    Not much to report...it just seems to work

    No longer worried about capacity.....still haven’t been below 68%. No more checking volts and checking solar.

    Inverter remote on/off is now mounted into the cupboard and the 240v outlet is also mounted, no more dangling on the end of there leads

    @ 96% this morning.....cloudy at the moment will see how long it takes to get back to 100%

    Weekend just gone was the biggest test for the system.

    It cloudy and raining at times and other times had full sunshine.

    Sunday morning our battery was at it lowest 52% using induction cook top a bit and 12v running flat out for 4hrs in the 12hrs prior.

    Saturday I hit a new record for watts out of my semi flexible panel

    Sunday they produced more than they are rated for.

    I had me doubts about semi flex but having a couple of quality ones I’m more comfortable.

    Next big discussion point is charge rate if you only drive short distances.

    We left this morning with battery at 68% at 5:30am and had a 1hr10min drive to next location and than it’s been solar only, battery was at at 99% when I checked at 10:45. Replaced 84amp, fridge running and battery is tossed up.

    My alternator charging is restricted to 40ah and I only have 240w of solar.

    Overall pretty happy and should suit our touring requirements. Sure I didn’t get fully charged yesterday but sat and today we will be at float.

    switching to Lithium

    Meant to add, we didn’t chase solar yesterday...panels were facing to the east all day.

    Weather on and off bad so we laid in bed watching movies most of the day.

    Hi W&KO, I am not seeing your point?

    You are achieving nothing more than what you would achieve with lead acid batteries.

    What are you trying to point out?

    switching to Lithium

    Well that went down like a lead balloon drivesafe.

    Surely there is more to the system than just the selection of lead vs lithium batteries.

    Good work W&KO - thanks for sharing the details on your system set up and the results you are getting from it. switching to Lithium

    It’s an interesting thread.

    I currently have 115w panel on my camper (the high end semi flex 4x100w all crapped themselves a while back) and 2x105ah AGMs....

    I’m seeing those charging figures as above with this set up.
    Once my second 115w panel goes up I’ll never have an issue.

    Not sure what you mean. It’s sharing my journey as it might help others decide on a solution.

    I’ve close enough to tripled my capacity for the same weight as my old set up. And yes I’m tight on weight. My 40ah charger plus a bit of solar has the legs for short drive days. We have two years to do our lap so I’m guessing there will be plenty of short hops and multiple days stationary. I normally try and park facing north, but this weekend views was more important than harvesting solar. I suspect there will be many time I won’t have to option to point the car in the preferred direction.

    With my old set up I would have been fussing around watching volt levels,chasing solar, dragging out solar blanket or running the engine instead of enjoying time with the bride and friends. I would probably not have had a roast dinner either. Along with less storage space and would be using precious load capacity.

    Old v New......no comparison.

    All good W&KO. My comment was directed at drivesafe. It seems my own comment went down like a lead balloon....heh heh....sorry about that.

    I fully get what you are trying to achieve and the point of this thread, and also why you chose lithium batteries.

    Keep up the great work and keep sharing. Cheers.

    The very reason I enquired about W&KO's power usage and recharging figures.

    Regardless of what type of batteries are being used, the same setup would give you the exact same charging capability for lead acid or lithium.

    Hence my enquiry, what are you trying to show?
