4 Cabling

The connection of the Xtender inverter / charger is an important installation step.

It may only be carried out by qualified personnel and in accordance with the applicable local regulations and standards. The installation must always comply with these standards.

Pay attention that connections are completely tightened and that each wire is connected at the right place.

4.1 Choice of system

The Xtender may be used in different system types, each of which must meet the standards and particular requirements associated with the application or site of installation. Only an appropriately qualified installer can advise you effectively on the applicable standards with regard to the various systems and the country concerned.

Examples of cabling are presented in appendix I of this manual, fig. 5 and following. Please carefully read the notes associated with these examples in the tables on p. 27 and following.

4.1.1HYBRID TYPE STAND-ALONE SYSTEMS

The Xtender can be used as a primary supply system for grid-remote sites where a renewable energy source (solar or hydraulic) is generally available and a generator is used as backup. In this case, batteries are generally recharged by a supply source such as solar modules, wind power or small hydropower systems. These supply sources must have their own voltage and/or current 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. This allows 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 Xtender power) the factory settings (adapted to grid-connection) must be modified according to the “generator” column in the configuration table on p. 34.

4.1.2GRID-CONNECTED EMERGENCY SYSTEMS

The Xtender can be used as an emergency system, also known as an uninterruptible power supply (UPS) – enabling a reliable supply to a site connected to an unreliable network. In the event of an interruption to the energy supply from the public network, the Xtender, connected to a battery, substitutes the faulty source and enables a support supply to the users connected downstream. These will be supplied as long as the energy stored in the battery allows. The battery 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 have been checked by the responsible local authorities. The diagrams in the appendix are given for information and as a supplement. The applicable local standards and regulations must be adhered to.

4.1.3INTEGRATED MOBILE SYSTEMS

These systems are meant to be temporarily connected to the grid and ensure the supply of the mobile system when this is disconnected from the grid. The main applications are for boats, service
