How the Blue Surge Energy Ecosystem Works
This isn't simply a battery connected to your house. It's an energy system designed to automatically use the best available power source.
During normal operation, solar can power the home and charge the batteries. After sunset, the home can operate from stored battery energy, with the utility grid available if additional power is needed.
During a grid outage, solar and batteries continue supporting the home. If battery charge eventually drops to a programmed level, a properly integrated generator can start automatically, support the home and replenish the batteries. Once the batteries reach the desired charge level, the generator can shut back down and the home returns to battery operation.
Your Generator Should Be the Backup to Your Backup
Run the house. Recharge the batteries. Shut the generator back off.
Traditional generator backup can mean running an engine continuously throughout an extended outage. An integrated battery-and-generator system provides another approach.
Your batteries can carry the home when stored energy is available. If the batteries get low and solar production isn't enough, the generator can step in, support the home's electrical loads and recharge the battery bank.
Once the batteries reach their target charge level, the generator can shut back down.
The generator runs when you need it — not necessarily 24/7.
Generator runtime varies based on home loads, battery capacity, generator size, solar production and system settings.
Four Energy Sources. One Coordinated System.
☀️ Solar — Your Primary Energy Producer
During daylight hours, solar can supply the home while using available excess production to recharge battery storage.
🔋 Batteries — Stored Energy When Solar Isn't Available
After sunset or during periods of lower solar production, the home can operate from energy stored during the day.
⚡ Utility Grid — Everyday Backup
When the grid is available, it can fill the gap if household demand exceeds the available solar and battery capacity.
⛽ Generator — Extended-Outage Support
When the grid is unavailable and battery storage becomes depleted, a compatible generator can provide another energy source and replenish the batteries.
Instead of four unrelated pieces of equipment, Blue Surge designs them to work together as one energy system.
You Don't Need New Solar to Add Battery Backup
Battery + Grid
Backup power for homeowners who aren't ready to add solar.
Existing Solar + Battery
Add energy storage and backup capability to a qualifying existing solar system.
New Solar + Battery
Design your ground-mounted solar and battery system together from the beginning.
Solar + Battery + Generator
Create the complete energy ecosystem for everyday energy management and extended outages.
How Much of Your Home Do You Want to Back Up?
Essential-Load Backup
Prioritize the things that matter most:
Refrigerators and freezers, lighting, internet, well pumps, selected receptacles, garage equipment and other important circuits.
Whole-Home Backup
For homeowners wanting greater backup capability, Blue Surge can evaluate HVAC equipment, appliances, water heating, well pumps, lighting, receptacles and other major household loads.
“Whole-home backup” doesn't necessarily mean every electrical appliance operates simultaneously without limits. Proper inverter sizing, battery capacity and load management are critical to designing a system that performs the way you expect.
The EG4 Energy Ecosystem
A flexible platform for solar, batteries and generator integration
For many Blue Surge projects, we use the EG4 GridBOSS and FlexBOSS platform to integrate utility power, battery storage, solar production and compatible generator backup.
Depending on the project, the system can be designed around:
- GridBOSS energy management
- FlexBOSS hybrid inverter technology
- Modular battery storage
- New or existing solar
- Generator integration
- Whole-home or selected-load backup
The equipment is only part of the system.
How the inverter, batteries, generator, solar, electrical service and household loads are designed to work together is just as important as the equipment itself.
What Happens When the Grid Disappears?
Ideally, very little.
Your solar, batteries and generator can be designed to work together automatically so your home can continue operating through short outages and extended emergencies.
- Solar produces it.
- Batteries store it.
- The generator extends it.
- Blue Surge brings it together.
