2 Types of installations
2.1 Self-consumption installations
A self-consumption installation is a system connected to the grid that seeks to minimize grid consumption and
to increase self-supply. To do so, it is fitted with photovoltaic generation and storage components. The
inverter has the possibility of operating just from the PV array and of adding the storage system at a later
date.
An additional Battery-Backup function can be activated in this type of installation, to activate the Battery-
Backup function it is necessary to have a battery bank or PV panels. Although, it is possible to activate the
backup function from PV (without battery); however, it is recommended the use of batteries to ensure the
supply of the critical loads. The INGECON SUN photovoltaic inverter is disconnected to the grid and it doesn’t
supply energy. The non-critical loads are not fed. For TT installations, the inverter connects the neutral of the
critical loads to ground through its internal grounding relay.
Installation components:
•Photovoltaic panels.
•Battery bank. Recommended for Battery-Backup.
•ISS 1Play TL M inverter.
•External wattmeter. Check the “List of approved Power Meter for ISS 1Play TL M”, available in the
Ingeteam webpage. (In case of use the internal wattmeter of the inverter, consult the “Installation and
Operation Manual” of ISS 1Play TL M, available in the Ingeteam webpage).
•INGECON SUN photovoltaic inverter (optional). To increase the photovoltaic power of the installation.
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 and the Battery-Backup function
activated, 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.

Figure 2: Self-consumption installation
Operating mode
The EMS of the ISS 1Play TL M manages the energy flows in the installation in line with the following
principles:
•If the grid is available, it operates in the same manner as a self-consumption installation:
oPhotovoltaic energy is used as a priority to supply loads and to charge the battery. Grid
supply of photovoltaic surplus is user configurable.
oIf the photovoltaic energy is insufficient to power loads, the battery provides the remainder.
oIf the sum of photovoltaic and battery energy is not enough to power the loads, the grid
provides the remaining power.
oOnce the SOC Min value set by the user has been reached, the energy supply from the
battery is not restarted until SOC Recovery is reached. This prevents excessive battery
cycling, extending their working life.
oThe schedule for battery charging from the grid is user configurable.
•If the grid is not operational and the Battery-Backup function is activated, only the ISS 1Play TL M
powers the critical loads until the battery is completely flat (SOC Descx). At this point, the critical loads
are no longer powered until the grid is available once again of until SOC Recx is reached using
photovoltaic energy of the ISS 1Play TL M. The INGECON SUN photovoltaic inverter is disconnected
to the grid and it doesn’t supply energy.

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.

Figure 3: UPS installation
Operating mode
The ISS 1Play TL M manages the energy flows in the installation in line with the following principles:
•When the grid is operational, the priority is to keep the batteries fully charged SOC Grid so that they
can be used as back-up when required. Loads and the battery, if it must be charged, are supplied with
photovoltaic energy as a priority.
oWhen photovoltaic energy is used to supply the loads or charge the batteries, there is a
reduction in grid consumption.
oIn the event of surplus photovoltaic energy, the user can decide whether to supply the grid or
limit photovoltaic production through the configuration.
•If the grid is out of service, the ISS 1Play TL M disconnects the installation from the grid and provides
energy to the loads from the batteries until they get discharged SOC Descx. At this point, the loads
are no longer powered until the grid is available once again of until SOC Recx is reached using
photovoltaic energy of the ISS 1Play TL M.

2.3 Stand-alone installations
A stand-alone installation is a system disconnected from the public grid that provides AC. energy to a set of
loads.
Installation components:
•Photovoltaic panels.
•Battery bank.
•ISS 1Play TL M inverter.
•Support diesel genset (optional) 6500W max, that is connected in the case of an energy deficit.
•INGECON SUN photovoltaic inverter (optional). To increase the photovoltaic power of the installation.
It is necessary to set the Country/Regulation as SUN STORAGE.
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 diesel genset is available, in the event of an
alarm or firmware update, the loads will be powered from the diesel genset (AC bypass closed). In case of
manual stop of the inverter, the AC bypass will be opened.
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 to avoid
transient voltage drops (2-3 seconds) during their connection.
Technical notes:
•The power of the loads must under no circumstances be above the rated power of the inverter.
•If the battery is lead-acid, the capacity must be at least C10 ≥ 5x PPV/Vbatt to ensure stable operation
of the system. For lithium batteries, consult the capacity limitation with the battery manufacturer.
•The power of additional INGECON SUN photovoltaic inverters must under no circumstances be
above the double of the rated power of the ISS 1Play TL M.

The ISS 1Play TL M manages the energy flows in the installation in line with the following principles:
•Photovoltaic energy is used as a priority to supply loads and to charge the battery.
•If the photovoltaic energy is insufficient to power loads, the battery provides the remainder.
•If the state of charge (SOC) of the battery reaches a minimum value established by the user SOC On,
the diesel genset will be connected. It will remain connected until the battery reaches the SOC Off.
•If the diesel genset is not operational, the ISS 1Play TL M powers loads until the battery is completely
flat (SOC Descx). At this point, the loads are no longer powered until SOC Recx is reached using
photovoltaic energy of the ISS 1Play TL M.
