Solar Battery Sizing Calculator vs Solar Inverter Sizing Calculator
Two calculators for the same neighbourhood of questions. Here is what each measures, what you feed in, and where you'd reach for one over the other.
Solar Battery Sizing Calculator
Find the minimum battery bank capacity needed to power your home through cloudy days or outages. Use this when designing an off-grid or hybrid solar system and choosing between lithium or lead-acid batteries.
- Answers
- Required Battery Capacity (Ah)
- Inputs
- Daily Energy Usage, Backup Days Needed, Battery Type, System Voltage, System Efficiency
Solar Inverter Sizing Calculator
Determines the right inverter size for a solar array by factoring in panel capacity, orientation, climate, and DC:AC ratio. Use this when designing or auditing a rooftop or ground-mount solar system.
- Answers
- Recommended Inverter Size (W AC)
- Inputs
- Total Panel Capacity, Panel Orientation Mix, Climate Factor, Desired DC:AC Ratio
