What are Differences Between Load Management Systems?

Types of Load Management Systems

Load management systems can be categorized into two primary types: centralized and decentralized systems. Centralized systems use a single controller to manage all loads, while decentralized systems use individual controllers for each load. For example, a centralized system may use a single smart switch to manage a home’s entire electrical load, while a decentralized system would use individual smart switches for each room.

Priority-Based Load Management

One popular approach to load management is priority-based load management. In this system, loads are categorized into critical and non-critical groups, with critical loads (such as lights and refrigeration) taking priority over non-critical loads (such as televisions and computers). For example, a load management system may automatically start a generator when the battery voltage drops below 50% to ensure the critical loads remain online. Non-critical loads, on the other hand, may be shed or reduced in power to conserve energy and extend battery life.

Generator Auto-Start and Smart Switch Techniques

Generator auto-start systems can be integrated with load management systems to automatically start the generator when the battery voltage drops below a certain threshold. This can be achieved through smart switches that monitor the battery voltage and send a signal to the generator when it’s time to start. Techniques such as voltage-based shedding, where non-critical loads are shed when the voltage drops below a certain threshold, can also be used to optimize energy usage and extend battery life. For example, a system may shed 20% of non-critical loads when the voltage drops below 12 volts, reducing the load on the battery and minimizing the risk of a deep discharge.
