Yes. Modern solar TRUs incorporate large battery banks that provide 24-48 hours of autonomous operation. Even in consistently cloudy regions, the combination of daily solar generation and overnight grid charging ensures reliable operation. Systems in Northern Europe have demonstrated 99.5% uptime year-round.
Solar TRUs maintain temperatures from -25°C to +30°C reliably. The electric compressors actually perform more efficiently than diesel units in extreme conditions. For ultra-low temperature applications like ice cream (-30°C), specialized systems with larger battery banks are available.
Current lithium-ion batteries are warrantied for 8-10 years or 4,000 cycles. Real-world data shows 80% capacity retention after 10 years. Battery replacement costs are included in TCO calculations and still result in significant lifetime savings versus diesel.
