Njengoko iinkqubo zokugcina amandla elanga ziya zithandwa kakhulu, abaninzi abantu baqhelene neeparameters eziqhelekileyo ze-inverters zokugcina amandla. Nangona kunjalo, kusekho ezinye iiparameters ezifanele ukuqondwa nzulu. Namhlanje, ndikhethe iiparamitha ezine ezihlala zingahoywa xa ukhetha ii-inverters zokugcina amandla kodwa zibalulekile ekwenzeni ukhetho olufanelekileyo lwemveliso. Ndiyathemba ukuba emva kokufunda eli nqaku, wonke umntu uya kukwazi ukwenza ukhetho olufanelekileyo xa ejongene neemveliso ezahlukeneyo zokugcina amandla.
01 Uluhlu lweBattery Voltage
Okwangoku, ii-inverters zokugcina amandla kwimarike zohlulwe zibe ziindidi ezimbini ezisekwe kumbane webhetri. Olunye uhlobo lwenzelwe i-48V yeebhetri zamandla ombane, ezinoluhlu lwamandla ombane webhetri ngokubanzi phakathi kwe-40-60V, eyaziwa ngokuba yi-low-voltage yokugcina amandla ebhetri. Olunye uhlobo lwenzelwe iibhetri eziphezulu ze-voltage, ezinoluhlu lwebhetri oluguquguqukayo, oluhambelana kakhulu neebhetri ze-200V nangaphezulu.
Isincomo: Xa kuthengwa ii-inverters zokugcina amandla, abasebenzisi kufuneka bahlawule ingqwalasela ekhethekileyo kuluhlu lwe-voltage i-inverter enokuthi ifake kuyo, iqinisekisa ukuba ihambelana nombane wangempela weebhetri ezithengiweyo.
I-02 Ubuninzi be-Photovoltaic Input Power
Amandla okufakelwa kwe-photovoltaic aphezulu abonisa amandla amaninzi inxalenye ye-photovoltaic ye-inverter inokwamkela. Nangona kunjalo, la mandla ayingowona mandla aphezulu anokuphatha i-inverter. Ngokomzekelo, kwi-inverter ye-10kW, ukuba amandla okufakelwa kwe-photovoltaic aphezulu angama-20kW, i-AC ye-AC ye-inverter ephezulu iseyi-10kW kuphela. Ukuba i-20kW photovoltaic array iqhagamshelwe, kuya kubakho ukulahleka kwamandla kwe-10kW.
Uhlalutyo: Ukuthatha umzekelo we-GoodWe inverter yokugcina amandla, inokugcina i-50% yamandla e-photovoltaic ngelixa ikhupha i-100% AC. Kwi-inverter ye-10kW, oku kuthetha ukuba inokuvelisa i-10kW AC ngelixa igcina i-5kW yamandla e-photovoltaic ebhetri. Nangona kunjalo, ukudibanisa uluhlu lwama-20kW kuya kuchitha i-5kW yamandla e-photovoltaic. Xa ukhetha i-inverter, ungacingi nje kuphela ubuninzi be-photovoltaic igalelo lamandla kodwa kunye namandla okwenene i-inverter inokusingatha ngaxeshanye.
03 Ukukwazi ukuNxibelela kwi-AC
Kwii-inverters zokugcina amandla, icala le-AC ngokubanzi liqulethe imveliso eboshwe ngegridi kunye ne-off-grid output.
Uhlalutyo: Imveliso eboshwe kwigridi ngokuqhelekileyo ayinakho ukugqithiswa kwamandla ngenxa yokuba xa ixhunyiwe kwigridi, kukho inkxaso yegridi, kwaye i-inverter ayifuni ukusingatha imithwalo ngokuzimeleyo.
Imveliso engaphandle kwegridi, kwelinye icala, ihlala ifuna amandla okulayisha ngaphezulu kwexesha elifutshane kuba akukho nkxaso yegridi ngexesha lokusebenza. Umzekelo, isiguquli sogcino lwamandla esisi-8kW sinokuba namandla aphuma kwigridi ereyithiweyo ye-8KVA, kunye nowona mandla uphezulu abonakalayo aphuma kwi-16KVA ukuya kuthi ga kwimizuzwana eyi-10. Eli xesha le-10-yesibini lidla ngokwaneleyo ukujongana nokunyuka kwangoku ngexesha lokuqalisa kwemithwalo emininzi.
04 Unxibelelwano
Unxibelelwano lonxibelelwano lwee-inverters zokugcina amandla ngokubanzi lubandakanya:
4.1 Unxibelelwano kunye neebhetri: Unxibelelwano kunye neebhetri ze-lithium ludla ngonxibelelwano lwe-CAN, kodwa iiprothokholi phakathi kwabavelisi abahlukeneyo zinokwahluka. Xa uthenga ii-inverters kunye neebhetri, kubalulekile ukuqinisekisa ukuhambelana ukuphepha imiba kamva.
4.2 Unxibelelwano kunye neePlatform zokuHlola: Unxibelelwano phakathi kwee-inverters zokugcina amandla kunye neeplatifomu zokubeka iliso zifana ne-grid-tied inverters kwaye zingasebenzisa i-4G okanye i-Wi-Fi.
4.3 Unxibelelwano kunye neeNkqubo zoLawulo lwaMandla (EMS): Unxibelelwano phakathi kweenkqubo zokugcina amandla kunye ne-EMS ngokuqhelekileyo isebenzisa i-RS485 enengcingo enonxibelelwano oluqhelekileyo lwe-Modbus. Kusenokubakho iyantlukwano kwiiprothokholi ze-Modbus phakathi kwabavelisi be-inverter, ke ukuba ukuhambelana ne-EMS kuyafuneka, kuyacetyiswa ukuba unxibelelane nomvelisi ukuze ufumane itafile ye-Modbus protocol point phambi kokukhetha isiguquli.
Isishwankathelo
Iiparamitha ze-inverter yokugcina amandla zinzima, kwaye ingqiqo emva kwepharamitha nganye ichaphazela kakhulu ukusetyenziswa okusebenzayo kwee-inverters zokugcina amandla.
