I-Victron Energy Meter EM540 - 3 isigaba - max 65A/isigaba

Amamitha Amandla adlala indima ebalulekile Ezinhlelweni Zokugcina Amandla, esebenza ukukala amandla namandla kulo lonke uhlelo lokusebenza ebhokisini lokusabalalisa. Lo msebenzi ubalulekile ekuthuthukiseni ukusetshenziswa kwamandla ngokunciphisa inani lamandla angenisiwe esuka noma athunyelwe kugridi. Ukwengeza, lawa mamitha ayakwazi ukukala okukhiphayo okuvela kuma-inverter e-PV noma imithwalo ye-AC, enekhono lokubonisa le datha kumadivayisi e-GX afana ne-Cerbo GX noma i-Ekrano GX, kanye naku-VRM Portal.

I-Victron inikeza uhla lwamamodeli we-Energy Meter ukuze ivumelane nezidingo ezahlukahlukene:

• I-Victron VM-3P75CT Energy Meter: Le modeli yakhelwe amasistimu ezigaba ezintathu futhi ixhuma nge-Ethernet ne-VE.Can. Iza nama-Current Transformers (CTs) anikeziwe futhi isekela ubuningi obungama-80A ngesigaba ngasinye.
• I-ET112 Energy Meter: Ifanele izinhlelo zesigaba esisodwa ezinomthamo omkhulu we-100A, le modeli isebenzisa uxhumano lwe-RS485.
• I-ET340 Energy Meter: Lena imitha yezigaba ezintathu enoxhumo lwe-RS485, esekela ubuningi obungu-65A ngesigaba ngasinye.
• I-EM24 Ethernet Energy Meter: Kuzinhlelo zezigaba ezintathu, le mitha inikeza uxhumano lwe-Ethernet futhi ingakwazi ukuphatha kufika ku-65A ngesigaba ngasinye.
• I-EM540 Energy Meter: Enye inketho yezinhlelo zezigaba ezintathu, i-EM540 ixhuma nge-RS485 futhi isekela kufika ku-65A ngesigaba ngasinye.

Ngayinye yalawa mamodeli yakhelwe ukuthi ihlangabezane nezidingo ezithile, iqinisekisa ukuthi abasebenzisi bangathola i-Victron Energy Meter ehambisana nezidingo zokugcinwa kwamandla noma isistimu yokuqapha.

I-Venus OS isekela ububanzi obuhlukahlukene bamamitha wamandla, okuhlanganisa amamodeli akhiqizwe noma ahlinzekwa yi-Victron kanye namayunithi avela kwabanye abakhiqizi abafana noCarlo Gavazzi noma i-ABB. Lawa mamitha wamandla ayizingxenye ezibalulekile zezinhlelo ezisebenzisa idivayisi ye-GX, enza kube lula ukukalwa okunembile kokuphumayo okuvela ku-PV Inverters, i-AC Gensets, noma esebenza njenge-Grid Meter ngaphakathi Kwesistimu Yokugcina Amandla (ESS). Ukwengeza, bangakwazi ukuqapha imithwalo ye-AC, banikeze izixazululo ezibanzi zokuphatha amandla.
Uxhumano Nokucushwa:

• Imitha yamandla ye-VM-3P75CT inikezela ngoxhumano olungenamthungo kumadivayisi e-GX nge-VE.Can noma i-Ethernet, engadingi ukulungiselelwa ukuze isetshenziswe ngokushesha.
• Imitha ye-EM24 Ethernet , lapho ixhunywe kunethiwekhi yendawo efinyeleleka idivayisi ye-GX, isebenza njengenye inketho yokuxhuma nokudlala.
• Amanye amamitha wamandla axhumeka kumadivayisi e-GX nge-RS485, ngokusebenzisa i-RS485 enentambo kusixhumi esibonakalayo se-USB noma ngokungenantambo nge-Zigbee ukuya ku-USB kanye ne-Zigbee kuya kuziguquli ze-RS485, okuvumela idatha yawo ukuthi iboniswe kumadivayisi e-GX nakuphothali ye-VRM.

Imibandela Yokukhetha: Ukukhethwa kwemitha yamandla kuncike ezimfuneko zesigaba sokufakwa kanye nenani eliphezulu lamanje ngesigaba ngasinye:

• Ngoxhumo olusebenzisa izigaba ezintathu noma ama-PV Inverters, imitha yezigaba ezintathu iyadingeka.
• Izixhumanisi zesigaba esisodwa zingasebenzisa imitha yesigaba esisodwa, namamitha amaningi ezigaba ezintathu futhi akwazi ukusebenza ngemodi yesigaba esisodwa.
• Ukufakwa okudinga ukulinganiswa kokuxhumeka kwesigaba esisodwa kanye ne-PV Inverter kungakhetha amamitha amabili we-ET112 noma i-ET340.
• Izinhlelo zokusebenza ezeqa umkhawulo wesilinganiso samanje zidinga Imitha Yamandla efakwe ama-transformer amanje.

Ukukhetha Imodeli Ngokusekelwe Ezimfuneko:

• Ukufakwa kwesigaba esisodwa kufika ku-100A kungasebenzisa izixazululo zokulinganisa eziqondile/shunt njengochungechunge lwe-ET1XX/EM1XX noma i-ABB B21.
• Amasistimu ezigaba ezintathu afika ku-65A ngesigaba ngasinye nawo ayazuza ezindleleni eziqondile/shunt, zisebenzisa amamitha afana ne-ET340, EM24, noma i-ABB B23.
• Ngezidingo zamanje eziphakeme, izixazululo zamanje ze-transformer ziyanconywa, ne-VM-3P75CT yokusetha kwezigaba ezintathu okudlula i-65A ngesigaba ngasinye kuyisinqumo esifanele.

Izinketho Zokuxhuma: Ukutholakala kwenethiwekhi ye-Ethernet kungenza ukufakwa kube lula ngokusebenzisa imodi ye-Ethernet ye-VM-3P75CT kanye ne-EM24 Ethernet, kuqede isidingo sezintambo ze-RS485. Nokho, lokhu kuncike ekuthembekeni kwenethiwekhi. I-VE.Can inikeza inketho yokuxhumana elula nakakhulu futhi eqondile phakathi kwamadivayisi e-VM-3P75CT kanye ne-GX, ngaphandle kwesimo senethiwekhi.
Indlela Yokubala Amandla:

• Amamitha e-VM-3P75CT, EM24, EM3XX, EM5XX, kanye ne-ABB asebenzisa ukubhaliswa kwe-vector ukubala amandla, indlela ekhethwa emazweni amaningi ngenxa yokunemba nokwethembeka kwayo.
• Amanye amamitha asebenzisa ukubhaliswa kwe-arithmetic, okunomehluko wezindlela zokubala amandla ezichazwe kumanuwali we-Victron Energy Meter kulabo abadinga ulwazi olwengeziwe.

Lolu hlu olubanzi kanye nokuguquguquka ekuxhumaneni nasezindleleni zokulinganisa kuqinisekisa ukuthi kunesixazululo esifanelekile semitha yamandla cishe sanoma yiluphi uhlelo lokusebenza ngaphakathi kwe-Venus OS ecosystem.
