Intshayelelo: Kutheni Kubalulekile Ukuthotyelwa kweMithetho yoThumelo ngaphandle
Ngokukhula ngokukhawuleza kwemithombo yelanga esasazwayo, iinkonzo ezininzi eYurophu, eMntla Melika, naseAsia ziyanyanzelisa ukubaimithetho yokuthumela ngaphandle (echasene nokubuyela umva)Oko kuthetha ukuba iinkqubo ze-PV azinakubuyisela amandla angaphezulu kwigridi.Ii-EPC, abahlanganisi beenkqubo, kunye nabaphuhlisi, le mfuneko yongeza ubunzima obutsha kuyilo lweprojekthi.
Njengomntu okhokelayoumenzi wemitha yamandla ekrelekrele, U-OWONinika ipotifoliyo epheleleyo yeicala eliya kumacala omabiniIimitha zamandla ze-Wi-Fi kunye ne-DIN-railezisebenza njengesiseko sokuthembekaizisombululo ze-PV ezingathunyelwa ngaphandle (ezichasene nokubuyela umva).
Indima ka-OWON kwiiprojekthi ze-PV ezingathunyelwa ngaphandle
Iimitha ezikrelekrele ze-OWON (umz., i-PC321, i-PC472, i-PC473, i-PC341, kunye ne-CB432 relay meter) zibonelela ngezi:
-
Ukulinganisa i-Bidirectional: Ibona ngokuchanekileyo zombini amandla okungenisa kunye nokuthumela ngaphandle.
-
Uluhlu lwe-CT oluguquguqukayo: Ukusuka kwi-20A ukuya kwi-750A, egubungela imithwalo yezindlu ukuya kwimizi-mveliso.
-
Iindawo zokujonga ezininzi: RS485 (Modbus), RS232, MQTT, API yendawo, API yelifu.
-
Ukuhlanganiswa kwendawo + okukude: Isebenza ngee-inverters, ii-gateways, kunye nezilawuli zomthwalo.
Ezi mpawu zenza iimitha ze-OWON zilungele ukusetyenziswaulawulo lwamandla oluchasene nokubuyela umva, ukuqinisekisa ukuthotyelwa kwemithetho ngelixa kusetyenziswa kakhulu ukuzisebenzisa.
Uyilo lweNkqubo yeZero-Export
1. Ukunciphisa Amandla ngoLawulo lwe-Inverter
-
Ukuhamba: Imitha ye-OWON → RS485/MQTT → I-Inverter → Isiphumo sinqunyelwe.
-
Ityala lokusetyenziswa: Iinkqubo zokuhlala okanye zorhwebo ezincinci (<100 kW).
-
Inzuzo: Ixabiso eliphantsi, intambo elula, impendulo ekhawulezayo.
2. Ukusetyenziswa koMthwalo okanye ukuHlanganisa uGcino
-
Ukuhamba: Imitha ye-OWON → Isango/uMlawuli → I-Relay (CB432) okanye ii-PCS zeBhetri → Sebenzisa amandla angaphezulu.
-
Ityala lokusetyenziswa: Iiprojekthi zorhwebo/zemizi-mveliso ezinemithwalo eguquguqukayo.
-
Inzuzo: Ithintela ukuhamba okungasemva ngelixa inyusa ukuzisebenzisa.
Isikhokelo soKhetho lweMveliso

FAQ
Q1: Ngaba imitha ekrelekrele yodwa ingathintela ukuhamba kwamandla okujika umva?
Hayi. Imitha ilinganisa kwaye inike ingxelo yecala lokuhamba kombane. Inkqubo ye-inverter okanye ye-relay isebenzisa ulawulo lokuthumela ngaphandle olungenalo.
Umbuzo 2: Kuza kwenzeka ntoni ukuba i-intanethi ayisebenzi?
I-OWON ixhasa i-Modbus yasekuhlaleni kunye ne-API logic, iqinisekisa ukuba ii-inverters ziyaqhubeka nokufumana idatha yokuthobela imithetho yokuthumela ngaphandle.
Umbuzo 3: Ngaba i-OWON iyayixhasa i-North American split-phase?
Ewe. I-PC321 yenzelwe i-120/240V split-phase.
