2. Introduction

2.1 GeneralDescription
TheSTS(StaticTransferSwitch)moduleincreasessystemreliabilitybyautomaticallyswitchingbetweenthe
inverteroutputandtheACmains.Bysettingupthepriorityofoperation,userscanchangethesystem
statusto“onlinemode”or“offlinemode”.Theonlinemodewillsupplypowertotheloadfromthe
inverters.Incaseofaninverterfailureoroverload,theSTSwillswitchtheloadtotheACutility.In
offlinemodetheloadisalwaysconnectedtotheACutilityandwillswitchtotheinvertersintheeventof
ACutilityfailure.Thetransfertimeislessthan1/4cyclewhichavoidsanypowerinterruptiontotheload.
ThereliableperformanceoftheSTSmoduleprovidedmaximumprotectionagainstpossibledamageorloss
ofservicecausedbypowerfailure.

2.6.2 Voltage&FrequencyRange
TheSTSmodulehastwoinputsandoneoutput.
ThetwoinputsareMainsinputandInverterinput;theoutputisSystemoutput.
TheSTSwilldetectMainsvoltageandInvertervoltageinordertodecidesystem’ssupplymodewhenthe
systemisrunning.
IfbothMainsandInverterinputsarepresent,bydefaultMainshasprioritytodecidetheoperationalstatus
ofsystem;i.e.theSTSwillfirstlyconsiderMainsstatustodecidesystem’srunningvoltageandfrequency.
Followingconfirmationofvoltageandfrequency,theover/undervoltageandover/underfrequencyisset
asinthefollowingtables.

Note that the STS can be set to ‘online’ or ‘offline’ priority using the controller.

3.2 Handling&Storage
IftheSTSmodule,shelfandMBSunitaregoingtobestoredpriortoinstallation,theyshouldbeplacedina
cool,dry,well‐ventilatedlocationfreefromrain,splashingwater,chemicalagents,etc.Theequipment
shouldbestoredinitsoriginalpackingmaterialuntilitisgoingtobeinstalled.
TheSTSmodulecanberemovedfromtheshelfbydrawingoutthehandle.Firstly,unscrewthesteelbolt,
thenpulloutthehandleuntilthewholemodulehasbeenremoved.WhentheSTSmodulehastobe
installedintheshelf,theboltshouldbescrewedintolockitinplace.
3.3 Location
Thesystemisdesignedforinstallationinaprotectedenvironment.Factorstobeconsideredinselectinga
locationincludeventilation,temperature,humidity,andaccessibility.Installthesysteminaclean,dry
locationwithanunrestrictedairflowandsufficientspaceforrearandfrontaccess.Maximum
performanceisavailableinambienttemperaturesfrom‐5°Cto50°C.Higherambienttemperatureswill
leadtoashorterlifetimeunlessthesystemcapacityisappropriatelyderated.Gassesemanatingfromthe
batterycanbecorrosiveandhighlyflammable,soisolatethesystemfromthebatterysourceasmuchas
possible.
