Challenge
Flat batteries from high electrical demand during rest periods were causing breakdowns, costly callouts and reduced vehicle availability.
Solution
165 Wp systems on semitrailer tractors and 380 Wp systems with inverters on box vehicles, installed in-house after training from Green Energy.
Outcome
Flat batteries eliminated. Drivers report significantly longer runtime for refrigeration, air conditioning and heating. Fewer service callouts and improved vehicle availability.
TESTIMONIAL
“The feedback from our drivers is consistently positive. The fridge can now run over the weekend without the battery being flat on Monday. The air conditioning and stationary heating also run for longer.”
