3.4 ElectricalConnection
Youmustcomplywiththeconnectionrequirementoflocalregulations.
The inverter is integrate with an RCMU according to VDE0126‐1‐1/ A 1 .  It
monitorsresidualcurrentfromthesolarmoduletogridsideofinverter.The
inverter can automatically differentiate between fault current and normal
capacitiveleakagecurrents.
Itmustbeinclude
dabreakerorafuseattheACside,acbreaker’s
norminalvoltageis400Vac,the meltingcurrentisnotlargerthan
16A.
The equipment should have a protective earthing attached to earth
conductor.

3.4.1 ConnectiontoGrid(ACSideConnection)
A Checkthegrid(utility)voltageandfrequencyattheconnectionpointof
theinverter.Itshouldbephasetophase400VAC,50Hzandthreephases.
BChecktheratingofbranchcircuitbreaker.Forinstallingoneunitof4‐6K
inverter,therecommendedbreakerratingis400V/16A.
C Disconnectthebr
eakerorfusebetweenPV‐Inverterandutility.
D  Connecttheinvertertothegridasfollows:
` SwitchofftheACBreaker.
