ETERNAL WATT · SOLAR INDUSTRIAL FAN

Solar HVLS Ceiling Fans

for Factories, Warehouses & Large Industrial Spaces

Right under the roof, right next to the panels. Eternal HVLS fans integrate solar drive out of the box — solar-first, grid-backed, and still running on sunshine even during a power outage.

SOLUTION · SOLAR INDUSTRIAL FAN SYSTEM

Put rooftop solar directly to work on indoor air circulation

Rooftop solar, energy management, HVLS fans, and remote control come together in one clear energy path—maintaining comfortable airflow while increasing on-site solar utilization.

SOLAR PRIORITY · STEADY AIRFLOW

01

Maximize solar use while holding the set fan speed

On-site solar powers the HVLS fans first. When solar output is insufficient, the grid fills the load gap at the controller, maintaining uniform, comfortable air circulation across tall indoor spaces.

Green solar and amber grid lines feed Eternal TS6000 while the HVLS fan continues operating

DAYLIGHT OUTAGE RESILIENCE

02

When the grid fails, sunshine keeps essential airflow moving

During a daytime grid outage, the system adjusts fan operation to available solar power so occupied work zones retain essential air movement.

REMOTE MULTI-ZONE CONTROL

03

Coordinate facility-wide fans remotely with a clear energy view

With an optional external 4G or Wi-Fi module, operators can monitor fan status across zones, start or stop zones together, and see the solar and grid contribution.

An operator uses a tablet and external communication module to monitor and control multiple HVLS fans by zone

OPERATING MODES · FACTORY AIRFLOW

One system for three facility operating states

Maintain effective air circulation in enclosed or semi-enclosed tall spaces, then adapt energy sources and controls to power availability and zone demand.

Daily operation

Solar first, grid support

Hold the set fan speed while maximizing on-site use of rooftop solar.

  • Grid power fills gaps as solar output changes
  • Designed for long operating hours
  • Calculate savings from solar conditions and runtime
Daytime outage

Maintain essential airflow whenever sunlight is available

After a grid outage, fan speed follows available solar power to preserve basic airflow in occupied work zones.

  • Actual speed varies with sunlight and solar capacity
  • Low light does not equal rated airflow
  • Continued operation is not promised without sunlight
Multi-zone management

Run only where needed to reduce wasted airflow

Use the communication module to monitor fan status and coordinate zones by shift, workstation, or space usage.

  • Optional 4G or Wi-Fi configurations
  • Control scope depends on platform protocol
  • Prioritize zones where people are actually working
