ʻEhia mau ʻaʻa e holo ai i ka rv ac?

No ka holo ʻana i ka ea ea RV ma nā ʻokoʻa, pono ʻoe e koho ma muli o kēia:

1. Koi mana o ka Unite AC: Pono maʻamau nā ʻea ea RV ma waena o 1,500 a 2,000 watts no ka hana ʻana, ʻoi aku ka nui o kekahi manawa ma muli o ka nui o ka ʻāpana. E noʻonoʻo kākou i kahi ʻāpana AC 2,000-watt ma ke ʻano he laʻana.
2. Voltage Battery and Capacity: Hoʻohana ka hapa nui o nā RV i nā panakō pākahiko 12V a i ʻole 24V, a hoʻohana paha kekahi i 48V no ka pono. Ana ʻia nā mana pākahi maʻamau i nā hola amp (Ah).
3. Hoʻoikaika Inverter: No ka holo ʻana o ka AC ma ka mana AC (alternating current), pono ʻoe i kahi mea hoʻohuli e hoʻohuli i ka mana DC (direct current) mai nā pila. He 85-90% maikaʻi nā mea hoʻohuli, ʻo ia hoʻi, ua nalowale kekahi mana i ka wā o ka hoʻololi ʻana.
4. Manawa holo: E hoʻoholo i ka lōʻihi o kāu hoʻolālā e holo i ka AC. No ka laʻana, ʻo ka holo ʻana iā ia no 2 mau hola me 8 mau hola e hoʻopilikia nui i ka nui o ka ikehu e pono ai.

Laʻana Helu

Manaʻo ʻoe makemake ʻoe e holo i kahi ʻāpana 2,000W AC no 5 mau hola, a ke hoʻohana nei ʻoe i nā pihi 12V 100Ah LiFePO4.

1. E helu i ka nui o nā hola Watt e pono ai:
   • 2,000 watts × 5 hola = 10,000 watt-hola (Wh)
2. He mooolelo no ka Inverter Efficiency(manaʻo ʻia he 90% ka maikaʻi):
   • 10,000 Wh / 0.9 = 11,111 Wh (hoʻopuni ʻia no ka poho)
3. E hoohuli i Watt-Hours i Amp-Hours (no ka batika 12V):
   • 11,111 Wh / 12V = 926 Ah
4. E hoʻoholo i ka helu o nā Bateri:
   • Me 12V 100Ah mau ʻaniani, pono ʻoe i 926 Ah / 100 Ah = ~9.3 mau pihi.

No ka mea, ʻaʻole i loaʻa nā ʻāpana i nā hakina, pono ʻoe10 x 12V 100Ah mau pihie holo i kahi hui 2,000W RV AC no kahi o 5 mau hola.

Nā Koho ʻokoʻa no nā hoʻonohonoho like ʻole

Inā hoʻohana ʻoe i kahi ʻōnaehana 24V, hiki iā ʻoe ke hoʻokaʻawale i nā koi amp-hola, a i ʻole me kahi ʻōnaehana 48V, he hapahā. ʻO kahi ʻē aʻe, me ka hoʻohana ʻana i nā pihi nui (e laʻa, 200Ah) e hōʻemi i ka nui o nā ʻāpana e pono ai.
