Solar DLM Case Studies

This section provides detailed case studies for Solar Dynamic Load Management (Solar DLM), with multiple configuration examples of increasing complexity.

1. Solar-Powered Office Charging​

1.1. Scenario​

An office building has 10 EV chargers powered by solar panels. Charging should only use solar energy when possible and avoid drawing power from the grid.

1.2. How Solar DLM Helps​

  • Only allows charging when solar energy is available.
  • If there's no solar energy, charging pauses instead of using grid power.

1.3. Configuration Example​

Location in Config UIParameterValueSet onInfo
Load Management > Dynamic Solar ChargingConfigure Solar Mode for DLMPV SurplusDLM MasterCharges only with solar power.
Load Management > DLM External MeasurementExternal Meter LocationRenewable ProductionDLM MasterSets meter at the solar panel connection.
Load Management > Dynamic Solar ChargingUse solar mode on this chargerOnAll Charging StationsMarks these chargers as solar-aware.

2. Mixed Solar and Grid Charging with Phase Switching​

2.1. Scenario​

A charging station has 20 EV chargers powered by both solar panels and the grid. The system should use solar energy first but allow grid support when needed. It should also switch between single-phase and three-phase charging based on solar availability.

2.2. How Solar DLM Helps​

  • Uses solar energy first, but allows grid power when solar is insufficient.
  • Switches between 1-phase and 3-phase charging to maximize efficiency.

2.3. Configuration Example​

Location in Config UIParameterValueSet onInfo
Load Management > Dynamic Solar ChargingConfigure Solar Mode for DLMPV Surplus + Grid SupportDLM MasterAllows limited grid use.
Load Management > Dynamic Solar ChargingUse phase switching relay (1ph <> 3ph)OnDLM MasterEnables switching between phases.
Load Management > Dynamic Solar ChargingUse solar mode on this chargerOnAll Charging StationsEnables participation in solar charging.

3. Implementation Considerations​

When implementing Solar DLM solutions:

  • Ensure proper placement and configuration of the energy meter
  • Consider seasonal variations in solar production
  • Plan for fallback scenarios during extended periods of low solar production
  • Test the system during different weather conditions to verify proper operation
  • Monitor the system's performance to optimize settings based on actual usage patterns
