5.3.7 Connection to the PV array
The INGECON SUN SMART TL family of inverters works with 3 independent PV arrays and each one has an ad-
vanced maximum power point tracking (MPPT) system to extract the maximum energy from each PV array.
This means that the unit has 3 independent MPPTs, each with the same nominal power, i.e. one third of the nominal
power of the whole unit.
The inverter is connected to the PV array by means of three sets of quick connect terminals specifically designed
for the purpose. This type of quick connect terminal requires the use of specific tools.
Each PV input (set of quick connectors) is suitable for connecting up to four STRINGS.
The three PV arrays must be independent. If the same PV array is connected to more than one of them, the unit
will not be connected to the grid.
Never forget that whenever they receive solar radiation, the panels generate voltage in their terminals.
The inverter can therefore have voltages of up to 550 volts inside even when not connected to the grid.
The inverter has a maximum system voltage of 550 Vdc. Check that the PV array configuration cannot supply this
voltage to the inverter even under the most adverse conditions, e.g. an ambient temperature of -10 °C.
In the case of damage due to the DC voltage exceeding 550 Vdc, Ingeteam Energy S.A. sill accept no liability for
such damage.
CAUTION:
Connect the positive pole of the solar panels to the terminals , and the negative
pole to the terminals marked -.
The inverter’s factory-fitted terminals support a maximum current of 20 amperes.
