Yuav tsum Nyob Hauv Lub Zog Cia Systems Siv Ib -theem lossis Peb-theem Inverters?

 

 

 

 

 

 

 

 

 

 

 

 

 

Kev txiav txim siab ntawm ib qho -theem thiab peb-theem inverter yog ib kauj ruam tseem ceeb hauv kev tsim thiab xaivnyob hauv lub zog cia systems, raws li nws cuam tshuam ncaj qha rau kev sib raug zoo nrog cov khoom siv hluav taws xob hauv tsev, txoj kev sib txuas ntawm kab sib chaws, thiab cov nqi tag nrho ntawm lub cev -kev ua tau zoo thiab scalability. Kev saws me nyuam thoob plawsthaj chaw PV thiab lub zog cia-ua ke nrog cov qauv sib txawv ntawm cov kab sib txawv thoob plaws cheeb tsam- tau ntxiv qhov nyuaj rau qhov kev xaiv no: ib zaug - cov kab ke feem ntau haum rau cov tsev qauv nrog cov khoom qis dua thiab cov qauv siv yooj yim, qhov thib peb - cov kab ke zoo dua rau cov tsev neeg lossis cov vaj tsev uas xav tau hluav taws xob siab thiab cov khoom siv hluav taws xob hnyav{4} xws li cov dej kub thiab dej txias. Kev nkag siab zoo ntawm cov xwm txheej siv thiab cov kev sib txawv ntawm cov txheej txheem yog qhov tseem ceeb los xyuas kom meej tias lub kaw lus ua haujlwm tau zoo thiab ua kom ruaj khov, ntev - rov qab mus rau lub sijhawm.

 

 

Ua ntej, qhia meej: Dab tsi yog ib qho -theem thiab peb -phase systems?

 

 

 

Qhov Tseem Ceeb Qhov Sib Txawv (Daim Ntawv Sib Piv Tseem Ceeb)

 

Comprehensive parameter sib piv ntawm hardware, kev ua tau zoo, thiab nqi.

 

 

Sib piv qhov ntev	Tib -phase inverter	Peb -phase inverter
Txheem voltage	Ib zaug -theem 220/230V	Peb-theem 380/400V (220V theem- rau- nruab nrab)
Mainstream zog ntau yam	3 kW/5kW/6kW/8kW/10kW	12kW/15kW/20kW/25kW/30kW
Sab hauv topology	Ib zaug -theem puv- choj ob- theem topology nrog cov suav qis qis.	Peb-theem, peb-theem NPC/ANPC topologies koom nrog ntau lub hwj chim thiab cov pawg tswj xyuas nyuaj.
AC kab hluav taws xob	L + N + PE 3-core cable	A / B / C + N + PE 5-core cable
Kab poob	Nrog rau siab - lub hwj chim loads, qhov nruab nrab tam sim no siab, uas ua rau muaj kev kub ntxhov loj.	Thaum lub load yog sib npaug, qhov nruab nrab tam sim no nyob ze rau 0, thiab tam sim no ntawm ib tug cable yog qis dua thiab qhov poob yog me me.
Hluav taws xob zog stability	Qhov tseem ceeb voltage fluctuations thiab siab dua harmonic theem nyob rau hauv hnyav load.	Cov zis tawm waveform yog du thiab peb -theem ntxiv, nrog tsawg voltage fluctuation thiab qis THD.
Load- nqa peev	Qhov siab tshaj plaws 10 kW ib chav tsev; tsis muaj zog peb- cov khoom siv theem (xws li peb -theem them pawg lossis cov twj siv dej ua haujlwm).	Muaj peev xwm ua kom muaj zog ib zaug ib zaug -theem khoom siv hauv tsev thiab siab- fais fab peb-theem loads; txhawb 1.1x nruam overload.
Tawm - daim phiaj thaub qab muaj peev xwm	Txhawb tsuas yog ib zaug xwb -theem loads; Tom qab hluav taws xob tawm, tag nrho lub tsev tsuas yog siv rau ib theem ntawm hluav taws xob.	Sib npaug peb- theem tso zis; muab lub zog rau tag nrho peb -theem circuits thoob plaws hauv lub tsev thaum muaj hluav taws xob.
Tag nrho cov nqi yuav khoom	qis; 20% -35% pheej yig dua rau tib lub zog tso zis.	Siab; cov nqi kho vajtse, algorithms, thiab thermal tswj yog siab dua.
Kev teeb tsa thiab kev tsim kho cov nqi	Yooj yim txuas; kev teeb tsa tuaj yeem ua tau los ntawm tus qauv hluav taws xob.	Yuav tsum muaj peb-theem fais fab mov thiab peb-phase faib lub thawv; cov nqi rau kev ua haujlwm thiab cov khoom siv txuas yuav nce ntxiv.
Kho nyuaj	Cov qauv yooj yim, ob peb lub ntsiab lus tsis ua haujlwm.	Kev tiv thaiv logic rau peb -theem tshuav nyiaj li cas thiab qhov tsis sib npaug yog qhov nyuaj, thiab cov kev xav tau ntawm kev tu thiab kho yog siab.
Siv tau daim phiaj fais fab	Feem coob ntawm cov tsev neeg zoo tib yam thoob plaws ntiaj teb muaj ib qho -theem fais fab txuas.	Cov xwm txheej cuam tshuam nrog peb -theem fais fab mov rau villas, tus kheej- ua tsev, ua liaj ua teb, thiab chaw lag luam lossis chaw tsim khoom.

 

 

 

 

 Hauv Tebchaws Meskas (tshwj xeeb hauv cov chaw xws li Chicago), ua tib zoo saib xyuas "split-theem" ​​system.

 

Lub zog nyob hauv Teb Chaws Asmeskas tsis yog ib qho nkaus xwb -theem; xwb, nws yog:

 

120/240V phua-theem (ob lub xov hlau kub + ib lub xaim nruab nrab).

 

Kev nkag siab txog kev teeb tsa cov kab hluav taws xob yog qhov tseem ceeb:

 

Hom Tsev Neeg Asmeskas	Pom zoo Inverters
Standard vaj tse (80% ntawm tsev neeg)	Tib -phase/split{1}}phase inverter (txhawb 120/240V)
Loj Villa / High Load	Split-theem siab-faiv fab lossis peb-phase systems (tsis tshua muaj)
Cov tsev lag luam	Peb -theem

 

 

 

Kauj ruam-los ntawm- kauj ruam xaiv thiab kev txiav txim siab (cov kauj ruam ua tau zoo)

 

Thawj kauj ruam: ua ntej saib koj tus kheej hauv tsev hluav taws xob daim phiaj hluav taws xob (qhov tseem ceeb ntawm qhov chaw)

 

1. The electricity meter has only 2 main wires (live wire + neutral wire) = single-phase into the home. Directly give priority to the single-phase inverter; if the total peak load is >10kW rau lub sijhawm ntev, ua ntej siv rau lub chaw muab hluav taws xob ntxiv rau peb theem, thiab tom qab ntawd hloov peb cov khoom siv -theem.

 

2. Lub ntsuas hluav taws xob ua rau 5 lub xov hlau loj (3 hluav taws, 1 xoom thiab 1 hauv av)=peb-theem mus rau lub tsev. Yog tias qhov load tsawg dua lossis sib npaug rau 10kW, ib zaug -theem tseem tuaj yeem xaiv; Yog hais tias lub load ntau dua los yog sib npaug rau 12kW thiab muaj ib tug them pawg / hluav taws xob boiler, peb{11}}theem tuaj yeem txuas ncaj qha.

 

Kauj Ruam 2: Xam lub siab tshaj plaws kev siv hluav taws xob ntawm tag nrho lub tsev

 

● Cov khoom siv hauv tsev ib txwm qhib rau tib lub sijhawm, tus nqi siab tshaj: 5–8kW → ib leeg-theem 6–10kW txaus;

 

● 1 7kW them pawg + nruab nrab cua txias + instant dej rhaub, ncov 12–18kW → yuav tsum yog peb-theem;

 

● 2 pawg them nyiaj + tag nrho- lub tsev hluav taws xob hauv pem teb cua sov, tus nqi siab tshaj 20kW → peb-theem 15–25kW.

 

Kauj ruam 3: Saib seb puas muaj hluav taws xob hluav taws xob backup (UPS off-grid function)

 

● Tsuas yog lub ncov thiab hav arbitrage, spontaneous tus kheej - siv, tsis xav tau lub zog cia rau lub hwj chim mov thaum lub sij hawm fais fab tuag: ib zaug -theem / peb-theem tau txais;

 

● Ib qho hluav taws xob hluav taws xob yuav tsum tau siv hluav taws xob tas mus li rau tag nrho lub tsev: qhov peb -theem kev paub zoo dua li ntawm ib zaug-theem (ib zaug-theem tsuas yog muab tau ib lub voj voog xwb, thaum peb-theem fais fab tuaj yeem xa mus rau tag nrho lub tsev).

 

Kauj Ruam 4: Ntsuas cov peev nyiaj thiab ntev - poob lub sij hawm

 

Luv-lub sij hawm txuag, me me hauv tsev, tsis tshua muaj load → ib zaug-theem; ntev -lub sij hawm siab zog, peb -theem tsev installation, tus kheej- tsev villas, nrhiav kev poob kab → peb-theem.

 

 

 

 

Kev xaiv zaum kawg

 

1.90% Ordinary urban lag luam vaj tse (ib zaug-theem tsev neeg, nyob rau hauv 100㎡, tsis muaj siab- fais fab them pawg) → ib zaug-theem zog cia inverter (3–10kW)

 

2. Ib leeg-tsev neeg villa/tus kheej- ua tsev (peb-theem tsev, ntau pawg them, hluav taws xob cua sov, tag nrho cov load saum toj no 12kW) → peb-theem zog cia inverter (12–25kW)

 

Yog tias ib zaug -theem tau teeb tsa hauv tsev tab sis qhov siab tshaj qhov load tshaj 10kW rau lub sijhawm ntev: ua ntej thov rau peb-theem muaj peev xwm nce, thiab tom qab ntawd yuav peb-theem inverter; nws tsis pom zoo kom txuas ntau qhov ib zaug -theem units nyob rau hauv parallel, vim tag nrho cov nqi yuav siab dua.
