The ZCS Azzurro 3PH 250KTL-HV-Z0 / 330KTL-HV-Z0 / 350KTL-HV-Z0 range is designed for energy conversion in medium- and large-scale commercial and industrial photovoltaic systems, where efficiency, reliability and flexibility in PV array configuration are key requirements.
The range is available in three rated AC power sizes: 250 kW, 330 kW and 350 kW, with typical DC power ratings of 300 kW, 390 kW and 420 kW respectively.
High DC-side flexibility
The inverters support a maximum input voltage of 1,500 V and operate over a wide MPPT voltage range from 500 to 1,500 V, with a full-load operating range from 860 to 1,300 V.
The configuration features 6 independent MPPTs on the 250 kW model and up to 8 MPPTs on the 330 and 350 kW versions, providing greater flexibility when designing PV arrays with multiple strings. The maximum input current per MPPT is 60 A.
Efficiency and reliability for high-power PV systems
The range achieves a maximum efficiency of up to 99%, helping maximise the conversion of energy generated by the photovoltaic array.
The IP66 protection rating makes the inverters suitable for outdoor installations and demanding environmental conditions. A forced-air cooling system with controlled fan speed supports reliable operation at the high power levels for which these inverters are designed.
Protection, diagnostics and monitoring
The ZCS Azzurro 3PH 250-350KTL-HV-Z0 inverters integrate AC- and DC-side surge protection devices and support firmware updates and diagnostic operations via USB.
The range can also be monitored through the ZCS Azzurro app and portal, allowing users to view energy production, consumption and the main operating parameters of the photovoltaic system.
Three power ratings for C&I photovoltaic projects
The range includes:
| Model | Rated AC power | Typical DC power |
| AZZURRO 3PH 250KTL-HV-Z0 | 250 kW | 300 kW |
| AZZURRO 3PH 330KTL-HV-Z0 | 330 kW | 390 kW |
| AZZURRO 3PH 350KTL-HV-Z0 | 350 kW | 420 kW |
All three models share an architecture developed for high-power photovoltaic installations, featuring DC voltage up to 1,500 V, maximum efficiency up to 99% and an IP66 protection rating.
ZCS Azzurro solutions for installers and EPCs
The ZCS Azzurro 3PH 250KTL-HV-Z0, 330KTL-HV-Z0 and 350KTL-HV-Z0 inverters provide a solution for installers, designers and EPCs working on C&I and large-scale photovoltaic projects.
VP Solar supplies the ZCS Azzurro range with technical and commercial support to help identify the most suitable power rating and configuration for each project.
