VEHEMENT buyer guide
Open-frame vs enclosed inverter generators for importers
Compare VEHEMENT open-frame and enclosed inverter generator ranges using model specifications and procurement requirements.
Choose between open-frame and enclosed inverter models using the target configuration, power requirement and distribution plan. The housing style alone does not establish the noise level, runtime or suitability for a particular load.
Compare the two product ranges
| Question | Open-frame inverter range | Enclosed VA/VB range |
|---|---|---|
| Current rated-output range | 3–12 kW | 1–4 kW |
| Versions to confirm | Electrical configuration, start system and model | VA/VB version, electrical configuration and start system |
| Procurement details | Dimensions, weight, packing and available accessories | Dimensions, weight, packing and available accessories |
Ask for comparable performance evidence
For noise comparisons, request the measurement method, distance and operating load. For runtime, request the load and fuel quantity used. For output quality, request model-specific test conditions and results. Avoid comparing numbers measured under different conditions.
Plan branding and after-sales support
Confirm which colours, labels, panels and packaging options are available for the chosen model. Agree MOQ, production lead time, warranty terms and spare-parts support during quotation.
Open-frame inverter specifications · Enclosed inverter specifications
A model-level comparison at 4 kW rated output
| Specification | VM4500IO | VM6000i-VA/VB |
|---|---|---|
| Housing | Open frame | Enclosed VA/VB |
| Rated output | 4 kW | 4 kW |
| Maximum output | 5 kW | 4.5 kW |
| Voltage / frequency | 220 V or 230 V; 50 Hz or 60 Hz; catalogue also lists 120 V / 60 Hz | 220 V or 230 V; 50 Hz or 60 Hz; catalogue also lists 110 V / 60 Hz |
| Starting system | Recoil standard; electric / remote optional | Recoil standard; electric / remote optional |
| Fuel tank | 10L | 7L |
| N.W. / G.W. (recoil) | To be confirmed | 23/25 kg* |
| Machine L × W × H | To be confirmed | VA 515 × 320 × 495 mm; VB 500 × 300 × 470 mm |
| Carton L × W × H | To be confirmed | VA 530 × 335 × 510 mm; VB 515 × 315 × 485 mm |
Both catalogue entries list 4 kW rated output. The VM4500IO lists 5 kW maximum output, while the VM6000i-VA/VB lists 4.5 kW maximum output. Compare the rated figures first; a higher maximum figure is not a higher continuous-output rating.
Both have recoil starting as standard, with electric and remote starting optional. The two fuel-tank sizes do not establish a runtime comparison. Request comparable noise, runtime and output-quality test data before choosing on those criteria.
* N.W. / G.W. means net weight / gross weight. Enclosed weights apply to the recoil-start version and are the same for VA and VB. VA/VB differ only in housing; their other technical specifications are the same. Optional equipment can change the final weight. Open-frame weights are not yet listed. Carton dimensions add 15 mm to each machine dimension.
