Exact reference · SUP2-PV-2P-500V
Two-module photovoltaic surge protector, connected in parallel with the DC circuit. Diverts transient surges to protective earth; separate overcurrent protection is required. Uc and Up depend on the hardware revision, not the nominal 500 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.
Two-module photovoltaic surge protector, connected in parallel with the DC circuit. Diverts transient surges to protective earth; separate overcurrent protection is required. Uc and Up depend on the hardware revision, not the nominal 500 V designation alone.
Relevant applications
- PV combiner and inverter DC circuits
Why ReneWave may shortlist it
- Two-module photovoltaic surge protector, connected in parallel with the DC circuit. Diverts transient surges to protective earth; separate overcurrent protection is required. Uc and Up depend on the hardware revision, not the nominal 500 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.
System position
Parallel surge diversion, not series interruption.
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.
The circuit supplies the load; the SPD is connected in parallel, not in series with the load.

Four practical selection points.
Match the circuit, surge ratings, earth connection and backup protection.
- 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.
- 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.
- 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.
- 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.
