2 Description of LSPV inverter 010K to 020K
2.1 Description of the Device
The LSPV inverter is a three-phase solar inverter without a transformer, which has a particularly
high efficiency at any operating point and is suitable for the connection of a PV generator with a
power of 11kW up to 21.1 kW. Heat is dissipated only by convection, with an internal temperature
monitor protecting the device against exceeding the permissible ambient temperature. The LSPV
inverter is designed such that the device does not have to be opened for assembly and connection
work. All electrical connections are exclusively made with lockable connectors. The device features
an integrated DC isolating switch according to EN 60947-3, which considerably reduces the overall
installation work. The LSPV inverter provides the usual communication interfaces RS485, 230 V / 2
A AC relay (fault message), Ethernet, and USB. An illuminated graphical display shows the devel-
opment of the feed power and other operating data in a clearly arranged manner. An 8-key control
panel below the display provides excellent and comfortable control and navigation features. Based
on its design in protection class IP 65, the LSPV inverter can be installed at almost any outside
location.

WARNING
When using the solar inverter without transformer, do not ground the
positive or negative pole of the PV generator!
2.6 Reverse Current through Defective Modules
Reverse currents are fault currents that only occur in PV systems comprising parallel strings. Given
short circuits of individual modules or cells in a module, or a double ground fault, the open circuit
voltage of the string in question can drop (e.g. due to defective modules or parts of modules) so far
that the intact parallel strings will drive a reverse current through the defective string. This may
result in strong heating and therefore to a destruction of the string.
What is more, the reverse current may cause secondary damage.
To prevent such damage to PV systems, appropriate precautionary measures should be
taken. There are the following two cases:
1. The PV system is designed such that the reverse current which is flowing in case of a
failure and consists of the sum of the short-circuit currents of all intact strings in the
worst case does not result in the destruction of the damaged string and therefore in sec-
ondary damage either. The decisive factor here is the current carrying capacity of the
system components (connectors, lines) and the reverse current carrying capacity of the
modules. The appropriate data can be found in the manufacturer's data sheet. In this
case, it is not necessary to take any further measures.
2. The PV system is designed such that the reverse current flowing in case of a failure ex-
ceeds the destruction limit. In this case, each string must be separately protected by a
string fuse connected in series with the other string fuses. In case of a failure, this iso-
lates the string from the intact strings so that destruction is prevented.

2.7 Control Panel
The graphical user interface which is integrated on the front of the device and comprises 128 x 64
pixels can be used to display the development of interesting data, such as the feed power. The
parameters required are selected and entered on the 8-key control panel. The control panel is illu-
minated on pressing a key and turns dark automatically.

3.1 Unpacking the Device
The inverters are loaded at their head and packed upside down facilitate transport. You will there-
fore see the bottom side of the device (connectors) after having opened the package. Take the
device at the two holding grips that are visible on the side and remove it from the packaging. When
being unpacked, the device keeps the packaging grid locked in place on its housing. The packag-
ing grid can be used to deposit the device on the floor. This prevents the cover from being dam-
aged.
