The ISL, ISA, and ISB series of photovoltaic switchboards are ideal for the management and protection of small- and medium-sized installations.

Inside each switchboard, the protection and control circuits for the photovoltaic field strings and the AC section of the inverter are already wired. To complete the installation, the installer simply needs to position and secure the ISL switchboard and connect the photovoltaic strings and the inverter.
The ISL series switchboards consist of two distinct and separate subsystems: AC board and DC board.

The ISB and ISA series switchboards, instead, include protections for the DC section of the installation.

The switchboard features a compact and elegant design, suitable for both outdoor and indoor installation thanks to IP65 protection rating. Equipped with a UV-resistant transparent door.
Photovoltaic panel connectors allow for quick and secure connections and are supplied with caps to ensure IP65 insulation.
Surge protectors rated at 20 kA, available in 600 Vdc and 1000 Vdc versions for optimal coordination with the system voltage.
Rotary disconnector rated 600 Vdc or 1000 Vdc depending on the system voltage, ideal for safe protection and isolation of the strings. Equipped with a lockable handle.
Differential circuit breakers, single-phase or three-phase, Class A or AC, 300 mA, with breaking capacity of 6 kA or 10 kA.
AC surge protectors rated at 20 kA, available in single-phase or three-phase versions.
