Disassemble a 40-foot folding photovoltaic container that hides a precision design rivalling that of a spacecraft. From power management to mechanical structure, every component speaks to the engineer's creativity.

Mechanical structure: Folding art’s engineering philosophy

 

Three-dimensional expansion system

 

Horizontal slip: the photovoltaic panel is bidirectional through the ball screw, the stroke is 8.4 meters, and the accuracy is controlled at ±1mm

 

Vertical lifting: The support is lifted by the scissor hydraulic rod with a speed of 0.5m/s, and the maximum lifting height is 4.2 meters

 

Angle adjustment: The dual-axis tracking system makes the PV panel pitch adjustable (0-60°), azimuth rotation (±180°)

 

 

Mechanical verification:

 

By ANSYS simulation, the support can withstand 50m/s wind speed (equivalent to category 15 typhoon)

 

Hinge wear < 0.01mm after 2 million folding tests

 

 

Space magic

Integrated in standard containers by three-dimensional stacked structure:

 

Photovoltaic array (540㎡ development area)

 

1.2MWh energy storage system

 

Smart power distribution cabinet (with 6 AC/DC outputs)

 

Water cooling system (flow 30L/min)

 

 

Power electronics: The final efficiency of energy conversion

Optical storage machine

Three-level topology with silicon carbide (SiC) devices:

 

99% conversion efficiency (97% for traditional IGBT solutions)

 

Power density is 3W/cm³ and volume is 60% less

 

150% overload supported for 10 minutes

 

Dynamic MPPT algorithm

Deep learning-based photovoltaic maximum power point tracking:

 

Tracking speed is accelerated to 20ms/time under cloud occlusion conditions

 

18% increase in power generation under shadow conditions

 

 

Battery management system

 

Four-level architecture guard security:

 

Core level: Independent voltage/temperature monitoring per cell

 

Module level: fire aerogel + burst valve double protection

 

System level: insulation monitoring + active balance control

 

Cloud-level: AI health prediction, accuracy ±2%

 

the material revolution: from the laboratory to the industrialization leap

 

Photovoltaic panel innovation

 

Lightweight: 2mm ultra-thin glass + carbon fiber backplane, 40% lighter

 

Self-cleaning: Titanium dioxide nano coating, rain washing can remove 95% dust

 

Anti-pid: Special packaging process makes potential-induced attenuation < 1%/ year

 

Structural material

 

Box: 7 series aluminum alloy frame + aramid honeycomb sandwich panel, 55% lighter than steel structure

 

Bearings: silicon nitride ceramic bearings, lubrication-free life up to 20 years

 

Limit test:

 

Salt spray test: 480 hours without corrosion (ISO 9227 standard)

 

Vibration test: 5-500Hz random vibration, cumulative 200 hours without structural damage
