DC+AC Combiner Box 1000 V with Type 2 SPD, 2 Strings 2 MPPT, 20 A Three-Phase
Combined DC+AC combiner box for photovoltaic systems with residential size three-phase inverters. It manages 2 PV strings on 2 MPPT inputs and integrates in a single wall-mounted enclosure the surge protection of the DC side and the protection of the AC line.
On the DC side there is a Type 2 surge protective device for 1000 V DC, which limits the surges induced by indirect lightning strikes and by grid switching, protecting the inverter inputs. On the AC side there are a Type 2 SPD and a 20 A three-phase miniature circuit breaker, which protects and isolates the connection line between inverter and distribution board. This is the standard configuration for three-phase systems without a lightning protection system.
Key features
Standard configuration for three-phase systemsTwo strings, two MPPT and a 20 A MCB: the most common combination on three-phase residential photovoltaic systems.
Type 2 SPD on DC and on ACProtection against induced and switching surges upstream and downstream of the inverter, on the two sides of the system.
2 strings on 2 independent MPPTEach string keeps its own maximum power point tracker, useful with roof pitches of different orientation or tilt.
20 A three-phase MCBIt protects the AC line against overload and short circuit and allows it to be isolated during maintenance.
A single box for DC and ACIt reduces the number of wall enclosures, the cable runs and the installation time compared with two separate boxes.
Supplied assembled and wiredOnly the string and line connections remain to be made on site.
