    Default Saving the crank battery

    My poor Pajero often gets ignored and can stand for a week without being started. I often hook up a trickle charger but this involves a long wire from the house. My mind has started to think about a solar charger. The Pajero sits under a car port so I have a roof that can take a small panel and a post that can accommodate the wiring.

    What do guys think about a small 30W panel and a controller

    I would need 13.8 V for a float charge

    Would it do the job ?

    A quick internet search suggests an outlay of about R1,000.
    Cancel your gym contract and roll out that wire every now and then for exercise.

    If I was not fat, then I would be unpopular.

    I do know that I have some losses on the system.

    Tracker unit

    Dual battery system, if I leave this on the meter, voltage display and controller all will use a little bit and draw that battery down too.

    I am after all thinking of the well being of my prized possession.

    Panel and regulator should do it. 30 or 40watt 18v panel and regulator. Victron blue solat pwm. Should be about 1000.00

    Thanks

    Which is about what I would pay for a half decent charger anyway.

    I wonder if enough would come in to open that solenoid on the NL battery pack. hmmm

    Got two vehicles parked on a 30 watt panel and charger.

    NL will open if the battery is sufficient charged.

    What you need is a smart charger that can be left permanently connected to your battery.
    I saw this one in Cash Converters (see the bargain price on the top)
    If you talk to me nicely (or cross my palm with silver) I'll tell where it is..

    You can always bridge the solenoid with a length of wire that has a, say 10 A, fuse in. Then the power will flow to the aux battery as well. You then remove the fuse when it is not needed. If you forget to remove it, it will blow when you start the vehicle. Did this for many years ......

    Just for the sake of experimentation,

    Pajtu has been standing this week so I wanted to give the battery a bit of charge. I have a small aux box, 50 amp Deltec wet cell. This is not my main aux, just a small one for charging, vape machines, cell phones Sat phone, camera batteries and did I mention Vape machine batteries. As it so happens I also have a wet cell Deltec as my crank battery. HMMM

    I have two 16 mm welding cables running to the back of the car from the crank which plugs into my NL power pack, so I unplug this.

    I then plug this into the aux box on a direct to battery connection

    The aux box has a PWM controller which I then plug the solar panel into.

    Instant success, the early morning sun is already giving 14.2 from the semi flex panel and I can see this going to both batteries
