Version 4.3

Help Please! Starting with v4.3 the main task is now improving the predefined households. Therefore the following request for help: Please help improve the LPG by increasing the data basis. Two things would help a lot: First, if you have measured device profiles (doesn’t really matter which devices), please consider donating some to the LPG. Second, it would be helpful to have behaviour data about more households. So if you have time, please consider if it would be possible to keep track of all the actions in your household for a few days in a 15 min resolution.

Energy Arbitrage Potential of a 7 kWh Battery for an average German Household Part 2

In the last post there was no data about the energy delivered by the PV field and how it is split between battery, direct use and grid. Fortunately this is an omission that is rather easily remedied. The charts below show how energy is distributed over the year. The small difference in the battery consumption is the result of a slight variation in the consumption due to the random number generator in the LPG.
