Isingeniso: Kungani Ukuthobela Imithetho Yokuthumela Ngaphandle Okungabalulekile
Ngokukhula okusheshayo kwe-solar esabalele, izinsiza eziningi eYurophu, eNyakatho Melika nase-Asia ziyaphoqelelaimithetho yokungathumeli ngaphandle (ephikisana nokuhlehla)Lokho kusho ukuthi izinhlelo ze-PV azikwazi ukubuyisela amandla angaphezulu kugridi.Ama-EPC, abahlanganisi bezinhlelo, kanye nabathuthukisi, le mfuneko inezela ubunzima obusha ekwakhiweni kwephrojekthi.
Njengomholiumenzi wamamitha kagesi ahlakaniphile, I-OWONinikeza iphothifoliyo ephelele yeizinkomba ezimbiliAmamitha kagesi e-Wi-Fi kanye ne-DIN-railezisebenza njengesisekelo sokuthembekaizixazululo ze-PV ezingathumeli ngaphandle (ezilwa nokuphenduka).
Indima ka-OWON kumaphrojekthi e-PV angadingi ukuthunyelwa kwamanye amazwe
Amamitha ahlakaniphile e-OWON (isb., i-PC321, i-PC472, i-PC473, i-PC341, kanye ne-CB432 relay meter) ahlinzeka:
-
Ukulinganisa okuqondiswa kabili: Ithola ngokunembile kokubili amandla okungenisa kanye nokuthumela ngaphandle.
-
Amabanga e-CT aguquguqukayo: Kusukela ku-20A kuya ku-750A, okuhlanganisa imithwalo yezindlu kuya kwezimboni.
-
Izixhumi eziningi: RS485 (Modbus), RS232, MQTT, i-API yendawo, i-API yamafu.
-
Ukuhlanganiswa kwendawo + okude: Isebenza ngama-inverter, ama-gateway, kanye nezilawuli zomthwalo.
Lezi zici zenza amamitha e-OWON abe afaneleke kakhulu ekusebenziseniukulawula amandla okuphikisana nokubuyela emuva, ukuqinisekisa ukuthobela imithetho ngenkathi kuthuthukiswa ukuzisebenzisa ngokweqile.
Ukwakhiwa Kwesistimu Kokungathengwa Kwe-Zero-Export
1. Ukunciphisa Amandla Ngokulawula I-Inverter
-
Ukugeleza: Imitha ye-OWON → RS485/MQTT → I-Inverter → Ukukhipha kunqunyelwe.
-
Ikesi lokusebenzisa: Izinhlelo zokuhlala noma zezentengiselwano ezincane (<100 kW).
-
Inzuzo: Izindleko eziphansi, izintambo ezilula, impendulo esheshayo.
2. Ukusetshenziswa Komthwalo noma Ukuhlanganiswa Kwesitoreji
-
Ukugeleza: Imitha ye-OWON → Isango/Isilawuli → I-Relay (CB432) noma i-Battery PCS → Sebenzisa amandla engeziwe.
-
Ikesi lokusebenzisa: Amaphrojekthi ezentengiselwano/ezimboni anemithwalo eshintshashintshayo.
-
Inzuzo: Kuvimbela ukugeleza okuphambene ngenkathi kwandisa ukuzisebenzisa.
Umhlahlandlela Wokukhetha Umkhiqizo
| Isimo | Imitha Enconyiwe | Ibanga le-CT | Isixhumi esibonakalayo | Isici Esikhethekile |
|---|---|---|---|---|
| Indawo yokuhlala (≤63A) | Isitimela se-PC472 DIN | 20–750A | I-Tuya/MQTT | I-relay engu-16A eyakhelwe ngaphakathi yokusika kwendawo |
| Isigaba esihlukanisiwe (eNyakatho Melika) | I-PC321 | 80-750A | I-RS485/MQTT | Isekela isigaba sokuhlukaniswa esingu-120/240V |
| Ezentengiselwano/Ezezimboni (≤750A) | Isitimela se-PC473 DIN | 20–750A | I-RS485/MQTT | Umkhiqizo wokuxhumana owomile owakhelwe ngaphakathi |
| Izakhiwo Ezinezijikelezo Eziningi | I-PC341 | Iziteshi ezingu-16 | I-RS485/MQTT | Ukuqapha amandla ahlanganisiwe kanye nokungabikho kokuthumela kwamanye amazwe |
| Ukususwa Komthwalo Wendawo | Imitha Yokudlulisa ye-CB432 | 63A | I-ZigBee/i-Wi-Fi | Kuncipha umthwalo wokulahla lapho kutholwa amandla abuyela emuva |
Ucwaningo Lwesibonelo: Ukuthunyelwa Kweqoqo Lehhotela
Uchungechunge lwamahhotela aseYurophu lufake amamitha ahlakaniphile e-OWON anokuhlanganiswa kwe-inverter.
-
Inselele: Ukuthunyelwa kwegridi okuvinjelwe ngenxa yokugcwala kwe-transformer.
-
Isixazululo: Amamitha angu-PC473 adlulisela idatha ye-Modbus kuma-inverter.
-
Umphumela: Ukuthobela imithetho yokuthumela ngaphandle okungu-100%, kuyilapho izindleko zamandla zehla ngo-15% ngokusebenzisa ukuzisebenzisa kahle.
Umhlahlandlela Womthengi We-EPC Nabasabalalisi
| Izindlela Zokuhlola | Kungani Kubalulekile | Inzuzo ye-OWON |
|---|---|---|
| Isiqondiso Sokulinganisa | Thola ukungenisa/ukuthumela ngokunembile | Ukulinganisa okuqondiswayo okubili |
| Usekelo Lwephrothokholi | Qinisekisa ukuhlanganiswa kwe-inverter/EMS | I-RS485, i-MQTT, i-API |
| Ukuzivumelanisa Nezimo Komthwalo | Phatha izindawo zokuhlala kuya kwezimboni | Ukumbozwa kwe-CT okungu-20A–750A |
| Ukuphepha Nokuthembeka | Gwema isikhathi sokuphumula | Ukuvikelwa kokunqanyulwa kokudluliselwa kanye nokweqisa ngokweqile |
| Ukusabalala | Faka amaphrojekthi e-single kanye ne-multi-inverter | Iphothifoliyo ye-PC321 kuya ku-PC341 |
Imibuzo Evame Ukubuzwa
Umbuzo 1: Ingabe imitha ehlakaniphile iyodwa ingavimbela ukugeleza kwamandla okuphambene?
Cha. Imitha ilinganisa futhi ibike indlela yokugeleza. Uhlelo lwe-inverter noma lwe-relay lusebenzisa ukulawula okungadingi ukuthunyelwa kwamanye amazwe.
Umbuzo 2: Kwenzekani uma i-inthanethi ingasebenzi?
I-OWON isekela i-Modbus yendawo kanye ne-API logic, iqinisekisa ukuthi ama-inverter ayaqhubeka nokuthola idatha yokuthobela imithetho yokuthumela ngaphandle.
UMBUZO 3: Ingabe i-OWON iyasisekela isigaba sokuhlukaniswa kweNyakatho Melika?
Yebo. I-PC321 yenzelwe isigaba sokuhlukaniswa esingu-120/240V.
Umbuzo 4: Kuthiwani ngamaphrojekthi amakhulu ezentengiselwano?
Imitha ye-PC341 yamasekethe amaningi inikeza ukuqapha ezingeni legatsha ngamasekethe afinyelela ku-16, afanele izitshalo zezimboni.
Isiphetho
Kubathengi be-B2B,ukuthobela imithetho yokuthumela ngaphandle kwempahla akuyona into ongayikhetha—kuyimpoqo. Nge-OWON'samamitha kagesi ahlakaniphile, ama-EPC kanye nabahlanganisi bangakha izinhlelo ze-PV ezilwa nokuphenduka ezingabizi kakhulu nezikwaziyo ukwandiswa. Kusukela emakhaya amancane kuya ezindaweni ezinkulu zezimboni, i-OWON inikezaumgogodla wokulinganisa onokwethenjelwaukugcina amaphrojekthi akho ehambisana nemithetho futhi enenzuzo.
