Backup Power That Plugs Into a Wall Outlet
Pila Energy's Mesh Home Battery backs up individual appliances by plugging into a standard outlet, then links with other units into one coordinated system.

No Electrician Required
Unlike
a whole-home battery system, which is professionally installed and wired into a
home's electrical panel, the Pila battery plugs directly into a standard
120-volt wall outlet. A person places it near whatever they want to keep
running during an outage, such as a refrigerator, a Wi-Fi router or a sump
pump, plugs the device in, then plugs those appliances into it. Because it
needs no rewiring, the company markets it as usable in a rented home as easily
as an owned one, and portable enough to move between homes. It comes in four
colors and can sit flat, mount on a wall or fit inside a cabinet.
What's Inside the Box
Each
unit stores 1.6 kWh of energy, delivering 2,400 watts continuously and up to
3,600 watts for 30 seconds at a time, with an Expansion Pack available to raise
capacity to 3.2 kWh. The battery uses lithium iron phosphate cells, the same
chemistry used in many electric vehicles and power tools, rated for thermal
stability and a 10-year lifespan under typical household use. Pila says its
engineering team previously worked on Tesla Powerwall and SPAN smart panels,
and the device meets UL safety standards with surge protection, over-voltage
monitoring and temperature regulation built in.
Many Batteries Acting as One
Multiple
Pila units can find each other automatically and link into what the company
calls a Battery Mesh Network, an encrypted local connection exclusive to a
single home that keeps working even if the home's Wi-Fi goes down. Up to 64
batteries can join one mesh, all appearing as a single coordinated system
inside the Pila app rather than as separate, disconnected devices scattered
around the house.
Responding to an Outage in Milliseconds
When
grid power cuts out, Pila switches to battery power in 10 milliseconds without
any action from the person using it. The free Pila app sends outage alerts,
forecasts how long the remaining charge will last, and lets someone control
power at the level of an individual outlet, including shifting a battery to
charge during off-peak electricity rates and discharge during expensive peak
hours.
Already Delivered, With More on the Way
Pila
has already completed six production runs, selling out and delivering units to
customers before this latest expansion; a seventh production run is scheduled
to ship in December 2026. Brooklyn SolarWorks CEO T.R. Ludwig said of the
partnership, "We've put solar on rooftops other companies wouldn't touch,
but storage has always been the missing piece."
