Commercial Energy Logger

Uncover Hidden Electrical Problems

with Real-Time Power Monitoring

Sometimes, electrical issues aren’t obvious, but they’re costing you money, stressing your equipment, or tripping your breakers. That’s where an energy logger comes in.

At Bierlein-Trombley Electric, we use advanced energy data loggers to identify problems that can’t be seen with a standard meter. Whether you’re experiencing unexplained breaker trips, overloaded panels, high utility bills, or sensitive equipment shutdowns, our energy logger helps us track down the “why” behind the problem.

What Is an Energy Logger?

An energy logger is a device we connect to your electrical panel or circuits to monitor power usage over time, typically from 24 hours up to 2 weeks or more. It records data like:

  • Voltage levels and fluctuations
  • Current (amps) on each circuit
  • Power consumption (kWh)
  • Power factor and harmonics
  • Peak demand spikes


We use that data to identify patterns, diagnose overloads, and help you make informed decisions about upgrades or repairs.

Common Questions About Commercial Energy Logger

Q. When Should You Use an Energy Logger?

ANSWER: Customers typically call us for energy logging when:

  • Circuits or breakers are tripping, and no one knows why
  • Electric bills are high without a clear reason
  • Equipment is shutting down randomly
  • Lights flicker or dim when appliances turn on
  • A generator or backup power system is being sized
  • A service upgrade is being considered


In short, if there’s a mystery in your electrical system, the logger helps us solve it with hard data, not guesswork.

ANSWER: 

  • On-site assessment: We’ll look at the issue and determine where to connect the logger (main panel, subpanel, or specific circuits).
  • Install logger: We safely install the device and set the data recording period (typically 3–14 days).
  • Retrieve and analyze data: After the monitoring period, we retrieve the logger and use software to analyze trends.
  • Report and recommendations: You get a clear summary report and our expert recommendations to fix the issue or make improvements.

ANSWER: 

Service Estimated Cost Range
Basic 3-day monitoring & report $250 – $400
Extended monitoring (7–14 days) $400 – $750
Logger with in-depth load study $750 – $1,200+

Note: This cost is often credited toward a larger project if we proceed with an upgrade or repair based on the findings.

ANSWER: No. While commercial and industrial customers use this more often, residential homeowners with tricky power issues, like sensitive electronics or intermittent breaker trips, can benefit too.

ANSWER: Yes. In most cases, we can safely connect it while the system is live using proper PPE and tools. We’ll let you know if a shutdown is needed.

ANSWER: No. It’s completely passive, like a data recorder. It doesn’t interrupt or alter your power in any way.

ANSWER: Absolutely. That’s what sets Bierlein-Trombley Electric apart. We don’t just give you a spreadsheet, we give you real insight and a plan to move forward.

ANSWER:  

  • We own and operate professional-grade energy loggers, not cheap tools
  • Licensed electricians interpret the data, not software alone
  • Trusted by both homeowners and facility managers across Michigan
  • We serve Mid-Michigan and Traverse City with fast response times
  • No guesswork, just facts and smart next steps
