It incorporates a 12 A gPV fuse per pole to protect against reverse currents, a general 40 A 1000 VDC isolator that allows safe operation and maintenance, and a Type II PV surge arrester that protects the inverter and generator against transients. Its polycarbonate enclosure with double insulation (Class II), IP65 and IK7 protection rating, is designed for outdoor use (depending on installation) and to withstand the demands of rooftops and residential or small commercial environments. The internal DIN rail layout, accessible terminals, and clear labeling reduce installation time and facilitate future inspections.\u003c\/p\u003e\n\n\u003ch3\u003eMain Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1E\/1S topology: 1 MPPT with 1 string (differentiated input and output in +\/–).\u003c\/li\u003e\n  \u003cli\u003egPV fuses 10×38 mm of 12 A per pole for selectivity and protection against reverse currents.\u003c\/li\u003e\n  \u003cli\u003eMultipole DC isolator 40 A – 1000 VDC to isolate the circuit during maintenance operations.\u003c\/li\u003e\n  \u003cli\u003eType II PV surge protection (PST31PV cartridge): In 20 kA, Imax 40 kA, Up ≈ 3.6 kV, Uc ≈ 1060 VDC.\u003c\/li\u003e\n  \u003cli\u003ePolycarbonate enclosure IP65 · IK7 · Class II (double insulation), suitable for protected outdoor use.\u003c\/li\u003e\n  \u003cli\u003eCompact design (≈ 231 × 238 × 118 mm) with streamlined wiring and integrated earth terminal.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eAdvantages or Benefits\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eQuick and tidy installation: marked polarities, front access to fuses and isolator, reduced risk of error.\u003c\/li\u003e\n  \u003cli\u003eGreater DC side safety: load disconnection, selective gPV protection, and PV SPD coordinated with the inverter.\u003c\/li\u003e\n  \u003cli\u003eReduced downtime: transients are mitigated and the inverter is protected against overvoltages.\u003c\/li\u003e\n  \u003cli\u003eSimple maintenance: quick replacement of gPV cartridges and visual verification of SPD status.\u003c\/li\u003e\n  \u003cli\u003eOutdoor robustness: IP65 and IK7 ensure watertightness and mechanical resistance on rooftops and pergolas.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003ePurpose or Applications\u003c\/h3\u003e\n\u003cp\u003eIndicated for residential self-consumption and light commercial use when using an inverter with \u003cstrong\u003e1 MPPT\u003c\/strong\u003e and a single string.
