III. Kubara Igihe cyo Gukoresha: Bateri Izamara Igihe Kingana Iki?

Igihe cyo gukora kwa inverter giterwa n'ubushobozi bwa bateri × voltage ya sisitemu ÷ imbaraga zo gutwika × imikorere myiza yo guhindura.

Formula y'ibanze

Ubushobozi bwa Bateri (Ah) = (Ingufu zo gutwara × Igihe cyo gukora cyifuzwa) ÷ (Volteji ya Bateri × Ubujyakuzimu bwo Gusohora)

• Ubujyakuzimu bw'Imyuka Isohoka (DoD) – 0.8 kuri lithiyumu, 0.5 kuri aside ya lead (igabanyirizwa 20% kugira ngo wirinde ko isohoka rirenze urugero)

Urugero: Ku mutwaro wa 3000W kuri sisitemu ya 48V ikora isaha imwe hamwe na bateri za lithium:
(3000 × 1) ÷ (48 × 0.8) ≈ 78Ah

Ingero z'Ishyirwa mu Bikorwa mu Buryo Bufatika

Kugereranya Ubwoko bwa Bateri

Bateri za Lithium fer phosphate (LiFePO₄) ubu zigize 72% by'isoko ry'ingufu. Igipimo cyazo cyo gusohora 1C ni cyiza cyane ku bikenerwa na inverter. Igihe cy'urugendo: kugeza ku nshuro 3.000 kuri 80% DoD, kirenze cyane ukwezi kwa aside ya lead 500 kuri 50% DoD. Nubwo igiciro cya mbere kiri hejuru, agaciro k'igihe kirekire ni keza cyane.

Incamake y'ingenzi: Ku ikoreshwa rya buri munsi cyangwa kenshi hanze y'umuyoboro w'amashanyarazi, LiFePO₄ ni yo shoramari ryiza. Ku ishoramari rimwe na rimwe (inshuro nke mu mwaka), aside ya lead ishobora kuba ikiri yemewe.

IV. Guhitamo sisitemu ya Voltage: 12V, 24V, cyangwa 48V?

Guhitamo ingufu z'amashanyarazi muri sisitemu bigira ingaruka zitaziguye ku mikorere myiza n'umutekano. Ingufu nyinshi zisaba ingufu nyinshi z'amashanyarazi.

Urugero rwa inverter ya 3000W:

• Sisitemu ya 48V → Bateri ya 150–200Ah (igihe cy'amasaha agera kuri 5)
• Sisitemu ya 24V → 300–400Ah
• Sisitemu ya 12V → ntiyemerwa (umuvuduko ukabije utera gushyuha cyane)

Impamvu voltage nyinshi ari nziza: Voltage nyinshi bivuze ko ingufu z'amashanyarazi ari nke, bigabanya igihombo cy'umurongo, bigabanya ubushyuhe, kandi bikongera imikorere myiza muri rusange. Ku bijyanye na sisitemu zirengeje 3000W, 48V ni yo mahitamo meza cyane.

V. Inzira z'inganda n'inama ku kugura
