / 7 lb*ft.
Figure 4: Power optimizer grounding terminal
5. Verify that each power optimizer is securely attached to the supporting structure or the module.
NOTE
Record power optimizer serial numbers and locations, as described in Providing Installation
Information on page 61.
Step 2: Connecting a PV Module to a Power
Optimizer
For each of the power optimizers1:
l
Connect the Plus (+) output connector of the module to the Plus (+) input connector of the power optimizer.
l
Connect the Minus (-) output connector of the module to the Minus (-) input connector of the power optimizer.

Chapter 2: Installing the Power Optimizers
NOTE
Images are for illustration purposes only. Refer to the label on the product to identify the plus and
minus input and output 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 SolarEdge Site Designer for string length verification.
NOTE
The total cable length of the string (including power optimizers’ cables) should not exceed
1000ft./300m from DC+ to DC- of the inverter. Use at least 11 AWG/ 4 mm² DC cables.
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.
Figure 6: Power optimizers connected in series
3. If you intend to monitor the installation, using the SolarEdge monitoring portal, record the physical location of each power optimizer, as described in Providing Installation Information on page 61.
WARNING!
Input and output connectors are not watertight until mated. Open connectors should be mated to
each other or plugged with appropriate watertight caps.
Les connecteurs d’entrée et sortie ne sont pas étanches jusqu'à ce qu’ils soient accouplés. Les
connecteurs doivent être accouplés ou fermés avec des terminaux étanches.
SolarEdge-StorEdge Installation Guide MAN-01-00262-1.0
15
Step 4: Verifying Proper Power Optimizer Connection
Step 4: Verifying Proper Power Optimizer
Connection
After a module is connected to a power optimizer, the power optimizer outputs a safe voltage of 1V. Therefore, the total string voltage should be equal to 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 modules are exposed to sunlight during this process; otherwise, the power optimizers may not be powered. If you use a tracker, the power optimizer will turn ON only if the tracker is tracking the sun and the module provides at least 2W.
In SolarEdge systems, due to the introduction of power optimizers between the PV modules and the inverter, the short circuit current I and the open circuit voltage V hold different meanings from SC
OC
those in traditional systems. For more information about the SolarEdge system’s string voltage and current, refer to the V and I in OC
SC
SolarEdge Systems Technical Note, available on the SolarEdge website at: http://www.solaredge.us/files/pdfs/isc_and_voc_in_solaredge_systems_technical_note.pdf
To verify proper power optimizers 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.
For troubleshooting power optimizer operation problems, refer to Power Optimizer Troubleshooting on page 88.

Opening Conduit Knockouts
This step may be performed after or before mounting the inverter.
The knockouts for AC grid, PV DC and battery DC are already open. If required, use this procedure for opening additional knockouts.
For AC connections you can use one of the following conduit openings options:
l Option 1 - Connect the AC grid and backup loads wires using the AC opening (knockout already open; no need to open an additional knockout). In this case use minimum 1" conduit for inserting all wires.
l Option 2 - Use two separate conduits: minimum 1" conduit for the AC grid connection and 3/4" conduit for the load backup connection. In this case, an additional knockout should be opened for the backed-up loads.
To open conduit knockouts:
1. Move the StorEdge Connection Unit safety switch and the inverter ON/OFF switch to OFF.
NOTE
When the StorEdge Connection Unit safety switch is OFF (for example during maintenance) it may
be locked to prevent safety hazard:
1. Move the StorEdge Connection Unit safety switch to the Lock position.

Connecting to the Battery
Connecting to the Battery
To simplify the connection process it is advised to connect the battery to the inverter before mounting the battery according to the manufacturer instructions.
Follow these guidelines: l For easy access to battery connectors, it is recommended to connect the cables to the battery and to set all the battery DIP switches to their correct positions while the battery is still on the ground. The following procedure is recommended:
a. Connect all the wires to the battery connection panel
b. Mount the battery
c. Assemble the conduit between the battery and the inverter
d. Connect to the StorEdge Connection Unit
l Measure the necessary length between the StorEdge Connection Unit and the battery for all cables. The maximum distance between the battery and the inverter is 35 ft/ 10m, when using 16AWG for battery thermal power and 24AWG for battery control.
l Tie and wrap the cables t o avoid pulling them out during mounting.
l Be sure to adhere to all safety cautions and information in the battery documentation. l The battery c onnects to the DC side of the inverter. Since the inverter DC connections are on its left side, it is recommended to position the battery t o the left of the inverter to simplify wiring.
NOTE
Per NEC requirements, if the battery is more than 5ft/ 1.5m away from the inverter, an additional
external DC switch ia required adjacent to the battery.

Step 4: Reporting and Monitoring Installation Data
NOTE
This step requires connecting one of the communication options. Refer to Setting Up
Communication to the Monitoring Portal on page 71.
The SolarEdge Monitoring System
The SolarEdge monitoring portal enables accessing SolarEdge site information, including up-to-date information viewed in a physical or logical view.The monitoring portal is described in detail in the SolarEdge Monitoring Portal User Guide, available on the SolarEdge website at http://www.solaredge.us/files/pdfs/solaredge-monitoring-portal-user-guide.pdf. The SolarEdge monitoring portal can display logical and physical layouts of the installed system, as follows:
l Logical Layout: Shows a schematic logical layout of the components in the system, such as: inverters, strings and modules, as well as their electrical connectivity. This view enables you to see which modules are connected in each string, which strings are connected to each inverter, and so on.
l Physical Layout: Shows a schematic physical layout of the components in the system, such as: inverters, strings and modules, as well as their electrical connectivity. This view enables a bird’s eye view of the actual location of a system component.
60
SolarEdge-StorEdge Installation Guide MAN-01-00262-1.0
Chapter 8: Commissioning the Installation
Using the portal, you can:
l View the latest performance of specific components.
l Find under-performing components, such as modules, by comparing their performance to that of other components of the same type.
l Pinpoint the location of alerted components using the physical layout.
l See how components are connected to each other.
l Pair power optimizers remotely.
To display a logical layout, insert the inverter serial number in the new site created in the application. When the communication between the inverter and the monitoring server is established, the logical layout is displayed.
To display a physical layout, you need to map the locations of the installed power optimizers. To generate a physical mapping, use either the Site Mapper application or a mapping template, which should be filled out using the detachable stickers (see Providing Installation Information, below).
The logical and physical mapping can be used for debugging a problem using the SolarEdge monitoring portal.
If you do not report the physical and logical mapping of the installed power optimizers to SolarEdge, the SolarEdge monitoring portal will show the logical layout indicating which power optimizers are connected to which inverter, but will not show strings or the physical location of power optimizers.
The inverter may be connected to the SolarEdge monitoring portal via LAN or via an external modem connected to the inverter's RS232 connector.

Chapter 9: System Configuration
Configuring StorEdge Application
This section describes the StorEdge applications and how to configure the system per application.
Maximize Self-consumption
In this mode, the battery is automatically charged and discharged to meet consumption needs. This application requires connection to a meter.
The battery has two states:
l OFF – the battery is in standby
l ON – the battery is controlled for maximized self-consumption
Battery OFF periods can be configured to extend battery lifetime by minimizing the number of shallow discharges (for example at nighttime or during the winter). Profile Programming (for time of use arbitrage)
In this mode, the StorEdge system operates according to a configured charge/ discharge profile. This application requires connection to a meter. This application is covered in a separate application note available at http://www.solaredge.com/files/pdfs/StorEdge_TOU_profile_programming.pdf.
This application can be used whether or not PV modules are installed at the site.
Backup Power
The produced power is stored in the battery to be used during power outages. The StorEdge inverter senses the grid voltage, and when it is down it automatically switches to Backup mode, disconnecting from the grid and supplying p ower to the backed-up loads. This application requires connection to the SolarEdge Auto-transformer and a backed-up loads panel. This application can be used in one of two ways:
l Backup-only – energy stored in the battery is discharged for backup power only
l Backup with Smart Energy Management – use some of the battery energy for backup power and the rest for MSC or TOU applications.
The Backup application can be used whether or not PV modules are installed at the site.

Creating an RS485 Bus Connection
The RS485 option enables creating a bus of connected inverters, consisting of up to 31 slave inverters and 1 master inverter. Using this option, inverters are connected to each other in a bus (chain), via their RS485 connectors. The first and last inverters in the chain must be terminated.
RS485 wiring specifications:
l Cable type: Min. 3-wire shielded twisted pair (a 4-wire cable may be used)
l Wire cross-section area: 0.2- 1 mm²/ 24-18 AWG (a CAT5 cable may be used)
l Maximum nodes: 32
l Maximum distance between first and last devices: 1 km /3300 ft. NOTE
If using a cable longer than 10 m/33 ft in areas where there is a risk of induced voltage surges by
lightning, it is recommend to use external surge protection devices. For details refer to:
http://www.solaredge.us/files/pdfs/lightning_surge_protection.pdf. If grounded metal conduit are
used for routing the communication wires, there is no need for a lightning protection device.
NOTE
If a revenue grade meter is connected to your inverter, it uses the RS485 port and therefore an
RS485 communication bus cannot be created.
The following sections describe how to physically connect the RS485 bus and how to configure the bus.
SolarEdge-StorEdge Installation Guide MAN-01-00262-1.0
75

In normal operation, the middle and bottom LEDs indicate auxiliary voltages (13V from DC/DC, 5V
and 3.3V) and should always be lit. The top LED should be lit when the inverter DC voltage is at least 200 Vdc (check when both inverter
ON/OFF switch and StorEdge Connection Unit switch are ON). You can check the status screen for the Vdc value.
If all LEDs are OFF: o Check that AC voltage exists in the inverter
o Check that the communication cable between the StorEdge Connection Unit and the digital board is properly connected.
If the top LED is ON, and middle and bottom LEDs are off - an internal failure has occurred. Contact SolarEdge support.

Problem
Possible cause and troubleshooting
Power optimizers are shaded.
Pairing failed
String voltage is 0V
If you connected the inverter to the SolarEdge monitoring portal, retry pairing
remotely (during sunlight).Make sure to leave the inverter ON/OFF switch ON
and that S_OK appears on the LCD..
Power optimizer(s) output is disconnected.
Connect all power optimizer outputs
Power optimizer(s) not connected in the string.
Connect all power optimizers
String voltage not 0V but lower
than number of optimizers
Module(s) not connected properly to power optimizer inputs (not applicable to
smart modules).
Connect the modules to the optimizer inputs
String reverse polarity.
Check string polarity using a voltmeter and correct if needed.
String voltage is higher than the
number of optimizers
WARNING!
If the measured voltage is too
high, the installation may not
have a safe low voltage.
PROCEED WITH CARE! A
deviation of ±1% per string is
reasonable.

Extra power optimizer(s) connected in the string (not applicable to smart
modules).
Check if an extra power optimizer is connected in the string. If not – proceed
to next solution.
A module is connected directly to the string, without a power optimizer (not
applicable to smart modules).
Verify that only power optimizers are connected in the string and that no
module outputs are connected without a power optimizer. If the problem
persists, proceed to the next step.
Power optimizer(s) malfunction.
o
Disconnect the wires connecting the power optimizers in the string.
o
Measure the output voltage of each power optimizer to locate the power
optimizer that does not output 1V safety voltage. If a malfunctioning power
optimizer is located, check its connections, polarity, module, and voltage.
o
Do not continue before finding the problem and replacing the
malfunctioning power optimizer. If a malfunction cannot be bypassed or
resolved, skip the malfunctioning power optimizer, thus connecting a
shorter string.
