Selelekela: Hobaneng e le Taba ea Bohlokoa ba Tumellano ea ho Romella kantle ho naha
Ka kholo e potlakileng ea matla a letsatsi, lits'ebeletso tse ngata Europe, Amerika Leboea le Asia lia sebetsamelawana ya thomello kantle ho naha (anti-reverse).. Seo se bolela hore lits'ebetso tsa PV ha li khone ho fepa matla a feteletseng ka har'a grid. Bakeng saLi-EPC, bahokahanyi ba sistimi, le bahlahisi, tlhokahalo ena e eketsa ho rarahana ho hocha ho moralo oa morero.
E le moetapelemoetsi oa mitha ea matla a bohlale, OONAe fana ka potefolio e feletseng eabidirectionalLimithara tsa matla a Wi-Fi le DIN-railtse sebeletsang e le motheo oa ho tšepahalazero-export (anti-reverse) tharollo ea PV.
Karolo ea OWON ho Merero ea PV ea Zero-Export
Limithara tse bohlale tsa OWON (mohlala, PC321, PC472, PC473, PC341, le CB432 relay meter) li fana ka:
-
Tekanyo ea mahlakore a mabeli: E lemoha ka nepo matla a ho kenya le ho romela kantle.
-
Mekhahlelo ea CT e feto-fetohang: Ho tloha 20A ho ea ho 750A, e koahelang meroalo ea bolulo ho ea indastering.
-
Li-interfaces tse ngata: RS485 (Modbus), RS232, MQTT, API ea sebakeng seo, API ea leru.
-
Khokahano ea lehae + e hole: E sebetsa ka li-inverters, liheke, le li-control controller.
Likarolo tsena li etsa hore limithara tsa OWON e be tse loketseng ho sebelisoaanti-reverse power control, ho etsa bonnete ba ho lumellana ha ho ntse ho eketsa tšebeliso ea boipheliso.
Mehaho ea Sisteme bakeng sa Zero-Export
1. Moeli oa Matla ka Inverter Control
-
Phallang: OWON mitha → RS485/MQTT → Inverter → Output limited.
-
Sebelisa nyeoe: Mekhoa ea bolulo kapa e nyenyane ea khoebo (<100 kW).
-
Molemo: Theko e tlaase, wiring e bonolo, karabo e potlakileng.
2. Tšebeliso ea Meroalo kapa Tšebeliso ea Polokelo
-
Phallang: OWON mitha → Gateway/Controller → Relay (CB432) kapa Battery PCS → Sebelisa matla a eketsehileng.
-
Sebelisa nyeoe: Merero ea khoebo / ea indasteri e nang le meroalo e feto-fetohang.
-
Molemo: E thibela ho phalla ha morao ha u ntse u eketsa tšebeliso ea hau.

Mohlala: Ho tsamaisoa ha Chain Hotel
Ketane ea lihotele tsa Europe e kentse limithara tse bohlale tsa OWON tse kopantsoeng le inverter.

Phephetso: Ts'ebeliso e thibetsoe ho romelloa kantle ho marang-rang ka lebaka la ho tlala ha motlakase.
-
Tharollo: Limithara tsa PC473 li fepa data ea Modbus ho li-inverters.

Q1: Na mitha e bohlale feela e ka thibela ho phalla ha matla a morao?
Che. Methapo e metha le tataiso ea phallo ea litlaleho. Sistimi ea inverter kapa relay e etsa taolo ea kantle ho zero.
Q2: Ho etsahala'ng haeba marang-rang a theoha?
OWON e ts'ehetsa logic ea Modbus le API ea lehae, ho netefatsa hore li-inverters li tsoela pele ho fumana data bakeng sa ho latela li-zero-export.
Q3: Na OWON e tšehetsa karolo ea Amerika Leboea?
Ee. PC321 e etselitsoe karolo ea 120/240V ea ho arohana.
Q4: Ho thoe'ng ka merero e meholo ea khoebo?
Metara e nang le li-circuit tse ngata tsa PC341 e fana ka tlhokomelo ea lekala ka li-circuits tse fihlang ho tse 16, tse loketseng limela tsa indasteri.
