Protection Features - Kaco blueplanet gridsave 92.0 TL3-S Manual

2 | Safety
– Operation in accordance with the appended EU Declaration of Conformity envisages up to 2 bidirectional feed-in in-
verters per battery.
– Approval from KACO new energy is required for a parallel DC circuit with more than 2 bidirectional feed-in inverters.
Any other or additional use is not considered proper or intended use and can lead to an annulment of the product guar-
antee. This includes:
– Mobile use
– Use in rooms where there is a risk of explosion
– Use of the device in direct sunlight, rain or a storm or other harsh environmental conditions
– Use in an outdoor area that does not meet the environmental conditions set down in the [See section 4.3} Page 13]
– Operation of devices with an inconsistent performance in DC parallel operation
– Operation of devices with an inconsistent firmware version in DC parallel operation
– Operation outside the specifications intended by the manufacturer
– Overvoltage of over 1,500V on the DC connection
– Modifying the device
– Off-grid operation

Protection features

The following monitoring and protection functions are integrated in the device:
– Overvoltage conductor / varistor to protect the power semiconductors from high-energy transients on the grid and
generator sides.
– Device temperature monitoring system
– EMC filter to protect the product from high-frequency grid interference
– Grid-side varistors grounded to earth to protect the product against burst and surge pulses
– Anti-islanding detection according to the current standards
NOTE
Information on other applications / system set ups (e.g. parallel operation / multiple bidirectional feed-in in-
verter) is provided project specific as an application note. For further details, please contact our KACO sales
team pv-projects.kaco.de@siemens.com.
NOTE
If the device is connected, the overvoltage conductors / varistors contained in the device have an impact on the
electrical system insulation resistance test as per HD 60364-6 / IEC 60364-6 Low-voltage installations- Part 6:
Verification.
IEC 60364-6 6.4.3.3 describes two options for this case. The first option is to disconnect devices with an over-
voltage conductor or, if this is not practicable, then the test voltage can be reduced to 250V.
