Inverter; How Should Be Configured The Nominal Voltage And Frequency Values - Ingeteam INGECON SUN STORAGE 1Play Technical Manual

5.2 Inverter

5.2.1 How should be configured the nominal voltage and frequency values?

AC Voltage and Frequency parameters have different purpose for on-grid or off-grid situations:
- In grid-connection systems: Those values must be the nominal values of the utility grid.
- In stand-alone systems: These values will be used to fed the AC Loads Port.
5.3 Grid/Genset
5.3.1 When is the Manual connection function used?
It is used to manually connect the inverter to the grid/genset. In the case of Stand-alone operation mode, it
could be useful when the user/installer wants to connect the inverter to the genset in order to charge the
batteries and supply the loads from it, even if the SOC hasn't reached the SOCmin (activation of the genset)
This function is located at Main menu > Configuration > Grid/Genset > Manual connection
5.4 Digital I/O
5.4.1 In the ISS 1Play, how are digital outputs used?
The ISS 1Play is provided with two voltage-free digital outputs. Each output is independent and managed by a
relay that can operate until 230Vac and 6A. These digital outputs have been included for several functions in
the ISS 1Play depending on their configuration. All the functions are included in "Installation and Operation
Manual".
The following figures include the behavior of the digital output depending on its state. It has been included a
normally open relay which is handled by the digital output, the performance of a normally closed relay will be
the opposite. The source used to provide the voltage and the current shall comply with ISS 1Play digital
output and with the external contactor requirements.
5.4.2 In the ISS 1Play, how are digital inputs used?
The ISS 1Play includes digital inputs to be used in different purposes, all the functions related to this input are
defined in "Installation and Operation Manual". The inputs are isolated and can operate with one dry contact
or a DC voltage from 0 to 24V.
The following images include the state of the digital input depending on an external contactor. It includes a
normally open relay and a switch to manage it, using a normally closed relay will take the opposite behavior.
