14 kw ground mount solar adding 3 kw roof solar.
I have 14 kw solar going into four 15 amp breakers at the ground mount. from there the # 4 wire goes 30 ft to a solar main disconnect with 200 amp round fuses L1 and L2. From the disconnect it has a line tap before the 200 amp main house disconect. My question is can I put a 100 amp breaker box before the solar disconnect and put the ground mount on a 80 amp breaker (four 15 amp breakers. 15 x 4 = 60. 60 x 1.25= 75) and the new 3 kw on a 15 amp breaker?
