Pankhani ya mphamvu zatsopano, ma inverters a photovoltaic ndi ma inverters osungira mphamvu ndizofunikira kwambiri, ndipo zimagwira ntchito yofunika kwambiri pamoyo wathu. Koma kodi pali kusiyana kotani pakati pa ziwirizi? Tidzasanthula mozama ma inverters awiriwa kuchokera pamapangidwe, ntchito, zochitika zogwiritsira ntchito, ndi zina.
01 Kusiyana kwamapangidwe
Choyamba, kwenikweni, inverter ndi chipangizo chomwe chimasintha mphamvu ya DC kukhala mphamvu ya AC. Amagwiritsa ntchito mawonekedwe osinthika a zida za semiconductor (monga ma transistors am'munda kapena thyristors, etc.) kuti aziwongolera mphamvu zamagetsi zamagetsi komanso zamakono kudzera pakusintha mwachangu, potero kukwaniritsa kutembenuka kuchokera ku DC kupita ku AC.

Inverter yosungiramo mphamvu (PCS) ndi lingaliro lalikulu, lomwe limaphatikizapo kutembenuka ndi kuwongolera mphamvu zamagetsi pogwiritsa ntchito zida zamagetsi zamagetsi kuti akwaniritse kufalitsa mphamvu, kutembenuka ndi kuwongolera. PCS makamaka imaphatikizapo rectifier, inverter, DC / DC kutembenuka ndi zigawo zina za module, zomwe module inverter ndi imodzi mwa zigawo zake.

02 Zosintha
Kugwira ntchito, chosinthira cha photovoltaic makamaka chimayang'ana pakusintha mphamvu ya DC yopangidwa ndi mapanelo a solar photovoltaic kukhala mphamvu ya AC kuti igwiritsidwe ntchito pa gridi yamagetsi kapena zida zamagetsi. Imakulitsa mphamvu yotulutsa mphamvu ya solar photovoltaic array kudzera m'mabwalo amkati ndi ma modules owongolera, imapanga njira zingapo pamagetsi a DC opangidwa ndi mapanelo a photovoltaic, ndipo pamapeto pake imatulutsa mphamvu ya AC yomwe imakwaniritsa zofunikira za gridi yamagetsi.
Ma inverters osungira mphamvu amasamalira kwambiri kutembenuka kwa njira ziwiri ndikuwongolera mwanzeru mphamvu zamagetsi. Simangotembenuza mphamvu ya DC kukhala mphamvu ya AC, komanso imasintha mphamvu ya AC kukhala mphamvu ya DC kuti isungidwe. Kuphatikiza pa kuzindikira kutembenuka kwa DC kupita ku AC, imathandiziranso kulumikizana kwa BMS/EMS, kasamalidwe ka magulu, kuchuluka kwa ndalama ndi kutulutsa mphamvu, kasamalidwe kodziyimira pawokha pakumeta nsonga ndi kudzaza zigwa, komanso kukonza mwanzeru zamalipiro ndi kutulutsa ntchito zosungira mphamvu. dongosolo.
03 Zochitika zogwiritsira ntchito
Ponena za zochitika zogwiritsira ntchito, ma inverters a photovoltaic amagwiritsidwa ntchito makamaka pamagetsi opangira magetsi a dzuwa, monga machitidwe a photovoltaic apanyumba, mafakitale ndi malonda a photovoltaic ntchito, ndi malo akuluakulu opangira magetsi. Ntchito yake yayikulu ndikusinthira mphamvu ya DC yamagetsi adzuwa kukhala mphamvu ya AC ndikuyiphatikiza mu gridi.

Ma inverters osungira mphamvu amayang'ana kwambiri pakugwiritsa ntchito mumagetsi osungira mphamvu zamagetsi, monga malo osungira magetsi, mtundu wapakati kapena zingwe, zochitika zamakampani, zamalonda ndi zapakhomo. Muzochitika izi, ma inverters osungira mphamvu amatha kugwiritsa ntchito bwino ndikusungira mphamvu zowonjezereka poyang'anira mwanzeru njira yolipirira ndi kutulutsa, kupereka mphamvu zokhazikika komanso zodalirika pazochitika zosiyanasiyana zogwiritsira ntchito.
04 Chithunzi cha inverter system yosungirako mphamvu
Mfundo zofanana ndi zosiyanaPonena za mfundo zomwe zimafanana, zonsezi ndi zipangizo zamagetsi zamagetsi, zomwe zimagwiritsidwa ntchito potembenuza ndi kulamulira mphamvu zamagetsi kuti akwaniritse ntchito yokhazikika yamagetsi. Onse ayenera kukwaniritsa miyezo ina yachitetezo chamagetsi kuti awonetsetse kuti zidazo zikuyenda bwino. Kuphatikiza apo, popeza ma inverters osungira mphamvu amafunikira machitidwe ophatikizika a batire, ndalama zawo ndizokwera kwambiri. Ntchito ya photovoltaic inverters ndi yosavuta, choncho mtengo wake nthawi zambiri umakhala wotsika. Panthawi imodzimodziyo, ma inverters osungira mphamvu amakhalanso ndi zofunikira zachitetezo. Kuphatikiza pakukwaniritsa miyezo yoyambira yachitetezo chamagetsi, chitetezo cha kasamalidwe ka batri ndi njira zodzitetezera ngati batire yalephera kuyeneranso kuganiziridwa.
05 Fotokozerani mwachidule
Pomaliza, pali kusiyana koonekeratu pakati pa ma inverters a photovoltaic ndi ma inverters osungira mphamvu zokhudzana ndi mfundo, zochitika zogwiritsira ntchito, kutulutsa mphamvu, mtengo, ndi chitetezo. Zikafika pazogwiritsa ntchito zenizeni, ndikofunikira kusankha zida zoyenera kutengera zomwe mukufuna komanso zochitika. Kuthandizana ndi AMENSOLAR, monga wotsogola wopanga ma inverter a solar, amatsimikizira mwayi wopeza mayankho abwino, kukopa ogawa ambiri kuti alowe nawo maukonde athu.
