Taw qhia: Vim li cas Zero-Export Ua Raws Li Qhov Teeb Meem
Nrog rau kev loj hlob sai ntawm cov hnub ci xa tawm, ntau cov khoom siv hluav taws xob hauv Europe, North America, thiab Asia tau tswj hwmxoom-export (anti-reverse) txoj cai. Qhov ntawd txhais tau hais tias PV systems tsis tuaj yeem pub ntau lub zog rov qab rau hauv daim phiaj. RauEPCs, system integrators, thiab developers, qhov kev xav tau no ntxiv qhov nyuaj tshiab rau qhov project tsim.
Raws li tus thawj cojntse hwj chim meter manufacturers, OWONmuab ib tug ua tiav portfolio ntawmbidirectionalWi-Fi thiab DIN-rail zog ntsuasuas ua lub hauv paus rau kev ntseeg tauxoom-export (anti-reverse) PV kev daws teeb meem.
OWON Lub Luag Haujlwm hauv Zero-Export PV Projects
OWON lub ntsuas ntsuas ntse (xws li PC321, PC472, PC473, PC341, thiab CB432 relay meter) muab:
-
Kev ntsuas bidirectional: Muaj tseeb pom ob qho tib si ntshuam thiab xa tawm lub zog.
-
Flexible CT ranges: Los ntawm 20A txog 750A, npog thaj chaw rau cov khoom lag luam.
-
Ntau interfaces: RS485 (Modbus), RS232, MQTT, API hauv zos, huab API.
-
Local + tej thaj chaw deb kev koom ua ke: Ua hauj lwm nrog inverters, rooj vag, thiab load controllers.
Cov yam ntxwv no ua rau OWON meters zoo tagnrho rau kev sivanti-reverse hwj chim tswj, kom ntseeg tau tias kev ua raws cai thaum ua kom tus kheej siv tau ntau tshaj plaws.
System Architectures rau Zero-Export
1. Fais fab txwv ntawm Inverter tswj
-
Ntws: OWON meter → RS485 / MQTT → Inverter → Tso zis txwv.
-
Siv li cas: Chaw nyob lossis kev lag luam me me (<100 kW).
-
Tau txais txiaj ntsig: Tus nqi qis, yooj yim xaim, teb ceev ceev.
2. Load Consumption lossis Storage Integration
-
Ntws: OWON meter → Gateway / Controller → Relay (CB432) lossis Roj Teeb PCS → Siv lub zog ntxiv.
-
Siv li cas: Kev lag luam / kev lag luam tej yaam num nrog fluctuating loads.
-
Tau txais txiaj ntsig: Tiv thaiv kev thim rov qab thaum nce tus kheej noj.
Phau Ntawv Qhia Kev Xaiv Khoom
| Scenario | Pom zoo Meter | CT Range | Interface | Tshwj xeeb Feature |
|---|---|---|---|---|
| Qhov chaw nyob (≤63A) | PC472 DIN-Rail | 20–750 IB | Tuya/MQTT | Built-in 16A relay rau kev txiav tawm hauv zos |
| Split-theem (North America) | PC321 | 80-750 A | RS485/MQTT | Txhawb 120/240V split-theem |
| Kev Lag Luam / Kev Lag Luam (≤750A) | PC473 DIN-Rail | 20–750 IB | RS485/MQTT | Built-in qhuav tiv tauj tso zis |
| Ntau lub vaj tse | pc341 ua | 16 channels | RS485/MQTT | Centralized zog & xoom-export xyuas |
| Local Load Shedding | CB432 Relay Meter | 63 A | ZigBee/Wi-Fi | Txiav nyob rau hauv pob tseg load thaum rov qab zog kuaj pom |
Case Study: Hotel Chain Deployment
Lub tsev so nyob sab Europe tau teeb tsa OWON ntse ntsuas nrog inverter kev koom ua ke.
-
Kev sib tw: Kev siv hluav taws xob txwv tsis pub xa tawm vim qhov hloov pauv hloov pauv.
-
Kev daws: PC473 meters pub Modbus cov ntaub ntawv rau inverters.
-
Kev tshwm sim: 100% ua raws li xoom-export cov cai, thaum cov nqi hluav taws xob txo qis los ntawm 15% los ntawm kev ua kom zoo rau tus kheej noj.
Cov Neeg Yuav Khoom Qhia rau EPCs thiab Distributors
| Kev ntsuas ntsuas | Vim Li Cas Nws Tseem Ceeb | OWON Advantage |
|---|---|---|
| Kev ntsuas kev taw qhia | Tshawb xyuas ntshuam/export kom meej | Bidirectional metering |
| Kev them nyiaj yug raws tu qauv | Xyuas kom inverter / EMS kev koom ua ke | RS485, MQTT, API |

| Kev nyab xeeb & kev ntseeg siab | Tsis txhob poob sijhawm | Relay txiav tawm & tiv thaiv overload |
| Scalability | Haum ib leeg & multi-inverter tej yaam num | PC321 rau PC341 portfolio |
FAQ
Q1: Lub ntsuas ntsuas ntse ib leeg puas tuaj yeem tiv thaiv rov qab fais fab ntws?
Tsis yog. Qhov ntsuas ntsuas thiab cov lus ceeb toom ntws kev taw qhia. Lub inverter lossis relay system executes xoom-export tswj.
Q2: Yuav ua li cas yog tias internet poob?
OWON txhawb nqa Modbus hauv zos thiab API logic, ua kom cov inverters txuas ntxiv tau txais cov ntaub ntawv rau xoom-export ua raws.
Q3: Puas yog OWON txhawb North American cais-theem?
Yog lawm. PC321 yog tsim rau 120/240V split-theem.
Q4: Yuav ua li cas txog kev lag luam loj?
PC341 multi-circuit meter muab ceg-theem saib xyuas nrog mus txog 16 circuits, haum rau cov nroj tsuag muaj.
