Grid Connection - Ingecon Sun 250 M220 Indoor Installation Manual

Ingeteam
The first power module contains the two abovementioned terminals for the auxiliary connection.
The auxiliary connection cable must be no greater than 2.5 mm
night-time power supply
The control of IngecOn Sun PowerMax inverters feeds from the PV array. Therefore, when the PV array has no
power, the inverter control turns off. In order to communicate with the unit at night, you have the option of ordering
the nIgHT POWeR SuPPLY KIT, which feeds the inverter control from the mains.
To supply the inverter from the grid, an auxiliary supply of 230 V at 50/60 Hz must be supplied.
The display will be operational, allowing users to navigate through the menus and access the inverter via communica-
tions, but the inverter settings may not be changed until the voltage of the PV array is within the MPPT range.
The number of power supplies must be the same as electronics power blocks.

5.4.13. grid connection

The cables for connecting the unit to the grid enter through the glands at the base of the cabinet. They must withstand
at least the phase voltage and 1000 V between a phase and ground.
If the inverter and the grid connection point are far enough apart to require the use of longer cables, an external
distribution box must be used close to the investor to make this connection.
The cable gauge must be suitable in each case for the power rating of the unit and site conditions.
Protections for the inverters to the electrical grid (all versions which include them) can withstand a short-circuit
current of up to 70 kA. nAc models do not have this protection. It must be assembled outside the unit and coordi-
nated with the installation.
Before any handling, check that there is no electrical hazard in the voltage input from the grid.
