The UPS will be configured to properly shutdown the above equipment if the power has been out for over 5 minutes.

Mac Studio ( Max power consumption 215 W)Ģ. The charging is from the grid - not the Powerwall.ĭear experts, I do need your advice badly on what UPS to employ with my modest system:ġ. The power consumed during EV charging is in the order of 10 kilowatts - much much more than any computers or appliances (unless there are multiple A/C units). It is set to start charging at 11:00 PM - because of our time-of-use electric rate plan, it is cheapest at this time. Powerwalls give you whole-house UPS and also some rate arbitrage as described above, but they are expensive so I'm not sure whether they "pay for themselves" - except if you count peace of mind.Ĭurrently we have one EV (Tesla Model 3) in our home. The rules are complicated because basically the utility doesn't want users to fill up the Powerwall when rates are cheap and then sell it back to the utility when rates are highest. The Powerwalls are drained till they reach 40% capacity (settable) with the remainder kicking in only if there is a power outage. I have set it so that when our electricity rates are highest (3:00PM to 9:00PM) the house is powered by the Powerwall and the electricity generated by the Solar panels is sold back to the grid (since the rates are highest). Our Powerwalls (we have 2) can only get charge from our Solar Array, not from the grid. The charging is from the grid - not the Powerwall.
