Koj puas npaj yuav teeb tsa lub zog cia hauv tsev tab sis xav tias ntxhov siab los ntawm cov lus qhia? Los ntawm cov tshuab hluav taws xob thiab cov roj teeb mus rau cov kab hluav taws xob thiab kev tiv thaiv, txhua yam khoom siv ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj txiaj ntsig thiab kev nyab xeeb. Cia peb rhuav tshem cov ntsiab lus tseem ceeb los xav txog thaum xaiv koj qhov system.
Kauj ruam 1: Pib nrog lub Inverter
Lub inverter yog lub plawv ntawm koj lub zog cia, hloov DC lub zog los ntawm cov roj teeb rau AC fais fab rau tsev neeg siv. Nwslub zog ntsuasncaj qha cuam tshuam kev ua haujlwm thiab tus nqi. Txhawm rau txiav txim siab qhov loj me, suav kojpeak zog xav tau.
Piv txwv:
Yog tias koj qhov kev siv siab tshaj plaws suav nrog 2000W induction cooktop thiab 800W hluav taws xob kettle, tag nrho lub zog xav tau yog 2800W. Accounting rau tej zaum overrating nyob rau hauv cov khoom specifications, opt rau ib tug inverter nrog yam tsawg kawg nkaus3 kW zog(los yog siab dua rau kev nyab xeeb margin).
Input Voltage Teeb meem:
Inverters ua haujlwm ntawm cov voltages tshwj xeeb (xws li 12V, 24V, 48V), uas dictate koj lub txhab nyiaj roj teeb voltage. Siab dua voltages (xws li 48V) txo lub zog poob thaum lub sij hawm hloov dua siab tshiab, txhim kho tag nrho efficiency. Xaiv raws li koj qhov system qhov ntsuas thiab pob nyiaj siv.
Kauj Ruam 2: Xam cov roj teeb lub txhab nyiaj yuav tsum tau ua
Thaum lub inverter raug xaiv, tsim koj lub txhab nyiaj roj teeb. Rau 48V system, lithium hlau phosphate (LiFePO4) roj teeb yog ib qho kev xaiv nrov vim lawv txoj kev nyab xeeb thiab siv tau ntev. Lub roj teeb 48V LiFePO4 feem ntau muaj16 cell hauv series(3.2V ib lub cell).
Cov qauv tseem ceeb rau kev ntsuas tam sim no:
Kom tsis txhob overheating, xam covMaximum ua haujlwm tam sim nosiv ob txoj kev:
1.Inverter-raws li xam:
Tam sim no = Inverter Fais fab (W) Input Voltage (V) × 1.2 (kev nyab xeeb yam) Tam sim no = Input Voltage (V) Inverter Fais fab (W) × 1.2 ( yam muaj kev nyab xeeb)
Rau 5000W inverter ntawm 48V:
500048 × 1.2≈125A485000 × 1.2≈125A
2.Cell-Based Calculation (Ntau Conservative):
Tam sim no = Inverter Fais fab (W) (Cell Count × Yam tsawg kawg nkaus tawm Voltage) × 1.2Current = (Cell Count × Yam tsawg kawg nkaus tawm Voltage) Inverter Fais fab (W) × 1.2
Rau 16 hlwb ntawm 2.5V tawm:
5000 (16 × 2.5) × 1.2≈ 150A (16 × 2.5) 5000 × 1.2≈ 150A
Kev pom zoo:Siv txoj kev thib ob kom muaj kev nyab xeeb dua.
Kauj Ruam 3: Xaiv Cov Khoom Siv Hluav Taws Xob thiab Kev Tiv Thaiv
Cables thiab Busbars:
- Output Cables:Rau 150A tam sim no, siv 18 sq.mm tooj liab hlau (nyob ntawm 8A / mm²).
- Inter-cell Connectors:Xaiv rau 25 sq.mm tooj liab-aluminium composite busbars (nyob ntawm 6A / mm²).
Kev tiv thaiv Board (BMS):
Xaiv ib150A-rated roj teeb tswj qhov system (BMS). Xyuas kom meej meejtsis tu ncua tam sim no muaj peev xwm, tsis nco qab tam sim no. Rau kev teeb tsa ntau lub roj teeb, xaiv BMS nrogparallel tam sim no-limiting muaj nuj nqilos yog ntxiv ib qho kev sib txuas sab nraud kom sib npaug loads.
Kauj ruam 4: Parallel roj teeb Systems
Lub zog cia hauv tsev feem ntau xav tau ntau lub tsev txhab nyiaj roj teeb ua ke. Sivntawv pov thawj parallel moduleslos yog BMS nrog built-in ntsuas los tiv thaiv tsis sib xws them / tso tawm. Tsis txhob txuas cov roj teeb uas tsis sib xws kom txuas tau lub neej ntev.
Cov Lus Qhia Kawg
- Ua ntejLiFePO4 Cellrau kev nyab xeeb thiab lub neej voj voog.
- Txheeb xyuas cov ntawv pov thawj (xws li UL, CE) rau txhua yam khoom.
- Tham nrog cov kws tshaj lij rau kev teeb tsa nyuaj.
Los ntawm kev kho koj lub inverter, roj teeb lub txhab nyiaj, thiab cov khoom tiv thaiv, koj yuav tsim kom muaj kev ruaj ntseg, txuag hluav taws xob hauv tsev. Rau kev dhia dej tob, mus saib peb cov lus qhia ntxaws ntxaws txog kev ua kom zoo dua lithium roj teeb teeb!
