    Default Real world application debate

    Thanks to Fluffy and Eggie or if you prefer Eggie and Fluffy for their input on the electrickery.

    So just to separate a debate from the main thread I am inviting members to put forward their real world applications to see what best suits.

    I will start. I have a vehicle with a dual battery box, internal solenoid. Wiring from the crank to the aux box. The requirements are to power a 50L Waeco fridge.

    There is also a trailer with a Bundu top tent that requires 20 sec bursts to lower and raise the tent.

    There is a separate battery box that is used for led lights around camp and to charge e readers cell phones camera and laptop batteries as well as the 18650 vaping bateries.

    A 100 w semi flex solar panel is available and each battery box has a PWM controller attached.

    What batteries would you use ?
    What chargers ?
    Lusted for a Landy but the Pajero was sexier and bigger in the right departments, just like my Missus.

    I'd say you need to give more info.
    To calculate your needs, you need to supply details in watts usage.
    Any answer without knowing those variables would be guesswork.

    I suppose one could extrapolate that info from what you gave in the OP... but giving it would make things easier.

    4 years ago I was the noobie. I had no clue how many watts/amps these things soaked up. I just wanted cold beer. Even now I struggle to keep up with Eggie and Fluffy.

    Ok, let me try again

    I have a Waeco 50L connected to a 102 amp Deltec high cycle in a NL powerpack. Usage is for camping on sites with no power for up to 4 days.

    Is this good ?

    I have a 105 AC Delco deep cycle that I keep in my trailer to power my Bundutop tent. How do I keep it charged.?

    I have a 43 amp portable battery box, how can I keep it charged to feed cell phones and camera batteries.?

    As posted in another thread: whilst at Afrikaburn for 5 days I used my two 70ah boat batteries in parallel to run my 50l Dometic/led lights/usb's/water pump and topped up(very quickly) with a 90w panel in the day - the fridge was set at -10 continuously(made ice every day) and the cut off set at HI (12.1v) - obviously higher ambient temps and cloud will screw with things but it worked very well. When on the road I used the 12v 120W power outlet.

    I have a 105Amp second battery in my LC in the back that is inside a NL battery box, it has a built in solenoid, I have two deep cycle batteries in my Commander, that I charge while driving from a separate Anderson connection on my tow bar, with its own solenoid.

    It can also charge from mains.. with my CTech

    Then I have a small 12v lumino battery set, to run my camping LED lights from, it charges with its own trickle charger through any lighter socket or 220v plug.

    Works lekker

    I would say, I have spent a lot of time and money gaining the knowledge that I have - AND I would prefer to talk to you. So, pop in and see me

    My previous panels was 2x 80W but found them to be a bit light in the pants when the weather doesn't play along. They got stolen when they broke into my house so the insurance kitted me out with a single 265W panel.
    The bigger panel, although bigger and heavier is awesome and seems to be more efficient, even in a bit (or a lot) of cloud cover, I don't need to track the sun so they just stay mounted on the roof and gives me all the power I need.

    I have a 40lt Engel, camp lights and of course the inverter sorts out camera batteries, phones, radios and other electronics.

    2x lead acid batteries, a 102Ah and a 105A/h. One connected to the panel and controller, the other to the solenoid dual battery system in the vehicle. The two batteries are changeable between the panel and vehicle charger so when less driving is involved I can alternate if needed.

    I was running 3x fridges, 2x 40lt Engel's and a 40lt Waeco, All camp lights for a party of 7 and with the only inverter in the camp had to do all the laptop, tablet, sat-phone, phones and camera batteries on a trip to Botswana a few years back and managed extremely well.

    Upside of this is that depending on type of trip, my system can be changed to suit.

    When calculating power and you try to save by getting the smallest system you think will work in watts? Well, triple it and you should be hassle free... I have had too many warm beers on trips I can call school fees...
    If Force is not the solution, not enough of it was applied....

    I would say from own experience double up on the battery capacity for the fridge.

    Oh, I have absolutely NO idea how much power the Vaping THING uses!!!

    I use a 1 000 w inverter for battery charging (cell phone, tablet, camera, laptop, re-chargeable lighting.

    Fridge runs 24x7 with reasonably frequent opening for beverages ..... set at between -2 and -5 deg C depending on ambient.

    Good for 3 days without ANY external power (Only 90W solar and alternator charging).
