Grech RV is proud to introduce GRECH POWER™, our most advanced and intelligent energy system to date – now standard on all 2026 model year Class B camper vans. 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.

Whether you’re exploring national parks, boondocking in the wilderness, or simply seeking more freedom from shore power, this system provides the ultimate off-grid adventures.
GRECH POWER™ is more than a power system – it’s the future of luxury RV energy, this platform underscores our relentless pursuit of innovation, quality, and the freedom to explore – uninterrupted.
