    Frankly after the power outages last year everyone geared up with a very expensive gensets which have now been sitting idle ever since.

    If I was you I'd advertise to take someone's off their hands - make sure it's a diesel as the petrol ones are not geared for constant use but only as a stopgap measure and most say must be turned off after 2/3 hours usage for 1 hour or somesuch.

    On the same front, the Chinese have gotten into solar panel production in a big way and knocked the stuffing out of the stupid prices that were being asked - so much so that the US and Europe are contemplating some silly protectionist taxing on them.

    This could mean a short term massive drop in the prices, but whether that makes its way through to us in Bali is another question.

    That would be the way to go for a long term solution to any energy issues here in the tropics.

    Interesting that my question turns into a discussion of solar power but, is that practical?
    I understand that solar panels only generate 12VDC and need a battery bank for storage then an inverter/transformer to connect to the villa before it can be useful....I don't have that much space.....unless I cover the pool!
    Others say the intermittent power supply last year will not be repeated...let's hope so.....or please, give me the # to get the cold beer!

    My query was based on an article in the Bali Daily last week which indicated that most of Bali PLN power came from hydro-plants in Java and transmitted by submarine cables to Gillimanuk. There was additional info that a diesel generation plant was contemplated but locals complained about the possible noise..... so that project is on hold. Also...hi-towers with wires crossing the straits are on the drawing board...how's that progressing?

    Just like on a Yacht - the diesel motor generates 12V dc which then goes to deep cycle batteries then through an converter to AC and then into your fridge where the Bintangs are waiting, the Tequila bubbling and the limes chatting amongst themselves. You would put it on your roof not the pool I think? It's still an expensive one-off solution and probably not economic yet here in Bali but prices are dropping so soon maybe. We sure have the sun for it.

    Well markit that isn't how the genset worked on my yacht or any others that I know of.
    My 8KW diesel genset produced 120/240 VAC and the speed of the engine controlled the Hertz, just like the ones from Ace hardware...the only difference is boat gensets are generally water cooled where-as house units are generally air cooled. A battery charger converts this AC to 12/24VDC to re-charge the start battery.
    Smaller gensets like the Honda are inverter rigged but only produce about 1-3 kW
    A frig on a boat is generally 12VDC but uses an internal switch to VAC when available.

    I do like your idea of chatting limes for the vodka and bubbling tequila though, but my frig is currently quite full of boxes of Hatten's finest puteh and merah wines. They really, really need to be chilled to be drinkable.

    Sorry my bad, said yacht meant barge. Canal barge to be exact, chug, chug, chug.

    Oohh! I understand...you meant the main engine alternator which works the way you explained. Then there would be an Inverter to change 12VDC to VAC from the large battery bank...I also had one of those which I used at night as it is silent, then, if not running the main engines at anchor, I'd fire up the genset in the morning to recharge the batteries and provide VAC for the electric cooker and coffee pot.

    Bit off topic but did you have that as a secondary system on your yacht? I've heard of that too for those doing long time cruising and wanting to stay in place for weeks or months.

    You're right Markit...I do all my boating during Summer in the PNW between Washington State and Southern Alaska but principally in the coves and ravines of British Columbia in Canada.
    We could be anchored in a shallow cove for up to a week with nothing but wild life and forests and waterfalls to witness. The genset is needed to keep the deep freezer working so the salmon and crabs we catch can be preserved, the steaks for the BBQ are still fresh and the bubbly is chilled...this isn't camping!!!
    It also re-charges the batteries so that, in the evening, we shut down the noisy genset and the Inverter (powered from the battery bank) kicks in to provide that power.

    I suppose a similar sysytem is used in remote areas for housing. In my villa I think a small quiet Honda might suffice as an emergency back-up assuming power outage is spasmodic.
