Mayankho a PV Zero-Export okhala ndi Smart Power Meters - Chifukwa Chake Ogula a B2B Amasankha OWON

Chiyambi: Chifukwa Chake Kutsatira Malamulo Osatumiza Zinthu Kuli Kofunika

Ndi kukula kwachangu kwa magetsi a dzuwa, magetsi ambiri ku Europe, North America, ndi Asia akukakamizamalamulo osatumiza zinthu kunja (otsutsana ndi kusintha)Izi zikutanthauza kuti makina a PV sangathe kubwezeretsanso mphamvu yochulukirapo mu gridi.Ma EPC, ophatikiza dongosolo, ndi opanga mapulogalamu, izi zimawonjezera zovuta zatsopano pakupanga polojekiti.

Monga mtsogoleriwopanga mita yamagetsi anzeru, OWONimapereka mbiri yonse yambali ziwiriMiyezo yamagetsi ya Wi-Fi ndi DIN-railzomwe zimakhala maziko a zodalirikaMayankho a PV osatumiza kunja (otsutsana ndi kubwerera m'mbuyo).

Udindo wa OWON mu Mapulojekiti a Zero-Export PV

Mamita anzeru a OWON (monga PC321, PC472, PC473, PC341, ndi CB432 relay meter) amapereka:

• Muyeso wa mbali ziwiri: Imazindikira molondola mphamvu yolowera ndi kutumiza kunja.

• Mitundu ya CT yosinthasintha: Kuyambira 20A mpaka 750A, zomwe zimaphatikizapo katundu wa m'nyumba mpaka mafakitale.

• Ma interfaces angapo: RS485 (Modbus), RS232, MQTT, API yakomweko, API ya mtambo.

• Kuphatikiza kwapafupi + kwakutali: Imagwira ntchito ndi ma inverter, ma gateway, ndi zowongolera katundu.

Zinthu izi zimapangitsa kuti mita ya OWON ikhale yabwino kwambiri pogwiritsira ntchitomphamvu yoletsa kubwerera m'mbuyo, kuonetsetsa kuti malamulo akutsatira malamulowo pamene akuwonjezera kugwiritsa ntchito bwino ndalama zomwe munthu akugwiritsa ntchito.

Mapangidwe a Machitidwe a Zero-Export

1. Kuchepetsa Mphamvu Kudzera mu Inverter Control

• Kuyenda: Mita ya OWON → RS485/MQTT → Inverter → Chotulutsa chochepa.

• Chogwiritsiridwa ntchito: Makina okhala kapena ang'onoang'ono amalonda (<100 kW).

• Phindu: Mtengo wotsika, mawaya osavuta, yankho lachangu.

2. Kugwiritsa Ntchito Katundu Kapena Kusunga Zinthu Zosungirako

• Kuyenda: Mita ya OWON → Chipata/Wowongolera → Relay (CB432) kapena Batri PCS → Gwiritsani ntchito mphamvu yowonjezera.

• Chogwiritsiridwa ntchito: Mapulojekiti amalonda/mafakitale okhala ndi katundu wosinthasintha.

• Phindu: Zimaletsa kuyenda kwa madzi m'thupi mobwerera m'mbuyo pamene zimawonjezera kumwa madzi okha.

Phunziro la Nkhani: Kutumizidwa kwa Mahotela Osiyanasiyana

Unyolo wa hotelo ku Ulaya unayika OWON smart meters yokhala ndi inverter integration.

• Vuto: Kutumiza kwa gridi yogwiritsidwa ntchito kwaletsedwa chifukwa cha kuchuluka kwa transformer.

• Yankho: Mamita a PC473 akupatsa deta ya Modbus ku ma inverter.

• Zotsatira: Kutsatira malamulo osatumiza kunja konse 100%, pomwe ndalama zamagetsi zinachepa ndi 15% chifukwa chodzigwiritsa ntchito bwino.

FAQ

Q1: Kodi mita yanzeru yokha ingalepheretse kuyenda kwa magetsi mobwerera m'mbuyo?
Ayi. Chiyesochi chimayesa ndikuwonetsa komwe kayendedwe ka madzi akuyendera. Makina a inverter kapena relay amagwiritsa ntchito njira yowongolera kutumiza kunja kwa dziko.

Q2: Kodi chimachitika ndi chiyani ngati intaneti yatha?
OWON imathandizira njira ya Modbus ndi API, kuonetsetsa kuti ma inverters akupitiliza kulandira deta kuti asatumize deta kunja.

Q3: Kodi OWON ikuthandizira gawo logawanika la North America?
Inde. PC321 yapangidwa kuti igwiritsidwe ntchito pa gawo logawanika la 120/240V.

Q4: Nanga bwanji za mapulojekiti akuluakulu amalonda?
Chida choyezera ma circuit ambiri cha PC341 chimapereka kuwunika kwa nthambi ndi ma circuit okwana 16, oyenera mafakitale a mafakitale.

Kwa ogula B2B,Kutsatira malamulo okhudza kutumiza katundu kunja sikofunikira—ndi kofunikiraNdi a OWONmita yamagetsi yanzeru, Ma EPC ndi ophatikiza amatha kupanga makina a PV oletsa kubwereranso m'mbuyo omwe ndi otsika mtengo komanso otheka kukula. Kuyambira nyumba zazing'ono mpaka malo akuluakulu amafakitale, OWON imaperekamsana wodalirika woyezerakuti mapulojekiti anu azitsatira malamulo komanso kuti apindule.
