Steca XtenderInstallation and Operating Instructions 723.932 Xtender V0.511 Seite 104.1 Choice of systemThe Xtender may be used in different system types, each of which must meet the standards andparticular requirements associated with the application or site of installation. Only anappropriately qualified installer can advise you effectively on the applicable standards with regardto the various systems and the country concerned.Examples of cabling are presented in appendix I of this manual, fig. 5 and following. Pleasecarefully read the notes associated with these examples in the tables on p. 29 and following.4.1.1 HYBRID TYPE STAND- ALONE SYSTEMSThe Xtender can be used as a primary supply system for grid-remote sites where a renewableenergy source (solar or hydraulic) is generally available and a generator is used as backup. Inthis case, batteries are generally recharged by a supply source such as solar modules, windpower or small hydropower systems. These supply sources must have their own voltage and/orcurrent regulation system and are connected directly to the battery. (Example, fig. 11)When the energy supply is insufficient, a generator is used as a back-up energy source. Thisallows the batteries to be recharged and direct supply to consumers via the Xtender transfer relay.When the input voltage source is a low power generator (lower than the power) thefactory settings (adapted to grid-connection) must be modified according to the“generator” column in the configuration table on p. 35.4.1.2 GRID- CONNECTED EMERGENCY SYSTEMSThe Xtender can be used as an emergency system, also known as an uninterruptible powersupply (UPS) – enabling a reliable supply to a site connected to an unreliable network. In theevent of an interruption to the energy supply from the public network, the Xtender, connected to abattery, substitutes the faulty source and enables a support supply to the users connecteddownstream. These will be supplied as long as the energy stored in the battery allows. Thebattery will quickly be recharged at the next reconnection to the public grid.Various application examples are described in figs. 8a – 8c in appendix I.The use of the Xtender as a UPS must be carried out by qualified personnel who havebeen checked by the responsible local authorities. The diagrams in the appendix aregiven for information and as a supplement. The applicable local standards andregulations must be adhered to.4.1.3 I NTEGRATED MOBILE SYSTEMSThese systems are meant to be temporarily connected to the grid and ensure the supply of themobile system when this is disconnected from the grid. The main applications are for boats,service vehicles and leisure vehicles. In these cases, two separate AC inputs are often required,one connected to the grid and the other connected to an on-board generator. Switching betweentwo sources must be carried out using an automatic or manual reversing switch, conforming tothe applicable local regulations. The Xtender has a single AC input.Various application examples are described in figs. 10a – 10b – 10c).4.1.4 MULTI - UNIT SYSTEMSWhatever system is selected, it is perfectly possible to realise systems composed of several unitsof the same type and the same power output. Up to three Xtenders in parallel or three extendersforming a three-phase grid or three times two with three Xtenders in parallel forming a three-phase / parallel grid, may be thus combined. |
