I have 8 - 280 watt solar panels, a 3500 watt inverter and 12 batteries. I am ready to get it all installed to replace edenorte power. I currently use about 850 to 900 KW hours per month so I am hoping this will be sufficient to do that. I run 7 to 9 fans 24 hours and 150 watts of light bulbs throughout the entire night. No ac of course but a midsize nedoca refrigerator and a flat screen TV several hours a day and a few during the night. I will be keeping the edenorte connected to use the ac, water heater and occasional shortages on cloudy days.
I have a spare 2000 watt inverter and can utilize the old battery bank (8) for outside lighting for a while if the panels are strong enough to charge all of it.... which I doubt.
My immediate question is what size controller do I need, the best place to buy it since I only need that and what it might cost me. It has been suggested that I need an 80 amp but also that I could use 2 - 35 amp which would be cheaper. Any advice would be appreciated.
