Inverter ni ubwoko bwigikoresho cyo guhindura amashanyarazi kigizwe nibikoresho bya semiconductor, cyane cyane bikoreshwa muguhindura ingufu za DC mumashanyarazi ya AC, mubisanzwe bigizwe no kuzamura umuzenguruko no guhinduranya ikiraro cya inverter.Kuzamura umuzenguruko bizamura ingufu za DC ya selile yizuba kuri voltage ya DC isabwa nigenzura rya inverter;Inverter ikiraro cyumuzunguruko gihindura imbaraga za DC zongerewe imbaraga mumashanyarazi asanzwe ya voltage ihwanye.
Inverter, izwi kandi nk'umucungamutungo, irashobora kugabanywa muburyo bubiri bwo gutanga amashanyarazi yigenga hamwe na gride ihujwe ukurikije ikoreshwa rya inverter muri sisitemu yo kubyara amashanyarazi.Ukurikije uburyo bwo guhindura imiterere ya moderi, irashobora kugabanywamo indangantego ya kare, intambwe yo guhinduranya intambwe, iniverisite ya sine hamwe no guhuza ibyiciro bitatu.Kuri inverter ikoreshwa muri sisitemu ihujwe na sisitemu, ukurikije ahari cyangwa idahari ya transformateur irashobora kugabanywa muburyo bwa transformateur nubwoko bwa transformateur.Ibyingenzi byingenzi bya tekinike ya sunvolvolic inverter ni:
1. Ikigereranyo gisohoka voltage
Inverter ya pv igomba kuba ishobora gusohora voltage yagabanijwe murwego rwemewe rwo guhindagurika kwinjizwa rya dc voltage.Mubisanzwe, iyo ibipimo byasohotse byapimwe ni icyiciro kimwe 220v nicyiciro cya gatatu 380v, gutandukana kwa voltage guhindagurika bifite ingingo zikurikira.
(1) Mubikorwa bya leta bihamye, gutandukana kwa voltage guhindagurika birasabwa kutarenza ± 5% byagaciro kagenwe.
(2) Gutandukana n’umuriro ntigushobora kurenga ± 10% byagaciro kagereranijwe mugihe habaye ihinduka ryimitwaro.

.Ibisohoka voltage inshuro zisobanurwa mubipimo byigihugu gb / t 19064-2003 bigomba kuba hagati ya 49 na 51hz.
2, umutwaro wibintu
Imbaraga zumutwaro zerekana ubushobozi bwa inverter hamwe numutwaro wa inductive cyangwa umutwaro wa capacitive.Mugihe cyimiterere ya sine, ibintu bitera imbaraga biva kuri 0.7 kugeza 0.9, naho igipimo ni 0.9.Kubireba imbaraga zumutwaro runaka, niba ibintu byingufu za inverter ari bike, ubushobozi bwa inverter busabwa buziyongera, bigatuma igiciro cyiyongera, mugihe kimwe, imbaraga zigaragara za sisitemu ya fotokolike AC loop yiyongera, loop iriyongera, igihombo kiziyongera byanze bikunze, kandi imikorere ya sisitemu izagabanuka.
3. Ikigereranyo gisohoka cyubu nubushobozi
Ibipimo byasohotse byerekana ibyasohotse byasohotse muri inverter mugihe cyagenwe cyerekana imbaraga zingana (ubumwe: A).Ubushobozi bwo kugereranya ibicuruzwa nibicuruzwa byapimwe byapimwe byapimwe hamwe nibisohoka byasohotse muri inverter mugihe ibintu bisohoka ari 1 (ni ukuvuga umutwaro urwanya imbaraga), muri KVA cyangwa kW
