Cabanga ngesilawuli seshaja yelanga njengesilawuli.Iletha amandla kusuka kuhlu lwe-PV kuya ekulayishweni kwesistimu nasebhange lebhethri.Uma ibhange lebhethri selicishe ligcwale, isilawuli sizocisha amandla okushaja ukuze sigcine amandla kagesi adingekayo ukuze sishaje ibhethri ngokugcwele futhi siyigcine ivaliwe.Ngokukwazi ukulawula i-voltage, isilawuli selanga sivikela ibhethri.Igama eliyinhloko lithi “vikela.”Amabhethri angaba ingxenye ebiza kakhulu yesistimu, futhi isilawuli seshaja yelanga siyawavikela kukho kokubili ukushajwa nokushajwa ngaphansi.

Indima yesibili ingaba nzima kakhulu ukuyiqonda, kodwa ukusebenzisa amabhethri "ngengxenye yokushajwa" kungafinyeza impilo yabo kakhulu.Izikhathi ezinwetshiwe ezinesimo sokushaja esiyingxenye zizobangela amapuleti ebhethri elineasidi yomthofu ukuthi afakwe i-sulfate futhi kunciphise kakhulu iminyaka yokuphila, futhi amakhemikhali ebhethri ye-lithium asengozini ngokulinganayo yokushajwa okungamahlalakhona.Eqinisweni, ukusebenzisa amabhethri ehle aze afike kuqanda kungababulala ngokushesha.Ngakho-ke, ukulawula umthwalo wemithwalo kagesi ye-DC exhunyiwe kubaluleke kakhulu.Ukushintsha kwe-low voltage disconnect (LVD) okufakwe nesilawuli sokushaja kuvikela amabhethri ekuchithweni kakhulu.

Ukushaja ngokweqile zonke izinhlobo zamabhethri kungabangela umonakalo ongalungiseki.Ukushajwa ngokweqile kwamabhethri e-lead-acid angabangela ukufutheka okukhulu okungase “kubilise” amanzi, kulimaze amapuleti ebhethri ngokuwadalula.Esimeni esibi kakhulu, ukushisa ngokweqile nokucindezela okuphezulu kungabangela imiphumela yokuqhuma lapho kukhululwa.

Ngokuvamile, izilawuli zokushaja ezincane zifaka isifunda sokulawula umthwalo.Kuzilawuli ezinkudlwana , amaswishi okulawula umthwalo ahlukene kanye nama-relay angaphinda asetshenziselwe ukulawula ukulayisha kwe-DC imithwalo efika ku-45 noma 60 Amps.Eceleni kwesilawuli sokushaja, umshayeli odluliswayo ubuye asetshenziswe ngokujwayelekile ukuvula nokuvala ama-relay ukuze alawule ukulayisha.Umshayeli we-relay uhlanganisa iziteshi ezine ezihlukene zokubeka phambili imithwalo ebaluleke kakhulu ukuze ihlale isikhathi eside kunemithwalo engabalulekile kangako.Kuwusizo futhi ekulawuleni ukuqalisa kwejeneretha okuzenzakalelayo kanye nezaziso ze-alamu.

Izilawuli zokushaja zelanga ezithuthuke kakhulu zingaphinda ziqaphe izinga lokushisa futhi zilungise ukushajwa kwebhethri ukuze zigcwalise ukushaja ngendlela efanele.Lokhu kubizwa ngokuthi isinxephezelo sezinga lokushisa, esikhokhisa amandla kagesi aphezulu emazingeni okushisa abandayo kanye ne-voltage ephansi uma kufudumala.
