3.2 UPS (back-up) installations

A UPS (Uninterruptible Power Supply) installation is a system connected to the public grid that is used as
back up in the event of a power cut. In this case, the installation acts in a similar manner to an uninterrupted
power supply system.
This type of installation is typical in grids that present frequent interruptions or in the case of critical loads for
which the power supply cannot be interrupted.
In the case of a power cut, the ISS 1Play inverter internally disconnects the installation from the grid and
provides the necessary power for the loads from the batteries. To do so, the batteries remain charged while
grid electricity is available and the photovoltaic energy is used to supply the loads, reducing energy
consumption from the grid. Grid supply of photovoltaic surplus is user configurable.
The response time of the system to a power cut is 12ms, which means that a power cut is imperceptible for
most loads.
Installation components:
Photovoltaic panels (optional).
Battery bank.
ISS 1Play inverter.
Contactor for connection of neutral to ground for TT installations. In the event of a power cut, the ISS
1Play disconnects from the grid and activates this contactor to reference the neutral of the installation
to ground. In case of TN installations, this contactor is not necessary.
Manual bypass switch (optional). In the event of an ISS 1Play fault or maintenance, this allows for the
loads to be powered from the grid. It is formed by 2 independent interlocking manual switches that
connect alternately.
Non-critical loads. These are loads that, in the event of a power cut, do not need an uninterrupted
power supply. These loads are connected upstream from the ISS 1Play. Hence, in the event of a
power cut, they are disconnected to increase the number of hours of autonomy. Even with
photovoltaic surplus and charged batteries, these loads will not be powered by the ISS 1Play. In
installations where the power of the loads is lower than that of the ISS 1Play, the non-critical load
installation is optional. In installations where the power of the loads is higher than that of the ISS
1Play, non-critical loads must be disconnected until the remaining loads are below the power of the
ISS 1Play.
To monitor this installation, an additional kit for Ethernet or Wi-Fi communications is required.
Although the INGECON SUN STORAGE 1Play provides an extra current during load connection transients
such as motors, INGETEAM recommends the use of frequency drives with this type of load for the installation
to work properly in UPS mode.
Technical notes:
The battery capacity must be at least C10
