When your adventure is measured not in miles but in moments away from shore power, you need more than just a battery—you need a bold rethink of RV energy. GRECH POWER™ is how off-grid living gets redefined. Standard across the 2026 Grech RV luxury motorhomes, this groundbreaking energy platform merges advanced lithium technology, intuitive control systems, and a suite of integrated tools to create a continuous, self-sufficient travel experience. It’s a system that aims not just to support your journey, but to elevate it, making energy independence the new standard in luxury RV living.
At the heart of this innovative platform lies a powerhouse: the Lithionics® 51V lithium-ion battery system. Delivering an impressive 16,896 watt-hours (Wh), this system provides enough clean, quiet energy to run the rooftop Gree A/C for up to 14 hours—no generator required. It’s the only UL 1973 Certified lithium-ion battery offered in the RV market, bringing not just muscle, but superior safety and reliability to your luxury motorhome.
What truly sets it apart? Efficiency. This next-gen 51V platform recharges up to 50% faster than older 12V systems, allowing more time for adventures and less time waiting for a full charge.
Lithionics’ NeverDie Battery Management System surpasses conventional power regulation. It’s equipped with an external BMS, Advanced iONbus® communication, and a built-in NeverDie® Reserve that safeguards against deep discharge damage. And with the Bluetooth™ Battery Monitor App, you gain real-time insights into your battery’s State of Charge, State of Health, and remaining life—all from the palm of your hand.

Replacing the former Firefly system, Garmin SERV+™ is now the standard in every 2026 Grech model. This intuitive house control interface combines Bluetooth and Wi-Fi connectivity, giving you complete command over your RV’s functions through your smartphone or tablet. Climate, lighting, diagnostics, tank levels—it’s all at your fingertips.
Off-grid doesn’t mean off-the-grid. With GRECH CONNECT™, you gain access to real-time remote diagnostics and support. This Wi-Fi-enabled system lets you monitor performance, receive over-the-air updates, and connect directly with technical experts no matter where your journey leads.
The ARCO Zeus alternator system redefines in-motion charging. With high-output performance even at idle and Bluetooth-enabled monitoring via its app, Zeus ensures your batteries remain charged whether you’re cruising scenic highways or parked for a remote overnight stay.
A Victron 3,000W MultiPlus-II Smart Inverter ensures intelligent, silent power conversion. This robust inverter supports both AC output and battery charging, all managed via the VictronConnect App for real-time diagnostics and remote access. It’s dependable, smart, and engineered for the ultimate RV experience.
GRECH POWER™ includes a roof-mounted solar panel system, offering passive charging that helps maintain battery levels. However, it’s important to note that this is a supplemental, trickle-charge system. Solar alone won’t fully recharge your batteries. For meaningful energy replenishment, you’ll need to drive the vehicle, idle the engine, or connect to shore power. Even so, solar remains a helpful keyword and a valuable feature for boosting efficiency during off-grid stays.

Remote doesn’t mean disconnected. With integrated Starlink Roam satellite internet, you can stream, work, and communicate from nearly any destination. It’s an essential inclusion for those embracing digital nomad life or simply wanting peace of mind while off-grid (Starlink service not included).
Yes—and then some. It answers key questions for any off-grid enthusiast:
What GRECH POWER™ doesn’t do is promise the impossible. There are emissions when using the diesel heating system or charging by driving. Solar is helpful, but true independence comes from harmony—battery, alternator, inverter, apps, and yes, your own habits.
Whether you’re RV travelling in the Rockies, coasting through the Mojave, or tailgating at elevation, GRECH POWER™ brings consistent, safe, and intelligent energy right to your wheels. In a world where going off-grid used to mean giving things up, this system proves you can have it all: power, performance, and peace of mind.
This isn’t just a cutting-edge feature—it’s the core innovation that now defines every 2026 Grech RV model. It represents their commitment to reimagining energy solutions across the entire luxury lineup, from the agile Turismo, to the versatile Terreno, to the expansive Strada.
