RV PROFILE
One of Wonder Roo’ s hallmarks is how and where it locates much of the electrical equipment. If you look inside the tunnel boot on the nearside, you’ ll find a 5000W inverter mounted behind vented Perspex to keep it protected, while the same material is found on the offside to protect fuses and other sensitive equipment. The rest of the electronics are housed within an offside compartment with a filtered air vent.
Now, this is in fact a 48V system. Paul in particular knew what he wanted, and understood the advantages of 48V in comparison to 12V. The wider Australian RV industry is still catching up in this respect, but Wonder Roo was on the case. The lithium battery system provides the equivalent of 864Ah, while on the roof there is a heroic 1000W of solar to charge the batteries via the 40A 48V solar regulator( equivalent to 160A 12V).
There are a host of advantages to running a 48V system over 12V, but the one that’ s mostly applicable to vanners is the efficiency factor. Current is directly proportional to voltage and inversely proportional to resistance. So an increase in voltage increases the current( as long as the resistance is held constant).
