Photovoltaic off-grid inverter

Product Sumo
Iyo PV off-grid inverter isimba rekushandura simba rinosundidzira-kudhonza rinowedzera kupinza DC simba uye yobva yarishandura kuita 220V AC simba kuburikidza ne inverter bhiriji SPWM sinusoidal pulse width modulation tekinoroji.
Kufanana negridi-yakabatana inverters, PV off-grid inverters inoda kushanda kwepamusoro, kuvimbika kwepamusoro, uye huwandu hwakawanda hwemagetsi ekupinza DC; mune yepakati-uye yakakura-yakakura PV masimba emagetsi, kubuda kweiyo inverter kunofanirwa kuve sinusoidal wave ine yakaderera kukanganisa.

7. High frequency transformer isolation, diki diki uye chiedza uremu.
8. Yakashongedzerwa neyakajairwa RS232/485 yekutaurirana interface, yakanakira kudzora kutaurirana kure.
9. Inogona kushandiswa munzvimbo iri pamusoro pe5500 metres pamusoro pegungwa.
10, Nekupinza reverse yekudzivirira yekubatanidza, yekuisa undervoltage dziviriro, yekuisa overvoltage dziviriro, yakabuda overvoltage dziviriro, yakabuda yekudzivirira yakawandisa, inobuda pfupi dunhu kuchengetedza, overheat kudzivirira uye mamwe mabasa ekudzivirira.

Yakakosha tekinoroji paramita ye-off-grid inverters
Paunenge uchisarudza off-grid inverter, kunze kwekuteerera kune yakabuda waveform uye yekuzviparadzanisa yerudzi rwe inverter, kune akati wandei ehunyanzvi paramita akakoshawo zvakanyanya, senge system voltage, simba rekubuda, peak simba, shanduko inoshanda, switching nguva, etc. Kusarudzwa kwezviyero izvi zvine simba guru pakuda kwemagetsi emutoro.
1) System voltage:
Ndiyo voltage yebhatiri pack. Iyo yekupinza voltage ye-off-grid inverter uye inobuda voltage yemubati zvakafanana, saka kana uchigadzira nekusarudza modhi, teerera kuti urambe wakafanana nemutongi.
2) Simba rekubuda:
Off-grid inverter inobuda simba rekutaura ine marudzi maviri, imwe inoratidzika simba kutaura, iyo unit ndeye VA, iyi ireferenzi yeUPS chiratidzo, iyo chaiyo inobuda inoshanda simba inodawo kuwedzera iyo simba chinhu, senge 500VA off-grid inverter, iyo simba chinhu 0.8, iyo chaiyo inobuda inoshanda isimba 400W, kureva kuti, senge, inokwanisa kutyaira 400W, inogona kutyaira 400W mudhiraivha. etc.; chechipiri ishoko rinoshanda remagetsi, iyo unit ndeye W, senge 5000W off-grid inverter, iyo chaiyo inobuda inoshanda simba i5000W.
3) Peak simba:
MuPV off-grid system, mamodule, mabhatiri, inverters, mitoro inoumba hurongwa hwemagetsi, inverter inobuda simba, inotarwa nemutoro, mamwe mitoro inductive, senge air conditioners, pombi, nezvimwewo, mota mukati, simba rekutanga rakapetwa ka3-5 simba rakayerwa, saka iyo off-grid inverter ine zvakakosha zvinodiwa pakuremedza. Iyo peak simba ndiyo yakawandisa huwandu hweiyo off-grid inverter.
Iyo inverter inopa kutanga-up simba kumutoro, chikamu kubva kubhatiri kana PV module, uye yakawandisa inopiwa nemagetsi ekuchengetedza zvikamu mukati me inverter - capacitors uye inductors. Macapacitors uye inductors ese ari maviri ekuchengetedza simba zvikamu, asi mutsauko ndewekuti ma capacitors anochengetedza magetsi emagetsi nenzira yemunda wemagetsi, uye iyo yakakura kugona kweiyo capacitor, iyo yakawanda simba inogona kuchengeta. Inductors, kune rumwe rutivi, chengetedza simba muchimiro chemagnetic field. Iyo yakakura iyo magnetic permeability yeinductor core, iyo yakakura inductance, uye yakawanda simba rinogona kuchengetwa.
4) Shanduko inoshanda:
Off-grid system yekushandura inoshanda inosanganisira zvinhu zviviri, imwe ndeyekushanda kwemuchina pachawo, off-grid inverter circuit yakaoma, kuti uende kuburikidza ne-multi-stage shanduko, saka kushanda kwese kwakadzikira zvishoma pane grid-yakabatana inverter, kazhinji pakati pe80-90%, iyo yakakura simba reinverter muchina kunyatsoshanda, yakakwira-frequency system yekuzviparadzanisa yakakwira kupfuura iyo frequency isolation yakakwira. Chechipiri, kushanda kwebheteri kutengesa uye kuburitsa, iyi ndiyo mhando yebhatiri ine hukama, apo photovoltaic simba rekugadzira uye kutakura simba rekubatanidza, photovoltaic inogona kupa zvakananga mutoro wekushandisa, pasina chikonzero chekufamba kuburikidza nebhatiri kutendeuka.
5) Kuchinja nguva:
Off-grid system ine mutoro, pane PV, bhatiri, utility matatu modes, kana bhatiri simba risina kukwana, shandura kune utility mode, pane nguva yekuchinja, mamwe off-grid inverters anoshandisa electronic switching switching, nguva mukati me10 milliseconds, makombiyuta edesktop haazovharidzi, kuvhenekera hakuzoiti. Mamwe ma-off-grid inverters anoshandisa relay switching, nguva inogona kudarika 20 milliseconds, uye komputa yedesktop inogona kudzima kana kutangazve.
