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?Sartor wrote: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 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.....ggreenie wrote: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.
N80 in Australia are now made in ThailandSartor wrote: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).
