INGECON SUN STORAGE 1Play

3.3.4 In a grid connection system, how is the extra PV inverter controlled?

First of all it shall be checked that the PV inverter is an Ingeteam device, as shown in 3.1.3 only Ingeteam
inverters can be used to work in a common strategy and communication with the ISS 1Play.
In that case we will need an INGECON SUN EMS Board + wattmeter.
We will be able to control the full installation with the INGECON SUN EMS Board (installed into the Storage
1Play) and the wattmeter connected to the grid. The schema of the whole system will be as the one shown
below:
Figure 13: Grid connection system
The extra PV inverter will be considered as additional PV in the system and will supply only the needed power
demanded from the loads (Battery or consumption). This information will be sent to the PV inverter from the
EMS Board.
For further information it is highly recommended to read the "ISS 1Play Installations Technical Guide".

3.3.5 In a stand-alone system, how is the extra PV inverter controlled?

In a stand-alone system the extra PV power that will come from other Ingeteam's inverters, as shown in 3.1.3,
will be automatically controlled by the ISS 1Play itself.
The ISS 1Play controls its generated voltage using an algorithm which is based on the grid´s frequency
monitoring.
For further information it is highly recommended to read the "ISS 1Play Installations Technical Guide".
