Connection Technology – Connectors & Adapters for Solar Systems

At Offgridtec, you’ll find solar connectors, splitter sockets, and adapters for virtually any application: from the classic MC4 connection for your solar modules to Anderson-compatible connectors for battery cables, all the way to 12V and USB outlets for your devices. This allows you to connect your system safely and in compliance with standards—without any special tools.

Solar Connectors & Splitter Sockets – Connect Modules Safely

To connect your solar modules, we offer MC4-compatible connectors from Stäubli as well as Offgridtec splitter sockets in 2-, 3-, and 4-way Y- and T-connectors, including extension cables. This allows you to wire multiple modules in parallel without any additional soldering.

SJ50 & Anderson Connectors – For Batteries and Mobile Applications

Offgridtec SJ50 connectors are compatible with Anderson SB50 and are ideal for quickly and safely connecting and disconnecting batteries, solar kits, or portable power consumers—perfect for RVs, boats, or outdoor use.

USB and 12V Outlets – Power on the Go

With our 12V and 24V outlets, as well as USB-A and USB-C dual and triple outlets, you can equip your vehicle, boat, or RV with additional ports for your cell phone, GPS, or cooler. We also offer toggle switches, as well as cigarette lighter and Engel sockets, as compatible connection points.

Tools & Accessories for Installation

The MC4 key wrench ensures that you install strain reliefs and cable glands with the correct torque and without causing damage. For microinverters in the Hoymiles HMS series, we offer matching plug-and-play connection cables in various lengths, and with the Weidmüller PV-Stick field connector set, you’ll be fully equipped for professional use.

Frequently Asked Questions About Connection Technology

• What is a solar connector?

  A solar connector, commonly known as an MC4 connector, securely and weatherproofly connects the cables from your solar panels without requiring soldering.

• Why do I need a branch connector?

  A branch connector allows you to connect multiple solar modules in parallel, for example, using a 2-, 3-, or 4-way Y- or T-connector.

• What is an SJ50 connector?

  The SJ50 is a rugged circular connector, compatible with Anderson SB50, that allows you to quickly connect and disconnect batteries or portable power sources.

• Can I install MC4 connectors without special tools?

  For a safe, standard-compliant installation, we still recommend using the appropriate tools, such as the MC4 wrench, to ensure that the strain relief and cable gland are tightened to the correct torque.

• What is the difference between a 12V outlet and a USB outlet?

  A 12V outlet supplies power to standard automotive connectors, while USB outlets directly charge smartphones, tablets, or other USB devices—in some cases with significantly higher charging power via USB-C.

• Are Offgridtec connectors compatible with other solar systems?

  Yes, our MC4-compatible connectors and branch sockets can be combined with most common solar module connector systems.

• What is the difference between “Connection Technology” and “Wiring & Connecting”?

  Under “Connection Technology,” you’ll find the plugs, sockets, and adapters themselves, while under “Wiring & Connecting,” you’ll find the corresponding cables.
