The electronics are the heart of a camper trailer designed to be independent of mains power, and should not be overlooked when in the pursuit of freedom from caravan parks. They are also a main reason our campers cost so much, as money must be spent to have a quality system. Although the technical nature of electronics can be confusing, fundamentally it is all about keeping the fridge cold and the showers hot. Aussie Swag Campers has put together a system of quality components that is easy as possible to operate.
Our latest models use a 200 amp hour Lead Crystal battery which is enough for three to four days camping without recharge. However, in situations where there has been several days of bad or even cloudy weather or in shady campsites, the solar panel will not supply enough power to recharge the batteries and a generator becomes the quickest and most efficient means of recharging. As such, Aussie Swag fits as standard a 60 amp 240v charger and high quality, low resistance batteries to allow the fastest recharge times possible.
A 1600-watt pure sine wave inverter is standard. The inverter allows 240-volt appliances such as laptop computers, media players, TV and mobile phone battery chargers and coffee machines to be operated via the trailer battery pack. The inverter is hard wired to the 240v outlets and automatically switches between mains and battery power.
The 150 watt solar panel (standard on the Ultra) can charge the battery pack when 240 volt power is unavailable. The DC-DC MPPT charger ensures the batteries are not overcharged. The panel is stored on the fridge box and charges in its mounted position, but when camped is better put out in the sun (most people camp in any available shade) using a 15m extension cord and security cable. The panel stands up using two twist lock anodized aluminium tent pole legs and can charge up to 10 amps an hour in ideal conditions. On a clear winter’s day a more realistic charge rate would be 7 amps an hour. Running the Waeco CFX95 fridge/freezer, lights and water pump can use roughly 60 amps a day (this figure varies widely depending on usage and conditions), so a panel facing the sun for 7 hours a day almost has this covered.
