Backup power is one of the biggest reasons families consider a solar battery. But backup performance can vary significantly depending on the battery, inverter and home wiring.

In a three-phase home, some battery systems may only back up selected circuits or one phase of the property. That may be enough for lights, Wi-Fi and refrigeration, but it may not support larger three-phase appliances.

The upcoming Powerwall 3P is expected to offer stronger three-phase backup capability because it is being designed specifically for three-phase homes.

For homeowners, this could mean a more practical backup solution for larger properties where the goal is to keep more of the home running during an outage.

At Velocity Solar, we can help assess what level of backup makes sense for your home, including which circuits should be protected and whether your current solar system is ready for a battery.
