Backyard Summertime Nature in New Jersey.

Day two putting up an electric fence around the Forsythia and Lilac bushes we planted earlier this spring.  It is hot out. One hour of the work recorded as a time-lapse video using a Garmin VIRB-360 camera.

Daily Electric Energy Used (66.9 kWh) from Sense and Daily Solar Electric Energy Produced (57.2 kWh) from SolSystems and Locus Energy. A bit more Sun, but I ran a load of laundry (3.1 kWh), a load of dishes, and cooked dinner in the oven (0.3 kWh) today. The WaterFurnace geothermal HVAC had to work harder (26.8 kWh) because of the extra heat generated by the laundry, dishwasher, and oven. Daily net deficit 9.7 kWh.

One note — the WaterFurnace Symphony software indicated the system used 14 kWh, however the Sense Energy monitor indicated that the geothermal heat pump used 26.3 kWh. I tend to believe the Sense numbers since they more closely the energy being recorded at the external power company (PSE&G) meters. I’ve asked the WaterFurnace folks in the past about the discrepancy, but they didn’t have a good answer. The Sense folks told me they thought that the WaterFurnace/Symphony system was only measuring one phase of the energy even though the system is powered by the 220V circut (using two phases). I wish an electrical engineer that understands this better would correct me here.
