Uuuummm do you mean 20 Watts. 200 Watts is about 18 Amps. The BD50 Compressors won't use that much... or are you talking a days useage. If so it is easier to talk in Amp/Hours

I would budget that you will be using about 3 A/H on the big 95 Frig during the day Ross and about 2 A/H over night. You should be under those figures but thats what I would use.

That means about 60 A/H to find each day to replenish batteries which you should do easily with about 4 hours on Genny and a small Charger of 6 to 8 Amps capacity if that is your plan. If you have the Frig on the genny while it is running and do longer than 4 hours (but who wants that at Cape Riche) you won't need much battery recharging at all.

I've got 2 x 35w continuous amp Anderson fuses that I really need sorting out this week so I can hook the fridge up for 'Travelling Mode"

I've also got a 750w generator that I'll be using during daytimes as a temporary fix. It only takes 200watts to run the the Evakool.

I'm open to any suggestions. U got any pics to show, for ideas?

Put your frig on one of the 8 Amp outlets Cobber... 8 Amps is way more than you need and they are a "Merit" Connector on those Telstra Rigs aren't they which means it is easy peasy DIY for Plugs.

200w is what is says on the converter that goes inbetween the plug in the wall and the fridge. I'll have a good read when I finish work. Thanks.

nowoolies

ill take a few pics in the morning and post them my sub board is similar got a couple more outlets i modifyed about a year ago
some tosser nicked my solar panels i have got a couple on order with one of my suppliers supposed to be half the price you have
ill check that out as well ,i forgot about the panels, mine dissapeared when i had the prang. evreything else is still there.
are your door hinges made of some sort of plastic like mine if so check them over, mine cracked and fell off at christmas hit my son in the head with the door hahahha to far from his brain to hurt him. hes 27 ,
no sign of letting go untill they fell off, the hinges are $100.00 ea the rivits are about $2.50 ea and the rivit gun is $190.00 i now have the rivits and the rivit gun if needed for loan by anyone.

I run twin 38 ltr engels ,1 as freeze set at around 3.5 on rotary dial other as fridge set at just under 1 on rotary dial. All camp & vehicle lights are led so power usage is as follows:
1 fridge & freezer together 3.1-2 amps per hour at a circulating rate of approx 60-65%
2 led lights ,all interior led's including map-surface mount & roof console consume 1.1 amps with external tent & flood led lamps consuming 2.2 amps, total consumption 3.3amps.
3 pump for shower is non existent as car is running to opperate heat exchanger
4 150watt inverter consumes 8.1 amps but we normally only use this when driving or for a couple of hours through the middle of the day

Total average consumption per day approx 66.4 amps per day.

80 watt solar mounted to roof rack pulls 6.9-7 amps in full sun [approx 4 hrs of day] & around about 3-4amps for the remaining part of the day.
Approximately 52.5amps per hour, meaning a standard 100 amp hr deep cycle battery[ 80% of usable power] gives you 80amps which is approx 8 days before needing to be charged.

I know there's alot in this post , hope it helps you rosco & anyone else.

Note: I have an advanced battery monitor that tells you amps used, charge in , time to discharge & time to charge.

Come on mate, i'm a dumb building tradie & i get it. Took me a long time to learn it all, thanks to mates for percivering with me. It all boils down to amps out & amps in.
The crux of it is SOLAR WORKS.
