15 Chapter 2: Installing the Pwer Optimizers Chapter 2: Installing the Pwer Optimizers Safety The fllwing ntes and warnings apply when installing the pwer ptimizers. Sme f the fllwing may nt be applicable t smart mdules: WARNING! When mdifying an existing installatin, turn OFF the inverter ON/OFF switch, the Cnnectin Unit and the AC circuit breaker n the main AC distributin panel. CAUTION! Pwer ptimizers are IP68/NEMA6P rated. Chse a munting lcatin where ptimizers will nt be submerged in water. CAUTION! This unit must be perated accrding t the perating specificatins prvided with the unit. CAUTION! Cutting the pwer ptimizer input r utput cable cnnectr is prhibited and will vid the warranty. CAUTION! All PV mdules must be cnnected t a pwer ptimizer. CAUTION! If yu intend t munt the ptimizers directly t the mdule r mdule frame, first cnsult the mdule manufacturer fr guidance regarding the munting lcatin and the impact, if any, n mdule warranty. Drilling hles in the mdule frame shuld be dne accrding t the mdule manufacturer instructins. CAUTION! Installing a SlarEdge system withut ensuring cmpatibility f the mdule cnnectrs with the ptimizer cnnectrs may be unsafe and culd cause functinality prblems such as grund faults, resulting in inverter shut dwn. T ensure mechanical cmpatibility f the pwer ptimizers cnnectrs with the PV mdules cnnectrs t which they are cnnected: Use identical cnnectrs frm the same manufacturer and f the same type n bth the pwer ptimizers and n the mdules; r Verify that the cnnectrs are cmpatible in the fllwing way: The mdule cnnectr manufacturer shuld explicitly verify cmpatibility with the SlarEdge ptimizer cnnectr; and A third-party test reprt by ne f the listed external labs (TUV, VDE, Bureau Veritas UL, CSA, InterTek) shuld be btained, verifying the cmpatibility f the cnnectrs. IMPORTANT SAFETY FEATURE Mdules with SlarEdge pwer ptimizers are safe. They carry nly a lw safety vltage befre the inverter is turned ON. As lng as the pwer ptimizers are nt cnnected t the inverter r the inverter is turned OFF, each pwer ptimizer will utput a safe vltage f 1V. 14

16 Installatin Guidelines Frame-munted pwer ptimizers are munted directly n the mdule frame, regardless f racking system (rail-less r with rails). Fr installatin f frame-munted pwer ptimizers, refer t frame_munted_pwer_ptimizers.pdf. The steps in this chapter refer t mdule add-n pwer ptimizers. Fr smart mdules, start frm Step 3: Cnnecting Pwer Optimizers in Strings n page 17. Als refer t the dcumentatin supplied with the smart mdules. The pwer ptimizer can be placed in any rientatin. If cnnecting mre mdules than ptimizer inputs in parallel, use a branch cable. Sme cmmercial pwer ptimizer mdels have a dual input. Psitin the pwer ptimizer clse enugh t its mdule s that their cables can be cnnected. Make sure t use pwer ptimizers that have the required utput cnductr length: Minimize the use f extensins between pwer ptimizers. Chapter 2: Installing the Pwer Optimizers Yu can use extensin cables between rws and frm the end f string t the inverter. D nt use extensin cables between the mdules and the pwer ptimizers, r between tw pwer ptimizers within a string. The minimum and maximum string length guidelines are stated in the pwer ptimizer datasheets. Refer t the Designer fr string length verificatin. The Designer is available n the SlarEdge website at Cmpletely shaded mdules may cause their pwer ptimizers t temprarily shut dwn. This will nt affect the perfrmance f the ther pwer ptimizers in the string, as lng as the minimum number f unshaded pwer ptimizers cnnected in a string f mdules is met. If under typical cnditins fewer than the minimum ptimizers are cnnected t unshaded mdules, add mre ptimizers t the string. T allw fr heat dissipatin, maintain a 2.5 cm / 1" clearance distance between the pwer ptimizer and ther surfaces, n all sides except the munting bracket side. NOTE Figure 2: Pwer ptimizer clearance The images cntained herein are fr illustrative purpses nly and may vary depending n prduct mdels. 15

17 Step 1: Munting the Pwer Optimizers Step 1: Munting the Pwer Optimizers Fr each f the pwer ptimizers1: 1. Determine the pwer ptimizer munting lcatin and use the pwer ptimizer munting brackets t attach the pwer ptimizer t the supprt structure. It is recmmended t munt the pwerptimizer in a lcatin prtected frm direct sunlight. Fr frame-munted pwer ptimizers fllw the instructins supplied with the ptimizers, r refer t frame_munted_pwer_ptimizers.pdf. 2. If required, mark the munting hle lcatins and drill the hle. CAUTION! D nt drill thrugh the pwer ptimizer r thrugh the munting hles. The drilling vibratins can damage the pwer ptimizer and will vid the warranty. 3. Attach each pwer ptimizer t the rack using M6 (1/4'') stainless steel blts, nuts and washers r ther apprpriate munting hardware. Apply trque f 9.5 N*m / 7 lb*ft. 4. Verify that each pwer ptimizer is securely attached t the mdule supprt structure. 5. Recrd pwer ptimizer serial numbers and lcatins, as described in Step 4: Reprting and Mnitring Installatin Data n page 31. Step 2: Cnnecting a PV Mdule t a Pwer Optimizer NOTE Images are fr illustratin purpses nly. Refer t the label n the prduct t identify the plus and minus input and utput cnnectrs. Fr each f the pwerptimizers: Cnnect the Plus (+) utput cnnectr f the mdule t the Plus (+) input cnnectr f the pwer ptimizer. Cnnect the Minus (-) utput cnnectr f the mdule t the Minus (-) input cnnectr f the pwer ptimizer. Figure 3: Pwer ptimizer cnnectrs 1Nt applicable t smart mdules. 16

18 Chapter 2: Installing the Pwer Optimizers Step 3: Cnnecting Pwer Optimizers in Strings Yu can cnstruct parallel strings f unequal length, that is, the number f pwer ptimizers in each string des nt have t be the same. The minimum and maximum string lengths are specified in the pwer ptimizer datasheets. Refer t the Designer fr string length verificatin. NOTE Use at least 11 AWG/ 4 mm² DC cables. The ttal cnductr length f the string (excluding pwer ptimizers cnductrs; including hme runs and necessary extensins between ptimizers) shuld nt exceed the fllwing: Inverter mdel Three phase up t SE25K Three phase SE25K and abve Ttal cnductr length ( frm DC+ t DC- f the inverter) 1000 ft. /300 m 2300 ft./ 700 m 1. Cnnect the Minus (-) utput cnnectr f the string s first pwer ptimizer t the Plus (+) utput cnnectr f the string s secnd pwer ptimizer. 2. Cnnect the rest f the pwer ptimizers in the string in the same manner. WARNING! If using a dual-input pwer ptimizer and sme inputs are nt used, seal the unused input cnnectrs with the supplied pair f seals. Figure 4: Pwer ptimizers cnnected in series 3. If yu intend t mnitr the installatin, using the mnitring platfrm, recrd the physical lcatin f each pwer ptimizer, as described in Prviding Installatin Infrmatin n page

19 Step 4: Verifying Prper Pwer Optimizer Cnnectin Step 4: Verifying Prper Pwer Optimizer Cnnectin When a mdule is cnnected t a pwer ptimizer, the pwer ptimizer utputs a safe vltage f 1V (±0.1V). Therefre, the ttal string vltage shuld equal 1V times the number f pwer ptimizers cnnected in series in the string. Fr example, if 10 pwer ptimizers are cnnected in a string, then 10V shuld be prduced. Make sure the PV mdules are expsed t sunlight during this prcess. The pwer ptimizer will nly turn ON if the PV mdule prvides at least 2W. In SlarEdge systems, due t the intrductin f pwerptimizers between the PV mdules and the inverter, the shrt circuit current I SC and the pen circuit vltage V OC hld different meanings frm thse in traditinal systems. Fr mre infrmatin abut the SlarEdge system s string vltage and current, refer t the V OC and I SC in SlarEdge Systems Technical Nte, available n the SlarEdge website at: nte.pdf. T verify prper pwer ptimizer cnnectin: Measure the vltage f each string individually befre cnnecting it t the ther strings r t the inverter. Verify crrect plarity by measuring the string plarity with a vltmeter. Use a vltmeter with at least 0.1V measurement accuracy. NOTE Since the inverter is nt yet perating, yu may measure the string vltage and verify crrect plarity n the DC wires inside the Cnnectin Unit.

If required, cnnect additinal strings in parallel using an external cmbiner bx/branch cables befre cnnecting t the inverter. NOTE Functinal electrical earthing f DC-side negative r psitive ples is prhibited because the inverter has n transfrmer. Grunding (earth grund) f mdule frames and munting equipment f the PV array mdules is acceptable. NOTE SlarEdge s fixed input vltage architecture enables the parallel strings t be f different lengths. Therefre, they d nt need t have the same number f pwer ptimizers, as lng as the length f each string is within the permitted range. Cnnect the DC cnnectrs f each string t the DC+ and DC- cnnectrs. 26

28 Figure 14: Inverter DC Cnnectins Selecting a Residual Current Device (RCD) IMPORTANT SAFETY FEATURE All SlarEdge inverters incrprate a certified internal Residual Current Device (RCD) in rder t prtect against pssible electrcutin and fire hazard in case f a malfunctin in the PV array, cables r inverter. There are 2 trip threshlds fr the RCD as required fr certificatin (DIN VDE ). The default value fr electrcutin prtectin is 30 ma, and fr slw rising current is 300 ma. NOTE Fr multiple inverters, an RCD per inverter is required. Chapter 4: Cnnecting the AC and the Strings t the Inverter If an external RCD is required by lcal regulatins, check which type f RCD is required fr the relevant electric cde. Install the residual-current device (RCD) in accrdance with the applicable lcal standards and directives. SlarEdge recmmends using a type-a RCD. The recmmended RCD value is 100mA r 300mA unless a lwer value is required by the specific lcal electric cdes. Fr extended pwer three phase inverters (SE25K, SE27.6K and SE33.3K) an RCD value f 300mA shuld be used. When required by lcal regulatins, the use f an RCD type B is permitted. In installatins where the lcal electric cde requires an RCD with a lwer leakage setting, the discharge current might result in nuisance tripping f the external RCD. The fllwing steps are recmmended t avid nuisance tripping f the external RCD: Select the apprpriate RCD fr crrect peratin f the installatin: An RCD with a rating f 30 ma may actually trip at a leakage as lw as 15 ma (accrding t IEC 61008). High quality RCDs will typically trip at a value clser t their rating. Cnfigure the trip vltage f the inverter's internal RCD t a lwer value than the trip current f the external RCD. The internal RCD will trip if the current is higher than the allwed current, but because the internal inverter RCD autmatically resets when the residual currents are lw it saves the manual reset. Fr detailed infrmatin, refer t the RCD Selectin fr SlarEdge Inverters Applicatin Nte, available n the SlarEdge website at Demand Respnse Enabling Device (DRED) Accrding t the AS/NZS standard, SlarEdge inverters set t any Australia r New Zealand cuntry setting may require cnnecting an external Demand Respnse Enabling Device (DRED, prvided by the utility) t the inverter pwer reductin interface (PRI).

When pairing succeeds, the fllwing message is displayed: P a i r i n g P a i r i n g C m p l e t e d The system startup prcess begins: Since the inverter is ON, the pwer ptimizers start prducing pwer and the inverter starts cnverting AC. WARNING! When yu turn ON the inverter ON/OFF switch, the DC cables carry a high vltage and the pwer ptimizers n lnger utput a safe 1V utput. When the inverter starts cnverting pwer after the initial cnnectin t the AC, the inverter enters Wakeup mde until its wrking vltage is reached. This mde is indicated by the flickering green inverter LED. 30
