China Quality DC Inverter Supplier

Ma inverters a DC amaperekedwa ndi akatswiri opangaCDADA. Malo athu ali ndi mizere isanu ndi inayi yopangira, mothandizidwa ndi zaka 20 zazomwe zidachitika pagululi. Mogwirizana ndi miyezo yapadziko lonse lapansi, zogulitsa zathu zimadzitamandira moyo wautumiki mpaka zaka 25 ndipo zimabwera ndi chitsimikizo chazaka zitatu.

Kodi DC Inverter ndi chiyani?

A DC inverter, omwe amadziwika kuti aphotovoltaic (PV) inverter kapenainverter ya dzuwa, ndi chipangizo chamagetsi champhamvu kwambiri chomwe chimatembenuzaDirect current (DC) zopangidwa ndi solar panels mualternating current (AC) oyenera kulumikiza gridi kapena kugwiritsidwa ntchito kwanuko. Monga chigawo chapakati cha machitidwe opangira magetsi a photovoltaic, inverter imagwira ntchito zingapo zofunika kuphatikizapoKutsata kwamphamvu kwamphamvu kwambiri (MPPT), kulumikizana kwa gridi, kasamalidwe kabwino ka mphamvu, ndi chitetezo chadongosolo.

Ma inverters amakono a PV amagwira ntchito modutsa ma voliyumu olowera kuchokera200V DC mpaka 1500V DC, ndi mphamvu zotulutsa mphamvu kuchokera1kW zokhalamo mpaka ma inverters apakati amphamvu a megawati ambiri. Kuthekera kosinthika kwa ma inverters a premium kumapitilira99%, yokhala ndi mphamvu zolemedwa ku Europe (η) nthawi zambiri kuyambira97% mpaka 98.5%.

Mosiyana ndi otembenuza osavuta a DC-AC, ma PV inverters amaphatikizamachitidwe olamulira anzeru zomwe zimachulukitsa nthawi zonse kukolola mphamvu, kuyang'anira thanzi la machitidwe, ndikuwonetsetsa kuti zikutsatira ma code omwe akusintha. Inverter imagwira ntchito ngati "ubongo" wa photovoltaic system, kugwirizanitsa kayendedwe ka mphamvu pakati pa ma module a dzuwa, mabatire, katundu, ndi gridi yogwiritsira ntchito.

Utsogoleri wa grid code: Kutsata mosamalitsa ma code osinthika a gridi (IEEE 1547-2018, VDE-AR-N 4110, G99) kupangitsa mwayi wopezeka pamsika m'maiko 100+

Smart energy innovation: Mayankho ophatikizika osungira mabatire, kuthekera kwa V2G, ndi nsanja zophatikizira zamagetsi (VPP) zamakasitomala am'badwo wotsatira

Kupanga kwa digito:Kukhazikitsa kwa Viwanda 4.0 ndi kutsata kwathunthu (gawo mpaka chinthu chomalizidwa), kusanthula kwamtundu wolosera, ndi kuyang'anira kowoneka bwino kumawonetsetsa kuti <100ppm chiwopsezo chambiri

Kudalirika kumayang'ana: Moyo wopanga zaka 25, kuyezetsa moyo wofulumizitsa, ndi MTBF yotsimikiziridwa m'munda> maola 100,000

CDADA ndi DC Inverter opanga ndi ogulitsa ku China. Fakitale yathu imagwira ntchito m'mafakitale osiyanasiyana monga makina amagetsi, makina opangira makina, komanso kupanga mafakitale, kupereka mayankho osinthika a OEM/ODM.
