Designed for true off-grid independence, GRECH POWER™ delivers clean, quiet, and powerful lithium-ion energy, setting a new benchmark in the Class B market. At the core of GRECH POWER™ is the industry-leading Lithionics® 51V lithium-ion battery system, delivering a remarkable 16,896 watt-hours (Wh) of energy – enough to run the motorhome’s rooftop A/C for up to 14 hours on battery power alone. Lithionics® 51V batteries are the only UL 1973 Certified lithium-ion batteries available to the RV market, offering industry-leading safety, reliability, and performance.
