External Turbo Ventilator Intercooler (ETVI)

UTICA® specialises in premium solar technology in Singapore, delivering residential solar PV systems that combine technical precision with architectural sensitivity. From compact homes to large landed properties, every installation is tailored to match roof structure, aesthetics, and energy goals.

Each project begins with a comprehensive site visit to evaluate roof type, structural load, and electrical compatibility. Based on these insights, we design a customised solar solution that enhances both performance and curb appeal. Homeowners also benefit from full-service aftercare, including real-time monitoring, predictive maintenance, and access to Renewable Energy Credits (RECs), effectively turning solar adoption into a long-term, sustainable asset.

To further optimise solar installations, UTICA® integrates the External Turbo Ventilator Intercooler (ETVI), a performance-driven cooling solution designed to regulate inverter heat.

Much like forced ventilation systems in precision engineering, the ETVI reduces inverter temperatures by up to 10 °C. Under Singapore’s intense tropical heat, this reduces thermal throttling, improves electrical conversion efficiency, and significantly extends hardware lifespan,

What is the ETVI?

The ETVI is a ventilation and heat-exchange system that actively cools inverters and associated electronics mounted near or on rooftops. It combines turbo-style forced airflow with an intercooler heat exchanger, dissipating heat more effectively during peak solar generation hours.

This ensures that the inverter, and MPPT optimisers where applicable, continue to operate at cooler, more stable temperatures, increasing reliability and performance throughout the day.

1. Improved Efficiency & Reliability

Solar inverters naturally lose efficiency under high heat. By lowering operating temperatures, the ETVI preserves energy output, reduces thermal degradation, and extends the lifespan of inverters and optimisation modules.

2. Quiet & Discreet Cooling

Designed to integrate with the roofline, the ventilator remains subtle and unobtrusive. Ideal for architecturally sensitive residences, it delivers performance without visual clutter.

3. Smart Ecosystem Integration

As part of UTICA®’s ecosystem, the ETVI works seamlessly with Rapid 600 panel-level MPPT optimisers and the Solargaga app, enabling real-time monitoring, predictive maintenance, and remote diagnostics.

The steps are as follow:

1. Architectural & System Review

Assessment of roof structure, finish, orientation, and load capacity to define solar layout and ETVI placement.

2. System Design

• Select solar modules and inverters with high heat tolerance for Singapore’s tropical climate.
• Define ETVI placement to enhance cooling airflow while maintaining a clean, minimal appearance.
• Apply German-engineered, tropicalized materials and structural designs suited to residential quality standards.

3. Installation

Clamp-mounted or concealed mounting systems are used to protect the integrity and appearance of your roof. ETVI components are installed flush or discreetly integrated to preserve architectural aesthetics.

4. Commissioning & Monitoring

After installation, the system is calibrated for peak performance. Homeowners are provided with access to real-time system monitoring via a mobile app, including remote diagnostics and predictive maintenance alerts.

• Preserves architectural integrity: Minimal visual intrusion keeps the design language intact.
• Optimizes solar ROI: Cooler electronics yield better efficiency and reduce downtime.
• Enhances longevity: Equipment lasts longer with lower operational stress.
• Safe, premium quality: UTICA® is TÜV ISO‑9001 and BizSAFE‑star certified, with 20+ years’ presence in Singapore.

With innovations like the ETVI, UTICA® ensures solar systems in Singapore are smarter, cooler, and longer-lasting. By focusing on engineering precision and reliability, we transform every rooftop into a stable, high-performance energy asset built for decades of confidence.
