Estimate overload shutdown time from nominal power, current load, ambient temperature, and manufacturer overload curves.
Sustained AC output demand
Cabinet / install site air temp
Manufacturer-style overload time curve
122.2% of derated 2,700 W · Standard off-grid (generic)
Warning: short overload window
Brief overload only — not suitable for continuous operation at this load.
Derated nominal
90% of nameplate at 35°C

Y-axis: allowed run time (log scale, capped at 120 min for display). Amber dot = your current operating point.
Allowed run duration at common overload levels (derated nominal basis).
| 100% load (2,700 W) | Continuous |
|---|---|
| 110% load (2,970 W) | 60 min |
| 120% load (3,240 W) | 10 min |
