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. Installatin Guidelines 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 15. Als refer t the dcumentatin supplied with the smart mdules. The pwer ptimizer can be placed in any rientatin. Psitin the pwer ptimizer clse enugh t its mdule s that their cables can be cnnected. T allw fr heat dissipatin, maintain a 2.5 cm/ 1" clearance distance between the pwer ptimizer and ther surfaces. The minimum and maximum string length guidelines are stated in the pwer ptimizer datasheets. Refer t the SlarEdge Site Designer fr string length verificatin. The SlarEdge Site Designer is available n the SlarEdge website at under Sftware Tls. 13

15 Step 1: Munting the Pwer Optimizers 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. D nt leave the pwer ptimizers cnnectrs discnnected. Open cnnectrs shuld be mated t each ther. NOTE The images cntained in the fllwing sectins are fr illustrative purpses nly and may vary depending n prduct mdels. Step 1: Munting the Pwer Optimizers Fr each f the pwer ptimizers 1 : 1. Determine the pwer ptimizer munting lcatin and use the pwer ptimizer munting brackets t attach the pwer ptimizer t the supprt structure. Fr frame-munted pwer ptimizers fllw the instructins supplied with the ptimizers. 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 the M6 (1/4'') stainless steel blts, nuts and washers. Apply trque f 9.5 N*m / 7 lb*ft. 4. Verify that each pwer ptimizer is securely attached t the supprting structure r the mdule. NOTE Recrd pwer ptimizer serial numbers and lcatins, as described in Prviding Installatin Infrmatin n page Nt applicable t smart mdules. 14

Cnnect the Minus (-) utput cnnectr f the mdule t the Minus (-) input cnnectr f the pwer ptimizer. NOTE Figure 1: Pwer ptimizer cnnectrs Images are fr illustratin purpses nly. Refer t the label n the prduct t identify the plus and minus input and utput cnnectrs. 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 SlarEdge Site Designer fr string length verificatin. NOTE The ttal cable length f the string (including pwer ptimizers cables) shuld nt exceed 1000ft./300m frm DC+ t DC- f the inverter. Use at least 11 AWG/ 4 mm² DC cables. 1 Nt applicable t smart mdules. 15

17 Step 4: Verifying Prper Pwer Optimizer Cnnectin 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. Figure 2: Pwer ptimizers cnnected in series 3. If yu intend t mnitr the installatin, using the SlarEdge mnitring prtal, recrd the physical lcatin f each pwer ptimizer, as described in Prviding Installatin Infrmatin n page 35. WARNING! Input and utput cnnectrs are nt watertight until mated. Open cnnectrs shuld be mated t each ther r plugged with apprpriate watertight caps. Step 4: Verifying Prper Pwer Optimizer Cnnectin After a mdule is cnnected t a pwer ptimizer, the pwer ptimizer utputs a safe vltage f 1V. Therefre, the ttal string vltage shuld be equal t 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 mdules are expsed t sunlight during this prcess; therwise, the pwer ptimizers may nt be pwered. If yu use a tracker, the pwer ptimizer will turn ON nly if the tracker is tracking the sun and the mdule prvides at least 2W. 16

A 120deg phase difference shuld be kept between L1 t L2 and between L2 t L3 (L1-L2-L3 and nt, fr example L1-L3-L2). If the grid lines are nt in this rder, an errr is displayed n the LCD and the inverter will nt prduce pwer. 6. Tighten the screws f each terminal with a trque f N*m / lb*ft. 7. Check that the wires are fully inserted and cannt be pulled ut easily. 8. Tighten the AC cable gland with a trque f N*m / lb*ft. 9. Verify that there are n uncnnected wires t the inverter and that the unused terminal screws are tightened. Cnnecting the Strings t the Inverter Cnnect the string t the DC input pairs. 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. 27

29 Selecting a Residual Current Device (RCD) Cnnect the DC cnnectrs f each string t the DC+ and DC- cnnectrs accrding t the labels n the inverter. Figure 15: 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. If an external RCD is required by lcal regulatins, check which type f RCD is required fr the relevant electric cde. 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. When required by lcal regulatins, the use f an RCD type B is permitted. In installatins where the lcal electric cde requires the use f a lwer leakage RCD, the discharge current f capacitive parasitic leakage may trip the RCD. Use the fllwing prcedure t avid this prblem: l Select an apprpriate RCD t ensure prper peratin f the installatin. A 30mA RCD may still trip at 15mA (accrding t IEC 61008). Gd quality RCDs will trip at a higher value. l PV mdules with lw capacitance leakage t the frame are preferable.

31 Step 1: Activating the System 9. Clse the inverter cver by tightening the screws with a trque f 9.0 N*m/ 6.6 lb*ft. Fr prper sealing, first tighten the crner screws and then the tw central screws. The fllwing figure illustrates recmmended rder: Figure 16: Tightening rder f the screws 10. Turn ON the DC Safety Unit (if applicable). If an additinal external DC switch is installed between the pwer ptimizers and the inverter(s) then turn it ON. A status screen similar t the fllwing appears n the LCD panel: V a c [ V ] V d c [ V ] P a c [ w ] P _ O K : / < S _ O K > O F F 11. Verify that the fllwing infrmatin appears n the LCD panel: P_OK: Appears nly upn first telemetry receptin frm the pwer ptimizers. Indicates cnnectin t the pwer ptimizers and that at least ne pwer ptimizer is sending mnitring data. If P_OK des nt appear, check the pwer ptimizer, string and DC input cnnectins. 000/000: Appears nly upn first telemetry receptin frm the pwer ptimizers. Indicates the number f pwer ptimizers that have been paired t this inverter. At this stage, the number shuld be 000, since n pwer ptimizers have been paired. S_OK: the cnnectin t the SlarEdge mnitring prtal is successful (shuld appear nly if the inverter is cnnected t the server). If S_OK is nt displayed and the inverter is cnnected t the server, refer t Errrs and Trubleshting n page 66. Vac [V]: the grid AC utput vltage. Verify the crrect value. 30

32 Chapter 5: Cmmissining the Installatin Vdc [V]: The DC input vltage f the lngest string cnnected t the inverter. There shuld be a safety vltage f 1V fr each pwer ptimizer in the string. NOTE A measurement errr n the inverter LCD f ±3 V is acceptable. Pac [w]: the AC utput pwer (shuld be 0.0 since the inverter is OFF). OFF: the inverter ON/OFF switch is in the OFF psitin. Step 2: Pairing Pwer Optimizers t the Inverter Once all cnnectins are made, all the pwer ptimizers must be lgically paired t their inverter. The pwer ptimizers d nt start prducing pwer until they are paired with an inverter. This step describes hw t assign each inverter t the pwer ptimizers frm which it will prduce pwer. Perfrm this step when the mdules are expsed t sunlight. If the string length is changed r a pwer ptimizer is replaced, repeat the pairing prcess. 1. Press and hld dwn the inverter LCD Light buttn fr abut 10 secnds. The fllwing message is displayed: K e e p h l d i n g b u t t n f r p a i r i n g, r e l e a s e t e n t e r m e n u...

33 Step 2: Pairing Pwer Optimizers t the Inverter 3. Wait fr the cmpletin f the pairing (remaining secnds is 0). If pairing fails, an errr is displayed. In this case, repeat the pairing steps, and refer t Pwer Optimizer Trubleshting n page 78. If the prblem persists, cntact SlarEdge Supprt. 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. NOTE 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 Standby mde until its wrking vltage is reached. This mde is indicated by the flickering green inverter LED. While the inverter is in Standby mde, it mnitrs the grid and verifies crrect grid vltage and frequency. The fllwing message is displayed: W a k i n g U p... R e m a i n i n g : S e c The cuntdwn indicates the secnds remaining until entering the Prductin mde. This time is in accrdance with lcal regulatins and is typically between three t five minutes. When cuntdwn is cmplete, the inverter enters Prductin mde and prduces pwer. The steadily lit green inverter LED indicates this mde. 32

34 Chapter 5: Cmmissining the Installatin Step 3: Verifying Prper Operatin After the wake-up time is ver, a status screen similar t the fllwing appears n the inverter LCD panel: V a c [ v ] V d c [ v ] P a c [ w ] P _ O K : X X X / Y Y Y < S _ O K > O N 1. Verify the fllwing: The green inverter LED is steadily lit. The ON/OFF indicatr n the LCD panel reads ON. P_OK: XXX/YYY: There is a cnnectin t the pwer ptimizers and at least ne pwer ptimizer is sending mnitring data. Optimizers send telemetries in a frequency f up t 10 minutes. Initially after pairing, bth XXX and YYY values shw 000 and the values increase as paired pwer ptimizers are reprted. NOTE It may take up t 20 minutes fr all pwer ptimizers t transmit their telemetries and t be cunted n the LCD screen. S_OK appears, if the inverter is cnnected t the SlarEdge mnitring prtal. Vac [V] specifies the measured grid AC utput vltage. Vdc [v] : Specifies the DC input vltage, which shuld equal the sum f the utput vltages f all mdules (and shuld be within the perating range f the inverter). Pac [W] specifies the ttal AC utput pwer prduced. 2. Take nte f the serial # n the inverter label using the detachable 2D barcde sticker n each device. This infrmatin is used in the SlarEdge mnitring prtal t identify this inverter and is needed t pen a new site in the mnitring prtal. Yur SlarEdge pwer harvesting system is nw peratinal. 33

109 Appendix E: Safe DC Appendix E: Safe DC When AC supply t the inverter is shut ff (by shutting ff the AC breaker at the site), r when the inverter ON/OFF switch is turned t OFF, the DC vltage drps t a safe vltage f 1V per ptimizer. The SlarEdge inverters are certified fr cmpliance with the fllwing standards as discnnectin devices fr PV generatrs, meaning that they can replace a DC discnnect: IEC : Crrigendum: A1: Crrigendum 1: A2:2005; DIN EN VDE : IEC : DIN VDE : In cmpliance with these standards, the discnnectin mechanism perates as fllws: 1. Turn the inverter ON/OFF switch, lcated at the bttm f the inverter, t OFF, r discnnect the AC by shutting ff the AC breaker at the site. The DC vltage displayed n the inverter LCD begins t decrease. If the AC breaker was shut ff, the LCD des nt display. In this case, wait five minutes. 2. When the DC vltage reaches a safe vltage, the PV cnnectrs at the input t the inverter can be discnnected. A galvanic separatin then exists between the PV array and the inverter. WARNING! Under single fault cnditins, the Safe DC vltage is nly guaranteed when using mdules f up t: 95Vc when using the single phase inverter 70Vc when using the three phase inverter 108
