Do you have a circuit diagram together with details of the equipment used, as I am considering something like this for a Trailer conversion to an Incident Support Unit for a Response organisation NormanD WE191

Thanks all for the positive comments
.
It is indeed surprising how much room we have on the inside 
We just made a 450km round trip from Antwerp (B) to Aachen (D) with a stop at Baraque Michel, the 2nd highest point of Belgium (674m), while the odometer just hit 40.000 km .
Fuel consumption was 26.6 MPG, which is not too bad I think. I do, will post more details tomorrow  Peter,

With a little bit of delay, some more details on the electrical system that I've designed and built into my camper:
Charging of the Lithium batteries, also when driving, is done through the mains chargers. This way, the lithium batteries are always ensured of optimum charge conditions. For this purpose, I've connected a Victron 1200VA inverter, over a Cyrix voltage sensing relay, to the starter battery, which is located under the driver seat (LHD Defender).  This inverter produces a pure sinewave at 230V AC. Using 2 x 1mm˛ cable, this power feed is combined with the mains connection through a priority switch. The priority switch prevents accidental connection of the inverter output to the mains, e.g. in case the engine would be started while still connected to the grid at e.g. a camp site). Mains connection is through a compact and waterproof connector:
The actual battery chargers are each rated at 25 amps, resulting in a total charge current of 50 amps, either from the alternator or from the grid.
In addition, I also installed two solar panels of 275Wp each (Kyocera, made in Japan ). These are wired in series (minimum copper losses) and feed into a 60A MPPT solar controller.
A couple of days ago, when we finally enjoyed some sunshine here in Belgium, I measured a charging current of 45 amps from the MPPT. Not bad at all ! A few amps more than expected, but Kyocera is conservative in its specifications and the outside temperatures are still rather cool, which also helps. Since the solar panels will also function while driving, total charge current with the engine running can amount to around 95 amps, under ideal conditions. In reality is will rather be between 50 and 70 amps, all depending on whether conditions. Both the mains chargers and MPPT solar charger are combined in a high current fuse box:
Since all parts in this installation are connected via CANbus, also the fuses are individually monitored. On the control panel I will get a warning in case one of these fuses might fail. The common connection on this fuse box goes to a second fuse box, which holds the individual fuses to protect the Lithium batteries and their wiring. The Lithium batteries are amazing. Light, very compact and store a huge amount of energy. Unfortunately they are also pretty expensive 
As this is a very compact camper, like most Defender conversions, lead-acid batteries of this capacity simple were no option. Far too big and too heavy. If all goes well, these lithium batteries should outlast the lifetime of this camper ... time will tell. Click image to enlarge Each battery is fitted with a special protection relay which is controlled by the battery but also through the CANbus. In case of a hard failure, deep discharge or potential overcharge, the battery will be disconnected to prevent further harm. These relays are supplied by BlueSea and have a continuous 500A rating (like the batteries themselves). Click image to enlarge Except for the induction cookers, all other equipment is powered directly from 12 Volts. There are no switches, as everything is connected to this digital switching module which in turn is controlled from the touch screen control panel.
Every connection on this switching module has a 10 amp rating - fused with 15 amp. Current protection can be programmed also at a lower value, from as low as 2 amps. When an output is used for controlling lights (LED or halogen), a dimming mode is also possible, which is nice to save energy. The control panel allows access to virtually all functions that are possible on this system, although programming via a laptop is more convenient. . All in all it's a nice piece of kit, quite elaborate but also rather unique I think Peter,

All I can say is wow.
Makes my weekend project of adding in a second battery look a little Heath Robinson |
