Data Methodology
Data Sources
All specifications are sourced from official manufacturer documentation: product pages, user manuals, and specification sheets. We do not use retailer listings or third-party databases as primary sources.
Runtime Calculation
runtime_hours = (capacity_wh × 0.85) ÷ appliance_watts
85% inverter efficiency is a conservative real-world estimate. Actual runtime varies with temperature, battery age, and load.
Solar Charging Calculation
effective_watts = min(panel_watts × panels × 0.80, station_max_solar)
charge_time = (capacity_wh × 0.80) ÷ effective_watts
charge_time = (capacity_wh × 0.80) ÷ effective_watts
80% panel derate accounts for real-world losses vs STC rating. Charging calculated to 80% capacity — the practical usable estimate.
Verification
Every spec has a verification status. Unverified values are excluded from all calculations and never shown as confirmed data.
