DC+AC Combiner Box Type 1+2 SPD, 2 Strings 2 MPPT, 32 A Single-Phase, 40 A 300 mA RCCB
Combined DC+AC combiner box for single-phase photovoltaic systems, with complete protection on both sides of the inverter. It collects 2 PV strings on 2 MPPT inputs and is the recommended solution for homes fitted with a lightning protection system.
The DC side is protected by a Type 1+2 surge protective device for 1000 V DC and the AC side by a second Type 1+2 arrester: both are also able to discharge direct lightning current. The AC line is completed by a 32 A single-phase miniature circuit breaker and by a 40 A residual current circuit breaker with a 300 mA threshold, sized for protection against electrically caused fires.
Key features
Type 1+2 SPD on both sidesCombined arresters on DC and on AC, suitable for buildings with a lightning protection system.
40 A 300 mA residual current protectionThe 40 A residual current circuit breaker with a 300 mA threshold protects the AC line against earth faults and electrically caused fires.
32 A single-phase MCBIt protects the AC line against overload and short circuit and allows the inverter to be isolated from the distribution board.
2 strings, 2 MPPTThe two strings remain independent up to the inverter, with separate maximum power point tracking for each one.
All the protective devices in a single boxSPDs, MCB and RCCB already wired in one wall enclosure, instead of several separate boxes.
String voltage up to 1000 VSuitable for single-phase string inverters with a maximum input voltage of 1000 V DC.
