Load management refers to a system to optimize the use of power from a generator during an outage. This system manages the distribution of electrical loads to ensure critical appliances and systems have priority while preventing the generator from being overloaded. The product will turn on and off certain loads to make sure you don't overload or shut the generator off in outage. It allows you to use a smaller generator to save money and make back up power more affordable than sizing for the complete house running like on utility.
Real world effects of Load Management how you live
In the real world we don't use the AC or Range all day. So when you need to use the appliances or loads you should be able to use them but just not all at once. If one load comes on when you are using the other one it may delay the use of one or more loads. So the AC may be delayed until you are done using the Range and done cooking. In real life just think of how you live. If you want to live life with no delays you will need to size the generator bigger to accommodate this.

How does load management work?
Initial Response: Power Outage and Generator Start-Up
• Power Outage: A power outage occurs, and the Automatic Transfer Switch (ATS) detects the loss of utility power.
• Generator Activation: The ATS signals the generator to start. The generator begins supplying power to the home.
Warm-Up Phase (First 5 Minutes)
• Frequency and RPM Monitoring: The load management device monitors the generator’s frequency and engine RPM. It ensures that the generator stabilizes before adding significant loads.
• Delay of Large Loads: During the first five minutes, the load management system prevents large loads (like AC or electric range) from engaging.
• Prioritization of Critical Circuits: Only critical circuits are allowed to receive power initially. These include essential appliances like the refrigerator, medical equipment, and basic lighting.
Load Monitoring Phase (Post Warm-Up)
• Staged Engagement of Loads: After the initial five-minute warm-up, the load management system begins to allow larger loads to engage in a controlled manner.
• Timed Priority: Loads are brought online sequentially, based on their priority. For example, the HVAC system might be allowed to start before the electric range.
• Parameter Monitoring: The system continuously monitors the generator’s frequency and RPM. If these parameters remain stable, additional loads can be engaged.
Load Shed Section (Overload Management)
• Detection of Overload: If the total load exceeds the generator’s capacity, the load management system will start shedding (turning off) non-essential loads.
• Priority-Based Load Shedding: The system prioritizes which loads to shed first. Less critical loads are shed before more essential ones.
• Retry Mechanism: After shedding a load, the system waits 5 to 6 minutes and then attempts to re-engage the load. If the generator can handle the load without frequency or RPM issues, it remains on.
Key aspects of load management:
Load Shedding:
The system can temporarily turn off non-essential loads to prioritize power for critical devices and prevent overloading the generator.
Load Prioritization :
The system can be programmed to prioritize which loads should receive power first, based on their importance to the household or facility.
Load Lockout :
Load lockout is a feature designed to prevent specific electrical loads from being powered by a generator during an outage.
