Type Of Grid - Ingeteam INGECON SUN 3TL Installation And Operation Manual

Preparation for installing the unit
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 amplitude of the current 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:
Maximum current
External residual current device
If the applicable regulations of the country require a residual current device between the inverter and the electricity
grid, this must be greater than:
Maximum current
The residual current protection integrated in the unit does not detect residual currents produced upstream of the
inverter. If a residual current device is installed upstream of the inverter or inverters, it must:
• Have an assigned trip residual current of at least the sum of the residual currents of the units connected
downstream.
• Be of type B.
Any residual current device connected upstream of three units must be type B and have an assigned residual
current of at least:
Minimum residual current

5.5. Type of grid

These inverters can be connected to single-phase or two-phase grids that have the characteristics below. They are
not compatible with Split-phase grids.
Single-phase grid 220/240 Vac (L-N-PE)
