1 yooj yim configuration
Ib txheej ntawm cov hluav taws xob tsim hluav taws xob tsim nrog cov hnub ci ntsa iab, photovoltaic inverters thiab AC Circuit breakers. Lub teeb theem pib muaj nyob hauv daim duab hauv qab no. Lub koob yees duab photovoltaic ntawm cov qauv ntawm photovoltaic converts hnub ci zog mus rau cov khoom siv hluav taws xob tam sim no. Tus inverter ua raws li ib chav nyob nruab nrab kom hloov tau lub zog DC no rau AC zog uas ua tau raws li qhov yuav tsum tau ntawm daim phiaj thiab xa mus rau hauv kab.

2 cov khoom siv loj
2.1 Cov hnub ci qauv

Cov hnub ci ntsa iab siv XXX hnub ci qauv, thiab nws cov kev ua tsis tau yog muaj nyob rau hauv qab rooj.

2.2 Photovoltaic inverter

Cov photovoltaic inverter siv XXX hom PV inverter, thiab nws cov tswv yim thiab cov zis tsis qhia nyob rau hauv cov lus hauv qab no.

Lub hauv paus ntawm txoj cai ntawm tus qauv hluav taws xob ntawm cov hlua hluav taws xob hauv PV yog pom nyob rau hauv daim duab nram qab no, uas feem ntau muaj xws li DC EMC lim, MPPT thiab boost circuit, inverter, tiv thaiv Circuit Court, AC EMC lim thiab tib neeg-tshuab interface thiab kev sib txuas lus. seem.

Tus inverter tso cai rau ib txoj hlua PV txoj hlua. Tus inverter configures ib MPPT tracker rau lub tswv yim PV kom paub tseeb tias cov hlua DC uas tau tsim los ntawm cov hlua ntawm PV yog qhov dav ntawm qhov inverter. Qhov teeb meem hauv inverter sib txuas ncaj ncaj tam sim no mus ua lwm yam zog tam sim no. Txoj kev tiv thaiv kev ua haujlwm tiv thaiv xyuas cov haujlwm thaum lub sijhawm ua haujlwm ntawm lub inverter, thiab ua rau sab nraud relay nyob rau hauv kev ua haujlwm tsis txawv txav los tiv thaiv cov khoom sab hauv ntawm kev tsim txom. Ntxiv mus, DC qhov kev nyab xeeb siv tawm ntawm DC tam sim no. Lub tshuab inverter muaj ib tug tib neeg-lub computer interaction interface rau kev khiav lag luam thiab kev tso tawm, uas siv tau rau cov txij nkawm thiab cov neeg saib cov ntaub ntawv qhia txog cov sij hawm los yog keeb kwm ua haujlwm, nrog rau cov ntaub ntawv qhia txog khoom. Tsis tas li ntawd, inverter RS485 interface muab kev saib xyuas kev noj qab haus huv ntawm tag nrho PV hnub ci vaj huam sib luag mounting system.

3 cov khoom siv installation
Qhov hluav taws xob hauv hluav taws xob muaj xws li DC txuas hluav taws xob, AC sab hluav taws xob txuas thiab kev sib txuas lus txuas hluav taws xob txuas.

3.1 Daim qauv txuas hluav taws xob

3.2 Inverter sab nraud thaiv

Lub davhlau ya dav hlau thaiv sab nraud yog nyob hauv qab ntawm qhov inverter raws li qhia hauv qab no. Xws li sab nraud DC, AC sab, thiab kev sib txuas lus txuas lus. Qhov no ua rau kev txuas hluav taws xob tsis qhib lub hau npog ntawm lub inverter thiab cov terminals tag nrho hauv cov kab dej tsis muaj dej, uas ua kom muaj kev ruaj ntseg ntawm cov neeg ua hauj lwm thiab cov xov hluav taws xob yooj yim.

3.3 Kev Sib Txuas Lus Kab Mob

3.4 AC side hluav taws xob txuas

Cov kab sib txuas nrog txoj hlua hom XXX PV inverter yuav tsum muaj cov xwm txheej hauv qab no, txwv tsis pub lub inverter yuav tsis ua haujlwm.

Grid voltage: 174 ~ 274V;

Txuas zaus npaum li cas: 47 ~ 53Hz / 57 ~ 63Hz;

Tus inverter txuas nrog lub kab sib chaws ntawm peb lub xov hlau (L, N thiab PE). Lub interface rau ntawm daim phiaj yog AC lub davhlau ya nyob twg, thiab lub hwj huam pub rau hauv daim phiaj yog ib theem xwb. (Sunshine fais fab mov muab tus AC connector coj mus rau AC side hluav taws xob kev txuas ntawm lub inverter).

3.5 AC Circuit Court breaker

Yuav kom tiv thaiv tau lub inverter AC circuit thiab kev nyab xeeb ntawm tus kheej thaum lub sij hawm thaiv, ob lub voj hluav taws xob Circuit Court yog teeb tsa ua ib qho kev tiv thaiv rau txhua lub inverter. Nws raug pom zoo tias AC breaker luv luv tam sim no yuav tsum yog 13A.

3.6 Hnub ci PV vaj huam sib luag

Vim tias txoj hlua hom XXX photovoltaic inverter yog ib hom tsis yog, nws yuav tsum muaj qhov zoo electrode thiab tsis zoo electrode ntawm tus photovoltaic array tsis tau grounded, txwv tsis pub tus inverter yuav irreparably puas.

Hauv no lub tshuab fais fab tuag lub zog, tag nrho cov khoom tsis yog tam sim no thiab cov khoom siv cov hlua yuav tsum txuas nrog lub ntiaj teb, xws li lub hnub ci vaj huam sib luag mounting qauv kev txhawb nqa ntawm photovoltaic modules, inverter casings, thiab lwm yam.

Daim duab ntawm daim duab tso rau hauv qab no

3.7 Kev sib txuas lus sib txuas lus

Kev sib txuas lus ntawm RS485 tuaj yeem siv los pauv cov lus qhia kev lag luam hauv lub lag luam hauv lub computer lossis lub zos cov ntaub ntawv khaws cia (xws li SolarInfo Logger) uas tau xyuas software (xws li SolarInfo Insight).

Yog tias tsuas yog ib qho inverter, RS485 kev sib txuas xov txuas nrog lub tshuab fais fab siv tau rau kev sib txuas lus.
