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 UI	Parameter	Value	Set on	Info
# Load Management > Dynamic Solar Charging	Configure Solar Mode for DLM	PV Surplus	DLM Master	Charges only with solar power.
# Load Management > DLM External Measurement	External Meter Location	Renewable Production	DLM Master	Sets meter at the solar panel connection.
# Load Management > Dynamic Solar Charging	Use solar mode on this charger	On	All Charging Stations	Marks 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 UI	Parameter	Value	Set on	Info
# Load Management > Dynamic Solar Charging	Configure Solar Mode for DLM	PV Surplus + Grid Support	DLM Master	Allows limited grid use.
# Load Management > Dynamic Solar Charging	Use phase switching relay (1ph <> 3ph)	On	DLM Master	Enables switching between phases.
# Load Management > Dynamic Solar Charging	Use solar mode on this charger	On	All Charging Stations	Enables 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
