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.

Can back feed when the grid is up. Can't back feed when the grid is out. It has an onboard relay to disconnect from the grid when there is an outage.

Yes, it has 4 outlets and can turn them off automatically based on your priority settings.

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.

Suicide cords are from dumb generators. Pila has smart safety controls that don’t feed power back through the plug unless it’s connected to grid.
Utah just passed a law allowing this & Germany has allowed it for years.

I think the modern path for new builds is a SPAN Panel which adds an MID, breaker level load control, & flexibility of install.

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.

Great question, our device has a metal case that offers much better thermal performance than your typical camping battery.
Yes, you can boil a kettle with it!

Generators in this price point are loud, low power, unreliable, & even require maintenance.

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.

I think offering financing & working with utilities to further reduce the price will be a key unlock for more affordability.

Zigbee is on the same frequency as WiFi and therefore suffers from all the same issues that WiFi has interference and limited range. SolarCity used Zigbee for communication with solar inverters. It was very unreliable. Tesla moved to WiFi after acquiring SolarCity.

Unfortunately, AC powerlines are extremely noisy. Powerline comms are used by SolarEdge to communicate with their optimizers. Because it’s a small closed loop there is far less noise than the home grid.
