Chapter 1: Introducing the SolarEdge Power Harvesting System
Chapter 1: Introducing the SolarEdge Power
Harvesting System
The SolarEdge power harvesting solution maximizes the power output from any type of solar Photovoltaic (PV) installation while reducing the average cost per watt. The following sections describe each of the system’s components.
SolarEdge Power Optimizer
The SolarEdge power optimizers are DC‐DC converters connected to PV modules in order to maximize power harvesting by performing independent Maximum Power Point Tracking (MPPT) at the module level.
The power optimizers regulate the string voltage at a constant level, regardless of string length and environmental conditions.
The power optimizers include a safety voltage function that automatically reduces the output of each power optimizer to 1 Vdc in the following cases:
z During fault conditions
z The power optimizers are disconnected from the inverter
z The inverter’s ON/OFF switch is turned OFF
Each power optimizer also transmits module performance data over the DC power line to the inverter.
Two types of power optimizers are available:
z Module Add‐on power optimizer – connected to one or more modules
z Smart m odules ‐ the power optimizers are embedded into a module
SolarEdge Inverter
The SolarEdge inverter efficiently converts DC power from the modules into AC power that can be fed into the main AC service of the site and from there to the grid. The inverter also receives the monitoring data from each power optimizer and transmits it to a central server (the SolarEdge monitoring portal; requires Internet connection).
Some inverters are available with an optional DC Safety Unit. The DC Safety Unit is a manually operated switch for disconnecting the DC power of a SolarEdge system.
The DC Safety Unit is located below the inverter and is connected to the inverter with AC and DC wires.
SolarEdge Monitoring Portal
The SolarEdge monitoring portal enables monitoring the technical and financial performance of one or more SolarEdge sites. It provides past and present information on the system performance both at the system and module levels.

Safety
The following notes and warnings apply when installing the power optimizers. modules:
WARNING!
When modifying an existing installation, turn OFF the inverter ON/OFF switch and the AC
circuit breaker on the main AC distribution panel.
WARNING!
Input and output connectors are not watertight until mated. Open connectors should be
mated to each other or plugged with appropriate watertight caps.
CAUTION!
This unit must be operated according to the operating specifications in this document.
CAUTION!
All PV modules must be connected to a power optimizer.
CAUTION!
Cutting the power optimizer input or output cable connector is prohibited and will void the
warranty.
CAUTION!

any, on module warranty. Drilling holes in the module frame should be done according to
the module manufacturer instructions.
12
SolarEdge-Installation Guide MAN-01-00057-3.1
Chapter 2: Installing the Power Optimizers
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. In order to ensure mechanical
compatibility of the SolarEdge optimizers and the modules to which they are connected:
z
z
Use identical connectors from the same manufacturer and of the same type on
both the power optimizers and on the modules; or
Verify that the connectors are compatible in the following way:
z
The connector manufacturer should explicitly verify compatibility with the
SolarEdge optimizer connector; and
z
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 optimizers are safe. They carry only a low safety voltage
before the inverter is turned ON. As long as the power optimizers are not connected to
the inverter or the inverter is turned OFF, each power optimizer will output a safe voltage
of 1V.
Installation Guidelines
z The steps in this chapter refer to module add‐on power optimizers. For smart modules, start from Step 3: Connecting Power Optimizers in Strings on page 15. Also refer to the documentation supplied with the smart modules.
z The power optimizer can be placed in any orientation.
z Position the power optimizer close enough to its module so that their cables can be connected.
z To allow for heat dissipation, maintain a 2.5 cm/ 1" clearance distance between the power optimizer and other surfaces.
z The minimum and maximum string length guidelines are stated in the power optimizer datasheets. z Refer to the SolarEdge Site Designer for string length verification. The SolarEdge Site Designer is available on the SolarEdge website at http://www.solaredge.com/groups/support/downloads, under Software Tools.
SolarEdge-Installation Guide MAN-01-00057-3.1
13
Step 1: Mounting the Power Optimizers
z 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.
z Do not leave the power optimizers connectors disconnected. Open connectors should be mated to each other.
NOTE
The images contained in the following sections are for illustrative purposes only and
may vary depending on product models.
Step 1: Mounting 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 . 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.
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.
4. 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 35.
1Not applicable to smart modules.

SolarEdge-Installation Guide MAN-01-00057-3.1
Chapter 2: Installing the Power Optimizers
Step 2: Connecting a PV Module to a Power
Optimizer
For each of the power optimizers1:
z Connect the Plus (+) output connector of the module to the Plus (+) input connector of the power optimizer.
z Connect the Minus (‐) output connector of the module to the Minus (‐) input connector of the power optimizer.
Figure 1: Power optimizer connectors
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.
1Not applicable to smart modules.
SolarEdge-Installation Guide MAN-01-00057-3.1
15
Step 4: Verifying Proper Power Optimizer Connection
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 2: 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 35.
WARNING!
Input and output connectors are not watertight until mated. Open connectors should be
mated to each other or plugged with appropriate watertight caps.
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.

Chapter 4: Connecting the AC and the Strings
to the Inverter
If using an inverter with a DC Safety Unit, refer to the instructions in Connecting the AC and DC Strings to the DC Safety Unit on page 103.
Refer to Technical Specifications on page 81 for specifications of inverters in different countries.
Grid Connection Guidelines
NOTE
Three phase inverters require neutral connection at all times (only grids with neutral
connection are supported).
z For installation on a delta grid without neutral, multiple single phase inverters can be used.
z For more wiring information refer to the SolarEdge Recommended AC Wiring Application Note, available on the SolarEdge website at http://www.solaredge.com/files/pdfs/application‐note‐recommended‐wiring.pdf
z When connecting multiple single phase inverters in an installation connected to a three‐phase grid, phase balancing may be required by the utility or grid operator. Phase balancing is supported in the SolarEdge inverters. For detailed information, refer to the SolarEdge Phase Balancing Connection Guide, available on the SolarEdge website at http://www.solaredge.com/files/pdfs/phase_balancing_connection_guide.pdf.
Connecting the AC Grid to the Inverter
Use a three‐wire cable for a single phase connection or a five‐wire cable for three phase connection. The maximum wire size for the input terminal blocks is 16mm².
1. Turn OFF the AC circuit breaker.
2. Open the inverter cover: Release the six Allen screws and carefully move the cover horizontally before lowering it.
CAUTION!
When removing the cover, make sure not to damage internal components. SolarEdge
will not be held responsible for any components damaged as a result of incautious cover
removal.

NOTE
If power control is enabled, it is important to respect the order of grid lines connection to
the inverter. A 120deg phase difference should be kept between L1 to L2 and between
L2 to L3 (L1-L2-L3 and not, for example L1-L3-L2).
If the grid lines are not in this order, an error is displayed on the LCD and the inverter will
not produce power.
6. Tighten the screws of each terminal with a torque of 1.2‐1.5 N*m / 0.88‐1.1 lb*ft.
7. Check that the wires are fully inserted and cannot be pulled out easily. 8. Tighten the AC cable gland with a torque of 2.8‐3.3 N*m / 2.0‐2.4 lb*ft.
9. Verify that there are no unconnected wires to the inverter and that the unused terminal screws are tightened.
Connecting the Strings to the Inverter
Connect the string to the DC input pairs. If required, connect additional strings in parallel using an external combiner box/branch cables before connecting to the inverter.
NOTE
Functional electrical earthing of DC-side negative or positive poles is prohibited because
the inverter has no transformer. Grounding (earth ground) of module frames and
mounting equipment of the PV array modules is acceptable.
NOTE
SolarEdge’s fixed input voltage architecture enables the parallel strings to be of different
lengths. Therefore, they do not need to have the same number of power optimizers, as
long as the length of each string is within the permitted range.
SolarEdge-Installation Guide MAN-01-00057-3.1
27
Selecting a Residual Current Device (RCD)
Connect the DC connectors of each string to the DC+ and DC‐ connectors according to the labels on the inverter.
Figure 15: Inverter DC Connections
Selecting a Residual Current Device (RCD)
IMPORTANT SAFETY FEATURE
All SolarEdge inverters incorporate a certified internal Residual Current Device (RCD) in order to protect against possible electrocution and fire hazard in case of a malfunction in the PV array, cables or inverter. There are 2 trip thresholds for the RCD as required for certification (DIN VDE 0126‐1‐1). The default value for electrocution protection is 30 mA, and for slow rising current is 300 mA.
If an external RCD is required by local regulations, check which type of RCD is required for the relevant electric code. SolarEdge recommends using a type‐A RCD. The recommended RCD value is 100mA or 300mA unless a lower value is required by the specific local electric codes. When required by local regulations, the use of an RCD type B is permitted.
In installations where the local electric code requires the use of a lower leakage RCD, the discharge current of capacitive parasitic leakage may trip the RCD. Use the following procedure to avoid this problem:
z Select an appropriate RCD to ensure proper operation of the installation. A 30mA RCD may still trip at 15mA (according to IEC 61008). Good quality RCDs will trip at a higher value.
z PV modules with low capacitance leakage to the frame are preferable.
For detailed information, refer to the RCD Selection for SolarEdge Inverters Application Note, available on the SolarEdge website at http://www.solaredge.com/files/pdfs/se‐application‐
rcd‐selection.pdf.

11. Verify that the following information appears on the LCD panel:
z P_OK: Appears only upon first telemetry reception from the power optimizers. Indicates connection to the power optimizers and that at least one power optimizer is sending monitoring data. If P_OK does not appear, check the power optimizer, string and DC input connections. z 000/000: Appears only upon first telemetry reception from the power optimizers. Indicates the number of power optimizers that have been paired to this inverter. At this stage, the number should be 000, since no power optimizers have been paired.
z S_OK: the connection to the SolarEdge monitoring portal is successful (should appear only if the inverter is connected to the server). If S_OK is not displayed and the inverter is connected to the server, refer to Errors and Troubleshooting on page 66.
z Vac [V]: the grid AC output voltage. Verify the correct value. 30
SolarEdge-Installation Guide MAN-01-00057-3.1
Chapter 5: Commissioning the Installation
z Vdc [V]: The DC input voltage of the longest string connected to the inverter. There should be a safety voltage of 1V for each power optimizer in the string.
NOTE
A measurement error on the inverter LCD of ±3 V is acceptable.
z Pac [w]: the AC output power (should be 0.0 since the inverter is OFF). z OFF: the inverter ON/OFF switch is in the OFF position. Step 2: Pairing Power Optimizers to the Inverter
Once all connections are made, all the power optimizers must be logically paired to their inverter. The power optimizers do not start producing power until they are paired with an inverter . This step describes how to assign each inverter to the power optimizers from which it will produce power.
Perform this step when the modules are exposed to sunlight. If the string length is changed or a power optimizer is replaced, repeat the pairing process.
1. Press and hold down the inverter LCD Light button for about 10 seconds. The following message is displayed: Keep holding button

The system startup process begins:
Since the inverter is ON, the power optimizers start producing power and the inverter starts converting AC.
NOTE
When you turn ON the inverter ON/OFF switch, the DC cables carry a high voltage
and the power optimizers no longer output a safe 1V output.
When the inverter starts converting power after the initial connection to the AC, the inverter enters Standby mode until its working voltage is reached. This mode is indicated by the flickering green inverter LED.
While the inverter is in Standby mode, it monitors the grid and verifies correct grid voltage and frequency. The following message is displayed:
Waking Up...
Remaining: 051 Sec
The countdown indicates the seconds remaining until entering the Production mode. This time is in accordance with local regulations and is typically between three to five minutes.
When countdown is complete, the inverter enters Production mode and produces power. The steadily lit green inverter LED indicates this mode.

1. Verify the following: z The green inverter LED is steadily lit.
z The ON/OFF indicator on the LCD panel reads ON.
z P_OK: XXX/YYY: There is a connection to the power optimizers and at least one power optimizer is sending monitoring data. Optimizers send telemetries in a frequency of up to 10 minutes. Initially after pairing, both XXX and YYY values show 000 and the values increase as paired power optimizers are reported.
NOTE
It may take up to 20 minutes for all power optimizers to transmit their telemetries and to
be counted on the LCD screen.
z S_OK appears, if the inverter is connected to the SolarEdge monitoring portal. z Vac [V] specifies the measured grid AC output voltage. z Vdc [v] : Specifies the DC input voltage, which should equal the sum of the output voltages of all modules (and should be within the operating range of the inverter).
z Pac [W] specifies the total AC output power produced.
2. Take note of the serial # on the inverter label using the detachable 2D barcode sticker on each device. This information is used in the SolarEdge monitoring portal to identify this inverter and is needed to open a new site in the monitoring portal.

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.com/files/pdfs/solaredge‐monitoring‐portal‐user‐guide.pdf. The SolarEdge monitoring portal can display logical and physical layouts of the installed system, as follows:
z 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.
z 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.
Using the portal, you can:
z View the latest performance of specific components.
z Find under‐performing components, such as modules, by comparing their performance to that of other components of the same type.
z Pinpoint the location of alerted components using the physical layout.
z See how components are connected to each other.
z 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.

z The inverter ON/OFF switch
z The AC circuit breaker
z The DC Safety Switch Unit
2. Open the inverter cover: Release the Allen screws and carefully move the cover horizontally before lowering it.
CAUTION!
When removing the cover, make sure not to damage internal components. SolarEdge
will not be held responsible for any components damaged as a result of incautious cover
removal.
3. Loosen the screws on the front cover of the DC Safety Unit, as shown below: Figure 38: Opening the DC Safety Unit cover
4. Remove the DC Safety Unit cover.
5. Strip 35 cm of the external cable insulation and strip 8 mm of the internal wire insulation.
Figure 39: Insulation stripping – AC
6. Open the AC cable gland and insert the cable through the gland (see Figure 37).
7. Connect the grounding wire to the equipment grounding terminal in the DC Safety Unit.

8. Insert the remaining four wires through the AC conduit to the inverter, and connect them
to the appropriate terminal blocks in the inverter according to the labels on the terminal
blocks (N, L1, L2 and L3).
Figure 40: Three Phase Inverter AC Terminals
9. Tighten the screws of each terminal with a torque of 1.2‐1.5 N*m / 0.88‐1.1 lb*ft.
10. Check that the wires are fully inserted and cannot be pulled out easily.
11. Tighten the AC cable gland with a torque of 2.8‐3.3 N*m / 2.0‐2.4 lb*ft.
12. Verify that there are no unconnected wires.
NOTE
If power control is enabled, it is important to respect the order of grid lines connection to
the inverter. A 120deg phase difference should be kept between L1 to L2 and between
L2 to L3 (L1-L2-L3 and not, for example L1-L3-L2).
If the grid lines are not in this order, an error is displayed on the LCD and the inverter will
not produce power.
Connecting the Strings to the DC Safety Unit
Up to three strings may be connected in parallel to the DC input pairs of the switch. The terminals are suitable for connection of copper conductors only.
To connect the strings to the DC Safety Unit:
1. Strip 8 mm of the DC wire insulation.
2. Insert the wires into the DC input glands in the DC Safety Unit.

Appendix E: Safe DC™
Appendix E: Safe DC™
When AC supply to the inverter is shut off (by shutting off the AC breaker at the site), or when the inverter ON/OFF switch is turned to OFF, the DC voltage drops to a safe voltage of 1V per optimizer.
The SolarEdge inverters are certified for compliance with the following standards as disconnection devices for PV generators, meaning that they can replace a DC disconnect:
z IEC 60947‐3:1999 + Corrigendum: 1999 + A1:2001 + Corrigendum 1:2001 + A2:2005;
z DIN EN 60947‐3
z VDE 0660‐107:2006‐03
z IEC 60364‐7‐712:2002‐05
z DIN VDE 0100‐712:2006‐06.
In compliance with these standards, the disconnection mechanism operates as follows:
1. Turn the inverter ON/OFF switch, located at the bottom of the inverter, to OFF, or disconnect the AC by shutting off the AC breaker at the site. The DC voltage displayed on the inverter LCD begins to decrease.
If the AC breaker was shut off, the LCD does not display. In this case, wait five minutes.
2. When the DC voltage reaches a safe voltage, the PV connectors at the input to the inverter can be disconnected. A galvanic separation then exists between the PV array and the inverter.
WARNING!
Under single fault conditions, the Safe DC voltage is only guaranteed when using modules of up to: z 95Voc when using the single phase inverter z 70Voc when using the three phase inverter
