Issues with your whole-house generator frequently overloading during power outages are a common concern many homeowners face. Addressing it properly is essential to ensure your generator operates efficiently and reliably in the long term.
In this blog, we’ll explore the reasons behind generator overloads, the potential consequences, and the steps you should consider taking to resolve this issue. Whether you’re a generator owner seeking solutions or someone considering the purchase of a standby generator, understanding how to manage overloads is crucial for uninterrupted backup power when you need it most. Let’s dive into the world of generator overloads and find the solutions you need for a seamless power backup experience.
You’ll Have to Do a Little Detective Work.
If your whole house generator experiences an overload, it will be up to the homeowner to identify what may be causing it and what circuits can be turned off. The key to solving whole-house generator overload issues is shedding enough of the energy demand on the generator to prevent it from going into repeated shutdowns.
The solution involves checking which appliances were active on which circuits when the overload occurred, starting with those that consume the most energy. Using some basic troubleshooting, the homeowner should be able to narrow down the circuits with the most significant demand quickly and either shut them down or re-distribute those devices across other circuits. The problem often comes down to the homeowner running multiple heavy appliances simultaneously, such as air conditioners, heaters, or electric stoves, on a single circuit.
To resolve the issue, the homeowner can temporarily disconnect some of their higher-wattage appliances to reduce the demand on the generator. Once the load is within the generator’s capacity, the homeowner can restart it, and it should resume regular operation.
If overloads continue to occur regularly, especially under low demand, consulting with a licensed electrician or a Nick’s Generator technician will be necessary. They can assess the generator’s capacity, inspect the electrical connections, and ensure it is correctly sized for the home’s electrical load.
Professional guidance can help prevent future overloads and ensure the safe and reliable operation of the standby generator during power outages.
What Can Cause a Standby Generator to Go into Overload?
Excessive Demand
The most common cause of standby generator overload is simply connecting too many appliances or devices to the generator simultaneously, drawing more power than it can provide. Overloading can occur if you attempt to power heavy appliances like air conditioners, heaters, or electric stoves simultaneously. Be sure to check both breaker panels in the home and on the generator for any breakers in the “OFF” position or with a red indicator visible.
Short Circuits
Electrical faults, such as short circuits or damaged wiring in your home’s electrical system, can create sudden spikes in power demand and trigger overload protection on the generator.
Faulty Appliances
Some malfunctioning appliances or equipment may draw more power than they should, causing an overload when connected to the generator.
Generator Size
If the generator’s capacity is not appropriately matched to the electrical load required for your home, it may become overloaded quickly during high-demand situations.
To prevent overloads, it’s crucial to understand the generator’s capacity (rated in watts or kilowatts) and ensure that the total load connected to it does not exceed this capacity.
If overloads persist or you suspect electrical faults, it’s best to consult with a qualified electrician or generator technician to diagnose and resolve the issue safely.
How Do I Know if My Generator is Overloaded?
When your generator is being asked to provide more power than it can deliver, you’ll notice it when circuit breakers in your wall panel or on the generator begin to trip. Quite often, before the situation reaches a literal overload, your generator may exhibit sure signs that you’re asking it to do too much.
Dimming Lights
If your lights dim significantly when you turn on a high-wattage appliance, the generator may be struggling to meet the electrical demand.
Tripped Circuit Breakers
Frequent trips of circuit breakers in your electrical panel, especially when using multiple appliances, suggest that you’re pushing the generator beyond its capacity.
Generator Running Roughly
A generator running at uneven or erratic speeds may indicate it’s under excessive load. Unusual sounds or vibrations can accompany this.
Appliance Malfunctions
Overloaded generators can cause appliances to malfunction or operate erratically. Devices may shut off unexpectedly or show signs of reduced performance.
Generator Overheating
Overloading can cause a generator to overheat. If you notice excessive heat emanating from the generator or burning odors, it signifies potential trouble.
Flickering or Unstable Power
Frequent power fluctuations, including flashing lights and unstable electrical supply, are common when a generator is overloaded.
Reduced Voltage
If you have a voltmeter, you can measure the voltage output of the generator. It may indicate an overload if it consistently falls below the normal range.
Always be mindful of the electrical load you’re connecting to prevent overloading your standby generator. Avoid running multiple high-wattage appliances simultaneously, and consider an appropriately sized generator for your home’s needs to ensure reliable and safe operation.
What Can I Do to Prevent Overloading My Natural Gas Standby Generator?
Preventing the overloading of a whole-house generator is crucial to ensure its smooth and reliable operation during power outages. What can the homeowner do before installation and after the generator is online to ensure overloads aren’t a problem for their system?
Generator Sizing
Invest in an appropriately sized generator for your home’s electrical needs. A professional generator installer can analyze the load requirements of your home to determine the suitable generator capacity. Oversizing the generator provides a safety margin, while undersizing the unit increases the risk of overloading.
Professional Installation
Have your whole-house generator professionally installed by licensed technicians who understand local electrical codes and load management. They can ensure safe and code-compliant connections to your home’s electrical system.
Install a Quality Automatic Transfer Switch
Install an automatic transfer switch (ATS) to manage the electrical load by shedding non-essential circuits during an outage. ATS systems can prioritize critical loads and help prevent overloads.
Load Management
Prioritize your essential appliances and circuits during a power outage. Identify the critical items you need, such as refrigeration, heating or cooling, and lighting. You can avoid overwhelming the generator’s capacity by strategically managing your electrical load and turning off non-essential items.
Regular Maintenance
Ensure your generator is well-maintained with routine service checks. Clean or replace air and fuel filters, check, gap, or replace spark plugs, and conduct regular oil changes to keep the generator in optimal condition.
By following these preventive measures, homeowners can maintain the reliability of their whole-house generator while avoiding the risks associated with overloading, such as equipment damage and power disruptions during critical times.
