DC+AC Combiner Box 1000V with Type 2 SPD, 2 Strings 2 MPPT, 16A Three-Phase
DC+AC combiner box for photovoltaic systems with a three-phase inverter. It manages 2 independent photovoltaic strings on 2 MPPT inputs and integrates in the same enclosure the surge protection of the direct current side and the circuit breaker protection of the alternating current side.
On the DC side a Type 2 surge protective device for 1000V DC is installed, which limits overvoltages induced by indirect lightning strikes and by grid switching operations, protecting the MPPT inputs of the inverter. On the AC side there are a Type 2 surge arrester and a 16A three-phase miniature circuit breaker that protects and isolates the connection line between the inverter and the distribution board. It is wall-mounted close to the inverter, on systems without a lightning protection system.
