Grech RV’s 2027 models will feature upgraded power systems that the Type-B manufacturer said deliver greater battery capacity, faster recharge capability and extended off-grid runtime.
Grech RV Vice President AJ Thurber said the company made “significant advancements” to its Grech Power energy platform and created the Grech Power Max and Grech Power Core systems.
“At Grech RV, power is no longer just a system — it’s the foundation of the entire ownership experience,” Thurber said. “With our 2027 Grech Power Max and Core platforms, we’ve created a fully unified digital ecosystem that delivers more capacity, faster charging and intuitive control — transforming our vehicles into true off-grid smart homes on wheels.”
The new systems were developed in collaboration with Victron Energy.
The manufacturer said its Grech Power Max increases 51-volt lithium battery capacity from 16,896 watt-hours to 20,480 watt-hours, an increase of 21%. The system offers up to 16 hours of continuous A/C runtime, depending on conditions and usage.
The Grech Power Max will be featured on select 2027 model year Strada-ion, Terreno-ion and Turismo-ion units.
The Grech Power Core will be standard on select 2027 model year Vacanza-ion units.
Grech said the Power Core increases battery capacity from 8,448 watt-hours to 10,240 watt-hours, also a 21% increase. It offers up to eight hours of continuous A/C runtime, depending on conditions and usage.
“As part of this evolution, Grech RV is transitioning to a Victron-based battery ecosystem across 2027 model production moving forward, further unifying system integration, performance and user experience,” a Grech RV spokesperson said. “The Victron Energy lithium batteries utilized within the Grech Power Max and Core systems are UL 2054 certified, reinforcing safety, reliability and compliance with rigorous industry standards.”
On the charging side of the system, Grech said it uses the ARCO Zeus high-output alternator and regulator.
“A key component of the Grech Power platform is the integration of the Garmin SERV system, delivering advanced house control system,” a Grech RV spokesperson said. “In combination with Garmin EmpirBus digital switching, this enables a fully integrated control environment across all critical RV systems.”
Grech said authorized dealers can provide details, availability and model-specific equipment.
