Protection Of The Connection To The Electricity Grid; Type Of Grid; Cabling Length; Photovoltaic Panels - Ingeteam INGECON SUN 160TL Manuel D'installation

Preparation for installing the unit
Reserve a solid wall to which to attach the unit. It must be possible to drill the wall and fit suitable wall anchors
and self-tapping screws to support the unit's weight.

5.4. Protection of the connection to the electricity grid

It is necessary to install protection elements in the connection between the inverter and the electricity grid.
Thermomagnetic circuit breaker
A thermomagnetic circuit breaker and/or fuse must be installed on the connection between the inverter and the
electricity grid.
The following table provides the necessary data for the selection of these devices by the installer.

When selecting the protection in an installation you must take into account that its breaking capacity is greater
than the short-circuit current of the grid connection point.
You must take into account when correctly selecting the protection that the ambient working temperature
influences the maximum current permitted by these protections as indicated by the manufacturer.
Integrated residual current device
These units inject differential current into the electricity grid. The current's amplitude depends mostly on the stray
capacity of the PV array to ground. The differential current in permanent status allowed by safety regulation IEC
62109 is 10 mARMS per kVA. A 160 kVA unit should be limited to a maximum of 1.6 Arms.

5.5. Type of grid

Below is the diagram of the supported network.

5.6. Cabling length

The inverter measures the voltage in its connection terminals. For this reason, the installer must use an AC cable
with a sufficiently low impedance so that increasing the voltage in the cable (between the distribution transformers
and the unit) does not cause the unit to be disconnected due to high voltage.

5.7. Photovoltaic panels

Standard IEC 62109 defines this inverter as a stand-alone inverter, and therefore the photovoltaic modules used
with it must be class A according to IEC 61730.
