DC+AC Combiner Box 1000 V with Type 2 SPD, 2 Strings 2 MPPT, 32 A Three-Phase
DC+AC combiner box for photovoltaic systems with a medium-sized three-phase inverter. It manages 2 photovoltaic strings on 2 MPPT inputs and integrates the surge protection of the direct current side and the circuit breaker protection of the alternating current side in a single wall-mounted enclosure.
On the DC side there is a Type 2 surge protective device for 1000 V DC that protects the inverter inputs against induced overvoltages; on the AC side a Type 2 surge arrester and a 32 A three-phase miniature circuit breaker protect and isolate the grid connection line, with a rating suited to three-phase inverters up to about 20 kW.
Key features
32 A three-phase MCBRating suited to medium-sized three-phase inverters; it protects the AC line against overload and short circuit and allows it to be isolated.
2 strings on 2 MPPTsThe two strings stay independent up to the inverter, useful when the modules are on roof pitches with different orientations.
Double surge protectionType 2 SPDs both on the direct current side at 1000 V and on the alternating current side, upstream and downstream of the inverter.
Simplified installationA single box instead of two separate DC and AC enclosures: fewer cable runs and faster wiring.
Supplied assembledPre-wired box: on site only the photovoltaic strings and the alternating current line remain to be connected.
Wall mountingEnclosure of 319 × 384 × 144 mm and 3.6 kg, to be fixed close to the inverter.
