DC+AC Combiner Box with Type 1+2 SPD on DC Side, 2 Strings 2 MPPT, 16 A Three-Phase and 300 mA RCD
Combined DC+AC combiner box for photovoltaic systems with three-phase inverters, intended for buildings fitted with a lightning protection system on the generator side. It manages 2 PV strings on 2 MPPT inputs.
The DC side is protected by a Type 1+2 surge protective device for 1000 V DC, also able to discharge direct lightning current; the AC side by a Type 2 SPD, a 16 A three-phase miniature circuit breaker and a 300 mA Type A residual current circuit breaker. The 300 mA threshold is typical of protection against electrically caused fires on the supply line, and not of protection against direct contact.
Key features
Type 1+2 SPD on the DC sideA combined arrester suitable for buildings with a lightning protection system, where the discharge of direct lightning current is required.
300 mA Type A RCDHigh threshold residual current protection, aimed at protection against electrically caused fires on the AC line.
16 A three-phase MCBIt protects and isolates the AC line between inverter and distribution board against overloads and short circuits.
2 strings on 2 MPPTThe strings remain separate up to the inverter, with independent maximum power point tracking for each one.
DC and AC protection in a single boxOne wall enclosure instead of two separate boxes, with the internal wiring already carried out.
String voltage up to 1000 VCompatible with string inverters with a maximum input voltage of 1000 V DC.
