OK folks... for your viewing pleasure. One of our group members is creating quite a monster system. He's in south Florida so wind is a concern and his daily summer usage is around 180kwh PER DAY. He burns through 50kwh running HVAC from sundown until the early hours of the morning. So, we ran some numbers and he bought 3 pallets of 560w panels and will be placing them in two 30ft x 30ft squares on the ground. Since he needs power in summer, we placed the panels nearly flat.

He's got two 12000xp inverters and 55kw of panels. He's gotta use 600amp busbars. I started him with 64kwh of batteries and he'll use 80% of that each night so the plan is to double that as soon as his system is commissioned.

He decided to replace the meter base outside with a new feed thru combo meterbase / main panel. That way he can have grid only sources of power for heat strips and emergency power to each inverter. There will be a transfer switch inside his basement which will feed his old main panel with the grid or his inverters.

He's combining 3 strings of 8 panels into one MPPT on the 12000xp. That set of 24 panels has it's own PV switch out at the panels. Repeat that 4 times and you have 96 panels. Four runs of AWG 8 feeders back to the house.

So.... here are the pictures of progress so far.
