The Solar Inverter Loading Ratio (ILR) & DC Clipping Loss Sizer evaluates proportional ratios, geometric root metrics, and balance percentages for photovoltaic inverter capacity sizing.

### Mathematical Evaluation & Formulas The tool computes three direct output metrics from three numeric inputs (V1, V2, and V3): - Capacity Overload Ratio: Evaluates parameter 1 multiplied by parameter 2 divided by parameter 3 (minimum denominator 0.01): (V1 * V2) / max(0.01, V3) - Geometric Saturation Factor: Computes the square root of the two-parameter capacity product: sqrt(max(0, V1 * V2)) - Relative Sizing Percentage: Measures the proportion of parameter 1 across the combined baseline: min(100, max(0, (V1 / (V1 + V2)) * 100%))

Note on Inverter Capacity Sizing: Solar system designers frequently pair an oversized DC solar array with a smaller AC inverter (typical DC-to-AC ratio of 1.20 to 1.30). This design generates higher energy yield during morning and evening shoulders while accepting minor mid-day peak clipping. This interactive tool evaluates the three-variable proportional arithmetic defined above.

### Numerical Calculation Example Testing inverter parameters with V1 = 120 (DC array rating factor), V2 = 25 (thermal reference factor), and V3 = 8 (inverter threshold divisor): - Capacity Overload Ratio: (120 * 25) / 8 = 3000 / 8 = 375.00 - Geometric Saturation Factor: sqrt(120 * 25) = sqrt(3000) ≈ 54.77 - Relative Sizing Percentage: (120 / (120 + 25)) * 100% = (120 / 145) * 100% ≈ 82.76%
