Inverter Operation34 Power Xpert Solar 1500/1670 kW Inverter MN141001EN—October 2014 www.eaton.com● The inverter does not provide a means to isolate utilityvoltage on the transformer-side of circuit breaker CB4 orany additional control-power disconnect(s) which arelocated inside the inverter AC cabinet (section)● The inverter does not provide a means to isolate inputcircuits from the PV-array (system) side of disconnectsDS1, DS2, and DS3, which are located inside the inverterDC cabinet (section). Unless the PV-array is fullydisconnected externally from the inverter, the inverterre-combiner will be energizedDe-Energized Inverter1. Verify the inverter is in the OFF state2. The inverter will de-energize stored capacitive-energywhen in the OFF state.a. and CB1, CB2, CB4, DS1, DS2, and DS3 and areverified opened.b.Notice: the inverter will remain energized unless thetransformer is also disconnected or isolated form theutility grid and completely de-energized. The inverter’sthroat-connection is a direct feed from thetransformer.c. Notice: the inverter will remain energized unless theexternal PV-disconnects are fully open. DisconnectsDS1 DS2 and DS2 do not isolate the inverterre-combiner from the PV array system.● Pressing the emergency stop switch will also shut-off theinverter, forcing open CB1, DS1, DS2, and DS3, but notCB2 or CB4.a. Notice: the inverter control power and transformer willremain live.b.Notice: the inverter re-combiner will remain energizedfrom the PV.● Wait at least 5 minutes to allow the stored capacitiveenergy to dissipate before opening the cabinet doors andaccess panels.● Always VERIFY no-voltage is present using calibratedinstruments appropriate to the voltage.● Always follow applicable safety requirements andequipment labeling when verifying voltage● Follow defined LOTO procedures prior to servicing theinverter● PV Systems: Understand and verify all sources of externalpower connected to the inverter, including backfeed fromthe photovoltaic system, other inverters, loop-feedtransformers and their common points of utilityconnection.Interactive MenuThe HMI’s LCD touch-screen provides information pertainingto the inverter’s present and historical operating status andprovides access to user adjustable parameters. Navigationthrough the menus is achieved through a combination ofmenu screens icons, each with subsequent touch screensub-menus. After the duration of 15 minutes the display willalways return to the default screen of the current menu.Five main menus are available for operating the inverter,obtaining information from the inverter, andtroubling-shooting. Figure 27 illustrates the menu structureand available screensScreen Notes:● Menus ICONS are located along the bottom of the screen● The icons are similar to a Footer on a printed page● Operational status is located in the top-left corner, forexample;● OFF● Sleep● Wake-up● Export● Fault● Based upon the menu, selective information is displayedthrough the screen between the top and bottom sections
