Electrical System
Batteries
The Simpson is fitted with 2 x 100 Ah Lithium Iron Phosphate Batteries. These batteries have an
integrated BMS to prevent accidental damage to the batteries. Included is an activation cable, should
the battery become discharged at or below 10 V, connect the camper to a power source and press
the button on the activation cable to awaken the batteries. It is only required to activate one battery,
and this will awaken both.
Battery charger
The Simpson comes fitted with the Projecta 25 A battery charger. This is solely a 240 V charger; it will
only work when the camper is plugged into shore power. It will come preset, there is no need to
change the settings in the charger.
For all charger instructions, please see the manual in your camper or here

Solar
The Simpson comes with a 200 A free standing solar panel. This is designed to plug into the Anderson
plug on the drawbar. It has a built-in solar regulator and is plug and play.
There is a circuit breaker for the Anderson connection in the rear cupboard, above the water tank
change over valve. If the solar panel does not recognise or charge the batteries, check this breaker
to ensure that it has not tripped.
Mains Power
The Simpson comes standard with a 15 A input on the side of the camper to allow mains power to be
connected directly to the electrical system. This 15 A input has a larger earth connection than a
standard home plug and requires the use of a specialised 15 A extension lead which will have the
larger earth pin on both ends. If connecting the van to mains power point where a 15 A power point
is not available, you must use a 10 A -15 A adaptor with safety switch. These are available from most
camping or hardware stores.
240 V mains power is lethal, failing to use an adaptor can result in serious injury or death.
