    Battery boosting

    My little roost in the hills is totally off grid, and therefore needs plenty of the old currant bun to keep things going.
    This time of year, with low sun tracking, the solar panels just keep up with things.

    I understand that I can boost the battery levels by hooking up to a geny, but a mate reckons I am better off using jump leads from the truck, as it will charge much faster .

    What is the best way, aside from increasing solar panel capacity. ?

    Yep a mate who lives way back in the scrub just added a wind turbine to his solar system. Provides a trickle charge on all those crappy cloudy days and at night.

    Burnsco Marine has some cool stuff for 12-24 volt systems and inverters.

    Wind turbine is on the `to do ` list, but in the short term, I want to give the battery bank a good boost

    Depends on what alternator output the vehicle has,say its a 70 amp that equates to two hours running time at a high idle to match a generator putting out 1600 watts per hour.You would be better off with more solar panels or panel and another battery.Theres a shit load of variables involved in upgrading:the current system and budget for upgrades etc. Coon camp i run a 160 watt panel through MPPT controller running fridge and led lighting with top up from genny this time of year.I get by without genny during summer.I just replace ute battery and use that as camp battery when camp battery is getting lazy.

    Ute charging wont provide enough volts for good battery care,really need up to 14.4 volts.If you go for genny then 240 volt charger of about 20 amps should look after the batteries.

    Is your system 12V or 24V?

    Most generators have a 12V charging port but it is fairly low amperage. I'd be looking to add wind into the set up longer term.

    And do you know your battery storage capacity?

    you also need to know what your shed batteries are, wet lead acid, sealed lead acid (aka gel-cel), lithium, calcium etc. all require a different type of charging
