VEHEMENT buyer guide
Rated vs maximum generator output: compare the right figures
Use model-specific rated and maximum output figures when comparing VEHEMENT inverter generators.
Generator model numbers, rated output and maximum output describe different things. Compare the stated output specifications rather than estimating capacity from the digits in a model name.
Examples from the current VEHEMENT model list
| Model | Rated output | Maximum output |
|---|---|---|
| VM4500IO | 4 kW | 5 kW |
| VM6000i-VA/VB | 4 kW | 4.5 kW |
What to request for an application
Provide the intended loads and their running and starting requirements. Check the generator's voltage, frequency, phase and connection requirements, together with the output figures. Ask for the model documentation to confirm operating conditions and any permitted maximum-output duration.
Keep quotations comparable
Record the exact model, version and configuration with both output figures. Comparing one supplier's maximum output with another model's rated output can give a misleading comparison.

Use the full model list to build your shortlist
The current inverter catalogue covers 1–12 kW rated output across enclosed and open-frame ranges. VM3500IO is rated at 3 kW, VM6000i-VA/VB at 4 kW and VM14000I-OPEN at 12 kW. Compare the rated column, then check maximum output and electrical configuration separately.
