Without grid power? That's going to cost a lot mate, 4000watts every hour for 24 hrs is 96,000watts, we are talking about 98x 360watts panel here which I'm sure will need battery bank of 15x 200ah batteries connected in 24v, I don't know how much these costs in dollars as I'm not from dollar spending country so do the math yourself, oh and you will need 7200 to 10,000 KVA inverter
