U Hloka Libetri Tsa Letsatsi Tsa LiFePO4 Tse Kae
Ho khetha matla a betri ke mohato oa bohlokoa molemong oa moralo oa sistimi ea letsatsi. Ha re tsamaee ka mohlala ho bona hore na e etsoa joang:
(1) Maikutlo:
l Tšebeliso ea Matla a Letsatsi le Letsatsi: 5 kWh
l Matsatsi a Boipuso: matsatsi a 2
l DoD e ka Sebelisang Betri: 90% (0.9)
l Ts'ebetso ea Tsamaiso: 95% (0.95)
l Matla a tsamaiso: 48V
l Betri e le 'Ngoe e Khethiloeng: 5.12 kWh ROYPOW LiFePO4 Betri ea Solar
(2) Mokhoa oa Palo:
l Kakaretso ea Tlhokahalo ea Polokelo = 5 kWh/letsatsi × matsatsi a 2 = 10 kWh
l Kakaretso ea Bokhoni ba Banka ea Betri = 10 kWh ÷ 0.9 ÷ 0.95 ≈ 11.7 kWh
l Palo ea Libetri = 11.7 kWh÷ 5.12 kWh = 2.28 libeteri
