Microwave and big inverter on N80

Does anyone use microwave or similar high power appliance on the n80? Do you use a big 2nd battery (200ah+) or turn the car on and link main/axi batteries when using these big appliance?

Is there any dcdc charger that has direct link function of main/axi batteries or you just use a 3 way switch to connect both batteries when you need to?

Thanks

I believe this would be more suitable for electrical section.

However, here is my take: for invertors I'd recommend having a secondary battery with higher discharge rate (higher charge rate respectively), especially when you are looking at high power appliances (at least 2000W). In this case, depending on other items / consumers you are looking to have at least 100Ah battery. In this case, I'd recommend having a quality 12V DC-DC charger such as RedArc BCDC1225/BCDC1240/BCDC1250 (note that there is a version with solar input for these). If you are in Australia, then you can check other brands such as EnerDrive (I am probably biased as there is only CTEK and RedArc in EU and I am a dealer for the Balkans for RedArc which I am happy with).

There is a possibility for a setup to link two batteries (starter and aux) together. This could be done via a voltage sensing relay such as RedArc's SBI: here is a diagram for that https://www.redarc.com.au/bcdc-dual-wit ... tery-setup (in addition, here is a video of such setup: https://www.youtube.com/watch?v=SgBc249DbwQ).

I really don’t think things like that belong on rigs like a hilux etc. The powers demands are too high to justify. The battery and inverter required would be huge, they’re extremely bulky and really just an unnecessary luxury.

Buy a 12v Microwave, it would be cheaper. They are lower wattage so cooking is a little longer.

Thanks mate, so with the Hilux kind of alternator I do need a voltage sensing relay like the sbi or I can put a 3 way switch to link both batteries when needed straight away?

Also I'm not sure what's the output of hiluxs alternator, if it will supply enough power to the big inverter, thanks

I just need mw on the work truck to heat up lunches for me and the workers. I've run one on an Amarok for couple years the Amarok has a fixed voltage alternator so that's much more straight forward setup.....

To my knowledge Hilux's alternator is 80A. I think we had some modifications in EU in the early versions with "improved alternators" which were 130A, but I will need to check (EU Hilux is build in South Africa, while Australian one is coming from Japan).

For the Hilux installation I'd recommend to go with SBI. You can install a momentary or rocker switch to link both batteries when needed (check the diagram and the video above).

This one is 40A at 24Vdc. You could use a big dc-dc converter rated at 100A or thereabouts, or run a pair of batteries in series and charge them with a specialised 12-24Vdc converter if one exists. Not a cheap exercise though.

Might be easier to use a small 240V microwave and an inverter generator? The generator would be useful for other purposes too.

N80 in Australia are now made in Thailand

I run a 2000w Projecta inverter from 2 x 105ah Full River AGM batteries out the back of my Hilux without issue. I only charge batteries and use a coffee machine from the inverter oh and missus will use her dryer to.

You will need a DC to DC charger to charge your batteries as you drive which also acts as an isolator so it doesn't flatten your crank battery.
