2. FOREWORD
Energy storage is the key solution to meeting the challenges of energy transition, using renewable energy and providing energy cost reductions for the following 4 main applications.
• Behind-the-Meter Energy Storage:
Reduce peak consumption and maximise PV energy self-consumption. SUNSYS PCS² (IM) can limit the impact
of increases in the electricity retail price by supplying the load to cut peak demand (peak shaving), maximising PV
energy self-consumption at building or community level. Any PV energy surplus is stored in the SUNSYS PCS² (IM)
battery system. This stored energy is used later to supply the load.
1
• PV plants:
Manage the intermittence of renewable energy production. SUNSYS PCS
2
(IM) ensures the production profile of an
intermittent renewable energy plant by limiting production to a predefined value, injecting energy to compensate for
solar variations, setting constant ramp-up or ramp-down.
2
10 EN
SUNSYS PCS2 IM UL Power Conversion System and Storage with Islanding Mode from 33 to 200 kVA - Ref.: IOMSUNPCXX07-EN 01
Page 11
• Grid support:
2
Meet the challenge of demand-response energy balance. When directly connected to the grid, SUNSYS PCS
(IM)
improves stability and management of grid operators thanks to voltage and frequency regulation, load shifting, peak
shaving and ancillary services for grid support.
3
• Microgrids:
Ensure energy availability and quality. The SUNSYS PCS² IM enables the microgrid to disconnect from the main grid
and be electrically autonomous thanks to local generation (PV, Wind, Diesel generators, etc.).

8.1 EXCEPTION FOR PCS2 IM 132 - 200 TL
The PCS2 IM 132 - 200 TL has two control panels:
- the upper one controls the upper three power modules (Module A, Module B, Module C).
- the lower one controls the lower three power modules (Module D, Module E, Module F).
So, the first start-up procedure must be applied to both control panels ('First start-up' chapter) and both have to be
used to monitor measurements, alarms, etc. ('Menu' chapter).
NOTE: in PCS2 132 TL, module A and D are not present.

8.2 CONVERTER STATE MACHINE
The SUNSYS PCS² IM implements the following state-machine concept:
INIT
SWITCHED-OFF ALARM
ON / OFF
SYSTEM READY
BLACK START
OFF-GRID MODE ON-GRID MODE
CHARGE / DISCHARGE
COMMAND
At system power-on by the auxiliary power supply, the SUNSYS PCS² IM automatically enters the SWITCHED-OFF
status: the Control Panel shows the message SWITCHED-OFF on the Status line on the display and the luminous
status bar is switched-off.
An ON command connects the DC source to the SUNSYS PCS² IM and it enters the SYSTEM READY status, after
checking the battery conditions are satisfactory. On the control panel, the battery icon is green (or yellow if a Battery
(1)
Warning is present
) and the number of powered-on power modules appears.
The system can then operate in two modes, following two different paths:
• OFF-GRID MODE, operating in islanding conditions, as a grid-former;
• ON-GRID MODE, grid-tied and operating as a grid-follower.
From the SYSTEM READY status, a BLACK START procedure can be performed, in order to energise an isolated
micro-grid by the battery system. After the black start procedure has completed, the SUNSYS PCS² IM enters
OFF-GRID MODE status, generating the proper voltage and frequency references for the micro-grid.
From the SYSTEM READY status, with a Charge/Discharge command, the SUNSYS PCS² IM synchronizes and
connects to the AC grid and enters ON-GRID MODE status. The SUNSYS PCS² IM follows P/Q references coming
from an external control device.
The direction of the power flow on the display shows the instantaneous charging/discharging operation. The
message INVERTER ON is displayed on the Status line on the display and the luminous status bar is switched-on
(1)
with a green or flashing yellow light (if at least one warning is present
).
Transitions from OFF-GRID MODE to ON-GRID MODE and vice versa are supported by the SUNSYS PCS² IM:
additional external devices and components shall be provided (e.g. synchronisation device, circuit breaker, measure-
ment system). Contact SOCOMEC for further information.
In the event of an alarm, the system enters ALARM status and switches-off to ensure conditions are safe. The lumi-
nous status bar is switched-on with a red light and an alarm message appears on the display panel.
1. A Warning does not cause the ESS to stop.

12.3 ADC CARD
This card manages four normally closed or normally open outputs and three digital inputs in configurable mode.
• Electrical data.
- Permitted rated current and voltage of normally open or normally closed contacts: 2 A 250 Vac depending on the
terminal used.
- Inputs are activated on loop closing.
• External ESD connection.
A remote emergency shutdown system (ESD) can be installed by means of the ADC card. Connect a normally closed
zero-potential contact to terminals IN1+ and IN1- of the ADC card.
Intervention of the ESD input switches off the SUNSYS PCS2 IM output.
2
To restore the SUNSYS PCS
IM to operation:
• Close the ESD contact on ‘IN 1’ on the ADC board.
• Send the Alarms Reset command.
The configuration and the designation of function for the card’s IN/OUT depends on the kind of batteries connected

15.3 RIDE THROUGH MODE & TIMINGS
The L/HVRT (Low and High Voltage Ride-Through) and L/HFRT (Low and High Frequency Ride-Through) define the
behavior of the system in response to low and high voltage and frequency excursions outside the normal range of
operation of the PCS.
The following pictures report an example of ride-through profiles that correspond to Rule 21 prescriptions.

15.4 RAMPS
Two types of ramp rate characteristics are defined:
- Soft-start ramp-up rate that defines the behavior of the device to ramp from zero to operating power after a trip
or at first system power-on.
- Normal ramp-up rate when the inverter is adjusting the output power.
Parameters can be set in the following menu:

15.5 ACTIVE/REACTIVE POWER CONTROL
Active and reactive power control represents one of the most important features of the Grid Support Utility Interactive
Inverters. Reactive power can be controlled using the Specified Power Factor (SPF) or the Volt-VAr Mode (Q(V)) functionalities, while active power can be performed using the Frequency-Watt (P(f)) or Volt-Watt (P(V)) functions.
1) SPF - Specified Power Factor: the inverter operates at a specified, non-unity power factor
2) Volt/VAr Mode (Q(V)): the inverter supplies or absorbs reactive power in response to fluctuations in grid voltage.
The figure below shows an example as reported in UL1741 Supplement SA standard.
Figure SA13.2
“Average” Volt-VAr curve for Q(V), Test 2
Page 83
3) Frequency-Watt (FW) function: the inverter may change its active power output with changes in grid frequency.
The figure below shows an example as reported in UL1741 Supplement SA standard.
Figure SA14.1
Freq-Watt characteristic #1 (maximum slope)
4) Volt-Watt (VW) function: the inverter may change its active power output with changes in grid voltage. The
figure below shows an example as reported in UL1741 Supplement SA.
