2 Overview
2.1 PCS for energy storage systems
The PCS is suitable for large-scale energy storage applications. A typical energy
storage system with this product generally consists of battery modules, PCS (this
product), energy management systems (EMS) and AC power distribution equipment
(Figure 2-1a /Figure 2-1b). It is used to convert DC power from battery modules to
AC with the same frequency and phase as the AC grid.
The PCS is UL 1741-SB certified to IEEE 1547-2018 standards, and offers Volt-Ride
Thru, Freq-Ride Thru, Ramp-Rate, PF, Volt-Var, Freq-Watt, Volt-Watt and other grid-
support functions.

When the storage system is in off-grid mode and has unbalanced single phase loads,
an external isolation transformer is necessary. If the power grid is lost, the contactor
on the grid side must be disconnected, and the PCS supplies power to the local load.

Environmental temperature monitoring
Battery temperature monitoring
LVRT (Low-voltage ride-through) and HVRT (High-voltage ride-through)
2.6 Circuit structure design
Basic schematic diagram of the PCS is shown below. The input of the batteries
passes through contactors and pre-charge circuit. The output of the PCS converts
the DC voltage to 3-phase AC voltage. An output filter is employed to remove the
high-frequency harmonics and reduce THD (Total Harmonic Distortion). Then the 3-
phase AC voltage is passed through two-stage relays and EMI wave filter to produce
high quality AC power.

3.2 Installation Precautions
Check that the product environmental specifications (protection degree,
operating temperature range, humidity and altitude, etc.) meet the
requirements of the specific project location;
Make sure that the power grid voltage is within allowed range: 422~528 VAC;
Ensure that the local electricity supply authority has granted permission to
connect to the grid;
Installation personnel must be qualified electricians or people who have
received professional training;
Wear and use PPE (personal protective equipment) during installation and
cable connection, such as safety shoes, safety gloves, safety helmet, etc.
INSTRUCTION:
The items in the accessory kit table above are for the standard
configuration.

Mechanical Installation
14 / 135
Sufficient space is provided to allow the PCS cooling system to operate
normally;
Install the PCS away from flammable or explosive substances;
Avoid installing the PCS in locations that exceed the temperature limits
specified in the PCS data sheet to limit undesirable power loss;
Do not install the PCS near any electromagnetic source which can
compromise the normal operation of electronic equipment;
The characteristics of salt mist are easily affected by factors such as
seawater, sea breeze, precipitation, relative humidity, terrain, and forest
range near the coast. Therefore, inverters should not be installed outdoors
in salt affected areas (within 500m from the coast).
3.3 Installation Requirements
3.3.1 Environment Requirements
The PCS is designed for large-scale energy storage application, it shall be installed
and used together with energy storage system. The PCS can be installed outdoor
and is able to withstand direct sunlight, rain or snow. However, to avoid power
derating due to high or sudden temperature fluctuations, it is recommended to install
the PCS under a roof or sunshade/rain-shed. Direct outdoor installation does not
impact warranty.
3.3.2 Installation Modes
The PCS shall be positioned on the mounting bracket horizontally and fastened with
appropriate screws firmly to avoid tilting and shifting.
3.3.3 Space Requirements
The following installation space clearance shall be met according to different
installation scenarios:
Install a single PCS.
The PCS shall be installed with at least 1 m (39.4 in.) of clearance to its left or
right side to leave room to remove fans from one side of the PCS if
maintenance is required. The other side (left or right) shall be installed at least
50 mm (1.97 in.) from the nearest object. The front and rear sides of the PCS
shall be installed at least 500 mm (19.7 in.) from the nearest object and shall
not be installed within the vicinity of any heat sources. See Figure 3-1 for more
information.
Figure 3-1 Install a single PCS on mounting bracket

Mechanical Installation
15 / 135
Install several PCSs by stacking on one mounting bracket (the bracket is not
included in the package and the diagram is for illustration purposes).
In addition to all the above distance requirements, a minimum distance of
50mm shall be kept between two adjacent PCSs to ensure good ventilation.
Figure 3-2 Stack installation on one mounting bracket
Position two sets of mounting brackets with stacked PCSs side by side.
In this scenario, a minimum distance of 1000 mm (39.37 in.) shall be reserved
on both sides of the mounting brackets so that the fan brackets can be pulled
out from their left side or the right side completely without any obstruction. In
the same way, a minimum distance of 50 mm shall be kept between two
adjacent stacked PCSs to ensure good ventilation.
Figure 3-3 Two sets of mounting brackets with stacked PCSs
NOTICE:
The Weight of one PCS is about 120kg (≈265 pounds).
Make sure mounting brackets can bear the total weight of all stacked
PCSs to avoid bracket damages and PCS falling off!
Consult the after-sale personnel for any special scenarios.

3.4.2 Lifting Instruction
Lift the PCS to the height that its bottom is aligned with the rail bracket so that it can
be placed onto the rail bracket smoothly. This operation can be achieved by the
following three lifting options shown below.
Manual lifting: at least three people are needed to properly lift and support
from the base surface (see figure 3-7);
Figure 3-7 Manual lifting from the base surface
Rope lifting: Operate as following steps.
(1) Screw two M10 eyebolts (non-standard) in two opposite sides of the
PCS.
Figure 3-8 Screw two M10 eyebolts

Mechanical Installation

(2) Use two ropes to lift the device with the aid of aforementioned eyebolts
and the two lifting holes on the front mounting bracket, see figure 3-9 for
details.
Figure 3-9 Rope lifting with eyebolts and lifting holes
NOTICE:
The length of ropes shall make sure the angle between two sling
ropes is less than 60 degree, thus avoiding to damage or bend the
enclosure edges.
Consult the after-sale personnel for any special scenarios.
Hoist the bottom of the PCS with forklift
(1) Find the center of gravity of the PCS as shown below.
