The ACOPOWER 20A PV In-Line Diode Connector (4-Pair) is the clean, code-compliant solution for preventing reverse current flow in solar panel arrays — TUV-approved, tin-coated copper contacts, and rubber-sealed for weatherproof installations, priced at $58.00.
Built-In Blocking Diode — Prevents current from flowing back from the battery to the solar panel at night or during shading — protects your panels and charge controller without adding a separate diode module.
20A Rated Current — Handles the output of standard 100W–400W solar panels with headroom to spare — no derating needed for typical residential or RV panel strings.
TUV-Approved Connector Head — Independently certified to international safety standards — meets the compliance bar for grid-tied and off-grid installs where certification matters.
Tin-Coated Copper Contacts — Copper core ensures low resistance and high conductivity; tin coating resists oxidation and makes soldering clean and reliable in field conditions.
Rubber Bushing Air-Tight Seal — Each end nut includes a rubber bushing that compresses around the cable for a weatherproof seal — keeps moisture out of the connector junction in outdoor and rooftop installs.
4-Pair Kit — Includes four matched connector pairs, enough to protect a 4-panel array in a single purchase — no hunting for individual connectors.
Drop-In Compatibility — Designed for use between solar panels and switch boxes or charge controllers — installs inline with no rewiring or special tools required.
