Ndingati kuita kuti hupenyu huve nyore kune avo vasiri tekinoroji vane DC iwe ungangogara navo kana kutsigira yakanakisa sarudzo iripo nhasi ingangove USB powered ... kunyangwe ini ndichivenga nekuti magetsi emagetsi pamusoro pe USB itsvina, kuiwana zvakanaka. inoita senge idambudziko rakakura, uye haigone kuita senge njanji ye48V. Yakazara kwese zvekuti inonzwisisika kune vasiri tekinoroji - nekuti inobatika uye inoshanda (kana yakagadziriswa nemazvo). Bvisa kukosha kwekutsvaga iyo chaiyo DC-DC inoshandura kune zvese kana kunyatso tarisa "simba rekupa" voltage pese paunobaya mudziyo mutsva - ndinoita izvi padhesiki rangu asi handisati ndagocha chero chinhu ...
Asi senge yabva pasherufu bhatiri paki ine solar yekutevera yekupinza, pamwe senge inverter yeAC pack yaunofanirwa kuve nayo, uye kana iwe uchida kudzivirira kuvaka yako inoshungurudza USB magetsi, unogona kushandisa USB simba rekutaurirana chinhu. . Hazvina kunyanya kuoma kuti iwe ugadzire. Zvakare, zvinopfuura zvakakwana kuti matsotsi ari pakati pedu aise solar panels (zvichida pamamoti ekutsvagisa zuva), kupa vatariri vemamiriro, chenjedzo yebhatiri shoma, uye kuronga zvakanaka tambo munzvimbo imwechete yakakosha yebasa rehutsotsi. Zvishoma…
Mhinduro yakanaka yesimba rakawandisa ndeyekukanda mitoro yakadai semagetsi mumudziyo wemvura. Kana bhatiri razara, rinogona kushandura kushandisa simba rezuva rinowanikwa kupisa mvura.
Kunyange zvazvo mvura inopisa inogonawo "kuzadza" (inopisa zvakakwana) nekufamba kwenguva, kunze kwekuti yakakura kwazvo.
Chakanakira simba rezuva ndechekuti haufanirwe kuunganidza simba rezuva. Iwe unogona kuisa zvakachengeteka mapaneru pasi pemwaranzi yezuva pasina kushandisa simba ringangoita.
Ehezve, uku kuparara, uye kana zviri kukunakira, kudyisa simba kune grid ndiyo yekutanga sarudzo.
Sekutaura kunoita CityZen, ichazadza nekufamba kwenguva, ingori imwe nzira yekuchengetedza simba. Tisingatauri, kana iwe uchitogara munzvimbo inopisa, air conditioner yako ichashanda nesimba kana uinayo, uye kana zvisina kudaro, hupenyu hwako hunenge husingafadzi kupfuura zvahunofanira kuva, nokuti tangi yakavharidzirwa saizvozvo ... chitoro chemagetsi chakanakisa, asi dzimba zhinji hadzidi mvura inopisa yakawanda kudaro, uye tangi imwe hombe yekuseta zvinoreva kuti kana usina simba remahara, uchine mvura yakawanda yekushandisa zvizere. yakakwirira yekudziya nekuda kwenzvimbo yakakura yainokonzera.
Ikoko hakuna kunaka "kubvisa" pachiyero chega, network yakakura ine zvirimwa zvakakura zvinogona kumhanya zvishoma zvishoma uye kuwedzera kugadzirwa kupfuura kudiwa kuti iite zvakanyanya "yemahara" simba. Asi pachangu, ingori pembedzo yekutamba zvine ruzha uye dombo 24/7, kushandisa zvisina hanya simba richiripo kana kusvika muvakidzani akuuraya.
Nekudaro, mukudziya kusvika kunopisa mamiriro ekunze, kunyura kutonhora kunogona kubatsira kushandisa kupisa kwakanyanya kutonhora dzimba.
Iwe unogona zvakare kumhanyisa kamuri diki air conditioner ine inverter kana uine rakawandisa simba rekudzima uye kuchipisa. Pamwe inverter iri kunze… Zvingave zvinonakidza kuona kana uchikwanisa kugadzira pombi yekupisa inoshandisa mweya wekunze sechinhu chekupisa/radiator. Chokwadi, hazvina kunyatsoshanda, asi kana dambudziko rako rakawandisa simba, kusaita basa kunenge kwabatsira.
@smellsofbikes Nekuda kwekuti iwe dzimwe nguva une simba rakawandisa uye unogona kuvaka chimwe chinhu zvisina basa hazvireve kuti unofanirwa. Chii chinoitika kana iwe uine simba shoma izvozvi asi uchiri kufanira kupinda nenzira isinganyatso shanda? Kufanana nemuenzaniso wangu mukuru wetangi remvura uri pamusoro, unofanira kuwana mwero wakafanira kuitira kuti kana wava nesimba shoma uye kana wava nesimba rakakwana rekonzati yeheavy metal, zvakakosha/zvinobatsira zvinogona kupedzwa… . ..
Pausingakwanise kupa mari kana wadii kupa mahara **? Ipapo zvese zvakawandisa zvaunogona kugadzira ingori mukana wausiri kushandisa, uye hausi kuguma kwenyika, kunyara chete.

Vanokubhadharira mari yakawandisa – kwete kuti ndinopokana nekupa zvakawandisa, zvinoshanda kune vamwe vanhu vari muhombe network iyi uye handizvide. Asi kubhadhara kambani iyo yakawanda kune rombo rekuita mari yakawanda kubva kune vamwe vanhu…
Sezvo USB powered zvishandiso zvawanda, ndakafunga chimwe chinhu chakafanana che5V. Kunyangwe zvirinani zvingave akawanda 5V USB C ports uye akawanda AC ports. Kubva ipapo, unogona kushandisa 5V yemidziyo yemagetsi yakaderera uye USB C yemagetsi emagetsi. Iyo yakashata ndeyekuti USB C ports inofanirwa kubata voltage pachiteshi nepo USB A 5v ingori njanji ye5v.
Zvirinani, ndine chokwadi chekuti ndichapedzisira ndavaka hofisi ine 5V USB powered mains. Ndingangoita 12V futi, semapurojekiti angu emagetsi anoda anopfuura 5V anenge anogara achida 12V. (Zvakare, ndine chokwadi chekuti router yese yandinayo inoshandisa 12V, uye zvingave zvakanaka kuve neakapfava ega ega ega ega mudziyo pachinzvimbo chekushandura madziro!)
Ndine hurombo kukuudza kuti 5V (kana kunyange 12V) yakashata pakugovera magetsi: mita imwe chete kana mbiri yekukweva tambo ine kurasikirwa kwe10% kana kupfuura haigoneke. Mota dzinonetsa ne 12v nguva dzese, asi sezvo dziri diki dzinogona kuzvibata, asi marori nemabhoti mahombe anoshandisa 24v, saka hongu, 48v ndiyo yakanyanya kukosha: ichiri yakachengeteka chiyero chero iwe usingainanzva. . standard voltage, midziyo yakakwana uye kugona kutakura humwe hurefu pasina kurasikirwa kwakawanda.
Simba rekushandura kurasikirwa kwakakosha kudarika kurasikirwa kwetambo. Semuenzaniso, panyaya yechinyorwa chino, tichifunga kuti imwe neimwe DC-ku-DC shanduko inobudirira 90%, tinopedzisira tarasikirwa ne27% yesimba ratinowana kubva ku5V USB charger. Kana iyo inoshandura ichinyanya kuipa, ne85%, ipapo kurasikirwa kuchasvika 39%. Machaja ma controller uye maconverter mukuita anowanzo kwanisa kusvika 80% kunyatsoshanda, saka hazvishamisi kurasikirwa nehafu yesimba nekuda kweiyo voltage regulation. Kana iyo system inoda yakadzikira, kurasikirwa kwemidziyo isina basa kunogona kupedza rinenge simba rese.
Kunze kwekunge iwe uri kushandisa tambo dzakakora, kurasikirwa kwetambo kunogona kunge kwakakwira pa5V, uye iwe ungangozoshandisa yakawanda pane iwo tambo kupfuura iwe waungaite 24V shanduko inoshanda.
Kana iwe uine gumi nemaviri 5W USB ports, unoda 120W magetsi. Dai magetsi aigara aine 10W, zita rekuti "kugona" pamutoro wakatarwa kwaizove 92%, asi kana avhareji kushandiswa kwechiteshi che USB kunenge 5%, iyo yese chaiyo system inoshanda ingangoita 60%. .
Chero chipi zvacho chiri pasi pehudiki hwakakwana hwe36V hachifanirwe kushandiswa pamadaro marefu. Kunyanya kwete 5v. Ma adapter emagetsi akachipa, mhangura inodhura uye inorema. Mabhatiri anodhurawo uye kurasikirwa kwemagetsi idambudziko.
Ini pachangu, ini handingaite chero mhando yeLVDC microgrid zvachose (Ndaigara ndichitamba nayo uye ndaivenga zvakanyanya ndakaita vhidhiyo yakazara nezvayo).
Ndinogara ndichiti isa bhatiri panzvimbo yekutakura uye shandisa tambo yekuwedzera kana uchida simba. Kunze kwePoE, iyo inenge yemahara yeEthernet uye unogona kuida kune zvimwe zvinangwa.
USB-C yemapurojekiti ako ese, anofambiswa nemabhatiri ekunze uye maadapter emadziro sezvinodiwa. Ziva kuti USB-PD trigger modules iripo, unogona kuwana 9, 15 kana 20 kana uchida (12V haichashandi uye pamwe haishande nemaadapter matsva IIRC)
Kana iwe uchida kushandisa simba rezuva, 12V yakanaka kune diki inomhanya kusvika ku100W kwemafiti mashoma, uye zvakare yakawanda kupfuura 5V uye 48V nezvimwe, enda nazvo. Kana kungotenga yekushambadzira LifePO4 solar jenareta, iwo akanakisa.
Wese anoshuvira kuita-iwe-wega anogara achida kuita chimwe chinhu nebhazi reDC, asi kazhinji chinhu chakashata nekuti zvishandiso zvevatengi hazvina kugadzirirwa izvo uye unorasikirwa ne "zvinongoita" chikamu che USB wart inopera kwese. nzvimbo. Iwo tambo dzakakura uye boka rezvisina-standard zvinobatanidza izvo zvisingaenderane nenyika yese uye zvinongori dambudziko kune yako DIY system.
Kuitwa kwakanakisa kwandakaona ndiyo chiyero cheARES che ham radio, asi kunyangwe ipapo… zvakangonakira kumhanya mapfupi.
Kune simba re5V muhofisi, ndinongoshandisa dura remadziro rine yakavakirwa-mukati transformer uye USB port.
Kune 12V yemarouter nezvimwe zvinhu kuti zvijeke, ndaingotenga hombe 12V 5A transformer uye 2.1mm Y-cable (ita shuwa kuti unowana dzakadzikama) kana kumirira kusvika iyo trigger module iripo PPS ye12V, tora 12V. USB kubva kumidziyo mitsva - port C.
Kana zvirinani zvakadaro, bvisa kunze kwesimba re-USB pese pazvinogoneka. Kushandisa zvishoma pakuvandudza kuti uwane ese USB-PDs inogadzirisa dambudziko rese kana iwe uchida router nyowani kana chero yepamusoro-yekupedzisira router inogona kunge iri USB powered.
Kana ini ndainyatsoda 12V yekubuda, ndaizofunga kuisa Mean Well wired transformer mubhokisi rebasa riri padyo nekubuda panzvimbo pekushandisa chaizvo 12V. Hapana imwe poindi yekutadza, kurasikirwa kwesimba mune gobvu kana nhete tambo, nyore uye pachena kugadzirisa.
120V DC yakanaka kupa simba akawanda "AC" masosi, asi ndiyo yakaderera muganho wezvavanofara nazvo. Vanoda 160VDC kana kupfuura.
Aiwa, mune yangu ruzivo vakacheka zvakatenderedza 65Vdc, asi iwe unofanirwawo kuderera pazasi 130Vdc, ini handina kuyera, asi ndiri kufungidzira 100-0% mutsara kudonha kubva ku130-65Vdc.
Kufungidzira kunoshamisa. Ndiri kufungidzira kuti dunhu rekupinza riri kubata imwe yakagadziriswa ikozvino. Izvi zvinoreva kuti kana magetsi asvika 130V kusvika 65V, chiyero chinoderedzwa kusvika 50%, uye pasi pe65V, imwezve imwe voltage blocking circuit inotanga.
Mazhinji ma substations ane bhatiri rinopa simba relay dzekuchengetedza uye rinobvumira mabreaker edunhu kuti ashande (akavhurika uye achichaja) muchiitiko chekudzima kwemagetsi. Iyo yakajairika voltage ndeye 115 VDC. Inomhanya 100% pabhatiri uye ine AC-> DC charger kuti ive nechokwadi chekuti bhatiri rinogara rakazara, saka hapana solar mune iyi kesi.

Dambudziko rekugovera simba reDC rakagadziriswa nerubatsiro rwe802.3af (aka PoE) - Simba pamusoro peEthernet. Iko chaiko hakuna chikonzero chekushandisa iyo Ethernet chikamu cheiyo equation. Ubiquitous adapters, yakachengeteka simba rekugovera uye yakanakisa yekushuma / manejimendi maturusi. Hazvina kana kudhura - unogona kuwana 100Mbps 48-port data center level hub nemari shoma se £30.
The Marcel Hotel muNew Haven ine makamuri zana nemakumi matanhatu nemana, ese anofambiswa ne solar newaya DC simba. Heino mhedziso yakanaka: https://www.youtube.com/watch?v=J4aTcU6Fzoc.
Ini ndaizozvitaura, ivo vanoshandisa POE. Iko kurasikirwa kunokonzerwa nekushanda kunofanirwa kuve kushoma pane kurasikirwa kana uchichinja kubva kuDC kuenda kuAC uye kudzokera kuDC. Zvakare inokupa yakavakirwa-mukati analytics nezve zvauri kushandisa.
Dzimwe nguva ndinokanganwa kuti ndinogara kunze kwenyika. Ndine 48VDC kusvika 220VAC inverter mukuseta kwangu iyo inoisa kunze kwe5kW nguva dzose, kunyangwe isina kumbobvira yaremerwa. Pombi yemvura 220 volt, firiji, firiza, midziyo, maturusi, mwenje, zvese izvi zvakajairwa machakwi. Ndine yakaparadzana 12V uye 24V DC uye/kana mamwe marudzi mazhinji emagetsi marongero. Ita bhizinesi rekugadzira simbi munzvimbo imwechete uye pombi mvura yekunwa yebhiza guru. Mabhatiri acho anobva kuUPS system yakakura yandinowana pandinochinja mabhatiri pahurongwa. Ita bvunzo yemagetsi pamabhatiri, sarudza iwo akanakisa, wobva waisa heater yekupikisa, zvakare uchitarisa voltage, sarudza zvakanakisa zvakare uye uzvitenge.
Ehe, michina mizhinji ine "universal" AC yekupinda inogona kumhanya paDC simba. Wanza magetsi ekuisa AC ne1.4 kuti uwane yakaenzana DC voltage. Nekudaro, mafizi avo emukati haana DC akayerwa. Vatsive nefiyuzi yeDC kana kushandisa fuse yekunze. Usapisa imba!
