IMPORTANT INVERTER SAFETY INSTRUCTIONS13CAUTION!This unit must be operated according to the technical specification datasheetprovided with the unit.ATTENTION!Cette unité doit être utilisée selon les spécifications de fonctionnement, commedécrit dans la dernière fiche technique des spécifications.CAUTION!HEAVY OBJECT. To avoid muscle strain or back injury, use proper liftingtechniques, and if required - a lifting aid.ATTENTION!Objet lourd. Pour éviter la fatigue musculaire ou des blessures au dos, utilisezdes techniques de levage appropriées et, si nécessaire - un auxiliaire de levagelors du retrait.NOTEThe StorEdge Connection Unit is NEMA type 3R rated . Unused conduitopenings and glands should be sealed with appropriate seals.NOTEUse only copper conductors rated for a minimum of 75 C/ 167 F.NOTEThis inverter is provided with an IMI (Isolation Monitor Interrupter) for groundfault protection.NOTEThe symbolappears at grounding points on the SolarEdge equipment. Thissymbol is also used in this manual.NOTEA SolarEdge inverter may be installed in a site with a generator, however mustnot operate at the same time as the generator.Operating an inverter and a generator simultaneously will void the warranty.SolarEdge requires installing a physical or electronic interlock, which willprevent the generator and inverter from operating simultaneously. Interlockprocurement, installation, maintenance and support are the responsibility ofthe installer. Damage to the inverter due to incorrect interlock installation oruse of an interlock that is incompatible with the SolarEdge system will renderthe SolarEdge warranty invalid.StorEdge Solution with Backup MAN-01-00262-1.6

16 Chapter 1: OverviewChapter 1: OverviewStorEdge is SolarEdge's all-in-one solution that uses a single phase DC optimizedinverter to manage and monitor both solar power generation and energy storage.Homeowners are automatically provided with backup power in the event of gridinterruption to power pre-selected loads. Solar energy can be stored in a battery forSmart Energy Management applications such as export control, offering demandresponse and peak shaving, and performing time of use shifting for reduced electricbills.The StorEdge Solution ComponentsThe StorEdge Inverter - The inverter manages battery and system energy, inaddition to its traditional functionality as a DC-optimized PV inverter.The StorEdge Connection Unit, located at the bottom of the inverter, allowssimple installation and connectivity to other system components and includes aDC Safety Switch.The Energy Meter - The meter is used by the inverter for export, import,production and consumption readings, and for Smart Energy Managementapplications, such as: export limitation, time-of-use profile programming andmaximizing self-consumption.The meter is required only in systems using Smart Energy Managementapplications (it is not required for StorEdge systems used only for backuppower).The Auto-transformer - The auto-transformer handles the phase loadbalancing. It is required only in systems providing backup power.One or two batteries - DC coupled batteries desi
