Dyness LV Link-A Communication Box

The Dyness LV Link-A Communication Box is a purpose-built battery communication hub designed to simplify the expansion of compatible Dyness low-voltage lithium battery systems. In solar and backup installations where clean communication between multiple battery modules matters, the LV Link-A gives installers a structured and scalable way to connect supported battery units while keeping the system neat, stable, and easier to manage.

For growing energy storage systems, this unit plays an important role in communication and coordination. The LV Link-A supports CAN and RS485 communication, allowing the battery system to communicate efficiently with compatible equipment while helping maintain stable operation across expanded battery configurations. It supports up to 4 access systems, making it a practical choice for installers planning structured battery expansion in residential and light commercial solar applications.

Its compact size makes it especially useful where installation space is limited. With dimensions of 135 × 112 × 36 mm and a net weight of 0.46 kg, the Dyness LV Link-A is easy to position in battery rooms, utility spaces, garages, and other indoor solar installation areas without adding clutter. The wall-mounted design also helps maintain a cleaner and more professional finish on site.

The unit is designed for indoor use and built to handle demanding operating conditions. It works within an operating voltage range of 42 to 60V, supports an operating temperature range of -20°C to 55°C, carries an IP20 protection rating, and is certified to CE-EMC standards. For installers and resellers looking for a reliable Dyness battery expansion communication solution, the LV Link-A is a compact but important component in building a scalable and well-organised low-voltage energy storage system.
