1. HYD‐ESinverterIntroduction
TheHYD‐EShybridinverterisusedinPVsystemwithbatterystorage.
EnergyproducedbythePVsystemwillbeoptimizedformaximumself‐consumption.
TheHYD‐ESinvertercanworkinautoortime‐of‐use(TOU)mode,charge/dischargethebatterywhenneeded.In
automode,theHYD‐ESinverterwillchargesurplusPVenergyintothebattery&dischargebatterytosupplypowerto
localloadwhenPVenergyisnotenough.
Incaseofblackout,HYD‐ESinvertercanworkinEmergencyPowerSupply(EPS)mode.HYD‐ESinverterwillutilize
powerfromPVpanels&energystoredinthebatterytosupplypowertocriticalload.

safetyrulesofdesignandtesting.Duringtheinstallation,operationandmaintenance,operatorsshouldabidebylocal
safetyregulations.Improperoperationmaycauseanelectricshockordamagetheequipmentandproperties.
2.1. SafetyNotes
Electricalinstallationandmaintenancemustbecarriedoutbycompetentelectriciansaccordingtolocal
regulations.
HYD‐ESinvertercanonlybeinstalledbyqualifiedelectrician,andonlythosewhohaveappropriateaccreditation,

6.2. FirstTimeSetup(IMPORTANT!)
IMPORTANT:PLEASEFOLLOWTHEFOLLOWINGPROCEDUREtoswitchONHYD‐ESinverter
1. Makesurethere’snopowergenerationinHYD‐ESinverter’sphase.
2. TurnONDCswitch.
3. SwitchONthebattery.TurnONDCisolatorbetweenbattery&HYD‐ESinverter.
4. TurnONACcircuitbreakerbetweentheHYD‐ESinverterGRIDport&GRID.
5. TurnONACcircuitbreakerbetweentheHYD‐ESinverterLOADport&criticalload.
6. HYD‐ESinvertershouldstarttooperatenow.

YouneedtosetthefollowingparametersbeforeHYD‐ESinverterstartstooperate.
1)Setsystemtime8)*Setmindischargevoltage
2)Setcountry9)*Setmaxdischargecurrent
3)Selectbatterytype10)*Setminprotectvoltage
