Off Grid Living
Quiet, efficient and non-polluting solar power has been a cornerstone of EarthRoamer design since 2000 when an early EarthRoamer prototype (the ER2K) was built. At a time when few, if any, RV’s had more than 10-20 watts of solar power and most had none, the ER2K was built with an unprecedented 170 watts solar panel array. By the time the original XV-LT was launched in 2003, solar technology improvements and the larger roof area of the XV-LT enabled us to provide 510 watts of solar power. Today with continued improvement in solar panel technology, the EarthRoamer LTi comes standard with 1,320 watt of solar power.
The benefits of an inexhaustible power source that works from sunrise to sunset are unlimited. With our large solar panel array, the LTi can accumulate a significant amount of power – even on overcast days – and keep the battery bank topped off. The vast solar panel array easily keeps up with the high efficiency refrigerator which means that as long as the EarthRoamer is outside and exposed to daylight, you can keep the fridge stocked, and fan or heater running for extended periods of time without needing to be plugged in.
Power produced from solar, the engine driven alternators, and shore power is all stored in an 11 kw lithium ion battery bank. These highly advanced batteries are completely sealed, long lasting, have low internal resistance for fast charging. They are durable enough to holdup to vibrations and off-road use. The benefits of switching to lithium ion battery banks from the previously used AGM are hard to ignore – higher energy density, low maintenance, and self-discharge capabilities make these batteries the perfect addition to an expedition vehicle that needs to be able to do it all.
