With Powerwall, energy works for you

We adapt Tesla Energy systems to Ukraine's conditions for stable operation and cost control.

Energy independence and backup

Powerwall supports backup power and automatic switching.

Cost reduction

Stored energy is used during peak hours for savings.

Clean energy and resilience

Integration with solar generation and stability of energy supply.

Two backup scenarios

1

Full home backup

Powers your entire home during an outage.

2

Critical loads backup

For lighting, internet, refrigerator, security systems, heating, pumps, or other essential equipment.

The sun charges Powerwall. Powerwall powers your home.

Powerwall can work with a new or existing solar system. During the day, solar generation charges the battery; in the evening, at night, or during an outage, that energy powers your loads.
