Koolbridge Energy – Smart Load Center General FAQ
General FAQ
1. General Overview
What is the Koolbridge Smart Load Center (SLC)?
The Koolbridge Smart Load Center (SLC) is a next-generation intelligent electrical panel that replaces the traditional breaker box. It actively manages how energy flows to each circuit in a home, dynamically selecting the most cost-effective and reliable power source from utility, solar, battery, and/or generator.
What problem does Koolbridge solve?
Traditional breaker panels are passive and cannot manage energy usage, reduce peak demand, optimize solar or battery systems, or provide intelligent backup control. Koolbridge solves this by providing circuit-level monitoring, automation, and dynamic energy source switching, enabling cost savings, improved resilience, and energy independence.
How is Koolbridge different from other smart panels?
Koolbridge uses a patented dual-bus architecture that allows simultaneous use of two energy sources and source selection on every individual circuit. Competing smart panels typically rely on fixed source assignments or external transfer switches and cannot dynamically switch energy sources per circuit.
What is the dual-bus architecture?
The dual-bus design allows two independent 240V AC power feeds to power the panel simultaneously. Each circuit can independently select which bus to draw power from, enabling seamless switching between grid, solar, battery, and generator sources.

3. Energy Management & Operation
How does the Smart Load Center manage power?
The SLC continuously monitors power consumption at each circuit. Using embedded intelligence, it dynamically routes energy from the most optimal source (utility, solar, battery, or generator) to each circuit in real time.
How does the SLC reduce electricity costs?
The SLC lowers costs by:
- Maximizing use of solar energy
- Prioritizing battery usage during peak utility pricing
- Reducing grid usage during Time-of-Use (TOU) periods
- Preventing unnecessary grid imports
What is Time-of-Use (TOU) optimization?
During peak pricing periods, the SLC automatically shifts loads to solar and/or battery power to avoid high utility rates, reducing monthly bills.
How does load shedding work?
During outages or grid constraints, the SLC can automatically shed (turn off) non-critical loads, preserving battery capacity for essential circuits.
What happens during a grid outage?
By design, the SLC isolates the grid (Primary Bus) from alternate sources (Secondary Bus) and during a grid outage the SLC continues supplying critical loads using solar and battery systems via its Secondary Bus. When grid is restored, it can stagger load restart to prevent surges and extend battery runtime.
Can the SLC operate without grid connection?
Yes. The Koolbridge SLC architecture supports “no utility interconnect” solar systems, allowing homeowners to self-consume solar power even before/without utility approval. Check with your local utility and AHJ.
4. Backup Power & Resilience
How does Koolbridge improve backup performance?
By managing energy at the circuit level, Koolbridge SLCs ensure:
- Extended battery runtime
- Priority power delivery to critical circuits
- Automatic load shedding
- Smarter generator integration
Does Koolbridge require an external automatic transfer switch (ATS)?
No. Koolbridge eliminates the need for a traditional ATS by performing source switching internally at the circuit level. In effect every circuit has its own independent ATS.
Can Koolbridge work with generators?
Yes. The Koolbridge SLC seamlessly integrates with backup generators and dynamically manages load priorities. Instead of wiring a Critical Loads panel with some subset of the homes loads, the SLC becomes a dynamic, configurable critical loads panel.
5. Solar, Battery, and EV Integration
How does Koolbridge integrate with solar?
The SLC dynamically prioritizes solar energy usage, maximizing on-site generation consumption and minimizing grid dependency.
Does Koolbridge improve solar ROI?
Yes. By increasing solar self-consumption and reducing exported energy, Koolbridge allows homeowners to right-size their PV installation and by doing so significantly improves solar return on investment.
How does Koolbridge enhance battery lifespan?
By controlling discharge rates and avoiding deep discharge cycles, the SLC helps extend battery life and improve long-term performance. As with PV, we allow the homeowner to right-size their battery installation so that they only install as much battery capacity as needed.
Can Koolbridge manage EV chargers?
Yes. EV chargers can be treated as managed loads, allowing dynamic control based on grid conditions, TOU pricing, and backup availability. E.g. during a grid outage you might not want your EV charger to be operational as it can quickly drain available battery storage, but instead allow it to be used only during peak solar production times.
6. Installation & Compatibility
Is Koolbridge compatible with existing homes?
Yes. Koolbridge supports both new construction and retrofit installations. Licensed and certified installers can remove existing panels and replace with Koolbridge panels.
Does Koolbridge simplify panel upgrades?
Yes. The SLC simplifies service upgrades by optimizing available capacity, often eliminating the need for costly service increases.
Is Koolbridge difficult to install?
No. Koolbridge is designed for electricians to install similarly to traditional panels using standard breakers and wiring practices.
Does Koolbridge require special training to install?
Installers are required to participate in the Koolbridge Certified Installer Program for training, certification, and technical support.
7. Electrical Code & Compliance

14. Common Customer Questions
Can Koolbridge really lower my electric bill?
Yes. Most homeowners see savings from TOU optimization, increased solar usage, and reduced grid reliance.
Will my lights flicker during switching or will heavy load appliances like microwaves or dryers stop working?
No. Switching occurs at the circuit level and is seamless due to fast switching times.
Can I monitor usage per circuit?
Yes. Circuit-level monitoring provides detailed insight into home energy consumption. Data can be shown.
How do I define which critical loads should be prioritized during a grid outage?
The Homeowner Management App, allows homeowners to specify the importance of every circuit in their home into 3 categories:
- Need to Have
- Like to Have
- Don’t Care
During a grid outage the SLC will automatically shed low priority loads from the Don’t Care category, and then systematically shed the lowest priority loads based on available production from Solar/Battery or Generator.
During an outage the homeowner can always use the app to manually re-prioritize specific loads (circuits) and the SLC will act accordingly.
