Solar Charge Controller Communication Cables

Connect, Monitor and Configure Your Solar Charge Controller

A solar charge controller reports and adjusts very little on its own. Communication cables and interfaces link it to a phone, laptop, GX device or network. This range covers Victron VE.Direct cables and interfaces, Morningstar MeterBus converters and the Genasun GV-5-MOD ribbon cable interface adapter. Each lets you read live charging data, change settings and add your controller to a wider monitoring system in caravans, RVs, boats, 4WDs, off-grid homes and commercial sites.

VE.Direct Cables and Interfaces for Victron Controllers

Victron's VE.Direct port carries data between SmartSolar and BlueSolar MPPT controllers and devices such as a Cerbo GX or a pluggable display. VE.Direct cables come in straight and one-side right angle versions from 0.3m to 10m. The right angle connector helps where space is tight inside cabinets, battery boxes and switchboards. Other Victron interfaces in the range include:

• VE.Direct Bluetooth Smart Dongle: adds Bluetooth to VE.Direct products that don't have it built in, so you can use the VictronConnect app on your phone or tablet.
• VE.Direct to USB and USB-C Interface Cables (1.8m): connect a controller to a computer or to a GX device's USB port.
• VE.Direct to RS232 Interface Cable and RS232 to USB Converter: link Victron equipment to serial ports and third-party systems.
• VE.Direct TX Digital Output Cable: unlocks digital output functions on supported controllers.
• VE.Direct Non-Inverting Remote On-Off Cable: provides remote on/off control through the VE.Direct port.

Morningstar and Genasun Communication Adapters

The Morningstar Ethernet MeterBus Converter connects compatible Morningstar controllers to an Ethernet network for remote monitoring. The Morningstar EIA485/RS232 converter provides serial links for data logging and system integration. For Genasun users, the GV-5-MOD Ribbon Cable Interface Adapter provides the interface connection for the GV-5-MOD controller.

How to Choose the Right Communication Cable

Start with the communication port on your controller, then match it to where the data needs to go:

Phone app monitoring: Victron controllers without built-in Bluetooth can use the VE.Direct Bluetooth Smart Dongle.

GX device or remote display: Choose a VE.Direct cable long enough to reach your monitoring point without excess slack. The right angle option suits shallow enclosures. If you're deciding on a central monitoring hub, our Victron GX device comparison explains the differences between the Cerbo, Ekrano, Color Control and Venus.

Computer or third-party systems: Choose the VE.Direct to USB or USB-C cable for modern laptops and GX USB ports. Choose the RS232 options for serial equipment. Morningstar users can pick Ethernet or EIA485/RS232 based on their network.
