Awesome to see BYD continue to innovate! I wish Tesla continued to push on powertrain improvements like this rather than making a triangle shaped truck.
This is mostly correct. One additional feature is that it can back feed when the grid is up. This allows you to save money on your energy, charging when energy is cheap or from solar and discharging when energy is expensive.
Yes & no, there are two reasons to push power back:
1- to save money on energy, charge when cheap discharge when expensive. Pila can do this.
2- to backup. Pila can’t do this. It can only backup appliances plugged into it.
Pila can only back feed on-grid. Pila has a built in Microgrid Interconnect Device (MID). When an outage is detected, like Powerwall Pila opened the MID and continues to power downstream loads that are plugged into Pila.
There is a MID (Microgrid Interconnect Device) built into the battery which opens when there is a grid outage. During an outage power is only supplied to devices plugged into Pila.
