Kulokho kwezindlela zokuthenga zabaB2B, njengezindawo zokuthenga, abasebenzi bokugcina izinhlangano, nabathengi beziprojekthi zemithambo, ukukhetha amaphetha okuhlanganisa okufanele akuyi into esiphambili ekubhekiseni kumsebenzi wendawo, ukuzimisela kwezinhlelo zokusebenza, nokuphatha kwezinkampani ngeminyaka eyadlule. Amaphutha ethu ethintela ngokuphindwe bayi izinyawo zezinhlangano zokusebenza zempilo yezinsiza nezinkampani zokugcina amandla, futhi baprosesa ukuthenga kwezinsiza, ukugcina/ukususa kwezinkampani, nokuxhumana nesikhungo. Izinto ezintathu eziphambili zokuthenga kwezindawo zabaB2B zizichazwa phezulu.
Izinqakamba Zokusebenza Ezibalulekile: Ukulinganisa Kwamandla, Isikhundla SeMPPT, Nokuvumelana Nokugcina Amakhemikali
Ukukhetha kwamaphetha okuhlanganisa kunezinqakamba ezintathu zokusebenza.
Isivumelwano sesithunzi sisibonisa isilinganiso sesithunzi nesibhodi sesithunzi esinokubalwa ngokuphelele ngokusebenza kwe-inverter. Abakholi baseB2B bafanele ukuthi bahlukanise isivumelwano sesithunzi ngokufanayo nokuthi baphatha iziprojekthi zabo zokusebenzisa- iziprojekthi zokuzilolwa zizihlukanisa izinkampani zokusebenza kwe-3kW-10kW futhi izisakhiwo sezimboni zizihlukanisa izinkampani zokusebenza kwe-10kW-100kW noma kakhulu. Yenza ubuningi lokukhombisa isilinganiso sesithunzi sokugcina (AC) nesilinganiso sesithunzi sokungena (PV).
Isilinganiso sesi-MPPT (Ukutshaba Kwe-Point Yokubaluleka Kwesithunzi) nangokubhalwa kwesi-MPPT kunezimpikiswano eziningi zokuthi kuyiphi indawo yokususa amandla. Ngezilinganiso eziphelele zesi-MPPT (isibhalo: 150 V ku-800 V) singasiza ekutheni sibhalwe kahle amapaneli futhi singaqala kahle emazulwini apho kunezikhathi ezincinci zokushisa. Ukubhalwa kwezinye izi-MPPT zikuphula ukuphula kwezindlela zokuhlanza okuncane, okuyisidingo esiphambili kwezisakhiwo zemphakathi ngezindlela zokuhlukaniswa zokuzilolwa.
Ukuhambanana kwe-battery kuyabecala kubalulekile kuma-hybrid inverter. Kusukela kwe-battery voltages (48 V, 96 V noma high-voltage 400 V+), amaprothokholi we-communication (CAN bus, RS485), futhi kungakwenzeka nge-lithium iron phosphate (LiFePO4) batteries, okuyisibonelo esihlukile kakhulu se-energy storage. Amasinye ama-inverter ayisibonelo se-battery-agnostic, noma kufuneka izibhalo zezibhalo zokuzimela noma izibhalo zokuzimela.
Ukuhambanana kwe-grid nezinqakambo zokuhlanzwa kuma-makheti emhlabeni wonke
Abakhasi base-B2B abasebenzisa emakhetini emhlabeni kufanele baphinde baphinde ngama-grid codes noma izinqakambo zokuhlanzwa. Okuyindlela yokuqiniseka kwe-inverter ekhaya kungayindlela yokuqiniseka kwe-inverter ekhaya kwenye indawo.
Izinqakambo eziphambili ezifanele ukuzilandelwa ziyizinto ezilandelayo:
IEC/EN 62109 (isivumelwano sokuvikela kwe-power converters)
VDE-AR-N 4105 (Jalimani), G98/G99 (UK), UL 1741 (North America), noma AS/NZS 4777 (Australia) yokuhambanana kwe-grid
CE, FCC, RoHS kuma-makheti e-Europe nase-North America
ISO9001, ISO14001 yokuphatha ubuquality nokuphatha umhlaba ngokwesifundo kusuka kumshini
Abathengi bafanele bakwazi ukubiza izirayela zokuphatha kwe-grid ezifundwa ngemithombo yezifundo eziqinisekisiwe. Kukhona izindlela zokuphatha ezinye zokuphatha kwe-grid (ukusika kwesikhumbuzo, imithombo yezindawo ezingenakho) noma izirayela ze-GB/T (China) noma EN 50155 (isikhumbuzo) kuma-projekthi eminkaneni yezinsizakalo. Sibhekisele ku-ma-manufacturers abanenqinisekiso yezifundo eziphezulu kuma-markethi okufuna ukuthengisa kuyo.
Ukugcina kwe-OEM/ODM nokuhlelwa kwezinsizakalo ngaphandle kwezinsizakalo
Izinsizakalo ze-OEM ne-ODM ziyizinto ezingavumeli ukuthi izinsizakalo nezinsizakalo zokugcina zihlele amabrandi abo. Izingxenye eziphambili zokugcina ziyizinto ezilandelayo:
Ukubeka isibhalo sasekhaya (isibhalo, ukupaka, amazwi okusebenza)
Isifunda esihlelwe isikhumbuzo esithile.
Umbala wokubuka kwezindawo noma izinhlobo zezinqamuzi.
Ukuhlanganiswa kwe-platform yokubhabha kwe-monitoring.
Ukuchaza kwezinsizakalo ngaphandle kwezinsizakalo kuyisidingo esikhulu. Abathengi be-B2B kufanele bahlale bakhokhola:
Izimvo zokuvimbela (izimvo zokuqala zokuvimbela ziyizimvo zeminyaka engu-5–10, izimvo zokuvimbela eziningi ziyatholakala)
Ukutholakala kwezinto zokulandela nokuthola kwezinsizakalo
Ukufunda kwezinto zezobuchwepheshe kubasebenzi bokufaka kwezindawo zomkhakha
Amagumbi okugcina amathuba kwezindawo zomkhakha noma amasentha wezixhumano zomkhakha
Umsebenzi wokuqala wokubuyisa izinkampani ezihlukileyo
Abahleli abanemigangatho yezobuchwepheshe nezobuchwepheshe zomkhakha ngokwesibonelo, njengoba kubhekwa kuShenzhen Weitu Hongda Industrial Co., Ltd., bangakhuthaza ukuthenga kwezinto zokuhlela ngokushesha futhi bangakhuthaza ukusiza kwezobuchwepheshe ngokushesha. Ukusiza kwezindawo zomkhakha ngokuphakathi nokusiza kwezindlela zokujabulisa ngokuphakathi kuzokwenza umphakathi wokubuyela kwezindawo zomkhakha zokuphakathi kwezindawo zomkhakha zokuphakathi kwezindawo zomkhakha zokuphakathi kwezindawo zomkhakha zokuphakathi kwezindawo zomkhakha zokuphakathi kwezindawo zomkhakha zokuphakathi kwezindawo zomkhakha zokuphakathi kwezindawo zomkhakha zokuphakathi kwezindawo zomkhakha zokuphakathi kwezindawo zomkhakha zokuphakathi kwezindawo zomkhakha zokuphakathi kwezindawo zomkhakha zokuphakathi kwezindawo zomkhakha zokuphakathi kwezindawo zomkhakha zokuphakathi kwezindawo zomkhakha zokuphakathi kwezindawo zomkhakha zokuphakathi kwezindawo zomkhakha zokuphakathi kwezindawo zomkhakha zokuphakathi kwezindawo zomkhakha zokuphakathi kwezindawo zomkhakha zokuphakathi kwezindawo zomkhakha zokuphakathi kwezindawo zomkhakha zokuphakathi kwezindawo zomkhakha zokuphakathi kwezindawo zomkhakha zokuphakathi kwezindawo zomkhakha zokuphakathi kwezindawo zomkhakha zokuphakathi kwezindawo zomkhakha zokuphakathi kwezindawo zomkhakha zokuphakathi kwezindawo zomkhakha zokuphakathi kwezindawo zomkhakha zokuphakathi kwezindawo zomkhakha zokup......
Isiphetho
Abakhasi base-B2B kufanele bahlale bavumelane nezinhlelo zokugcina izinhlelo zokuguqula ezihlanganisiwe (isilinganiso sesifunda, isikhundla se-MPPT, ukuthi kuyasebenza ngamabhatthiri), ukuthi kubhalwe ngokuphelele ukuthi kuyasebenza ngokuphelele kwe-grid emazweni abafuna ukusebenza kuzo, nokuthi kubhekwe ngokulinganisa ngokwesibonelo noma ngokwesibonelo esingaphansi kwesibonelo (OEM/ODM) ngezindlela zokusebenza emuva kokuthengiswa. Ngokubhalwa ngokuphelele kwe-ISO ne-CE, inkundla yezinye zezindaba zokuvumela ukuthi kusenziwe amathuba okuvumela ukuthi kusenziwe amathuba okuvumela ukuthi kusenziwe amathuba okuvumela ukuthi kusenziwe amathuba okuvumela ukuthi kusenziwe amathuba okuvumela ukuthi kusenziwe amathuba okuvumela ukuthi kusenziwe amathuba okuvumela ukuthi kusenziwe amathuba okuvumela ukuthi kusenziwe amathuba okuvumela ukuthi kusenziwe amathuba okuvumela ukuthi kusenziwe amathuba okuvumela ukuthi kusenziwe amathuba okuvumela ukuthi kusenziwe amathuba okuvumela ukuthi kusenziwe amathuba okuvumela ukuthi kusenziwe amathuba okuvumela ukuthi kusenziwe amathuba okuvumela ukuthi kusenziwe amathuba okuvumela ukuthi kusenziwe amathuba okuvumela ukuthi kusenziwe amathuba okuvumela ukuthi kusenziwe amathuba okuvumela ukuthi kusenziwe amathuba okuvumela ukuthi kusenziwe amathuba okuvumela ukuthi kusenziwe amathuba okuvumela ukuthi kusenziwe amathuba okuvumela ukuthi kusenziwe amathuba okuvumela ukuthi kusenziwe amathuba okuvumela ukuthi kusenziwe amathuba okuvumela ukuthi kusenziwe amathuba okuvumela ukuthi kusenziwe amathuba okuvumela ukuthi kusenziwe amathuba okuvumela ukuthi kusenziwe amathuba okuvumela ukuthi kusenziwe amathuba okuvumela ukuthi kusenziwe amathuba okuvumela ukuthi kusenziwe amathuba okuvumela ukuthi kusenziwe amathuba......
