Current Rating of the Cable

Selected cable size and Type

Cable from PV array to battery bank

$I_{c a b} = I_{r c c}^{M} \times N_{p m} \times F_{s a f e} = 1166625 A$

3 × 35 mm² Insulated Flexible Copper Cable

Inverter to DB of residential house

Current at Inverter output:

$I_{o i} = \frac{P_{i}}{V_{o i} \times P_{f}} = \frac{4000}{220 \times 0.8} = 22.73 A$
