  Quattro 3kVA - 5kVA
  Two AC inputs with integrated transfer switch. The Quattro can be connected to two independent AC sources, for example Grid power and a generator, or two generators. The Quattro will automatically connect to the active source.
  All Quattro- and several Multi inverter/chargers now have two AC outputs. In addition to the standard no-break output, an auxiliary output is available which disconnects the connected load during battery operation. It is, for example, the perfect solution for preventing an electric water heater from discharging your battery.
  Just like the local utility grid, the inverter produces true sinewave AC electricity for your stand-alone or back-up power needs. Computers, TVs and pumps are just some of the examples of modern electronics that last longer and run better when powered with true sinewave electricity from an OutBack inverter. Starting up your well pump is worry-free because of our high surge power capability
  Battery Chargers and Auto Transformers
  One full rated output and one 4 Amp output.
  Charge voltage can be precisely adjusted to suit any battery system. The input for the charger is 230V at 50/60HZ.
  An external sensor allows to measure battery temperature and compensate charge voltage accordingly.
  The autotransformer: for step-up, step down and split phase balancing
  An autotransformer can be used for step-up, step-down and split phase output balancing purposes.
  While the step-up and step-down functions are fairly straightforward, split phase output balancing may require some more attention.

  An inverter is a device which changes DC power stored in a battery to standard 120/240 VAC electricity (also referred to as 110/220). Most solar power systems generate DC current which is stored in batteries. Nearly all lighting, appliances, motors, etc., are designed to use ac power, so it takes an inverter to make the switch from battery-stored DC to standard power (120 VAC, 60 Hz).
  In an inverter, direct current (DC) is switched back and forth to produce alternating current (AC). Then it is transformed, filtered, stepped, etc. to get it to an acceptable output waveform. The more processing, the cleaner and quieter the output, but the lower the efficiency of the conversion. The goal becomes to produce a waveform that is acceptable to all loads without sacrificing too much power into the conversion process.
  Inverters come in two basic output designs - sine wave and modified sine wave. Most 120VAC devices can use the modified sine wave, but there are some notable exceptions. Devices such as laser printers which use triacs and/or silicon controlled rectifiers are damaged when provided mod-sine wave power. Motors and power supplies usually run warmer and less efficiently on mod-sine wave power. Some things, like fans, amplifiers, and cheap fluorescent lights, give off an audible buzz on modified sine wave power. However, modified sine wave inverters make the conversion from DC to AC very efficiently. They are relatively inexpensive, and many of the electrical devices we use every day work fine on them.
  Sine wave inverters can virtually operate anything. Your utility company provides sine wave power, so a sine wave inverter is equal to or even better than utility supplied power. A sine wave inverter can "clean up" utility or generator supplied power because of its internal processing.
  Inverters are made with various internal features and many permit external equipment interface. Common internal features are internal battery chargers which can rapidly charge batteries when an AC source such as a generator or utility power is connected to the inverter's INPUT terminals. Auto-transfer switching is also a common internal feature which enables switching from either one AC source to another and/or from utility power to inverter power for designated loads. Battery temperature compensation, internal relays to control loads, automatic remote generator starting/stopping and many other programmable features are available.
  Most inverters produce 120VAC, but can be equipped with a step-up transformer to produce 120/240VAC. Some inverters can be series or parallel "stacked-interfaced" to produce 120/240VAC or to increase the available amperage.
  Synchronous inverters change DC power into AC power to be fed into the utility grid. A power system with this type of inverter uses the utility company as a storage battery. When the sun is shining, your electricity comes from the PV array, via the inverter. If the PV array is making more power than you are using, the excess is sold to the utility power company through a second electric meter. If you use more power than the PV array can supply, the utility makes up the difference. This type of system makes the most sense if you have utility power, because there are no batteries to maintain or replace, but it has a very long payback period and may not be cost-effective at today's electric rates. Using a multifunction inverter allows you to sell excess power to the utility, and also maintain a battery bank for standby power in the event of a utility power failure.
  Stand-alone inverters are available with three basic power output waveforms : square wave, modified square wave (sometimes called modified sine wave) and pure true sine wave. Synchronous Inverters and utility companies normally deliver a pure sine wave.
