    Three-module photovoltaic surge protector for one DC circuit, not three independent circuits. Connected in parallel, with a protective-earth path and separate overcurrent protection. Uc and Up depend on the hardware revision, not the nominal 1000 V designation alone.

    The retained SUP2-PV family table and photographed hardware show different Uc / Up revisions. No single Uc or Up is assigned to this supply record. Select against cold-weather PV open-circuit voltage and equipment impulse withstand using the exact delivered nameplate and applicable manufacturer record. Do not treat the nominal DC designation as the permissible PV voltage.

    01 · Product role

    What this product does in the system.

    Three-module photovoltaic surge protector for one DC circuit, not three independent circuits. Connected in parallel, with a protective-earth path and separate overcurrent protection. Uc and Up depend on the hardware revision, not the nominal 1000 V designation alone.

    Relevant applications

    • PV combiner and inverter DC circuits

    Why ReneWave may shortlist it

    • Three-module photovoltaic surge protector for one DC circuit, not three independent circuits. Connected in parallel, with a protective-earth path and separate overcurrent protection. Uc and Up depend on the hardware revision, not the nominal 1000 V designation alone.

    What changes in practice

    • Connect the complete SPD assembly in parallel between DC +, DC − and the earth bar according to its terminal drawing. Three modules do not mean three PV strings or three switched poles. PE is always connected, never switched.
    • In is the nominal surge-discharge current and Imax the maximum surge-discharge current, both for an 8/20 µs pulse. They are not a 40 kA breaker rating. Coordinate backup protection, earth bonding and equipment impulse withstand; a rated backup fuse size is not established here.
    • Surge diversion only. No overload, short-circuit or residual-current protection; no protection guarantee against a direct lightning strike. Keep the circuit’s isolation and overcurrent devices separate.

    03 · Selection points

    Four practical selection points.

    Match the circuit, surge ratings, earth connection and backup protection.

    1. 01

      Circuit and conductor arrangement

      Connect the complete SPD assembly in parallel between DC +, DC − and the earth bar according to its terminal drawing. Three modules do not mean three PV strings or three switched poles. PE is always connected, never switched.

    2. 02

      Voltage and surge ratings

      The retained SUP2-PV family table and photographed hardware show different Uc / Up revisions. No single Uc or Up is assigned to this supply record. Select against cold-weather PV open-circuit voltage and equipment impulse withstand using the exact delivered nameplate and applicable manufacturer record. Do not treat the nominal DC designation as the permissible PV voltage.

    3. 03

      Separate backup protection

      In is the nominal surge-discharge current and Imax the maximum surge-discharge current, both for an 8/20 µs pulse. They are not a 40 kA breaker rating. Coordinate backup protection, earth bonding and equipment impulse withstand; a rated backup fuse size is not established here.

    4. 04

      Mounting and earth connection

      35 mm DIN rail mounting inside a suitable enclosure. Keep the parallel conductors and PE connection short. Follow the supplied revision’s terminal drawing; isolate before replacing a module. A red status window calls for inspection and replacement, not automatic resetting.
