My next home will need to be off grid and this is the system I have in mind. I've only ever built one off-grid system before and it was much smaller.
Location: On the equator, min temp 5C max about 30C
1400W array, 7x200w panels
Tristar 45A PWM controller
18x 70Ah 12V FLA batteries (chosen for price) total Ah at 24V = 630Ah
Power use per day if we go crazy would be about 2.6kwh. We have lived in off grid before with only 1x 70Ah to sustain us so we do know how to conserve power if necessary.
Will the array be sufficient for the battery bank?
Is it crazy to have 18 FLA batteries to save some money rather than a few higher capacity sealed or FLA batteries? I already have 6 70AH batteries I can use, which is why I'm leaning towards 70Ah, in addition to the fact that they are the cheapest battery in terms of $/Ah.
