48-12v POWER UPGRADE STILL PRESERVING NEW CARAVAN WARRANTY
This article is designed to give assurance to the reader that upgrading the power system in a new caravan can be done without distrubing the 12V or 240V system installed by the manufacturer. By way of example, an upgraded Avida Topaz is described here.
If purchasing a new caravan, some manufacturers like Avida wont upgrade to Lithium. Other manufacturers are new to Lithium and offer large assembled systems in 12V.
Rule of thumb: if your current is greater than 100A, you are in the wrong voltage!
The 48-12V Hybrid, stored electrical energy from both solar system AND vehicle charging in 48V batteries.
48V Batteries are more efficient, lighter and 35% lower cost than the equivalent 12V. The cabling is smaller as the current flow is 1/4 the size. Typically, the biggest cable size we use is 25mm2
This is the same concept as storing LPG is compressed gas bottles at a much higher pressure, bleeding down through a regulator to the lower pressure used by appliances.
The system creates the electrical power at 48V from the solar panels and vehicle DC to DC charger and store at 48V.
The system then bleeds this power through a 48-12V regulator to the caravan’s 12V battery. This keeps the 12V battery fully charged. The Caravan 12V battery, battery charger is not disturbed. The exception is if it has solar input, we remove those solar input cables and redirect to the Smart Solar that charges at 48V in the new batteries.
The 48V Lithium Batteries are:
We are talking about very high end, high quality smart batteries.
Safiery has written the software interface for the canbus built into these batteries to be controlled by the Victron canbus system. There is NO user intervention with this software, it is plug and play.
The Victron system includes a 3000VA Inverter/ Charger that:
The Solar recommended for this system is to be as close as possible to 1,000W for replenishment power.
The Victron Smart Solar controller shows:
The Simarine gorilla glass display show:
The electrical energy flow and performace is displayed on smartphone:
Installation time for the power system and solar system is far less than conventionional 12V systems and nothing is removed.
The Installed Price for this System into the Avida is Around $12,000 including the 2 x LPG tank sensors and special tank interface for Safiery to BMPro tank senders (plug and Play interface).
Spec is:
Safiery creates power, energy, switching products so people enjoy adventure travel globally on land or water without a genset.
