The Quattro can be connected to two independent AC sources for example shore-side power and a generator or two generators. The Quattro will automatically connect to the active source.

Two AC Outputs - The main output has no-break functionality. The Quattro takes over the supply to the connected loads in the event of a grid failure or when shore/generator power is disconnected. This happens so fast (less than 20 milliseconds) that computers and other electronic equipment will continue to operate without disruption. The second output is live only when AC is available on one of the inputs of the Quattro. Loads that should not discharge the battery like a water heater for example can be connected to this output.

Virtually unlimited power thanks to parallel operation - Up to 10 Quattro units can operate in parallel. Ten units 48/10000/140 for example will provide 90kW / 100kVA output power and 1400 Amps charging capacity.

Three phase capability - Three units can be configured for three-phase output. But that's not all: up to 10 sets of three units can be parallel connected to provide 270kW / 300kVA inverter power and more than 4000A charging capacity.

PowerControl - Dealing with limited generator shore-side or grid power - The Quattro is a very powerful battery charger. It will therefore draw a lot of current from the generator or shore side supply (16A per 5kVA Quattro at 230VAC). A current limit can be set on each AC input. The Quattro will then take account of other AC loads and use whatever is spare for charging thus preventing the generator or shore supply from being overloaded.

PowerAssist - Boosting shore or generator power - This feature takes the principle of PowerControl to a further dimension allowing the Quattro to supplement the capacity of the alternative source. Where peak power is so often required only for a limited period the Quattro will make sure that insufficient shore or generator power is immediately compensated for by power from the battery. When the load reduces the spare power is used to recharge the battery.

Solar energy: AC power available even during a grid failure - The Quattro can be used in off grid as well as grid connected PV and other alternative energy systems.

System configuring has never been easier - After installation the Quattro is ready to go. If settings have to be changed this can be done in a matter of minutes with a new DIP switch setting procedure. Even parallel and 3-phase operation can be programmed with DIP switches: no computer needed!.

Alternatively VE.Net can be used instead of the DIP switches and sophisticated software (VE.Bus Quick Configure and VE.Bus System Configurator) is available to configure several new advanced features.

Another fine Piece
As with Bowlbys' other works, this classic furthers the hypothesis of negative emotional influence on the continued development of humans as we integrate with our social environments. I liked it...in fact, liked all of Bowlbys' writings.

A Groundbreaking Classic on Young Child Development
Format: Paperback
This first volume of John Bowlby's trilogy on Attachment and Loss expands and builds upon an article he published in 1958 in the International Journal of Psycho-Analysis titled "The Nature of the Child's Tie to His Mother", which is perhaps a more telling title than that of the book itself. Attachment, as a technical term in behavioural biology, is first used in describing instinctive mother-following behaviours of young mammals and birds (first observed and reported in delightful accounts by the Austrian ethologist Konrad Lorenz in the 1930's). By comparing data collected during and after the Second World War by childcare workers and researchers in U.K. and North America, Bowlby found a striking common pattern of distressed behaviours among young children between the ages of one and three when separated from mother for an extended period: first in Protest, then Despair and finally Detachment - a psychopathological state when a child becomes socially uninitiated and withdrawn, even to his returning mother. Bowlby then postulates that physical proximity to a mother-figure is essential to a child's development of cognitive capacities, especially during a sensitive period around six months to two years after birth. Attachment behaviours, like those of young mammals and birds, are present in the human baby too. This has since led to a blossoming of research activities in development psychology and psychoanalysis, as well as neurophysiology recently, which supplies much fresh evidence about the young brain and its phenomenal maturing in the first two years. Attachment theory has since contributed significantly to understanding of our own selves, informed the age-old philosophical debate on nature or nurture, and brought our attention to fundamental issues in child-rearing such as sensitive periods of development, the difference between attachment (conducive to security) and dependence (symptomatic of insecurity), the distinction between anxiety from separation and fear of the unfamiliar, etc. This new edition is a timely reprint of a classic account of attachment theory as formulated by the originator. While primarily an academic work, with a few chapters deemed more for an academic jury (about Freud and instinctive behaviours, etc.), it is mostly very readable, and certainly captivating to those with access to young babies, of whose behaviours are given an enlightening perspective. This volume focuses on attachment, with subsequent volumes on its loss in temporary and permanent terms respectively.
