{"product_id":"pv-surge-protection-550v-class-ii","title":"PV Surge Protection Device Class II 550VDC 2-Pole | GAVE Electro","description":"\u003cp\u003eThis 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.\u003c\/p\u003e\u003ch2\u003eKey features of this PV surge protection device\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eProtection class\u003c\/strong\u003e, Class II \/ Type 2 SPD for DC PV applications\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum voltage\u003c\/strong\u003e, 550VDC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoles\u003c\/strong\u003e, 2-pole, covering positive and negative PV conductors\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProtection element\u003c\/strong\u003e, high energy varistor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting\u003c\/strong\u003e, DIN rail\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cp\u003eFit this into DC combiner boxes on off-grid and hybrid solar systems where string voltage stays at or below 550VDC.
