DC+AC Combiner Box 1000 V with Type 2 SPD, 4 Strings 2 MPPT, 50 A Three-Phase
DC+AC combiner box for medium and large three-phase photovoltaic systems. It manages 4 PV strings on 2 MPPT inputs (two strings in parallel for each MPPT) and protects both the DC section and the AC line inside a single wall-mounted enclosure.
Protection is provided by a Type 2 surge protective device for 1000 V DC on the string side, a Type 2 SPD on the grid side and a 50 A three-phase miniature circuit breaker, the highest rating in the series, suitable for three-phase inverters up to around 30 kW. This is the typical configuration for systems on warehouses, farms and small production facilities.
Key features
Up to 4 PV stringsIt collects four strings and distributes them across two MPPT inputs of the inverter, two strings for each tracker.
50 A three-phase MCBThe highest rating in the range: it protects and isolates the AC line of medium and high power three-phase inverters.
Type 2 SPD on DC and ACProtection against induced and switching surges upstream and downstream of the inverter, on both sides of the system.
Suitable for commercial systemsA configuration designed for installations on warehouses, farms and small production facilities.
A single DC+AC boxIt replaces two separate boxes, reducing the number of wall enclosures and the cable runs.
Supplied assembled and wiredReady for connection of the strings and of the AC line, with no component assembly on site.
