4.3.4DIMENSIONING THE ALTERNATIVE ENERGY SOURCES

In a hybrid system, the alternative energy sources such as the solar generator, wind power and small hydropower should, in principle, be dimensioned in such a way as to be able to cover the average daily consumption.

4.4 Wiring diagrams

The diagrams shown in the appendix of this document are subsidiary. The applicable local installation regulations and standards must be adhered to.

The elements referred to with an uppercase letter denote the alternate current (AC) part. The elements referred to with a lowercase letter denote the direct current (DC) part.

4.5 Connecting the battery

Lead batteries are usually available in 2 V, 6 V or 12 V block types. In the majority of cases, in order to obtain an operating voltage that is correct for Xtender usage, several batteries must be connected in series or in parallel depending on the circumstances.

In multi-unit systems, all Xtenders from the same system must be connected according to the same battery bank.

The various cabling options are presented in figures 5a-5b (12 V), 5c-5e (24 V) and 6a to 6d (48 V) in appendix I of this manual.

4.5.1MINIMUM BATTERY CABLE CROSS-SECTION

XTH3000-12	XTH5000-24	XTH6000-48	XTH8000-48
90 mm2	90 mm2	70 mm2	90 mm2

The cable sections recommended above are valid for lengths less than 3 m. beyond this length it is strongly recommended to over-section the battery cables.

The battery cables must also be as short as possible.

It is always preferable to keep the cable at the negative pole of the battery as short as possible.

4.5.2CONNECTING THE BATTERY (XTENDER SIDE)

Insert the conduit glands supplied on the battery cable before tightening the cable clamp. Crimp the cable clamps and fasten the conduit gland on the device. Repeat this for the second battery cable. Fix the battery cables to the appropriate connections „+ Battery “and „- Battery “. The M8 screws must be very well tightened.

4.5.3DC INPUT PROTECTION

In order to avoid any further loss and protection redundancy, the Xtender does not have an internal fuse. A protection device (f) must be installed as close as possible to the battery and sized as per the table opposite:
