Save money

How your
system works
Charging the battery
Your battery will charge with surplus solar energy or directly from the grid, powering your home when the sun goes down or during an outage.
Backup power during outages
If an outage happens, the battery instantly disconnect your home from the grid and starts powering essential appliances. Depending on your system setup, the battery can provide 1-2 days of backup.
Saving on energy
Use stored energy to lower bills by switching to battery power when electricity is priciest and charging when it’s cheapest (or from surplus solar).
