Victron Zigbee to RS485 Converter | ASS300420100

The Victron Zigbee to RS485 converter lets Victron GX devices talk wirelessly to RS485-based equipment. It removes the need to run signal cables between a GX device and RS485 gear such as Victron MPPT charge controllers, which matters most in retrofit jobs or larger sites where cable routing is awkward.

Key features

• Protocol conversion, converts Zigbee wireless signals to RS485 serial communication.
• Compatibility, works with the Victron GX product range for solar monitoring and energy management.
• Weight, 157g, small enough for confined enclosures or distribution boards.
• System fit, designed for Victron's ecosystem, including MPPT solar charge controllers and other RS485-capable devices.
• Wiring, replaces RS485 signal cabling with a Zigbee wireless link.

How it works

RS485 is a common serial standard across Victron's solar and energy storage products, but dedicated signal cables are not always practical to install. This converter keeps the RS485 protocol intact at both ends while carrying the data over Zigbee instead of copper. Units are used in pairs, or as part of a wider Zigbee network: one connects at the GX device, the other at the RS485 device, and data passes between them wirelessly. It is part of Victron's GX accessories range and sits within the VRM and Venus OS ecosystem.

Applications

• Wireless RS485 integration where cable routing is impractical on off-grid solar sites.
• Linking RS485-enabled Victron MPPT charge controllers to a GX device without signal cabling.
• Retrofit installations where adding RS485 wiring is not feasible.
• Commercial and industrial solar sites that need a low-cable monitoring setup.

Installation notes

Installation should be carried out by a qualified electrician or an installer familiar with Victron GX systems and RS485 communication. Check compatibility with your GX device and firmware version before fitting, and follow Victron's published guidance for GX accessory Zigbee network setup.
