4 Installation Instructions Powador 01xi
- Operation of the devices with defective protective
equipment
- Manipulation of the device or makeshift repairs
- Influence of foreign objects or Act of God
(lightning, overvoltage, tempest, fire)
- Inadequate ventilation of the device
- Non-adherence to the relevant safety instructions
(VDE (Association of German Engineers), a.o.
- Transport damage
All guarantee claims shall be handled at the premises of
KACO Gerätetechnik GmbH. To this end, return
transport shall be effected, as far as possible, in the
original or equivalent packaging. The costs for these
services cannot be borne by KACO Gerätetechnik
GmbH.
Guarantee claims shall only be compensated by KACO
if the damaged device is returned to KACO together
with a copy of the invoice issued to the consumer by the
specialist dealer. The type label on the device must be
fully legible. In the event of noncompliance KACO
reserves the right to deny guarantee services.
The warranty period for rework or replacement
shipments shall be six months after shipment. However,
it shall continue at least until expiration of the original
warranty period granted for the shipped object.
3.2 Service
High quality and longevity of our inverters always have
been of central importance for us - already at the time
of product development. Our more than 60 years of
experience in the field of current inverters are backing
up this philosophy.
Despite all these quality-assuring measures, however,
failures may occur in very rare cases. KACO
GERÄTETECHNIK GmbH will offer a maximum of
assistance if one of these cases should arise. KACO
GERÄTETECHNIK GmbH will take every effort to
remedy any defects fast and without any unnecessary
bureaucracy. Please contact our service department
directly – and you will be aided and supported very
quickly.
3.3
Intended use (normal use)
Powador inverters are built according to state-of-the-art
and approved safety requirements. However, improper
use may cause lethal hazards for operators or third
parties and/or damage of instruments/devices or other
property. The device is intended to convert the direct
voltage generated in the photovoltaic (PV) modules into
alternating voltage (AC) and feed this voltage into the
grid.
The inverter must only be operated in connection with a
fixed/stationary connection to the public grid. Inverters
are not intended for mobile use.
Any use other than the specified intended use is not
deemed intended or normal use, and the
manufacturer/supplier shall not be liable for any
damage caused by such unintended use. Damage
caused by unintended use is at the sole risk of the
operator.
The term ”intended use“ shall also include the
adherence to the operating and installation instructions.
Some of the documents which are needed for these
applications and acceptance are attached to these
installation instructions.
4. Device
description
The electrically isolated Powador xi-series devices are
currently available for three different power classes.
The appropriate inverter type is selected in accordance
with the selected and mounted photovoltaic modules.
The max. power values are indicated in the data sheet
(Section 9).
The inverter designation is shown on the front side
above the display and on the type label.
4.1
Dimensioning of the PV generator
The selection of the PV generator is of crucial
importance when dimensioning a PV installation. It must
be observed by all means that the solar generator is the
right match for the inverter. Please observe the data
given in the Technical Data Sheet (Section 9) for
dimensioning the solar generator.
Dimensioning of the PV generator:
The number of PV modules connected in series must
be selected in such a way that the output voltage of the
PV generator is maintained within the admissible input
voltage range of the inverter – even in the event of
extreme external temperatures. In Central Europe,
module temperatures between –10°C and +70°C
should be assumed. Depending on the type of module
assembly and geographical conditions, +60°C or +70°C
should be used for calculating the voltage. The
temperature coefficient of the solar modules should be
observed. The following criteria must be met for
calculating the voltage of the PV generator:
Uo (-10°C) < max. input voltage (500VDC)
Even at very low external temperatures (-10°C), the no-
load voltage of the connected string must remain within
the admissible input voltage range. For example, if the
temperature falls from 25°C to –10 °C, the no-load
voltage of 12-V modules will increase by approx. 2.8 V
per module (5.6 V for 24V modules). The no-load
voltage of the entire string must be less than 500 volts.
