This is my second version of solar power. The first version can be seen in my other instructable http://www.instructables.com/id/My-Solar-Setup/
I did not take pictures as I was building this unit, because I had to make several changes as I was building. If I had this instructable would have 100 pages, so I am showing you my almost finished product.
On this first page you are seeing the closed tote. This tote is a Contico 50 gallon tote with locking lid. You can find these at most local home improvement stores. I did a lot of looking before picking this tote. It was the only tote that would give me the space inside and the strength to hold the weight of the components inside.
There are 5 meters in the front, this gives me the ability to know what is going on in an instance. Starting on the left, the first meter is the amp reading of the solar power that is coming from my solar panels. The second meter is the voltage from the solar panels. The third meter, under the lock, is a battery meter just like a golf cart would have showing the battery percentage in 10% steps. Meter 4 is the amperage being drawn from the battery bank. The last meter on the right is the battery voltage level. At a glance I can see the power in from the solar, power out from the battery bank, and how much power is in the battery bank. I got these meters on eBay, so there not the best but they work for what I am using them for. The amp meters are a little off. You can see that the 4th meter, amps from the battery bank, says 0.0. This is not correct, there is really an amp draw of about 0.5 because of the meters are on all the time. The meters wouldn't have to be on all the time, but I wanted them to be on all the time.
