Energy independence
Battery systems
When the power goes out, be ready. A grid-hybrid system keeps your essentials running on stored solar energy.
Grid-hybrid systems
Independence from the grid
A standard grid-tied system needs a working utility grid to operate. A fully off-grid system runs on its own with batteries and often a generator.
A grid-hybrid system gives you both: the savings of grid-tied solar every day, and battery backup when the utility goes down. Battery backup needs no fossil fuel, so it is a quiet, clean alternative to a generator.
What it protects
Protect what matters most
Choose whole-home backup or protect only the loads you rely on most.
-
Your whole home
Size the system to keep every circuit powered.
-
Internet and work
Stay connected when you need it most.
-
Security system
Keep alarms and cameras running.
-
Fridge and freezer
Protect your food through longer outages.
Compare options
Select the right system for you
Grid-tied, backup and off-grid systems each fit different goals and budgets.
-
Grid-tied
Relative cost: $
- Works while the utility grid is running
- Solar energy is used onsite first, and extra energy earns bill credits
- Panels shut down during outages to protect line workers
- Simple design based on monthly energy use
-
Backup system
Relative cost: $$
- Powers selected loads from stored energy during an outage
- Small, medium or large systems to match your needs
- Batteries charge from the grid, solar or both
- Panels keep working while the grid is down
-
Off-grid
Relative cost: $$$
- No reliance on the grid, though it can be used if present
- Full functionality regardless of grid conditions
- Careful inverter and battery design, usually with a standby generator
FAQ
Battery questions
Batteries charged by solar may qualify for federal incentives under current rules. Please check with your tax advisor.
It is how many days your system can run your chosen loads without recharging from solar. More days means more freedom and more storage.
Lithium iron phosphate and sealed lead-acid batteries need no routine maintenance. Flooded lead-acid batteries need regular checks and equalization charging.
It depends on your needs. We complete a detailed load analysis and show you pricing and performance for each capacity option.
