The software that controls the inverters and produces the dynamic content has kept a log since September 6, 2001, of the following inverter parameters. They are sampled approximately every minute. At the end of each six minute period, the averages of each of the samples occuring during that period are output. From this data, the various graphs and calculations that appear on this web page are produced. Graphs based on the cost of electricity use the correct historical rate and assume a Tier 5 E-EPS surcharge, which we would be paying were it not for our photovoltaic system.
|Date and Time|
|Power produced by each inverter pair|
|Power drawn from or delivered to the power grid|
|Power delivered to loads in the house|
|Grid and Inverter AC voltages|
|State of sun (up or down)|
|DC bus voltages for each of the inverter pairs|
we would consider making this raw data available for other types of analysis.
Some interesting days to look at:
|9/20/2001|| ||Under a 10kW sell limit, a perfect day|
|10/25/2001|| ||Under a 20kW sell limit, a perfect day|
|10/29/2001|| ||A rainy overcast day|
|11/12/2001|| ||A very overcast day, grid power failure 10am to noon|
|7/9/2002|| ||No sell limit, a perfect day|
