A 120 kW, 180 kW or 240 kW charger describes equipment power capacity. It does not tell you how long every vehicle will charge or whether the site can support that output. For a commercial project, compare the operating scenario and available electrical infrastructure before choosing a rating.
What the three ratings change
| Power class | Question to ask | Project implication |
|---|---|---|
| 120 kW | Can the target vehicles receive the required energy within their normal dwell window? | May suit a site with moderate energy demand or longer stops, subject to site review. |
| 180 kW | Do shorter stops or overlapping sessions justify more available power? | Requires a closer look at peak demand and the intended connector behavior. |
| 240 kW | Can vehicles use the additional output, and can the site supply it? | Electrical design, peak demand and utilization become especially important. |
The rows are decision prompts, not promised charging times or site sizing rules. NX.SOLAR lists Titan V3 dual-CCS2 configurations at 120 and 180 kW, and Titan V4 dual-CCS2 configurations at 240 and 320 kW. Connector and certification coverage differs by configuration and market. Check the current Titan product information.
Use energy per visit to test the choice
Begin with the energy a typical vehicle needs during a stop, its usable charging window and the number of simultaneous sessions. As a simple illustration, delivering 60 kWh over a one-hour window implies an average of 60 kW delivered to that vehicle. Real sessions include vehicle power limits, a changing charge curve, losses and operating interruptions, so this arithmetic is only a first-pass planning check.
Next, examine the busy hour rather than a single vehicle. A two-connector site should ask how available output is allocated while both vehicles charge. A fleet depot should also consider which vehicles must depart first. The requested charger rating, number of connectors and site supply need to work as one plan.
When to consider a different architecture
If the site has many charging bays, complex vehicle circulation or phased growth, compare an integrated charger layout with a centralized power cabinet and remote terminals. The Nova split charging system is a separate architecture; its 360, 480 and 720 kW figures refer to cabinet options, not to each terminal.
What to send with an inquiry
- Installation country and required connector standard
- Vehicle types, expected energy per visit and dwell windows
- Peak simultaneous charging demand and number of bays
- Known site electrical capacity and any planned expansion
- Backend, payment, networking and project schedule
Next step: Review Titan configurations and submit a project inquiry with the information available. The exact model and compliance documents should be confirmed in the quotation.
