Chiyambi: Chifukwa Chake Kutsatira Kutengera Kutumiza Kumayiko Ena Kulibe Kuli Kofunikira
Ndi kukula kwachangu kwa solar yogawidwa, zofunikira zambiri ku Europe, North America, ndi Asia zikugwira ntchitomalamulo a zero-export (anti-reverse).. Izi zikutanthauza kuti makina a PV sangathe kudyetsa mphamvu zowonjezera mu gridi. ZaEPCs, ophatikiza ma system, ndi opanga, chofunikira ichi chimawonjezera zovuta zatsopano pamapangidwe a polojekiti.
Monga wotsogolerawopanga mita wanzeru, OWONimapereka mbiri yathunthu yazapawiriWi-Fi ndi DIN-njanji mphamvu mitaamene amakhala maziko odalirikazero-export (anti-reverse) mayankho a PV.
Udindo wa OWON mu Zero-Export PV Projects
Mamita anzeru a OWON (mwachitsanzo, PC321, PC472, PC473, PC341, ndi CB432 relay mita) amapereka:
-
Muyeso wa njira ziwiri: Imazindikira bwino mphamvu zonse zolowetsa ndi kutumiza kunja.
-
Mitundu yosinthika ya CT: Kuchokera 20A mpaka 750A, kuphimba nyumba zogulitsa katundu.
-
Zolumikizira zingapo: RS485 (Modbus), RS232, MQTT, local API, cloud API.
-
Kuphatikizika kwanuko + kutali: Imagwira ntchito ndi ma inverters, zipata, ndi owongolera katundu.
Izi zimapangitsa mamita a OWON kukhala abwino kuti agwiritse ntchitoanti-reverse power control, kuonetsetsa kutsatiridwa pamene kukulitsa kudzikonda.
Zomangamanga Zadongosolo za Zero-Export
1. Kuchepetsa Mphamvu kudzera pa Inverter Control
-
Yendani: OWON mita → RS485/MQTT → Inverter → Kutulutsa kochepa.
-
Gwiritsani ntchito: Njira zogona kapena zazing'ono zamalonda (<100 kW).
-
Pindulani: Mtengo wotsika, waya wosavuta, kuyankha mwachangu.
2. Kugwiritsa Ntchito Katundu kapena Kuphatikiza Kusungirako
-
Yendani: OWON mita → Gateway/Controller → Relay (CB432) kapena Battery PCS → Gwiritsani ntchito mphamvu zowonjezera.
-
Gwiritsani ntchito: Ntchito zamalonda / zamafakitale zokhala ndi katundu wosinthasintha.
-
Pindulani: Imalepheretsa kuyenda mobwerera m'mbuyo ndikuwonjezera kudzigwiritsa ntchito.

Nkhani Yophunzira: Kutumiza kwa Chain Hotelo
Unyolo wamahotelo aku Europe adayika mita yanzeru ya OWON yokhala ndi inverter kuphatikiza.
-
Chovuta: Zogwiritsidwa ntchito ndizoletsedwa kutumiza gridi chifukwa cha kuchuluka kwa ma transfoma.
-
Yankho: PC473 mita kudyetsa Modbus deta kuti inverters.
-
Zotsatira: 100% kutsata malamulo otumiza ziro kunja, pomwe mabilu amagetsi adatsika ndi 15% chifukwa chodzigwiritsa ntchito bwino.

FAQ
Q1: Kodi mita yanzeru yokha ingalepheretse kuyenda kwamphamvu mobwerera?
Ayi. Miyezo ya mita ndi malipoti amayendedwe ake. Inverter kapena relay system imagwira ntchito zotumiza kunja kwa zero.
Q2: Chimachitika ndi chiyani ngati intaneti ikutsika?
OWON imathandizira malingaliro a Modbus am'deralo ndi API, kuwonetsetsa kuti ma inverters akupitilizabe kulandira zidziwitso zotsatiridwa ndi zero-export.
Q3: Kodi OWON imathandizira gawo logawanika la North America?
Inde. PC321 idapangidwira 120/240V gawo logawanika.
Q4: Nanga bwanji ntchito zazikulu zamalonda?
Mamita ozungulira a PC341 amapereka kuwunika kwa nthambi mpaka mabwalo 16, oyenera kumafakitale.
Mapeto
Kwa ogula B2B,kutsata ziro-kutumiza kunja sikosankha-ndikofunikira. Ndi OWONsmart magetsi mita, ma EPC ndi ophatikiza amatha kupanga makina opangira ma PV otsika mtengo komanso owopsa. Kuchokera ku nyumba zazing'ono kupita ku malo akuluakulu ogulitsa mafakitale, OWON imaperekaodalirika metering msanakuti mapulojekiti anu azikhala ogwirizana komanso opindulitsa.
