Question: What are TE Connectivity (TE)´s SOLARLOK DC connector protection caps used for?
Answer: They are plugs that protect PV connectors during installation, helping prevent dust, moisture, and accidental contact before the system is energized.
Question: Why should I use SOLARLOK DC connector protection caps instead of leaving connectors exposed?
Answer: When unconnected or exposed to the environment, PV connectors and terminals can degrade, compromising their integrity. Without protective caps, these become entry points for dust, moisture, and UV degradation. This compromises internal seals and conductivity, creating hotspots or arcing points later.
TE´s SOLARLOK DC connector protection caps help extend connector life, reduce installer risk, and support faster, safer commissioning compared to unprotected connectors.
Question: Are SOLARLOK DC connector protection caps compatible with other brands?
Answer: Yes, they are designed to mate with the Standard Solar Interface (SSI) -standard PV connectors, including many used by major solar panel manufacturers.
Question: How do I remove the DC Connectors protection caps?
Answer: For TE´s connectors, you can use TE’s standard release tools, like a cable coupler. For non-TE connectors, follow the tool guidance of that
manufacturer.
Question: Do they impact the long-term performance of the PV system?
Answer: No, SOLARLOK DC connector protection caps have no impact on the long-term performance of the PV system. Their primary purpose is to help reduce installation-phase failures.
Question: Are they weather-resistant?
Answer: Yes, they provide full sealing (IP68) and UV resistance, so connectors remain protected even if exposed for days or weeks on site.
Question: Who benefits most from using TE´s SOLARLOK DC connector protection caps?
Answer: Solar installers, EPCs, and O&M teams looking to minimize rework, warranty claims, and safety risks during installation.
Question: How do SOLARLOK DC connector protection caps compare to alternatives?
Answer: SOLARLOK DC connector protection caps lock in place, protect O-rings, and allow labeling for better circuit management.
