YVD.V0A78.1 – Display / HMI Board for ABB ULTRA Inverters

The YVD.V0A78.1 (related to the YVD.V0A78.0 series) is the operator display and HMI (Human-Machine Interface) board designed for the ABB ULTRA series central inverters, including the ULTRA-750, ULTRA-1100, and ULTRA-1500 models.

This board powers the touchscreen or local control panel, enabling operators to monitor real-time performance, view fault diagnostics, adjust settings, and access system data directly on the inverter. It serves as the primary user interface for the liquid-cooled, modular ABB/Fimer ULTRA platform.

In utility-scale solar plants, the display board is exposed to continuous outdoor operation, temperature fluctuations, and electrical stress. Common issues include screen failures, loss of touch functionality, communication errors with the main controller, or complete blank displays – all of which can hinder monitoring and increase response time to faults.

Key Benefits of the YVD.V0A78.1

• Provides clear local monitoring and control of inverter status, energy production, and alarms
• Fully integrated with the ABB ULTRA’s advanced control system and Modbus communication
• Supports quick diagnostics to minimise troubleshooting time in large PV installations
• Designed for the robust, outdoor-rated enclosure of the ULTRA series

At NDC Solar, we specialise in the refurbishment and repair of ABB ULTRA central inverters, including expert handling of the YVD.V0A78.1 display board.

Our Refurbishment & Replacement Services

We offer:

• Comprehensive testing and diagnostics of the YVD.V0A78.1 display/HMI board
• High-quality refurbishment or replacement with reliable equivalent components
