Peak Load Analyzer
Estimate **peak running** and **starting surge** load with diversity/simultaneity. Great for selecting inverter/generator sizes and main breaker limits.
Scenario & Assumptions
Sets a default simultaneity for non-critical loads. You can override per row.
Everything On = 100%. Typical ≈ 50–70%. P90 ≈ 70–85%.
What % of running load is likely to be “present” at the instant big motors start.
Tip: Mark truly essential items as Critical. They’ll use 100% simultaneity regardless of scenario.
Loads
| Name | Watts | Qty | Surge× | Simult. % | Critical | kW eff. | |
|---|---|---|---|---|---|---|---|
Surge× is starting multiplier vs running watts (e.g., fridge 3–6×, AC 4–7×). If “Simult. %” blank, we apply the scenario/global setting unless marked Critical.

This page accepts L (base64 of [name, W, hours/day]) from other SolarVsGrid tools. We set Qty=1, Surge×=3 (guess), and Simult. %=min(100, hours/24×100).
