Nhanganyaya: Sei Zero-Export Compliance Iine Basa
Nekukurumidza kukura kwesolar yakagoverwa, zvishandiso zvakawanda muEurope, North America, uye Asia zviri kuitazero-export (anti-reverse) mitemo. Izvi zvinoreva kuti maPV masisitimu haakwanise kufudza simba rakawandisa kudzoka mugedhi. ForEPCs, system integrators, uye vanogadzira, ichi chinodiwa chinowedzera kuomarara kutsva pakugadzira purojekiti.
Somutungamiriakangwara simba mita mugadziri, OWONinopa yakakwana portfolio yebidirectionalWi-Fi uye DIN-njanji simba mitaiyo inobatira senheyo yokuvimbikazero-export (anti-reverse) PV mhinduro.
Basa reOWON muZero-Export PV Projects
OWON's smart metres (semuenzaniso, PC321, PC472, PC473, PC341, uye CB432 relay mita) inopa:
-
Bidirectional kuyerwa: Inonyatsoona zvese zvekupinza uye kunze simba.
-
Flexible CT siyana: Kubva 20A kusvika 750A, inovhara pekugara kusvika kune maindasitiri mitoro.
-
Multiple interfaces: RS485 (Modbus), RS232, MQTT, local API, cloud API.
-
Yemunharaunda + kubatanidzwa kure: Inoshanda nema inverters, magedhi, uye mutoro controllers.
Aya maficha anoita maOWON metres akanakira kuitaanti-reverse power control, kuve nechokwadi chekuteerera uku uchiwedzera kuzvidyira.
System Architectures yeZero-Export
1. Power Limiting kuburikidza neInverter Control
-
Flow: OWON mita → RS485/MQTT → Inverter → Kubuda kushoma.
-
Shandisa kesi: Zvirongwa zvekugara kana zviduku zvekutengeserana (<100 kW).
-
Benefit: Mutengo wakaderera, wiring iri nyore, mhinduro inokurumidza.
2. Mutoro Wekushandisa kana Kuchengeta Kubatanidzwa
-
Flow: OWON mita → Gedhi/Controller → Relay (CB432) kana Bhatiri PCS → Kushandisa rakawedzerwa simba.
-
Shandisa kesi: Mapurojekiti eCommerce/maindasitiri ane mitoro inochinja.
-
Benefit: Inodzivirira reverse kuyerera uchiwedzera kuzvidyira.

Nyaya Yechidzidzo: Hotel Chain Deployment
Imwe hotera yekuEurope yakaisa OWON smart metres ine inverter yekubatanidza.
-
Dambudziko: Utility inorambidzwa gidhi kunze kwenyika nekuda kwekuzara kwetransformer.
-
Solution: PC473 metres kudyisa Modbus data kune inverters.
-
Mhedzisiro: 100% kutevedzera mitemo yezero-export, nepo mabhiri emagetsi akadzikira ne15% kuburikidza nekunyatsozvishandisa.

FAQ
Q1: Ko mita yakangwara yega inogona kudzivirira reverse simba kuyerera?
Kwete. Mameta uye mishumo inoyerera mafambiro. Iyo inverter kana relay system inoita zero-export control.
Q2: Chii chinoitika kana internet ichidzika?
OWON inotsigira yemuno Modbus uye API logic, kuve nechokwadi chekuti ma inverters anoramba achigamuchira data yezero-export kutevedzera.
Q3: Ko OWON inotsigira North America kupatsanura-chikamu?
Ehe. Iyo PC321 yakagadzirirwa 120/240V kupatsanura-chikamu.
Q4: Zvakadini nemapurojekiti makuru ekutengeserana?
Iyo PC341 yakawanda-yedunhu mita inopa bazi-chikamu chekutarisa neanosvika gumi nematanhatu maseketi, akakodzera zvirimwa zveindasitiri.
Mhedziso
Kune vatengi veB2B,zero-export kutevedza haisi sarudzo-inosungirwa. NeOWON'ssmart power metres, EPCs uye vanobatanidza vanogona kuvaka inodhura-inoshanda uye scalable anti-reverse PV masisitimu. Kubva kudzimba diki kuenda kunzvimbo dzakakura dzeindasitiri, OWON inopa iyoyakavimbika metering musanakuchengetedza mapurojekiti ako achienderana uye aine pundutso.
