The ZCS Azzurro 3PH 250KTL-HV-Z0 \/ 330KTL-HV-Z0 \/ 350KTL-HV-Z0<\/strong> range is designed for energy conversion in medium- and large-scale commercial and industrial photovoltaic systems<\/strong>, where efficiency, reliability and flexibility in PV array configuration are key requirements.<\/p>\n

The range is available in three rated AC power sizes: 250 kW, 330 kW and 350 kW<\/strong>, with typical DC power ratings of 300 kW, 390 kW and 420 kW<\/strong> respectively.<\/p>\n

High DC-side flexibility<\/h3>\n

The inverters support a maximum input voltage of 1,500 V<\/strong> and operate over a wide MPPT voltage range from 500 to 1,500 V<\/strong>, with a full-load operating range from 860 to 1,300 V.<\/p>\n

The configuration features 6 independent MPPTs on the 250 kW model and up to 8 MPPTs on the 330 and 350 kW versions<\/strong>, providing greater flexibility when designing PV arrays with multiple strings. The maximum input current per MPPT is 60 A<\/strong>.<\/p>\n

Efficiency and reliability for high-power PV systems<\/h3>\n

The range achieves a maximum efficiency of up to 99%<\/strong>, helping maximise the conversion of energy generated by the photovoltaic array.<\/p>\n

The IP66 protection rating<\/strong> makes the inverters suitable for outdoor installations and demanding environmental conditions. A forced-air cooling system with controlled fan speed<\/strong> supports reliable operation at the high power levels for which these inverters are designed.<\/p>\n

Protection, diagnostics and monitoring<\/h3>\n

The ZCS Azzurro 3PH 250-350KTL-HV-Z0 inverters integrate AC- and DC-side surge protection devices<\/strong> and support firmware updates and diagnostic operations via USB.<\/p>\n

The range can also be monitored through the ZCS Azzurro app and portal<\/strong>, allowing users to view energy production, consumption and the main operating parameters of the photovoltaic system.<\/p>\n

Three power ratings for C&I photovoltaic projects<\/h3>\n

The range includes:<\/p>\n\n\n\n\n\n\n\n
Model<\/strong><\/td>\nRated AC power<\/strong><\/td>\nTypical DC power<\/strong><\/td>\n<\/tr>\n<\/thead>\n

AZZURRO 3PH 350KTL-HV-Z0<\/strong><\/td>\n350 kW<\/td>\n420 kW<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

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<\/strong>.<\/p>\n

ZCS Azzurro solutions for installers and EPCs<\/h3>\n

The ZCS Azzurro 3PH 250KTL-HV-Z0, 330KTL-HV-Z0 and 350KTL-HV-Z0<\/strong> inverters provide a solution for installers, designers and EPCs working on C&I and large-scale photovoltaic projects<\/strong>.<\/p>\n

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<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":"
