Ups Installations - Ingeteam INGECON SUN STORAGE 1Play TL M Technical Manual For Installations

2.2 UPS 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 TL M inverter internally disconnects the installation from the grid and
provides the necessary power for the critical loads from the batteries. For TT installations, the inverter
connects the neutral of the critical loads to ground through its internal grounding relay.
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 10ms, which means that a power cut is imperceptible for
most loads.
Installation components:
•
Photovoltaic panels (optional).
•
Battery bank.
•
ISS 1Play TL M inverter.
•
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 TL M. 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 TL M. In
installations where the power of the loads is lower than that of the ISS 1Play TL M, the non-critical
load installation is optional. In installations where the power of the loads is higher than that of the ISS
1Play TL M, non-critical loads must be disconnected until the remaining loads are below the power of
the ISS 1Play TL M.
This inverter is equipped with the AC Bypass functionality, it is only available when the PV panels or the
battery bank supply the inverter. With this functionality if the grid is available, in the event of an alarm or
firmware update, the loads will be powered from the grid (AC Bypass closed). In case of manual stop, through
the button of the inverter, the AC Bypass will be opened. The inverter must be supplied from the DC side,
battery or PV.
Although the INGECON SUN STORAGE 1Play TL M 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.
