System solution for photovoltaic systems with connection terminals - Fault-resistant Y-connection for use according to VDE 0100-712 (IEC 60364-7-712) - Low DC protection level: below 4.0 kV (Uoc max = 1000 V DC with V20-C/0-500PV) - Low DC protection level: below 3.0 kV (Uoc max = 900 V DC with V25-B+C/0-450PV) - Low DC protection level: below 2.6 kV (Uoc max = 600 V DC with V50-B+C/0-300PV) - Each with 6 parallel connection terminals up to 6 mm² per polarity (+ and -) - Pre-assembled in an IP65 enclosure. Note: 6 PV strings can be connected in parallel on the terminals. The technical specifications (string voltage, ...) as well as the conditions of the inverter (number of MPP trackers) must be observed. Additional measures may be required in case of potential condensation formation.
