TE Connectivity


SOLARLOK Residential Combiner Box Now UL Listed

The five-string combiner box offers 30-second, error-proof terminations through factory pre-wired TE SOLARLOK connectors, which have polarity keyed housings to help prevent mismating. Additionally, its light-weight, low-profile design, which includes four pre-drilled knock-out selections, offers installation flexibility in residential solar applications.

The high-performance UL F1 UV-rated material protects the product from harsh impacts and environmental wear and tear -- extending its overall life in outdoor environments.

The SOLARLOK combiner box assembly is used to combine up to five strings in a preterminated connectorized weather-resistant enclosure to meet National Electric Code (NEC) requirements for series fusing of photovoltaic (PV) modules (solar panels).

The combiner box assembly consists of a box, cover (with hinges), transparent dead front lid (under the cover), and 10 pre-terminated SOLARLOK connectors each with a removable dust cover. The box features 4 knockouts (for output wiring), lock tab, mounting slots and pre-wired grounding clip

The interior of the box has 5 fuse holders, pre-wired to the positive SOLARLOK connectors, 5 terminal blocks pre-wired to the negative SOLARLOK connectors, and an equipment terminal block used to ground the equipment. Fuses are not included.
