    That’s looking better switching to Lithium

    312w from 3 x 120w semi flex panels.

    I’m happy enough with that……assuming it’s repeatable.

    I did manage to ding one during installation switching to Lithium

    Managed to get to float and 100%, had MacBook running off inverter most of the day along with modem running off USB, plus the fridge freezer

    Plenty in the tank for some induction cooking….

    21 days into our lap…….and

    Thought I’d have a looksee at the history as I’ve barely been bothered to check SoC.

    The only regular check I do is a quick check to confirm DC-DC is doing its things each we hit the road….

    The only history I can look at is the Victron solar controller, which is a fairly basic way of looking at the system.

    Either way there has only been 2 days when the solar controller hasn’t gone into float……however battery is generally showing 100% SoC at some stage during absorption like today….

    I did spot the SoC at 62% one morning.

    Highest Solar output so far has been 290w….but mostly in the low 200’s

    So far, the upgrade to lithium seems to be working just fine….ye olde AGM’s are a distance memory.

    As we get more into the trip we will be doing more multiple days parked up which will test our storage capacity.

    Hi W&KO and good to see you're finally "off" I've been following your electrical build with some interest and what I find really interesting is that although our vehicles and electrical requirements are very different our electrical build is very similar.

    Oka 800.jpg

    Oka 413 has a 200 ah LiFePO4 'house battery' (2 X 100 ah) and 2 solar panels with a stated capacity of 220 watts each though like most (all) eBay solar panels grossly overstated. I would suggest 160 watts would be a more realistic 'best case' figure for a theoretical maximum of 320 watts. The most I've ever seen is 260 watts. There's a Votronic 430 watt MPPT controller and a 30 amp Votronic DC DC converter both with Lithium profiles. A Victron 240 volt 30 amp (Lithium) charger and a Victron 500 watt inverter rounds out main hardware. A Victron BMV 702 with Bluetooth dongle provides monitoring of battery SOC and voltages.

    As I said, hardware wise very similar to your Landy setup although the only load on the house battery is a very efficient EvaKool 146 litre upright fridge/freezer (50 watts) and the only use for the inverter is the Stihl chainsaw battery charger.

    Oka Power Panel.jpg

    We gave LPG away several years ago as it was just too hard. Bottle filling/change over/dust in jets and regulator issues when on the road was just a PITA The best thing we ever did was ditch the LPG and go with a metho yacht style 2 burner stove. We have a butane disposable cartridge stove as backup and inside use but bloody useless when below around 10 degrees C. Not for everyone but simple, well built with cheap and readily available fuel, slower than gas to boil water (flat out) but always works
    I gave induction cooking a look but the current/power levels required and the dimensioning/build put me off as did the inherent power losses when running 1-2 Kw appliances from 12 volts.

    Cook 3.jpg

    A close look at 'The Cook' will show that she is cooking with a large frying pan, a medium sized pot, a kettle and a small frying pan all at the same time on our 2 burner metho stove. This would be impossible to do on an induction stove as by their very nature all heat is inside the pot so slow cooking/simmering 'on the side' would not work. Kaye's disappointment and frustration at being unable to simultaneously cook three courses at the same time would be most profound and it would be very unfair of me to subject her to this torment Seriously though, Kaye enjoys the challenge of cooking complex (to me) meals on our two burner stove so (for us) an induction cook-top would be a major backward step.

    Keep up the commentary when you can, a very interesting and informative thread.

    We are getting very good at one pot meals……we just don’t have the space.

    There are times I’d like a second induction cooktop, but it’s not often at all.

    Hopefully the info helps others……..I’m far from an expert can post real life testing and use and what I see on instrumentation.

    When we are parked up for a few days I’ll get a better idea.

    Have certainly enjoyed reading the thread and following you exploits with it all.

    Sooooo………how’s the system actually performing in the top of aus now that we have slowed up a bit and not driving as much.

    Well we are getting by…..last two days we didn’t get back to 100% switching to Lithium

    First day only got back to 75% and the second back to 85%, this included a small drive to a new camp site that had better access to the sun for harvesting.

    The second day we might not have used induction but did you the travel Buddy oven to cook pizzas….not quite as punishing on the battery capacity.

    We pretty much only cook one meal a day on the induction cooktop……..which can consume anywhere upto 20%

    Things that are different from all the testing I did at home.

    We are now running the fridge as a fridge/freezer, previously we only ran it as a fridge….this mean the fridge is cycling more

    Day temps are higher, haven’t been below 30 degrees during the day, closer to 40 than 30 therefore fridge is working harder

    Night time temps are also higher, again fridge is cycling more often, we know this as we literally sleep right above the compressor.

    With the higher night temps we are now running a 12v fan all night…

    Charging more devices, camera and laptop mainly.

    May need to purchase a solar blanket…time will tell given to gifted our solar blanket to no. 1 son in an effort to save space.

    I fitted a 3rd semi flex solar panel but it gets shaded by the bag we have strapped to the roof, maybe normal fixed panels would perform better.

    Still happy we ditched gas…

    A little update…….

    When I posted the previous update we had noticed the fridge was cycling on longer…..

    Well this continued to get longer and longer and than fridge wasn’t pulling down to -14

    Turns out I should read owners manual 4 years ago when I purchased the fridge.

    Anyways one should clean the condenser…….as per instructions, always it a mission to remove the fridge.

    Big shout out to Flick refrigeration on Kununurra for squeezing us into their fully booked day. They also installed a connection so that pressures can be checked in the future.

    Fridge is now back to cycling as it always has…..

    Got a picture of the connection?
    Some types like to leak later on.
