Battery Backup

  • Provides automatic backup during outages

  • Quiet operation with no fuel

  • Can help shift electricity use away from expensive time-of-use periods where applicable

  • Can pair with solar to store excess energy for later use

  • Best for homeowners who want seamless, everyday energy management plus outage protection

  • Limitation: runtime depends on battery capacity and how much of the home is being powered

Standby Generator

  • Designed for longer-duration outages

  • Can provide extended runtime as long as fuel is available

  • Often capable of supporting larger household loads

  • Automatically starts during an outage

  • Good fit for homeowners concerned about multi-day outages or extended grid failures

  • Limitation: requires fuel, maintenance, outdoor space, and produces noise/emissions

Battery + Solar

  • Start with dependable battery backup and add solar for daytime recharging and greater energy independence.

  • Provides automatic backup power during outages

  • Solar panels can recharge the battery during daylight hours

  • Stores excess solar energy for use at night or during higher-cost time-of-use periods

  • Can reduce reliance on utility electricity

  • Best for homeowners who want backup protection plus everyday energy savings

  • Limitation: performance and savings depend on sunlight, system size, energy use, and utility rate plan

Battery + Generator

  • Battery provides immediate, quiet backup

  • Generator can take over or recharge/support the system during extended outages

  • Gives the homeowner both short-term flexibility and long-duration resilience

  • Can reduce unnecessary generator runtime

  • Strong option for homeowners who want a more comprehensive backup strategy

  • Typically the highest-cost solution

Backup Power Isn’t Just About Outages

Battery systems may provide value even when the grid is operating normally. Depending on your utility rate plan and system configuration, a battery may help store lower-cost or solar-generated electricity and use it later during higher-cost time-of-use periods.

The right choice depends on what you want to keep powered, how long you want backup to last, your utility rates, available fuel, and your budget.
