Web based solar panel monitoring/managment

I updated the  web code to give a table view.  Voltages are just simulated data, but you get the idea.

I had some time this weekend and made up some cables to connect my second battery to my battery bank. Cables are 1 AWG and used a 1/0  gauge batter terminal connector. Clamped the connector in a vice. Heat it with a blow torch and filled the connector with solder. Once filled I push the cable into the solder. Works pretty bell with the vice take much of the heat away after the torch was removed.

While one end cooled I worked the other cable until complete. Once both cables cooled down. I used   shrink wrapped and marked them with colored tape.

I built up a second voltage and current module... Was almost done and then snapped the corner off the Protoboard. Didnt affect anything but doesnt look good. I like the current sensor but not happy with the way they  work on the board.... need to give some more though on how to lay these out.

I need to make some changes to where the solar panels were located and how they come into house so the controllers and monitoring systems would be close to a network connection. At least the panels are some what portable. here is a messy view of my charge controller. The dusty keyboard monitor are for my ESX box that sits on the top shelf and are not used as part of this project.

I changed the straight line voltage  get code into a function so I can call it will multiple an analog pin number as a variable. Next is to do  turn the current gathering code into a function. This also offers flexibility to have some other chipset get the current and voltage and and all I need to do is fix the called code.

Calling code.

float voltage=get_voltage(A5); /get volatge on A5

Called code.

float get_voltage ( int vpin ) {

float gvolt=(analogRead(vpin)/4.092)/10;

return gvolt;  

Ordered 3 more ACS715 current sensors so I can finish up this project.

Been away from the project due to work and family task. Should be getting back into it soon.

I originally had planned to use a w5100 ethernet shield, but  the shield  ended up using A0-A4... By moving to the non-shield module I now have access to all the analog ports on my arduino.

Took the messy wires and create a module that makes interface a little easier. In the next module I will skip  the voltage divider module and just use a couple of resistors for a cleaner look.

FRONT VIEW.

REAR VIEW.

This jumble of wires has both the current and voltage modules wired up. I need a better sub-module to hold both of these modules. That will be the next task.
