The Pfitzner family wanted to get a Tesla Powerwall for a few reasons.
First, Nick had done the maths and determined that based on his homes energy requirements, that during the day a solar system was an absolute no brainer, as his wife is at home during the day. This meant that the pool pump, washing machine, drier, dishwasher and other electronics, on top of the usual constant loads of a refrigerator, freezer and lights were being used during the day. Nick opted for one of the larger systems, a 6.5kW system consisting of 26 250w Phono solar panels, a SolarEdge Inverter (single phase power supply inverter which is compatible with the Tesla Powerwall) and of course the Tesla Powerwall itself.
Why they went with a Tesla Powerwall system.
Where Nick has calculated the savings is in a chunk of the day time usage (approximately 50% of his energy usage) but a major part in the decision was that his night time usage, being on time of use metering (where electricity is more expensive at night time compared to during the day), the addition to the system of a Tesla Powerwall to cover the night time usage and days where the panels were not covering the energy needs required by the home during the day was also a fantastic decision as he’s managed to shave off a majority of his night time usage too.
