Hi all
With my 80 litre frige, the 240 volt power supply has 3 power options on the front. From my comprehensive (not) instruction manual, the ciggie plug is obvious, plug frige in here. There are a +ve and -ve screws called 'battery'. My interpretation is you can wire a 12 or 24 volt battery supply here for providing power when there is no 240 available. The other +ve and -ve are outputs (from what I can work out) for hard wiring the fridge instead of the ciggie plug. The instructions state the output is 24 volts to both the ciggie and the 'other +ve and -ve screws when on 240 volt, and switches to the battery voltage when 240 volt is available.....makes perfect sense???(both my wording and the instructions)
Has anyone tested this in the real world, as I am considering mounting the 240 volt supply in the car and hard wiring everything. At the moment, I unplug from the car and plug into the power supply box when 240 is available, but It would be better if it was a bit more permanent and automatic......
This is coming about because I will be joining the genny brigade......ok away you all go lol.......It will be a 2 stroke cheapie as
well.......away you go again! Last
camping trip I borrowed one and it was really good, used half a litre an hour, and was running The fridge (about 65 watt I think), and the best thing was a cheap twin flooodlight on a tripod I got for $35....One globe removed. It was so good to have a lot of light from an elevated position 20 metres away from us, the bugs went to the light, which was far enough from us for a change! We couldn't hear the gennie which was about 40m away, It just made it easy!
Cheers Andrew

LOL - I had a chuckle as I was writing, I also drive a 2.8 nissan....leaving myself wide open. The boat motor is a Honda though, its very hard to take any criticism of the BF 90 seriously, except the weight.

The Mobitonics power convertor you are talking about is the MPS-50 ?
C- C+ go to the fridge and B- B+ goes direct to battery , you got that bit correct , however do not under pain of having to replace the whole unit plug the 240v plug into a "cheapie" gennie for long term use , as the fridge cycles on and off the gennie hunts and creates power surges in the Mobitronics , smoke soon follows , better to still run the fridge thru the battery and use the gennie and a batt charger ,

Thanks for that Axel....While the gennie is on the fridge doesn't cycle, and will usually be running a 500 watt light as
well so it shouldn't be too bad. Maybe the battery charger needs to be upgraded and forget the MPS-50 in the car, and leave it in the shed for beer chilling purposes between trips. (I have a beer frige on the deck, but its a long walk from the shed (20m)......do I have a problem?)
I do have a surge protector, but it may not give that much protection (it also was cheap).
Cheers Andrew

I'm with Axel..... Use the genny on a charger and leave the fridge on 12V... And as you say leave the mobitronics at home to avoid the risk of injury walking so far to the deck!
Or before someone else tries to come up with the complicated way I'll give it a bash....
Run the gennie with a REALLY good quality battery charger (read expensive) then buy a REALLY good pure sine wave inverter (again make sure it is the dearest) to run the mobitronics through... Then of course you'll need 6 AGM batteries of the most expensive ones you can find running through 2 rotronics units and don't forget to completely rewire the car through the rotronics unit so you don't get a flat battery! (I'm sure someone will out do this with a more complicated version.... perhaps add 24v to the system somewhere!)....
Of course if your main battery went flat you could always use your gennie and battery charger to give it some more juice!

Thats one of the reasons I'm going the gennie way....I'm usually on my own and a charging option would be a bit of insurance.....I may buy a better charger instead of the Kmart one I have now. I just need to make an easily removable box/bracket ro put it in the tow bar hole so I don't have petrol in the car!

Is the towbar just for whilst
camping?
Could be a little dangerous if someone rear ends you otherwise... between your hot exhaust, tail lights and their hot engine... could end in tears. Not sure how that would sit legally/insurance wise either. For the small amount you'd need to carry yu might be better with a small
tank underslung or if inside the vehicle perhaps a fuel cell style used for drag cars etc (could be $$$$ though, local drag club would be able to help) then vent it to the outside so you don't get the fuel smells unless it is spilt filling.
Or can you perhaps make a couple of holders for smaller jerry cans around the roof rack somewhere.. (not sure how much space is left with the roof top tent) might be better with say 2 5L than one bigger one.
