Solar panels
During production hours, the panels directly supply the DC refrigeration architecture and reduce energy required from other sources.

PORTABLE SOLAR COLD CHAIN
Walk-in cooler and freezer capacity wherever it is needed.
A mobile, modular container platform for food storage, agriculture, events, emergency response and remote locations—with solar capability and continuous temperature monitoring options.
Request an evaluationFOUR AVAILABLE ENERGY SOURCES
Continuous operation, organized by priority.
The system uses available solar energy first and coordinates the selected backup sources to maintain refrigeration as production and operating conditions change.
Lithium batteries
Stored energy supports nighttime operation, low-solar periods or outages according to the designed autonomy.
Nighttime backupGenerator
It can support operation or charging when battery reserves are insufficient and utility service is unavailable, depending on the project design.
Contingency sourceUtility grid
An external connection allows utility energy to be used when available and required for operation or the charging system.
Auxiliary connectionDC architecture without an external solar inverter
The panels maintain a direct DC path to the system. When utility or generator sources are included, they integrate through the control and charging equipment specified for that configuration—not through a conventional solar inverter powering the refrigeration equipment.
Two energy configurations
A 100% DC direct-drive option prioritizes an efficient path from photovoltaic generation to refrigeration. A hybrid option can coordinate solar and backup sources without requiring a conventional external inverter for the cooling equipment.
Designed for transport and deployment
The insulated container, refrigeration equipment and retractable solar canopy create a self-contained platform that can be transported and installed on a properly prepared, level site.
Continuous temperature visibility
Optional remote monitoring records temperature trends and can issue alerts when readings move outside the configured range. This helps Sun Life PR provide better-informed technical support and assists the operator in documenting cold-chain conditions.
