## What is SunRig?

Stop guessing if your solar will keep up with your power draw. SunRig shows you exactly how your battery state of charge changes hour by hour — based on your rig setup and real-time weather at your location.

Every boondocker knows the frustration: you check your battery monitor in the morning, but you still don't know if your solar will cover today's load — or how many more days you can stay before you need to move camp.

HOW IT WORKS
1. Enter your rig: solar panel wattage, battery capacity and type (LiFePO4, AGM, or GEL), inverter efficiency, and your appliance list.
2. SunRig fetches hourly solar irradiance, temperature, and cloud cover for your location.
3. You get a Power Score (0–100), a sunset SOC estimate, and hour-by-hour power balance for the day.

It takes 2 minutes to set up. No account required.

TODAY'S POWER SCORE
See your daily solar-to-load ratio at a glance. Green means your solar covers your draw. Yellow means it's close. Red means your battery is draining.

HOURLY POWER TIMELINE
See when solar surplus flows in and when your battery drains — hour by hour across the day. Know exactly when your heaviest draw happens.

APPLIANCE TRACKER
Add your fridge, lights, laptop, A/C, and other loads with wattage and daily hours. SunRig accounts for always-on parasitic draws like CO detectors and refrigerator duty cycles.

PRO FEATURES
Upgrade to Pro for deeper insights:
- 7-day SOC curve: see hour-by-hour battery level across 168 hours
- MOVE Alert: get warned before your SOC drops below 20%
- What-If simulator: toggle appliances on/off and see how your SOC curve changes
- Storage Mode: track battery self-discharge during winter storage and get charge reminders
- Trip Planner: simulate power balance at your next destination before you go
- Upgrade Simulator: compare your current rig vs an upgraded setup side by side
- Multiple rig profiles and unlimited appliances
- SOC threshold notifications

PRIVACY FIRST
All rig data and appliance settings are stored locally on your device. No account, no tracking, no ads. Location is used only to fetch weather data from a public API. Your coordinates are never stored on any server.

SunRig is an estimation tool for RV solar power planning. Actual solar production and battery behavior depend on panel condition, shading, tilt, wiring losses, battery age, and other factors not fully modeled. Always monitor your battery with a dedicated battery monitor. This app does not replace manufacturer guidelines or professional electrical advice.
