Isingeniso: Kungani Kubalulekile Ukuthobela I-Zero-Export
Ngokukhula okusheshayo kwe-solar esabalalisiwe, izinsiza eziningi eYurophu, eNyakatho Melika nase-Asia ziyaphoqelelaImithetho yokuthekelisa enguziro (anti-reverse).. Lokho kusho ukuthi amasistimu e-PV awakwazi ukondla amandla engeziwe abuyele kugridi. NgobaAma-EPC, izihlanganisi zesistimu, nabathuthukisi, le mfuneko yengeza ubunkimbinkimbi obusha ekwakhiweni kwephrojekthi.
NjengomholiUmkhiqizi wamamitha wamandla ahlakaniphile, OWONinikeza iphothifoliyo ephelele yeokuphindwe kabiliI-Wi-Fi ne-DIN-rail energy metresezisebenza njengesisekelo sokwethenjelwaizixazululo ze-PV ze-zero-export (anti-reverse)..
Iqhaza lika-OWON kokuthi Zero-Export PV Projects
Amamitha ahlakaniphile e-OWON (isb, i-PC321, i-PC472, i-PC473, i-PC341, nemitha yokudlulisela i-CB432) ahlinzeka:
-
Isilinganiso sezinhlangothi ezimbili: Ithola ngokunembile kokubili amandla okungenisa nawokuthekelisa.
-
I-Flexible CT ububanzi: Kusuka ku-20A ukuya ku-750A, okuhlanganisa indawo yokuhlala kuya kwemithwalo yezimboni.
-
Izindawo zokusebenzelana eziningi: RS485 (Modbus), RS232, MQTT, i-API yendawo, i-API yamafu.
-
Ukuhlanganiswa kwasendaweni + okukude: Isebenza ngama-inverter, amasango, nezilawuli zokulayisha.
Lezi zici zenza amamitha e-OWON alungele ukusetshenziswaukulawulwa kwamandla okuphambene nokuhlehla, ukuqinisekisa ukuthobela ngenkathi kukhulisa ukuzisebenzisa.
I-System Architectures ye-Zero-Export
1. Ukunciphisa Amandla nge-Inverter Control
-
Ukugeleza: imitha ye-OWON → RS485/MQTT → Inverter → Okukhiphayo kukhawulelwe.
-
Sebenzisa icala: Izinhlelo zokuhlala noma ezentengiselwano ezincane (<100 kW).
-
Zuza: Izindleko eziphansi, izintambo ezilula, impendulo esheshayo.
2. Ukusetshenziswa Komthwalo noma Ukuhlanganiswa Kwesitoreji
-
Ukugeleza: imitha ye-OWON → Isango/Isilawuli → I-Relay (CB432) noma I-PCS Yebhethri → Sebenzisa amandla engeziwe.
-
Sebenzisa icala: Amaphrojekthi ezohwebo/izimboni anemithwalo eguquguqukayo.
-
Zuza: Ivimbela ukugeleza okubuyela emuva ngenkathi ikhulisa ukuzidla.
Umhlahlandlela Wokukhetha Umkhiqizo
| Isimo | Imitha Enconyiwe | Ububanzi be-CT | Isixhumi esibonakalayo | Isici Esikhethekile |
|---|---|---|---|---|
| Indawo yokuhlala (≤63A) | I-PC472 DIN-Rail | 20–750A | I-Tuya/MQTT | I-relay eyakhelwe ngaphakathi engu-16A yokunqanyulwa kwendawo |
| Isigaba sokuhlukaniswa (eNyakatho Melika) | PC321 | 80-750A | RS485/MQTT | Isekela 120/240V isigaba sokuhlukaniswa |
| Ezohwebo/Ezezimboni (≤750A) | I-PC473 DIN-Rail | 20–750A | RS485/MQTT | Okwakhelwe ngaphakathi okukhiphayo koxhumana naye okomile |
| Izakhiwo ezineziyingi eziningi | PC341 | 16 iziteshi | RS485/MQTT | Amandla aphakathi nendawo nokuqapha ukuthunyelwa ngaphandle |
| Ukuchithwa Kwemithwalo Yasendaweni | I-CB432 Relay Meter | 63A | I-ZigBee/Wi-Fi | Inciphisa umthwalo wokulahla lapho amandla abuyela emuva etholwa |
Indaba eyisibonelo: Ukuthunyelwa Kochungechunge Lwehhotela
Uchungechunge lwamahhotela aseYurophu lufake amamitha ahlakaniphile e-OWON anokuhlanganiswa kwe-inverter.
-
Inselele: Ukusetshenziswa kwegridi enqatshelwe ukuthekelisa ngenxa yokugcwala kwesiguquli.
-
Isixazululo: Amamitha we-PC473 wondla idatha ye-Modbus kuma-inverters.
-
Umphumela: Ukuthobela okungu-100% kwemithetho yokuthekelisa iqanda, kuyilapho izikweletu zamandla zehle ngo-15% ngokusebenzisa ukuzisebenzisela wena okulungiselelwe.
Umhlahlandlela Womthengi wama-EPC nabasabalalisi
| Imibandela Yokuhlola | Kungani Kubalulekile? | Inzuzo ye-OWON |
|---|---|---|
| I-Measurement Direction | Thola ukungenisa/ukuthekelisa ngokunembile | I-Bidirectional metering |
| Ukusekelwa Kwephrothokholi | Qinisekisa ukuhlanganiswa kwe-inverter/EMS | RS485, MQTT, API |
| Layisha Ukuguquguquka | Phatha indawo yokuhlala kuya kwezimboni | Ukufakwa kwe-20A–750A CT |
| Ukuphepha Nokwethenjelwa | Gwema isikhathi sokuphumula | Ukunqanyulwa kwe-relay nokuvikela ukugcwala ngokweqile |
| I-Scalability | Fit single & multi-inverter amaphrojekthi | Iphothifoliyo ye-PC321 kuya ku-PC341 |
FAQ
Q1: Ingabe imitha ehlakaniphile iyodwa ingavimbela ukugeleza kwamandla ahlehlayo?
Cha. Imitha ikala futhi ibika isiqondiso sokugeleza. I-inverter noma isistimu ye-relay isebenzisa isilawuli se-zero-export.
Q2: Kwenzekani uma i-inthanethi yehla?
I-OWON isekela i-Modbus yendawo kanye ne-API logic, iqinisekisa ukuthi iziguquli ziyaqhubeka nokuthola idatha yokuthobela i-zero-export.
Q3: Ingabe i-OWON isekela isigaba sokuhlukaniswa kweNyakatho Melika?
Yebo. I-PC321 yakhelwe i-120/240V isigaba sokuhlukaniswa.
Q4: Kuthiwani ngamaphrojekthi amakhulu okuhweba?
Imitha ye-PC341 eneziyingi eziningi ihlinzeka ngokuqapha ezingeni legatsha ngamasekethe afinyelela kwayi-16, afanele izitshalo zezimboni.
Isiphetho
Kubathengi be-B2B,Ukuthobela iqanda lokuthekelisa akuyona into yokuzikhethela—kuyimpoqo. Nge-OWON'samamitha amandla ahlakaniphile, ama-EPC kanye nezihlanganisi zingakha amasistimu e-PV aphikisana nokuhlehla angabizi futhi angalawuleki. Ukusuka ezindlini ezincane kuya kumasayithi amakhulu ezimboni, i-OWON inikezaumgogodla wokulinganisa othembekileukugcina amaphrojekthi akho ethobela futhi enenzuzo.
