June 3rd, 2023, PSE (Puget Sound Energy), our power utility, energized our solar system and house batteries. On May 25th, we had 44 photovoltaic (PV) panels feeding two SolarEdge inverters installed producing 15.5 kW. That's a lot of energy. The house draws a mere 2.3 kW at this moment, the batteries and Tesla are topped off, so 13.2 kW is going back to the grid, earning credits towards our power this winter. The system includes two Tesla PowerWall batteries with a capacity of 13.5 kWh each and a Tesla car charger (plugged into my Model Y with a capacity of 81 kWh).  I learned so much during this process, that I had to write articles to share with my geeky friends, so here is the first! Why did we have to wait to have the system on? Before this system was installed, we had a single direction meter from PSE. This means that the meter was measuring the flow of power in either direction as consumption. If we had turned on the system, the utility would have charged us for the 13.2kW fl
