The minimum and maximum string lengths are specified in the pwer datasheets. Refer t the SlarEdge Site Designer fr string length verificatin. NOTE l l Use at least 11 AWG/ 4 mm² DC cables. The ttal cnductr length f the string (excluding pwer ptimisers cnductrs; including hme runs and necessary extensins between ptimisers) shuld nt exceed: Fr inverter mdels SE14.4K and SE33.3K ft./ 700 m frm DC+ t DC- f the inverter IMPORTANT SAFETY FEATURE l l Fr a cmpliant PV Rapid Shutdwn (PVRSS) installatin, use n mre than 30 ptimisers per string. Enabling PVRSS frm the inverter menu is nly required if the installed ptimisers were manufactured befre 2015, therwise it is enabled by default. NOTE The DC bus f each unit is separate and nt shared fr all units. Therefre in additin t fllwing the inverter design rules, each unit shuld fllw the unit design rules as detailed in the Technical Specificatins. 1. Cnnect the Minus (-) utput cnnectr f the string s first pwer ptimiser t the Plus (+) utput cnnectr f the string s secnd pwer ptimiser. 2. Cnnect the rest f the pwer ptimisers in the string in the same manner. Figure 9: Pwer ptimisers cnnected in series 3. If yu intend t mnitr the installatin, using the SlarEdge mnitring platfrm, recrd the physical lcatin f each pwer ptimiser, as described in Prviding Installatin Infrmatin n page

21 Step 4: Verifying Prper Pwer Optimizer Cnnectin Step 4: Verifying Prper Pwer Optimizer Cnnectin When a mdule is cnnected t a pwer ptimiser, the pwer ptimiser utputs a safe vltage f 1V (±0.1V). Therefre, the ttal string vltage shuld equal 1V times the number f pwer ptimisers cnnected in series in the string. Fr example, if 10 pwer ptimisers are cnnected in a string, then 10V shuld be prduced. Make sure the PV mdules are expsed t sunlight during this prcess. The pwer ptimiser will nly turn ON if the PV mdule prvides at least 2W. In SlarEdge systems, due t the intrductin f pwerptimisers 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 ptimiser 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.
