List your loads
Write down every device and its continuous watts.
Side by side · Load before capacity
Compare what actually matters.
Start with output for device compatibility. Then use capacity to estimate how long the system can keep those loads running.
Modular systems
G Series comparison
Pro and Ultra models add independent 3.3kW inverter channels. Their listed total output is distributed across those channels, not available through one unrestricted outlet.

Runtime planning
Capacity × 0.85
÷ device watts
Use 85% as a simple planning factor for conversion losses. A 1,152Wh P1200 running a steady 60W load is roughly:
1,152 × 0.85 ÷ 60 ≈ 16.3 hoursThis is an estimate, not a guarantee. Real runtime changes with temperature, battery condition, surge, device cycling and simultaneous loads.Find the highest draw
Choose output above the combined load and account for startup surge.
Estimate runtime
Use watt-hours only after you know the station can power the devices.
Add solar if needed
Solar extends a trip but depends on real weather and panel position.
