Accessories & Expansions for PV Electronics

At Offgridtec, you’ll find accessories for nearly every solar electronics component: connectors and replacement parts for microinverters, interface cables for Victron devices, junction boxes for your electrical installation, and smart sensors for monitoring and automation. This allows you to maintain your system or upgrade it as needed, without having to replace the entire system at great expense.

Connectors & End Caps

For clean, tight connections, we offer Betteri BC01 sockets, plugs, and end caps for Envertech, Hoymiles, and Huawei inverters, as well as MC4 dust caps that reliably protect unused connections from moisture and dirt.

Accessories for Microinverters

For our Hoymiles microinverters, you’ll find compatible field and trunk connectors, end caps, and release tools for the HMT series, as well as DTU Pro data loggers for Wi-Fi data transmission. To optimize the performance of your solar modules, you can also get Tigo TS4 optimizers and the Tigo TAP access point for wireless communication.

Victron Interfaces & Monitoring

For your Victron system, you’ll find RS485-to-USB and VE.Direct cables, the MK3 USB interface for configuring your devices, the VM-3P75CT Energy Meter for three-phase consumption measurement, and the Cerbo GX MK2 communication hub for centralized system monitoring. A galvanic isolator provides additional protection for your system against electrolytic corrosion.

Distribution Boxes & Connection Technology

Our IP66 distribution boxes with DIN rails are available in sizes ranging from 4 to 36 TE—weatherproof, UV-resistant, and ideal for neatly and securely housing fuses, switches, or distribution equipment. You’ll also find matching connection cables for microinverters and Growatt devices.

Smart Sensors & Accessories

With the Ruuvi Tag 4-in-1 Bluetooth sensor, you can monitor temperature, humidity, air pressure, and motion, while the everHome EcoTracker provides real-time visibility into your electricity consumption. For your RV, Votronic tank electrodes and D+ simulators are useful additions to your system.

Frequently Asked Questions About Electronics Accessories

• What accessories do I need for my microinverter?

  Depending on the model, you’ll need compatible connectors, end caps, connection cables, and, if necessary, a data logger like the Hoymiles DTU-Pro to retrieve your system’s yield data via Wi-Fi.

• What is a Field Connector or Trunk Connector from Hoymiles?

  The Field Connector connects the HMS connection cable to the microinverter, while the Trunk Connector combines multiple connection cables into a single AC line.

• What is an energy meter like the Victron VM-3P75CT used for?

  An energy meter measures your actual three-phase electricity consumption and thus provides the data needed for your system to optimally coordinate power generation, storage, and consumption.

• What does the Victron Cerbo GX communication hub do?

  The Cerbo GX centrally networks your Victron devices, clearly displays all system data, and enables remote monitoring of your system via the VRM platform.

• What is the purpose of a galvanic isolator?

  A galvanic isolator breaks the electrical connection between two circuits, thereby preventing electrolytic corrosion—for example, between the shore power connection and the vehicle’s electrical system.

• What is a Tigo TAP?

  The Tigo TAP is a wireless access point that collects data from your Tigo optimizers, enabling you to monitor individual solar modules.

• How many TE do I need for my distribution box?

  That depends on the number of fuses, circuit breakers, and distribution components you have. For smaller systems, 4 to 9 TE are often sufficient; larger installations with multiple circuits frequently require 18 TE or more.
