Hi there,

since I live in an 230V/50hz country, but much closer to the USA than Europe, it makes sense for me to source an inverter from the USA ...

would anybody know of any stores in the states that stock those true sine inverters?

any information welcome,

    The following is information and not a recommendation. Looks like you're in Santiago, Chile?

    OutBack Power manufacturers a broad range of TSW inverter/chargers for 230 VAC / 50 Hz markets. See: http://www.outbackpower.com/products/sinewave_inverter/international/

    Check this list for an OutBack distributor in Chile: http://www.outbackpower.com/contact/how_to_buy/distributors/

    US sources for OutBack's 230 VAC / 50 Hz inverter/chargers include Northern Arizona Wind and Sun (NAWS), this forum's host. See: http://store.solar-electric.com/oupoinoffgrb.html

    If you're looking for just a 230 VAC / 50 Hz inverter without a built-in charger, than a TSW model from Exeltech might work for you, and I believe that NAWS can get it for you. See: http://store.solar-electric.com/exsiwain.html

    mabe you could look up inverter suppliers in Australia and have them send you one ?/ If it is about 1000w sinewave they only weigh about 3kg or 7lbs so postage? freight would not be that high. Cost would be for inverter about au$700 about us$630..

    thx folks,

    your replies were most helpful, indeed!


    does anybody know if the exceltech XP1100 can be stacked (2 or 3 units in parallel)?

    ... I like the fact to have a system that could "grow" with our family's needs by adding units further down the road.


    thx again, indeed

    No stacking option available according to the manual (PDF).

    Is it the 12 VDC supply you are looking at or one of the higher voltage options?

    My 2 cents... Roughly 1,00-1,200 watts maximum at 12 volts (~120+ amps maximum, more if you allow 3 second 2x wattage peak current).

    If you are planning on a larger system, 24 volts (~2,400 watts max) or 48 volt (~4,800+ watts maximum) would be my suggestion.

    If you are going to use solar panels/chargers--typically the large MPPT type will charge 12-48 volt battery banks--but one charger can charge 4x larger battery banks (more solar panels) than a 12 volt system (60amps*15volts=9,000watts-max; 60amps*60volts=3,600watts-max solar panels).

    Only go with a fixed lower voltage (12 vdc, etc.) if you have a lot of specific 12 VDC loads that you need to support.

    Al,

    The Exeltech XP inverters can’t be stacked.

    However, you could wire several in parallel from the same battery bank. This would give you the option of running, say, just one inverter all the time to meet “constant” load requirements, and then fire up a second inverter only when required for occasional large loads on circuits separate from the first inverter's output.

    For example, I’ve been thinking about a system that would use, say, an 1100 W inverter (or one or two 600 W inverters) to efficiently run my computers and network, a/v system, fridge, CFL’s, chargers, and other small loads. Exeltech’s XP inverters include provisions for remote hardwire on/off switches.

    My “big” 2500 W inverter, which is not particularly efficient at small loads, would normally be off, but would be powered up for occasional large loads such as the washer, dryer (motor), vacuum cleaner, microwave, hair dryer, dehumidifier(s), and shop tools. My big inverter can be turned on/off via the Mate or via a remote hardwire switch.

    The goal here would to improve overall system efficiency by reducing the inefficient use of the big inverter with small “always on” loads. Higher efficiency means a smaller array and battery bank, and/or the ability to handle additional loads.

    I hear you clear on this "best of 2 worlds" topic ...


    To provide some additional information ... my bat.bank will be 24V ...

    and I managed to get our daily consumption down to around 2kwh x day (using all cf-lamps, netbooks, a good efficient fridge and the fact that our little one imploded the old tv-set also helped a good deal ;) )



    The only "big" load that I still have (and will keep) is the microwave (1300w based on a watt's up reading) and - to a lesser extent - the (clothes) washing machine (w/OUT heating element).


    How, in practical terms would a 2 inverter setup be done? How would you turn it on/off remotely?


    I figure the inverters will still be physically close to the batt's ... so how would my (uninvolved) wife fire up the 2nd unit in the "prohibited room"? :roll:


    thx for clearing this up for me, as i cant really visualize it.

    cheers,
