[solar-ranch]

Need to power a 10watt Lorex WiFi camera, 9 watt Unifi Wifi Receiver, and 7 watt eero wifi router for 10hrs/day (260 watt hours/day) at ranch gate in Texas hill country (mostly sunny at 30 degrees N latitude; 1555 foot altitude). Estimate for 2 days is 260x2= 520 watt hrs. At 50% capacity for SLA battery = 1040 watt hrs required total. Battery bank to use (3 SLA AGM VMAX 12v 35Ah in parallel = 12v 105 Ah = 1260 watt hrs? Use EPEVER 20 amp MPPT charge controller? Use Giandel 600 watt pure sine wave inverter? Use 2 100 watt Renogy solar panels monocrystalline 12V Vmp = 17.9v; Imp = 5.72 amps in parallel? thanks to anyone for checking out this design for errors, etc.
