Frequently Asked Questions
What is DIM Mode and how does it work?
DIM Mode allows you to configure intelligent dimming schedules. The light operates at full brightness for an initial period, then switches to a reduced brightness level (30%-70%) for the remainder of the night, and returns to full brightness before dawn.
How does DOD (Depth of Discharge) affect calculations?
DOD limits how much of the battery capacity can be used. Lead Acid batteries typically have a 60% DOD limit to extend lifespan, while Lithium batteries can safely use up to 90%. The calculator adjusts the available energy based on your DOD setting.
What does the Energy Table show?
The Energy Table provides a detailed daily breakdown showing battery state before dawn, daily charging, battery state before evening, daily discharging, DOD limits, and actual available energy for each day of analysis.
Can I export the calculation results?
Yes, you can generate comprehensive PDF reports containing all calculation results, charts, and industry standards reference for documentation and project planning purposes.
