Tesla Powerwall

Powerwall is a rechargeable home battery system that stores energy from solar or from the grid and makes it available on demand. It can power your home during the night or back up your home in the event of a power outage....

• Increase Your Energy Independence
  
  Reduce the electricity that you get from your utility. Power your home with the solar energy stored in your battery, even when the sun goes down.
• Resilient Backup Power
  
  During a power outage, your battery can power your most needed lights and appliances, and sometimes your whole home.
• Battery Protection
  
  Your Tesla Powerwall comes with a limited manufacturer warranty for the term of your agreement.  We take care of maintenance and repairs. Even after your agreement ends, the battery will still have capacity as outlined in your warranty.
• Protection from Peak Rates
  
  If you live in a market with time of use (TOU) rates, your battery will be automatically configured to protect you from peak rates and maximize your net metering credits.

Generac's PWRcell - a battery storage system that harnesses power from the sun to help reduce your electric bill and provide backup power during utility power outages.

PWRcell's revolutionary technology captures and stores electricity - either from solar panels, or the electrical grid. It allows you to use stored energy during peak demand times when electricity costs are high, which ultimately helps reduce your electric bill and save some money. In the case of a power outage, PWRcell is ready to supply backup power to your home.

This allows you to:

• Capture and store power from solar panels for extended durations. You can get through the night on stored solar.
• Protect what’s important – your home and family – during power outages.
• Utilize stored electricity during peak demand, grid outage or when electricity costs are high, thus incurring lower energy bills and avoiding peak rates.
• Gain greater independence from the grid.
