Setting the Inverter to Support 208V 3-wire Grid
SolarEdgeinvertersthatsupportthe208V3-wiregridareequippedwithtwofuseholdersandafusein
eachunit.ThepositionofthefuseconfigurestheACgridconnection:4-wireor3-wiregridconnection.
Bydefault,thefuseislocatedinthe4-wirefuseholderoftheinverter,andinthe3-wirefuseholderthere
isaplasticdummyfuse.
Tosettheinverterfor3-wiregridconnection,youmustmovethefusefromthe4-wirefuseholder,
markedasYGRID,tothe3-wirefuseholder,markedas∆GRID(seeFigure32).
To set the inverter for 208V 3-wire grid connection:
NOTE
Perform this procedure for all inverter units.
NOTE
Perform this procedure before connecting the inverter to the AC grid.
1.
IdentifythefuselocationsandthemarkingsasdescribedinFigure32.
Figure 32: Fuse locations and markings
2. Removethedummyfusefromthe3-wiregridfuseholderandsetitaside.
3. Movethefusefromthe4-wiregridfuseholdertothe3-wiregridfuseholder.
4. Placethedummyfuseinthe4-wiregridfuseholder.
5. Duringsystemsetup,setthecountrytotheappropriate3-wiregridoption.Usingthenon-3-wire
settingmayresultinincorrectsystemoperation.
CAUTION!
If the fuse was moved to support one of the grid types, do not connect the inverter to the other grid type
without switching the fuse back to the correct holder. Connecting the inverter to grids when the fuse is
incorrectly located may damage the inverter and void the warranty.
Si le fusible a été déplacé pour supporter l’un des types de réseau, ne branchez pas l’onduleur sur l’autre
type de réseau avant de remettre le fusible dans son bon support. Brancher l’onduleur au réseau quand
le fusible est mal placé, peut endommager l’onduleur et annuler la garantie.
