How to Assess the Effectiveness of Your Load Management Strategy?

Tracking Key Performance Indicators (KPIs)

To evaluate the effectiveness of your load management strategy, track the following KPIs:

• Average daily energy usage in watt-hours (Wh) or kilowatt-hours (kWh)
• Generator runtime in hours per day
• Battery depth of discharge (DOD) as a percentage
• Load management strategy compliance as a percentage of total load hours

For example, if your system is designed to manage 10 critical loads and 5 non-critical loads, track the percentage of time each load category is operating within its designated priority level.

Implementing a Load Hierarchy

Establish a clear load hierarchy based on priority:

1. Critical loads (e.g., medical equipment, lighting, refrigerator)
2. High-priority loads (e.g., water pumps, communication equipment)
3. Medium-priority loads (e.g., computers, TVs, kitchen appliances)
4. Low-priority loads (e.g., non-essential lighting, entertainment systems)

Use smart switches or load controllers to automate load prioritization and switching.

Generator Auto-Start and Load Management

Configure your generator to auto-start based on battery state of charge (SOC) and load priority:

• Set the SOC trigger level at 20-30% (e.g., 20.5% SOC)
• Set the load priority threshold at 50% (e.g., 50% of critical loads operating)
• Configure the generator to start automatically when the SOC falls below the trigger level and/or when the load priority threshold is exceeded

This ensures that critical loads are protected and the generator starts when necessary to maintain system stability.
