HOW IT WORKS

Energy, simplified

for your home

Store energy when it’s cheaper.
 Use it when it matters.

How your system works — automatically

No solar panels. No complex setup.


Every POLAR system combines battery and inverter in one—pre-configured to manage your energy automatically.

It charges when rates are low, and powers your home when they rise—so you spend less without thinking about it.

Charge when rates are low

Your system stores energy from the grid when electricity is cheaper.

Grid

Stored and ready

Energy is held in your battery and managed seamlessly by the inverter.
