Kungani Uhlelo lwe-PV lwe-Balcony Ludinga i-OWON WiFi Smart Meter?

I-PV yebhalkhoni(Photovoltaics) ngokuzumayo yathola udumo olukhulu ngo-2024-2025, ibhekene nesidingo esikhulu semakethe eYurophu. Iguqula “amaphaneli amabili + i-microinverter eyodwa + ikhebula lamandla elilodwa” libe “isitshalo samandla esincane” esixhumeka futhi sidlale, ngisho nakubantu abahlala ezindlini ezivamile.

1. Ukukhathazeka Ngomthethosivivinywa Wamandla Wezakhamuzi ZaseYurophu

Intengo kagesi yasekhaya ye-EU ngo-2023 yayingu-0.28 €/kWh, kanti amazinga aphezulu eJalimane akhuphuka ngaphezu kuka-0.4 €/kWh. Izakhamuzi zasefulethini, ezingenazo izindlela zokufinyelela ophahleni lwamaphaneli elanga endabuko, zazingakwazi ukubekezelela izikweletu zikagesi eziphezulu zanyanga zonke ngaphandle kwendlela ephumelelayo yokonga imali. Imojula yebhalkhoni engu-400 Wp ingakhiqiza cishe u-460 kWh ngonyaka eMunich. Uma ibalwa ngentengo enesisindo esingu-0.35 €/kWh, lokhu konga cishe u-160 € ngonyaka, okungenzeka ukuthi kuzikhokhela eminyakeni emithathu nje kuphela - isiphakamiso esikhangayo kakhulu kubahlali basefulethini.

Ngo-2023-2024, ama-reactor enuzi angaphezu kuka-30 kwangu-56 aseFrance avalwa ngenxa yokugqwala noma ukugcwalisa uphethiloli, okwabangela ukuthi ukukhishwa kwamandla enuzi kwehle ngaphansi kuka-25 GW ngezinye izikhathi, ngaphansi kakhulu komthamo olinganiselwe ongu-55 GW, okwanyusa ngqo amanani kagesi aqondile eYurophu. Kusukela ngoJanuwari kuya kuFebhuwari 2024, isivinini somoya esimaphakathi eNorth Sea sasiphansi cishe ngo-15% kunokujwayelekile esikhathini esifanayo, okwaholela ekwehleni cishe okungu-20% ngonyaka kokukhishwa kwamandla omoya eNordic. Amanani okusetshenziswa kwamandla omoya eDenmark naseNyakatho Jalimane ehle ngaphansi kuka-30%, kanti amanani emakethe aqondile abhekana namanani amabi ngokuphindaphindiwe ngaphambi kokweqa ngaphezu kuka-0.6 €/kWh. Umbiko we-European Network of Transmission System Operators for Electricity (ENTSO-E) 2024 ukhombisile ukuthi isilinganiso seminyaka yokusebenza yeziteshi ezincane ezingu-220 kV emazweni afana neJalimane neFrance sidlula iminyaka engu-35. Ukwehla kokutholakala kwemishini kuholela ekumisweni kokudluliselwa kwamandla kagesi endaweni, okubangela ukuguquguquka kwentengo yangaphakathi kosuku ukuthi kwande ngokuphindwe kabili kunango-2.3 kunango-2020. Lokhu kwenza izikweletu zikagesi zezakhamuzi zasefulethini zaseYurophu zifane nohambo oluhamba kancane.

2. Ukwehla Kwezindleko Zemishini Emisha Yamandla Kuholela I-PV Nokugcina Emakhaya

Eminyakeni emithathu edlule, izindleko zamamojula e-PV, ama-microinverter, namabhethri okugcina izinto ziye zehla ngokuphindaphindiwe ngaphezu kuka-40%. Intengo yamamojula amancane angaphansi kuka-800 Wp isisondele emazingeni ezimpahla. Okwamanje, izixazululo zokuxhumanisa nge-plug-and-play ziye zenza inqubo yokufaka yaba lula kakhulu, zanciphisa kakhulu izindleko zokufakwa kwesistimu futhi zakhuthaza ngokushesha ukusetshenziswa okukhulu kwe-balcony PV kanye nezinhlelo zokugcina amandla.

3. Inqubomgomo kanye Nomthethonqubo: Kusukela Ekwamukeleni Okungacacile Kuya Ekukhuthazeni

• Umthetho Wamandla Avuselelekayo waseJalimane (i-EEG 2023) ubeka ngokusemthethweni "i-PV yebhalkhoni engu-≤800 Wp" njengeI-Stecker-Solar, ikhulula ekuvunyelweni, ekulinganisweni, kanye nasezimalini zegridi, kodwa isavimbela ukufaka ugesi kugridi yomphakathi ngokusebenzisa amasokhethi azimele.
• I-“Distributed PV Management Measures (Draft for Comment)” yaseShayina ka-2024 ibala “i-balcony PV” “njengesimo esincane” kodwa isho ngokusobala ukuthi amamodeli “okusebenzisa ngokugcwele” kumele afakwe amadivayisi okuvikela ukugeleza kwamandla emuva; ngaphandle kwalokho, kuzophathwa njengokwephulwa kwemithethonqubo yokusetshenziswa kukagesi.
• IFrance, i-Italy, neSpain ziqalise ngasikhathi sinye amapulatifomu okubhalisa "ama-plug-in PV" lapho abasebenzisi kufanele baqale bazibophezele "ekugelezeni kwamandla okubuyela emuva okungeyona i-zero" ukuze bafanelekele uxhaso lokuzisebenzisa oluyi-0.10–0.15 €/kWh.

Ukusekelwa kwenqubomgomo sekuwumgogodla wokusetshenziswa kwe-PV ye-balcony, kodwa kufanele futhi kuqashelwe ukuhambisana nemithethonqubo yokugeleza kwamandla ephikisana nokubuyela emuva. Yilapho amamitha ahlakaniphile eba khona abalulekile.

4. Kungani Uhlelo lwe-PV lwe-Balcony Ludinga i-OWON WiFi Smart Meter?

I-OWON, uMkhiqizi Wokuklama Kwasekuqaleni wedivayisi ye-IoT onolwazi olungaphezu kweminyaka engama-20, igxile ekuphathweni kwamandla kanye nezixazululo zokwakha ezihlakaniphile.Imitha Ehlakaniphile ye-WiFi ye-PC341yenzelwe izimo ezifana ne-balcony PV futhi inikeza izici ezilandelayo:

• Isimo Sokuxhumana Esihambisanayo:Izakhiwo zamafulethi zivame ukungabi nemibandela yokuxhuma izintambo ze-RS-485, futhi i-4G/NB-IoT ikhokhisa imali yonyaka. I-WiFi, embozwe cishe yi-100%, iyindlela yokuxhumana efanelekile kakhulu yamamitha ahlakaniphile ezimweni ze-PV zebhalkhoni. I-PC341 isekela ukuxhumana kwe-WiFi okungu-802.11 b/g/n @ 2.4GHz.
• Amandla Okugeleza Kwamandla Okulwa Nokubuyela Emuva Okubalulekile:Imitha idinga ukubona ukuvela kokugeleza kwamandla okuphambene ngokushesha. I-PC341 isekela ukulinganiswa kwamandla okuqondiswa kabili, iqapha kokubili amandla asetshenzisiwe nakhiqizwayo (kufaka phakathi amandla amaningi adluliselwa kugridi). Umjikelezo wayo wokubika wemizuzwana eyi-15 njalo usiza uhlelo ukuthi luphendule ngesikhathi.
• Kulungele ukufakwa:I-Balcony PV ngokuvamile iyiphrojekthi yokulungisa izinto, edinga ukuthi imitha ifakwe endaweni yokuxhuma igridi ye-PV, ngokuvamile ngaphakathi kwebhodi lokusabalalisa lasekhaya elikhona. I-PC341 isekela ukufakwa kwesitimela sodonga noma se-DIN. Ama-CT ayo ayinhloko nama-sub CT asebenzisa izixhumi zomsindo ezinamapali amathathu (3.5mm kanye no-2.5mm ngokulandelana) ezinezintambo zemitha eli-1, kanti ama-transformer amanje ahlukaniswe nge-core enza kube lula ukufakwa ngokushesha, angene kahle ngaphakathi kwamabhodi okusabalalisa asekhaya amancane.
• Ukulinganisa Okunembile Okuqondene Nezinhlangothi Ezimbili:Izidingo zomthetho zingase zidinge ukuthi kushintshwe amamitha amadala angasekeli ukulinganisa okuqondiswa kabili. I-PC341 yenzelwe ngqo ukulinganisa amandla okuqondiswa kabili, iqapha ngokunembile ukusetshenziswa kanye nokukhiqizwa, ihlangabezana nezidingo zobuchwepheshe zezimo ze-PV ze-balcony. Ukunemba kwayo kokulinganisa okulinganiselwe kungaphakathi kuka-±2% wemithwalo >100W.
• Izinga Lokubika Idatha:I-PC341 inikeza izilinganiso zesikhathi sangempela ze-voltage, i-current, i-power factor, i-active power, kanye ne-frequency, ngokubika idatha njalo, okusiza ekuqapheni izinguquko zamandla.
• Amakhono Okuxhumana:Ukuxhumana kwe-WiFi kwe-PC341 kususa isidingo sokufakwa kwezintambo zokuxhumana ezengeziwe; ukuxhuma nje kunethiwekhi engenantambo yasekhaya ekhona kwenza kube lula ukudluliswa kwedatha, kunciphisa kakhulu ubunzima bokufakwa kanye nezindleko zokwakha. Lokhu futhi kusiza ukunwetshwa kohlelo esikhathini esizayo. Ama-microinverter amaningi asetshenziswa ezinhlelweni ze-PV ze-balcony nawo asekela ukuxhumana kwe-WiFi, okuvumela kokubili imitha kanye ne-microinverter ukuthi zixhumeke kunethiwekhi ye-WiFi yasekhaya.
• Ukuhambisana Kwesistimu Nokuguquguquka:I-PC341 iyahambisana nezinhlelo ze-single-phase, split-phase (120/240VAC), kanye ne-three-phase four-wire (480Y/277VAC), ezivumelana nezimo ezahlukene zikagesi. Ingaqapha amandla endlu yonke kanye nama-circuit afinyelela ku-16 ngamanye (isebenzisa ama-sub CT angu-50A), inikeza ukuguquguquka kokwandiswa kwesistimu.
• Ukuthembeka kanye nesitifiketi:I-PC341 inesitifiketi se-CE futhi isebenza ngokuthembeka ngaphakathi kwebanga lokushisa elibanzi (-20℃ ~ +55℃), elifanele izindawo zokufakwa ngaphakathi.

5. Isiphetho: I-OWON WiFi Smart Meter – Isihluthulelo Esiyinhloko Sezinhlelo ze-PV ze-Balcony

Izinhlelo ze-PV ze-balcony ziguqula izigidi zama-balcony zokuhlala zibe “izitshalo zamandla ezincane.” Imitha ehlakaniphile ye-WiFi efana ne-OWON PC341 isiza lezi zinhlelo ukuthi zisebenze ngendlela “ehambisanayo, ehlakaniphile, ephephile, futhi esebenza kahle”. Idlala izindima eziningi ezibalulekile okuhlanganisa “ukulinganisa, ukuqapha, kanye nokuxhumana.” Uma sibheka phambili, ngokusetshenziswa okwengeziwe kwentengo eguquguqukayo, ukuhweba ngekhabhoni, kanye ne-V2G, umsebenzi wemitha ehlakaniphile uzothuthuka ngale nje kokugeleza kwamandla okulwa nokuphenduka, okungenzeka uthuthuke ube yindawo ebalulekile ohlelweni lokuphathwa kwamandla ekhaya, okwenza yonke i-kilowatt-hora kagesi oluhlaza ibonakale, ilawuleke, futhi ithuthukiswe, ikhanyise ngempela “imayela lokugcina” lokuphila okungenakhabhoni.

I-OWON Technology inikeza izixazululo eziphelele kusukela emikhiqizweni ejwayelekile ye-IoT kuya kumasevisi e-ODM edivayisi. Umugqa wayo womkhiqizo kanye nobuchwepheshe bobungcweti kungasekela izinhlelo ze-PV ze-balcony kanye nezinhlelo zokusebenza ezibanzi zokuphathwa kwamandla ekhaya.
