1) Installing an inverter system in trucks allows drivers to power electronics and appliances without idling the engine, saving on fuel costs and reducing emissions. 2) Idling engines is inefficient and wastes fuel, but drivers idle to power devices; inverters eliminate this need. 3) The document provides an example payback calculation for a fleet of 5 trucks, estimating a cost savings of over $112,000 over 3 years by eliminating idling with inverters.
