What Is a Microgrid?
Most homes and businesses get electricity from one place — the utility company. When that connection is interrupted, the power goes out. A microgrid takes a different approach. It gives your property its own local energy sources that work together automatically, so you are not relying on a single point of failure.
In Plain English
Think of basic solar like a garden hose — water flows when the tap is on, but stops the moment it is turned off. A microgrid is like having a hose, a storage tank, and a backup pump all connected together. You have water whenever you need it, rain or shine.
Why a Microgrid Is More Than Just Solar
Basic solar panels generate electricity when the sun is shining, but they typically shut off when the utility grid goes down — even on a sunny day. A microgrid adds battery storage and a smart energy manager so your property can keep running on its own power during an outage. The system decides automatically where electricity should come from and where it should go, moment by moment.
Depending on the system design, a microgrid may use:
Onsite Solar
Panels generate electricity during daylight hours.
Battery Storage
Stores extra energy for use when the sun is not shining.
Utility Power
The grid stays available as a supplement or backup.
Optional Generator
Provides extended runtime during long outages.
These energy sources work together automatically to provide reliable electricity — whether the utility grid is available or not.
The Four Parts of a Modern Microgrid
Every microgrid combines generation, storage, intelligent management, and delivery — working together as one system.
Onsite Generation
Solar panels generate electricity during daylight hours, providing a renewable source of power for your property.
Battery Storage
Extra energy is stored for later use — at night, during outages, or when demand is high.
Smart Energy Manager
An advanced controller continuously decides where electricity should come from and where it should go. This process is fully automatic.
Your Home or Business
Electricity is delivered where it is needed — protecting essential circuits or an entire property, depending on your engineered system design.

Smart Energy Manager
The brain of the system. It constantly decides where your electricity should come from and where it should go — all automatically, in real time.
During Everyday Operation
The smart energy manager automatically balances power between solar production, stored battery energy, and the utility grid to maximize efficiency and reduce the amount of electricity you need to buy.
When the sun is shining and your property is using less than the panels are producing, the extra energy is stored in the battery or sent back to the grid. When your property needs more than the panels are producing, the system draws from the battery or the utility — automatically.
When the Grid Goes Down
The smart energy manager detects the outage and automatically disconnects your property from the grid. Your property continues running on available onsite resources — solar during the day, battery storage at night, and an optional generator for extended outages.
The transition is automatic. There is no switch to flip and no generator to start manually. What stays powered depends on your engineered system design — from essential circuits to your entire property.

Why Property Owners Choose Microgrids
A microgrid provides resilience and flexibility that a traditional solar installation alone cannot.
Energy Independence
Generate and store your own electricity instead of relying entirely on the utility company.
Backup Power
Keep critical loads running automatically when the grid fails.
Storm Resilience
Designed to weather outages with battery storage and solar recharging.
Lower Utility Dependence
Reduce the electricity you purchase from the utility over time.
Business Continuity
Keep operations running during outages that would otherwise halt business.
Protection for Critical Equipment
Maintain power for refrigeration, medical devices, and sensitive electronics.
Future Expansion
Add battery capacity, solar, or a generator as your needs grow.
Long-Term Flexibility
Adapt to changing utility rates, technology, and energy goals over time.
Traditional Solar vs. Microgrid
A microgrid builds on solar by adding storage, intelligence, and resilience.
Traditional Solar
Solar panels that reduce your electric bill but typically stop working when the grid goes down.
- Generates electricity during the day
- Reduces your monthly electric bill
- Typically shuts off when the grid goes down
- No built-in energy storage
- Limited or no backup capability
Microgrid
Solar, battery storage, and smart energy management that keep your property powered — even during outages.
- Generates electricity during the day
- Stores energy in a battery for later use
- Manages power automatically and in real time
- Can continue running during outages when properly designed
- Can expand over time as your needs grow
- Provides greater energy resilience
