As I installed several additional items like the hot water boiler. I needed to expand or finalize the means of automatic or remote switching. So the central power distribution rack required an update. Which due to the mounting grid is pretty straight forward. As that allows me to easily rearranging its components without screwing or drilling in any of the interior components.
The Jabsco water pump and Elgena 24V hot water boiler are now switched with a standard 24V automotive relay after being fused appropriately. Preparations for the installation of a Victron Orion DC-DC source are there. Creating a stabilised 24V distribution for voltage critical items like the LED lamps and delicate electronics in the shelter unit.
