generator load shedding

Residential generators commonly employ three load shedding methods, with under frequency being the most prevalent. Intelligent load shedding, as the secondary method, allows for controlled activation and deactivation of loads based on continuous monitoring of the generator’s available capacity. Alternatively, load dropping involves locking out loads during generator operation. Under frequency load shedding, widely adopted due to its association with market-dominant manufacturers, is particularly used for air cooled generators. This approach induces overload conditions (reduced frequency) before eliminating loads, albeit indiscriminately affecting all connected loads involved in the shedding scheme. While intelligent load shedding is acknowledged as more advantageous for both the generator and end user experience, the under frequency method is favored for its cost-effectiveness and suitability for installation by technicians with lower skill levels. Ultimately, the choice hinges on cost considerations and the end user’s tolerance for circuit disruptions.
