FAQ

Q: Can this solar cold room function completely without any connection to a local power grid?

Absolutely. The system is fundamentally designed for 100% off-grid operation. By utilizing a high-yield foldable solar panel array paired with up to 30kW·h of battery storage and advanced phase-change cold storage technology, it maintains precise internal temperatures day and night without ever requiring external electricity.

Q: How does the phase-change cold storage technology protect my produce during extended overcast days?

Phase-change materials act as a highly efficient thermal battery. When the system is actively cooling, these materials freeze and store massive amounts of thermal energy. If power generation drops due to severe weather, the materials slowly release this stored cold, extending the cooling duration significantly and preventing the temperature spikes that cause rapid spoilage.

Q: Is the exterior structure truly capable of withstanding severe outdoor weather conditions?

Yes, the unit is built within a brand-new, heavy-duty 20HQ or 40FT metal container featuring a robust airfoil structure. It boasts an IPX5 protection class, meaning it is thoroughly rainproof and sealed against dust. The exterior is specially treated to resist corrosion, making it highly durable in high temperatures, heavy rains, and coastal environments.

Q: What is the maximum load capacity, and how easy is it to load and unload cargo?

The 20ft model is engineered to securely hold up to 5 tons of cargo, while the 40ft model can accommodate a massive 10 tons. Both models feature spacious 0.8x1.8m double doors, allowing for straightforward, unobstructed access for pallet jacks, carts, and the manual loading of bulk agricultural produce.

Q: What type of maintenance is required to keep the solar and refrigeration systems running optimally?

Maintenance is incredibly straightforward and designed for minimal operational downtime. The primary requirement is regularly cleaning the foldable solar panels to ensure maximum light absorption. Additionally, users should periodically inspect the heavy-duty door seals, ensure the compressor area remains well-ventilated, and check the digital control panel for any automated diagnostic alerts.
