Raspberry Pi takes over the world

OK, if not the world, then 1 outlet at a time!!!
This is a pic of a single relay that is controlled by my Raspberry Pi.
Red = 5VDC, Black = Ground, White = Pin23 (active high)
And an old pc power cord split in 1/2 and a female end installed.
The Ground and Neutral leads feed straight through from the input to the output
The relay switches the hot lead and runs a battery charger drawing 5 Amps AC.
The relay is rated for 10A @ 277V
The Raspberry Pi runs off of my solar array at home and because I have so many items tied to them:
     3 Raspberry Pi's
     1 x 12V HP switch
     1 x Kenwood HF Amateur Radio
     1 x LDG Antenna Tuner
     1 x Radio Shack HTX-242 VHF Amateur Radio

Most days I have enough solar energy to power all my devices.
However if I get several cloudy days together, the voltage can drop and my charge controllers shut down.
Then my Raspberry Pi's shut down...... And that makes me cranky.....

So I have an Arduino monitoring the battery voltage and sends that data via serial to the Raspi
If the battery voltage drops down too much due to lack of sunlight, the charger is turned on for a charge cycle (typically 6-8 hours), and then shuts off.

I plan on making quite a few of these for the many different 120VAC loads that I want to control from my Raspi.

Solar Charge Controller & Battery Bank

The 2 solar panels that are mounted on my deck are wired into the charge controller in my garage:

This in turn is wired into my battery bank(s). I have 4 sets of 2 x 12V batteries that I can use at any time. In addition, they all have 50A Anderson Power Pole connectors to plug into my Go Power 1500W Pure Sine Wave Inverter (yellow box under the charge controllers).

If I lose power at the house & garage, this inverter and associated batteries will run my Radiant Tube heater to keep my garage warm. If it is the middle of winter, I have a 3000W Guardian Generator in the shed that I can bring into the garage to warm up and then run outside to power my furnace & refrigerator in the house.

Solar Panels mounted on the Deck

Another of my hobbies that aligns with Amateur Radio is Solar Power. I just installed 2 x Sharp NE-80EJEA solar panels on the railing of my deck. These complement the 2 that are on the shingles of my garden shed (can't show a pic because the are buried in the 4" on snow that we received last night & today)

Yes, all of those white specs are the snow that is still falling!

These panels have several ratings that are important:
Maximum Power (PMax) = 80.0W
Open-Circuit Voltage (VOC) = 21.6V
Short-Circuit Current (ISC) = 5.15A
Operating Voltage (VPMAX) = 17.3V
Current at VPMAX = 4.63A
Maximum System Voltage = 600V
Maximum Series Fuse = 10A

I've wired the 2 panels in series to deliver 24VDC to my charge controller which is a MorningStar SS-20L-24V
