Single-phase AC protection panel for photovoltaic systems from 1 to 3 kW, 16 A 230 V. Integrates a 300 mA Class A residual current circuit breaker with overcurrent protection, in/out configuration and Class II SPD surge arrester 2P 230 V 15 kA.12-module IP65 box, supplied with single-line diagram and declaration of conformity. It does not include interface protection: it is designed for systems below the 11,08 kW threshold.

Single-phase AC protection panel for 3 to 5 kW photovoltaic systems, 25 A 230 V. Integrates a 300 mA Class A RCBO and Class II SPD surge arrester 2P 230 V 15 kA.12-module IP65 box with single-line diagram and declaration of conformity. It is a protection and disconnection panel: the interface protection remains the one integrated in the inverter.

Single-phase AC protection panel for 5 to 6 kW photovoltaic systems, 32 A 230 V: the maximum size allowed on a single-phase connection. It integrates a Class A 32 A 300 mA residual current circuit breaker with overcurrent protection, switch in in/out configuration, and Class II 2P 230 V 15 kA SPD surge protector.Compact IP65 8-module box with single-line diagram and declaration of conformity.

Three-phase interface panel from 12 to 15 kW, 25 A 400 V, compliant with CEI 0-21 for one inverter. Integrates the Interface Protection System (SPI), the contactor interface device, the Class A residual-current circuit breaker with overcurrent protection, and the surge arrester.36-module IP65 box, supplied with single-line diagram, declaration of conformity, and SPI test report: the three documents required by the distributor for connection.

Three-phase QAC 16/20 kW interface cabinet for PV systems from 16 to 20 kW, 32 A at 400 V, compliant with the Italian standard CEI 0-21.Pre-wired and factory tested: it houses the main breaker, interface device, interface protection system and surge arrester in a 36-module IP65 class II enclosure. Supplied with wiring diagram, declaration of conformity and SPI test report.

Three-phase QAC 36/44 kW interface cabinet for PV systems from 36 to 44 kW, compliant with the Italian standard CEI 0-21.54-module enclosure, 480x540x220 mm, IP66 class II: it integrates main device, interface device, interface protection and surge arrester in a single pre-wired, factory-tested unit. Supplied with wiring diagram, declaration of conformity and SPI test report.

Three-phase AC panel 6/8 kW for protecting the AC line downstream of the photovoltaic inverter: IMTD 4x16 A class A 300 mA and class II SPD surge arrester 4P 400 V - 15 kA in an IP65 18-module box, with single-line diagram and declaration of conformity Di.co. Does not contain SPI or DDI contactor: on systems up to 11,08 kW, the interface protection integrated in the inverter is sufficient according to CEI 0-21.

CEI 0-21 interface panel for photovoltaic systems from 75 to 95 kW on one inverter, rated current 160 A at 400 V. Includes SPI, 140 A-AC3 DDI contactor, IMTD 4x160 A-10 kA with DDR backup, inverter protection IMT, SPD surge arrester and fuse holders dedicated to SPI power supply and measurements, in IP66 enclosure with 140 modules. Supplied with single-line diagram, Di.co and SPI test report.

Three-phase AC panel 8/11 kW with IMTD 4x20 A class A 300 mA, IMT input/output switch-disconnector and class II SPD surge arrester 4P 400 V - 15 kA in an IP65 18-module box, with single-line diagram and Di.co. It is the last size in the series that remains below the 11,08 kW threshold of the simplified CEI 0-21 procedure: it does not include an SPI or DDI contactor, because at this power level the inverter interface protection is sufficient.
