The RoadSeo is a special version for use in vehicles with an 24V inverter. The RoadSeo works on inverters of the “modified sine” type. This is the most common type of inverter. A 1000 Watt inverter is sufficient (and very affordable). So no expensive pure sine wave inverter is needed to connect the RoadSeo to a battery. The RoadSeo is mainly used in trucks, but is also very suitable for campers and boats.
