Chifukwa chiyani Balcony PV System Ikufunika OWON WiFi Smart Meter?

Balcony PV(Photovoltaics) mwadzidzidzi idatchuka kwambiri mu 2024-2025, ikukumana ndi kufunikira kwa msika ku Europe. Imasintha "mapanelo awiri + microinverter imodzi + chingwe chamagetsi chimodzi" kukhala "chomera chamagetsi chaching'ono" chomwe chimakhala ndi pulagi-ndi-sewero, ngakhale kwa anthu okhala m'nyumba wamba.

1. Nkhawa za Bili ya Mphamvu za Anthu a ku Ulaya

Mtengo wapakati wamagetsi apanyumba a EU mu 2023 unali 0.28 €/kWh, pomwe mitengo yayikulu ku Germany idakwera pamwamba pa 0.4 €/kWh. Anthu okhala m'zipinda zogonamo, opanda denga la mapanelo oyendera dzuwa, amatha kupirira ndalama zambiri za mwezi uliwonse popanda njira yopezera ndalama. Gawo la 400 Wp khonde limatha kupanga pafupifupi 460 kWh pachaka ku Munich. Kuwerengeredwa pamtengo wolemera wa 0.35 €/kWh, izi zimapulumutsa pafupifupi 160 € pachaka, zomwe zitha kudzilipira zokha m'zaka zitatu zokha - lingaliro lokongola kwambiri kwa okhala mnyumba.

Mu 2023-2024, opitilira 30 mwa zida zanyukiliya za 56 za ku France zidatsekedwa chifukwa chakuwonongeka kwamphamvu kapena kukwera kwamafuta, zomwe zidapangitsa kuti mphamvu ya nyukiliya igwe pansi pa 25 GW nthawi zina, pansi pa mphamvu ya 55 GW, kuyendetsa mwachindunji mitengo yamagetsi ku Europe. Kuyambira Januware mpaka February 2024, mphepo yamkuntho ku North Sea inali yotsika ndi 15% kuposa nthawi yomweyi, zomwe zidapangitsa kuti mphamvu ya mphepo ya Nordic ichepe ndi 20% pachaka. Mitengo yogwiritsira ntchito mphamvu yamphepo ku Denmark ndi Northern Germany idatsika pansi pa 30%, pomwe mitengo yamsika imakumana ndi mitengo yoyipa mobwerezabwereza isanalumphe pamwamba pa 0.6 €/kWh. Lipoti la European Network of Transmission System Operators for Electricity (ENTSO-E) 2024 linanena kuti zaka zogwirira ntchito za 220 kV m'mayiko monga Germany ndi France zimadutsa zaka 35. Kuchepetsa kupezeka kwa zida kumapangitsa kuti pakhale zovuta zopatsirana pafupipafupi, zomwe zimapangitsa kuti mitengo ya intraday ichuluke mpaka 2.3 nthawi ya 2020. Izi zimapangitsa kuti ndalama zamagetsi kwa okhala m'nyumba za ku Europe zifanane ndi kukwera kopitilira muyeso.

2. Kutsika kwa Mitengo ya Zida Zatsopano Zamagetsi Kuyendetsa PV ndi Kusunga M'mabanja

Pazaka zitatu zapitazi, mtengo wa ma PV modules, ma microinverter, ndi mabatire osungira atsika ndi 40%. Mtengo wa ma module ang'onoang'ono omwe ali pansi pa 800 Wp wayandikira milingo yazinthu. Pakadali pano, njira zolumikizirana ndi pulagi-ndi-sewero lakhala losavuta kukhazikitsa, ndikuchepetsa kwambiri ndalama zotumizira makina komanso kulimbikitsa kugwiritsa ntchito kwakukulu kwa khonde la PV ndi makina osungira mphamvu.

3. Ndondomeko & Malamulo: Kuchokera Kuvomereza Mwachidziwitso Kupita Kuchilimbikitso

• Germany's Renewable Energy Act (EEG 2023) imayika mwalamulo "≤800 Wp khonde PV" ngatiStecker-Solar, osapereka chilolezo, metering, ndi chindapusa cha grid, komabe amaletsa kubwezera magetsi mu gridi ya anthu kudzera m'masoketi achinsinsi.
• China ya 2024 "Distributed PV Management Measures (Draft for Comment)" imatchula "balcony PV" ngati "kang'ono kakang'ono" koma ikunena momveka bwino kuti zitsanzo "zodzigwiritsira ntchito mokwanira" ziyenera kukhala ndi zida zotetezera mphamvu zowonongeka; apo ayi, idzatengedwa ngati kuphwanya malamulo ogwiritsira ntchito magetsi.
• France, Italy, ndi Spain akhazikitsa nthawi imodzi malo olembetsera a “plug-in PV” pomwe ogwiritsa ntchito akuyenera kudzipereka koyamba “kuchepetsa mphamvu yamagetsi” kuti ayenerere kulandira ndalama zongogwiritsa ntchito 0.10–0.15 €/kWh.

Thandizo la ndondomeko lakhala msana wa kukhazikitsidwa kwa khonde la PV, koma tcheru chiyenera kuperekedwanso kuti azitsatira malamulo oletsa kusokoneza mphamvu. Apa ndipamene ma smart mita amakhala ofunikira.

4. N'chifukwa Chiyani Balcony PV System Imafunika OWON WiFi Smart Meter?

OWON, chipangizo cha IoT Original Design Manufacturer wazaka zopitilira 20, amayang'ana kwambiri kasamalidwe ka mphamvu ndi mayankho anzeru omanga. ZakePC341 WiFi Smart Meteridapangidwira zochitika ngati khonde la PV ndipo imapereka izi:

• Zofananira Zolumikizana:Nyumba zamanyumba nthawi zambiri zimakhala zopanda mikhalidwe ya RS-485 wiring, ndipo 4G/NB-IoT imabweretsa chindapusa chapachaka. WiFi, yokhala ndi pafupifupi 100% yophimba, ndi njira yoyenera yolumikizirana yamamita anzeru pamawonekedwe a khonde la PV. PC341 imathandizira 802.11 b/g/n @ 2.4GHz WiFi yolumikizira.
• Kuthekera kofunikira kwa Anti-Reverse Power Flow:Meta imayenera kudziwa momwe mphamvu yamagetsi ikuyendera nthawi yomweyo. PC341 imathandizira kuyeza kwa mphamvu ziwiri, kuyang'anira mphamvu zomwe zimagwiritsidwa ntchito komanso zopangidwa (kuphatikiza mphamvu zochulukirapo zomwe zimabwezeredwa ku gridi). Malipoti ake a masekondi 15 aliwonse amathandiza makinawo kuyankha panthawi yake.
• Kuyika-Kothandiza:Balcony PV nthawi zambiri ndi pulojekiti yobwezeretsanso, yomwe imafuna kuti mita iwonjezedwe pamalo olumikizira gridi ya PV, nthawi zambiri mkati mwa bolodi yogawa nyumba yomwe ilipo. PC341 imathandizira kuyika khoma kapena DIN njanji. Ma CT ake akuluakulu ndi ma CT ang'onoang'ono amagwiritsa ntchito zolumikizira zomvera zamitundu itatu (3.5mm ndi 2.5mm motsatana) ndi zingwe zamamita 1, ndipo zosinthira zapakatikati zimathandizira kukhazikitsa mwachangu, kukwanira bwino mkati mwa matabwa ophatikizira kunyumba.
• Kuyeza kolondola kwa Bi-directional:Zofunikira pakuwongolera zingafunike kusintha mita akale omwe sagwirizana ndi muyeso wa mbali ziwiri. PC341 idapangidwira muyeso wa mphamvu ziwiri, kuyang'anira bwino momwe amagwiritsidwira ntchito komanso kupanga, kukwaniritsa zosowa zamakasitomala a khonde la PV. Kulondola kwa metering yake kuli mkati mwa ± 2% pa katundu> 100W.
• Mlingo wa Malipoti a Data:PC341 imapereka miyeso yeniyeni ya magetsi, zamakono, mphamvu, mphamvu yogwira ntchito, ndi mafupipafupi, ndi malipoti a nthawi zonse, kuthandizira kuwunika kusintha kwa mphamvu.
• Kuyankhulana:Kulumikizana kwa WiFi kwa PC341 kumachotsa kufunikira kowonjezera kulumikizana; kungolumikizana ndi maukonde omwe alipo opanda zingwe anyumba kumathandizira kusamutsa deta, kuchepetsa kwambiri zovuta za unsembe komanso ndalama zomanga. Izi zimathandiziranso kukulitsa dongosolo lamtsogolo. Ma microinverter ambiri omwe amagwiritsidwa ntchito pamakhonde a PV amathandiziranso kulumikizana kwa WiFi, kulola kuti mita ndi microinverter zilumikizidwe ndi netiweki ya WiFi yakunyumba.
• Kugwirizana Kwadongosolo ndi Kusinthasintha:The PC341 n'zogwirizana ndi single-gawo, split-phase (120/240VAC), ndi atatu-gawo anayi-waya (480Y/277VAC) machitidwe, kusintha kwa zosiyanasiyana magetsi chilengedwe. Itha kuyang'anira mphamvu zanyumba yonse komanso mabwalo 16 (pogwiritsa ntchito 50A sub CTs), ndikupereka kusinthasintha pakukulitsa dongosolo.
• Kudalirika ndi Chitsimikizo:PC341 imanyamula chiphaso cha CE ndipo imagwira ntchito mokhulupirika mkati mwa kutentha kwakukulu (-20 ℃ ~ +55 ℃), yoyenera malo oyika m'nyumba.

5. Mapeto: OWON WiFi Smart Meter - Chothandizira chofunikira pa Balcony PV Systems

Makina a balcony PV asandutsa makhonde ambiri okhalamo kukhala "nyumba zazing'ono zamagetsi." Mamita anzeru a WiFi ngati OWON PC341 amathandiza makinawa kuti azigwira ntchito “mogwirizana, mwanzeru, motetezeka, komanso mogwira mtima”. Imagwira ntchito zingapo zofunika kuphatikiza "kuyang'anira, kuyang'anira, ndi kulumikizana." Kuyang'ana m'tsogolo, ndi kutengeranso kwamitengo yamphamvu, kugulitsa kaboni, ndi V2G, ntchito ya mita yanzeru idzasintha kupitilira mphamvu yolimbana ndi reverse mphamvu, yomwe ingathe kukwezedwa kukhala malo oyambira kasamalidwe kamagetsi apanyumba, kupangitsa kuti ma kilowatt-ola lililonse lamagetsi obiriwira awonekere, otha kutheka, komanso okhathamiritsa, zowunikira moyo wa "zerost" wamoyo.

OWON Technology imapereka mayankho athunthu kuyambira pazinthu wamba za IoT mpaka pazida za ODM. Mzere wake wazogulitsa komanso ukadaulo waluso zitha kuthandizira makina a PV a khonde komanso kugwiritsa ntchito mphamvu zamagetsi kunyumba.
