The Core Components of a Solar Generator Panels • Battery • Inverter • Charge Controller
Adjust the component sizes to see if your solar generator setup is balanced. Pick a scenario, tweak the numbers, and follow the checklist to understand what each part should do.
1. Choose a usage scenario
This will prefill typical loads and recommended sizing ranges.
2. Set your component sizes
Total wattage of all panels combined.
How much energy you can store.
How much AC load you can run at once.
Must handle panel current. This will auto-increase if panels exceed it.
3. Daily energy target
Example: a laptop (60 W for 4h = 240 Wh) + lights + phone charging.

Solar Generator Component Planner
The Solar Generator Component Planner is an interactive tool that helps you balance your solar setup by adjusting your panels, battery, inverter, and charge controller. It’s designed for off-grid enthusiasts, homeowners, and RV travelers who want to design efficient and reliable solar systems without guesswork.
How to use the Solar Generator Component Planner
This planner helps you design a balanced solar generator setup that includes four essential components: solar panels, a battery, an inverter, and a charge controller. The interface allows you to select a scenario and adjust each component to see how they interact and affect system balance.
Step 1: Choose your scenario
Start by selecting a usage scenario that best represents your solar setup. Options include Basic Camping, RV/VAN Life, Off-Grid Cabin, or Home Power Backup. Each scenario pre-fills recommended wattage, capacity, and usage settings to give you a realistic baseline.
Step 2: Adjust your components
- Solar Panels (W): Move the slider to increase or decrease your total panel wattage. More panels mean faster charging.
- Battery Capacity (Wh): Adjust the battery size to store more energy for nighttime or cloudy conditions.
- Inverter Size (W): Set your inverter power to handle the maximum AC load you expect to run.
- Charge Controller (A): The planner automatically suggests the right controller size to match your solar array.
Step 3: Set your daily energy target
Enter your estimated daily usage in watt-hours (Wh). The planner calculates how much energy your panels can produce and how much your battery can store, helping you determine if your setup meets your daily needs.
Step 4: Review your system balance
Once all inputs are set, the planner displays an instant status report showing whether your system is balanced, partially optimized, or underpowered. You’ll also see a checklist of recommendations for improving component compatibility.
Understanding the results
The Solar Generator Component Planner provides real-time feedback through a color-coded status indicator and a detailed checklist. These results help you understand how well your components work together.
- Green Status (Balanced): Your solar generator components are properly matched.
- Yellow Status (Needs Adjustment): One or two components may need resizing.
- Red Status (Unbalanced): Multiple mismatches could cause inefficiency or failure.
The tool also displays estimated daily energy production from your solar panels and battery storage levels. By analyzing these numbers, you can see if your solar array is large enough to recharge your batteries based on your target energy use.
Examples and scenarios
Example 1: RV or Van Life setup
For mobile solar users, select the RV/VAN Life scenario. You might use 400 watts of panels, a 1,800 Wh battery, a 1,200 W inverter, and a 30 A charge controller. This configuration supports medium appliances like a mini-fridge, lights, and small electronics.
Example 2: Off-Grid Cabin setup
Select Off-Grid Cabin (Full System) to simulate a permanent installation. A balanced system could include 1,200 W of panels, a 5,000 Wh battery, and a 3,000 W inverter. This provides enough power for lighting, refrigeration, and small tools.
Example 3: Home Power Backup
Choose Home Power Backup (Critical Loads) to plan emergency coverage. A system with 800 W of panels, 4,000 Wh of battery storage, and a 2,000 W inverter can keep essential devices running during outages.
Benefits of using this tool
- Visualize how solar generator components interact before purchasing equipment.
- Understand which component limits performance and where to upgrade.
- Prevent undersizing issues that can damage batteries or controllers.
- Plan energy-efficient systems tailored to your needs and environment.
- Experiment with configurations instantly without calculations or spreadsheets.
By using the Solar Generator Component Planner, you reduce the risk of imbalance and ensure every watt of energy is used efficiently. Whether you’re designing for off-grid living or backup power, this tool simplifies the planning process.
Common mistakes to avoid
- Ignoring controller limits: Your charge controller must support the maximum amperage generated by your panels.
- Underestimating inverter needs: A small inverter can cause overloads if you plug in high-demand devices.
- Using mismatched battery capacity: Oversized batteries without enough panel input will recharge too slowly.
- Skipping energy estimation: Always calculate your daily energy target to ensure realistic system performance.
- Neglecting system balance: Each component must complement the others for consistent power delivery.
