FAQ
Mubvunzo: Is UL 9540A chitupa chakasiyana kubva kuUL 9540?
A: Kwete. UL 9540A inzira yekuyedza-inoburitsa report ine data rekuita, kwete chitupa. Iko hakuna yakamira "UL 9540A certification," zvisinei nezvauchaona pane mamwe madhetiteti.Mayfield Renewables inotsanangura mutsauko zvakanaka: chitupa kuUL 9540 chinoda UL 9540A kuyedzwa kana zvichiratidzwa nemakodhi ako AHJ anotevera, asi hapana chakasiyana 9540A chitupa.
Mubvunzo: Inotora nguva yakareba sei UL 9540 certification?
A: Kazhinji 3 kusvika 12 mwedzi. Iwo makuru akasiyana-siyana: kuti chikamu chako-chirevo chezvitupa (UL 1973, UL 1741) chatovapo, kuti mapepa epasuru yako akakwana zvakadii, uye kuti lab yekuongorora yakatsigirwa sei. Takaona vagadziri vane ruzivo rwekare vachipfuura mukati memwedzi mina. Kutanga-nenguva ine zvisina kukwana kutumira? Kwasara gore.
Mubvunzo: Yangu sisitimu ine CE yekumaka. Ndinogona kuiisa kuUS?
A: Kwete. CE kuzvizivisa-kusvika pamusika weEU. UL 9540 ndeyechitatu-bato rakaedzwa uye rinodiwa kuti iiswe kuNorth America. Zvitupa zvakasiyana zvemisika yakasiyana-Jensen Hughes anoputsa kuenzanisa pano. Kana iwe uri kutumira pasi rose, bhajeti kune ese ari maviri.
Mubvunzo: Izvi zvinoshanda chete kumabhatiri e lithium-ion?
A: UL 9540 ndeyechemistry-agnostic{2}}inovhara electrochemical, mechanical, thermal, even hydrogen-based storage. Zvakadaro, UL 9540A's test process yakavakirwa zvakanyanya kutenderedza lithium{{6}ion thermal runaway behaviour (LFP neNMC kunyanya). Kana uri kushanda neasiri-lithium chemistry, chimiro chichiri kushanda asi mamwe maedzo anogona kusiyana.
Mubvunzo: Ko kana BESS yangu yakakura kupfuura 50 kWh?
A: Ipapo iwe unoda UL 9540A bvunzo data mukuwedzera kune UL 9540 rondedzero. Same inoenda kune kumisikidzwa ine isingasviki 3 tsoka dzepakati pakati pemayuniti. Pasina iyo data, iyo AHJ inogona kuda yakafara nzvimbo (inokudhura iwe ivhu), raira yakawedzera kudzvanywa kwemoto (kukubhadhara iwe mari), kana kungoti kwete.
Mubvunzo: Ndinogona kusvetuka UL 9540 ndoita ongororo yemunda pane kudaro?
A: Nehunyanzvi, hongu-NRTL inogona kuongorora-panzvimbo yepasaiti kuitira kuiswa kwacho. Asi ongororo dzakaitwa purojekiti-chaiyo (hadziende kune saiti inotevera), kazhinji inodhura pachikamu chimwe chete, uye haishande kune zvekutengesa BESS zvigadzirwa zviri kuiswa pamwero. Isu takaita kuti vatengi vaedze nzira iyi vodzoka vachibvunza nezve masisitimu akanyorwa zvakanaka mushure mekuongorora kwechipiri kudhura kupfuura yekutanga.
Mubvunzo: UL inovimbisa kuti chirongwa changu chinotenderwa here?
A: Zvinotora iwe zvakanyanya nzira ipapo. Kufona kwekupedzisira kuchiri neiyo AHJ yemuno, uye mamwe masimba anoisa zvimwe zvinodiwa pamusoro. California'sUL 9540Byezvirongwa zvekugara ndiyo inonyanya kukosha muenzaniso. Gara uchitarisa zvinodiwa nekodhi yemuno nguva ichiripo-usati wazvipira kune imwe system.
Gwaro iri rinochengetwa nePolinovel technical team. Pamibvunzo-yakanangana nechirongwa, tinokurudzira kushanda neEngineer of Record, AHJ inoenderana, uye NRTL inokwanisa. Kana iwe uchida kutarisa zvinyorwa zvedu kune chaiyo system,taura nesu pano.
