About Us

Our mission is to optimize and develop technologies for energy conversion from renewable and sustainable sources (e.g., wind, hydro, hydrogen). We are projected into the world of automation, digitalization, and Industry 4.0 evolution.

We support our clients from both an environmental and social perspective. We work towards a more resilient energy production and distribution, aiming to reduce dependency and risks associated with fossil fuels.

Our ambition is to build global partnerships, integrating territories and companies to support future development towards sustainable energy and decarbonization.

Sustainability

Our Expertise

Since 2009, @moStacy S.r.l.'s background has been based on research, analysis, and collaboration with companies in green hydrogen, wind, and other sectors. We have proven experience in producing detailed reports on various energy and automation projects.

We develop new technologies (from single components to full systems) and effective solutions to address issues related to different energy carriers. Special attention is given to short and long-term energy storage – thermal, mechanical, and thermochemical – always evaluating the technical effectiveness of cutting-edge solutions.

System Down in Fault?

We intervene on the full Elpower Cleanverter range (series 10-30, 40-100, 150-250 TL and PV). We understand DSP control logic and repair power electronics.

  • FAULT Diagnostics and IGBT Module Repair
  • On-Site Maintenance & Revamping

Fault Codes & Common Errors Diagnostics

If your inverter display shows one of these FAULTS, contact us immediately. Avoid forced restarts to prevent IGBT damage.

Display Message (FAULT) Error Description Recommended Action
FAULT GRID / MISSING GRID Grid failure or voltage/frequency parameters out of tolerance. Check Protections
FAULT IAC HIGH / OVERCURRENT Instantaneous overcurrent. Possible short circuit or hardware failure. DO NOT RESTART - Call Us
FAULT VDC HIGH DC Bus Overvoltage. Braking chopper anomaly or excess energy. Request Analysis
OVERTEMP / THERMAL FAULT Heatsink or power module overtemperature. Faulty fans or sensors. Fan Maintenance
EMERGENCY STOP Safety chain open. Emergency button pressed or auxiliary contact open. Reset Circuit
