No Noisy Generator
EarthRoamer XV-LTs are designed from the ground up to not require a typical RV style generator. Typical RVs and expedition vehicles use a separate stand-alone internal combustion engine powered generator (RV generator) as their primary power source when they are camping independent of electrical hookups. Typically these RV generators are fueled by gasoline, propane or diesel.
There are many reasons that EarthRoamer XV-LTs are designed to NOT require a traditional RV generator for stand-alone operation including:
Noise – RV generators are loud
Size – RV generators take up a significant amount of space
Weight – RV generators are heavy
Alternate Fuel Required – Gasoline and propane fueled generators negate the advantages of an “all diesel” Xpedition Vehicle
Service and Maintenance – Adding an additional internal combustion engine driven generator means an additional complex system to service and maintain
We order Ford F-550 turbocharged diesel Power Stroke trucks with the dual alternator option which provides a quiet, fuel efficient, factory installed 3.7 kWh generator. We install an advanced battery isolation system and connect the factory alternators using low resistance, #4/0 tinned copper marine cable to the massive absorbed glass mat (AGM)camper battery bank. Whenever driving or the engine is idling, the AGM battery bank is being charged by the high output dual engine alternators. At idle, the Power Stroke diesel burns approximately .5 gallons of diesel per hour which is significanly less than many RV generators at full load.
The new Power Stroke is incredible quiet – this is from a Car and Driver review:
…the diesel is remarkably quiet. Hardly any clatter or turbo noise is audible, and the interior is actually quieter than in the last Lexus we tested. At wide open acceleration the Ford measures 69 decibels (emphasis added), five fewer than a Lexus ES350; and even cruising at 70 mph, the F-250 is a hushed 66 dBA compared with the ES350’s 69.
Combined with our standard .88 kWh (or our optional 1.1 kWh) solar panel array plenty of power is provided for standalone camping in an EarthRoamer XV-LT without the need for a noisy RV generator.
