DC Combiner Boxes

ETEK Solar DC PV Combiner Boxes aggregate multiple solar strings into a protected DC output for string or central inverters. Typical configurations range from 1 to 24+ input strings, with isolated positive and negative busbars, touch-safe fuse holders, and optional string monitoring.

Each input is protected by gPV DC fuses, while the output circuit includes a DC isolator switch and Type 1+2 DC surge protective device. The enclosure is IP65 / IP66 rated, UV-stabilized, and fitted with cable glands and anti-condensation vents. ETEK Solar DC PV combiner boxes are a proven solution for rooftop solar arrays, ground-mounted PV plants, and off-grid hybrid systems.
