PV Surge Protection Device Class II 550VDC 2-Pole | GAVE Electro

This GAVE Electro DC surge protection device gives 2-pole overvoltage protection for solar PV strings rated up to 550VDC. It fits in parallel with the DC string cables, sitting between panels and inverter to intercept lightning strikes and induced surges before they reach sensitive equipment. The unit mounts to a DIN rail, making it a straightforward addition to an existing combiner box or distribution panel.

Key features of this PV surge protection device

• Protection class, Class II / Type 2 SPD for DC PV applications
• Maximum voltage, 550VDC
• Poles, 2-pole, covering positive and negative PV conductors
• Protection element, high energy varistor
• Mounting, DIN rail

Applications

Fit this into DC combiner boxes on off-grid and hybrid solar systems where string voltage stays at or below 550VDC. It is aimed at low to medium voltage arrays rather than high-voltage commercial strings.

Installation notes

Wire it in parallel with the DC string conductors. Installation should be carried out by a qualified electrician, and it must not be used where string voltage exceeds 550VDC.
