DC Combiner Box 1000 V with Type 1+2 SPD for 3 Photovoltaic Strings and 3 MPPT
DC-side combiner box for photovoltaic systems up to 1000 V DC, configured for 3 photovoltaic strings on 3 independent MPPT inputs. It is the typical solution for medium-to-large residential systems or for small commercial systems with roof pitches of different exposure, where each string has to be tracked separately by the inverter.
Protection is provided by a Type 1+2 surge protective device: a combined device that discharges to earth both the impulse currents from direct lightning strikes (class I test) and the induced transient surges (class II test). This class is the one prescribed when the building is equipped with a lightning protection system or when the distance between the modules and the inverter is significant. The box is wall-mounted along the route of the string cables, upstream of the DC inputs of the inverter.
Key features
3 strings and 3 MPPTsThree independent string circuits, each dedicated to one maximum power point tracker of the inverter.
Type 1+2 surge arresterCombined protection against direct lightning strikes and transient surges in a single device.
Up to 1000 V DCRated for the open-circuit voltage of standard photovoltaic strings.
For buildings with an LPSArrester class suitable for buildings provided with a lightning protection system.
Enclosure 319 × 259 mmDimensions 319 × 259 × 144 mm and a weight of 4.2 kg, with room for wiring the three strings.
Ready for installationBox assembled and factory-wired, to be connected only to the string cables and to the inverter.
