I've been here for 5 months - I joined during that time. Like some I got here via a Harbor Freight kit. Unlike most I don't have an RV, house or shed; just a need to power 2 (maybe more) PTZ video cameras. I watched a couple Will youtube videos - put up a system and blew my charge controller first thing. From there I got a new charge controller and several more hours of videos (to include harsh weather battery banks and solar panel tracking arrays) - I'm here asking for help. I connected my system but it didn't run through the night. I've read several admonishments about doing the math so went to AltE and:
----------------
Battery Bank Sizing:
Watt Hours/Day: 240, Days w/o sunshine: 2, Lowest Temp: 30F
Results:
Battery Bank Capacity: 1546, Battery Bank Voltage: 12V, Battery Bank Capacity: 129 amp hours, 3 String Configuration: 43 amp hours/String (Yikes!)
Panels:
Exposure: Indianapolis/5 sun hours, Solar Power Needed: 62.4W or .06 kW, Solar Panels Needed: 4 - 20W or 1 100W, Solar Charge Controller: 7amps or 9 amps
-----------------
I feel like I'm close but don't want to spend more money until I have it figured out. I personally benefited from the folks who did diagrams and pictures so I could get a visual context about what was going on. I now have 3 batteries (exactly the same 12V 35AH) and a 100W panel (originally just 4 - 25W Harbor Freight panels). The requirement is to operate Qty 2 - 24hr/day PTZ cameras (10Wh). What can I use on this Apollo 13 return-to-earth project to meet my goal? BTW I use a TP-Link external access point to get video from cameras (that works great - I have awesome WiFi in backyard).
