Emission Compliance

This equipment has been tested and found to comply with the limits applied by the

local regulations.

These limits are designed to provide reasonable protection against harmful interference

in a residential installation. This equipment generates, uses and can radiate radio

frequency energy and, if not installed and used in accordance with the instructions,

may cause harmful interference to radio communications. However, there is no

guarantee that interference will not occur in a particular installation. If this equipment

does cause harmful interference to radio or television reception, which can be

determined by turning the equipment off and on, you are encouraged to try to correct

the interference by one or more of the following measures:

Reorient or relocate the receiving antenna.

Increase the separation between the equipment and the receiver.

Connect the equipment into an outlet on a circuit different from that to which the

receiver is connected.

Consult the dealer or an experienced radio/TV technician for help.

Changes or modifications not expressly approved by the party responsible for

compliance may void the user’s authority to operate the equipment.

HANDLING AND SAFETY INSTRUCTIONS

During installation, testing and inspection, adherence to all the handling and safety

instructions is mandatory. Failure to do so may result in injury or loss of life and

damage to the equipment.

Safety Symbols Information

The following safety symbols are used in this document. Familiarize yourself with the

symbols and their meaning before installing or operating the system.

WARNING!

Denotes a hazard. It calls attention to a procedure that, if not correctly

performed or adhered to, could result in injury or loss of life. Do not proceed

beyond a warning note until the indicated conditions are fully understood and

met.

CAUTION!

Denotes a hazard. It calls attention to a procedure that, if not correctly

performed or adhered to, could result in damage or destruction of the

product. Do not proceed beyond a caution sign until the indicated conditions

are fully understood and met.

NOTE

Denotes additional information about the current subject.

IMPORTANTSAFETYFEATURE

Denotes information about safety issues.

Disposal requirements under the Waste Electrical and Electronic Equipment (WEEE)

regulations:

NOTE

Discard this product according to local regulations or send it back to SolarEdge.

HANDLING AND SAFETY INSTRUCTIONS 6

Three Phase Inverter with SetApp Configuration PN: SEXXK-XXXXIXXXX

IMPORTANTSAFETYINSTRUCTIONS

SAVETHESEINSTRUCTIONS

WARNING!

The inverter cover must be opened only after switching the inverter ON/OFF/P

switch located at the bottom of the inverter to OFF. This disables the DC voltage

inside the inverter. Wait five minutes before opening the cover. Otherwise, there

is a risk of electric shock from energy stored in the capacitors.

WARNING!

Before operating the inverter, ensure that the inverter AC power cable and wall

outlet are grounded properly. This product must be connected to a grounded,

metal, permanent wiring system, or an equipment-grounding conductor must

be run with the circuit conductors and connected to the equipment grounding

terminal or lead on the product.

WARNING!

Opening the inverter and repairing or testing under power must be performed

only by qualified service personnel familiar with this inverter.

WARNING!

The inverter input and output circuits are isolated from the enclosure. This

system does not include an isolation transformer and should be installed with

an ungrounded PV array in accordance with the requirements of NEC Articles

690.35 and 690.43 National Electric Code, ANSI/NFPA 70, 2011 (and Canadian

Electrical Code, Part I, for installations in Canada).

Equipment grounding is the responsibility of the installer and must be

performed in accordance with all applicable Local and National Codes.

WARNING!

Do not touch the PV panels or any rail system connected when the inverter

switch is ON, unless grounded.

WARNING!

SafeDC complies with IEC60947-3 when installing the system with a worst case

SafeDC voltage (under fault conditions) < 120V.

The worst case voltage is defined as: Voc,max+ (String Length-1)*1V, where:

Voc,max = Maximum Voc (at lowest temperature) of the PV modules in the

string (for a string with multiple modules, use the max value)

String Length = number of power optimizers in the string

CAUTION!

This unit must be operated according to the technical specification datasheet

provided with the unit.

CAUTION!

HEAVY OBJECT. To avoid muscle strain or back injury, use proper lifting

techniques, and if required - a lifting aid.

NOTE

Use PV modules rated according to IEC 61730 class A.

NOTE

The symbol appears at grounding points on the SolarEdge equipment. This

symbol is also used in this manual.

NOTE

A SolarEdge inverters can be installed in sites with an alternative power source

such as a generator. SolarEdge requires installing a physical or electronic

interlock, which will signal to the inverter when the grid has been

disconnected. Interlock procurement, installation, maintenance and support

are the responsibility of the installer. Damage to the inverter due to incorrect

interlock installation or use of an interlock that is incompatible with the

SolarEdge system will render the SolarEdge warranty invalid.

For more information on connecting an alternative power source

to SolarEdge inverter, refer to

https://www.solaredge.com/sites/default/files/se-inverter-

support-of-voltage-sources.pdf.

NOTE

The following warning symbols appear on the inverter warning label:

Risk of electric shock

Risk of electric shock from energy stored in the capacitor. Do not

remove cover until 5 minutes after disconnecting all sources of

supply.

Hot surface – To reduce the risk of burns, do not touch.

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.

Figure 1: The SolarEdge power – harvesting system components

Power Optimizer

The 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.

Each power optimizer also transmits module performance data over the DC power line

to the inverter.

Inverter

The 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 monitoring platform; requires Internet connection).
