2Installation Site Preparation
Before installing the Evolve home energy storage components, read all instructions and warnings in this manual.
CAUTION! All electrical installation work should be performed in accordance with local building and electrical
codes.
WARNING! Isolate the PCS from all energy sources prior to electrical installation by means of disconnects,
breakers or connectors. Failure to properly isolate either AC or DC sources may result in serious injury or
death. This system will generate an AC voltage at the off-grid terminals when DC source is applied.
CAUTION! The PCS cabinet weighs up to 65 kg, and the battery cabinet weighs up to 102 kg. Handle with care.
The wall to which the system is mounted must be load-bearing rated according to the local building code. Mechanical
lifts are recommended to position cabinets on the wall bracket.
NOTE: All interconnecting cables are limited in length, and designed specifically for adjacent cabinet mounting using
the manufactured wall brackets.
CAUTION! Do not install in direct sunlight. Battery performance is dependent upon operating ambient
temperature. Radiant heat absorbed in direct sunlight will greatly reduce the performance of the battery, and will
prematurely cause degradation of the display indicator panel on the PCS cabinet. The battery modules are rated for
full power operation between -10C to +40C.
2.1 Overview of PCS and Battery components
1. The cabinets can be installed in an indoor and outdoor non-corrosive environment (not marine environment).
2. The forced air cooling of the PCS cabinet is from bottom to top. Refer to figure 1 for recommended layout plan.
3. The PCS and Battery cabinets are rated NEMA 3R. This product requires an installation a minimum of 36” from
ground level if installed outdoors.
4. Wall mounting hardware not included. The load-bearing wall bracket is provisioned for M8 hardware. Levelling
brackets are provisioned for M5 hardware.
2.2 Installation Area Required to Wall Mount PCS and Battery:
The physical installation of the cabinets requires the layout planning and installation of the system components in the
available installation space. The recommended installation height is driven by the viewing angle of the display panel on
the PCS cabinet.
Figure 1: Installation clearances.

2.4 SLD - AC Coupled PV System with Back-up Power Operation
The single line diagram shown below is a representation of a typical installation configured for utility interactive and back-
up power operation, with AC coupled PV connected to a critical load panel. This drawing is a guideline only, and is not
a substitute for a code compliant installation. All components required for a code compliant installation are the
responsibility of the licensed installer, including any additional circuit protection requirements not shown here.
NOTES
1The backup power bus must be electrically isolated from the main electrical bus. Do not tap the neutral wires of the main
and backup buses. A separate line, neutral, and ground must be run to each of the load and grid ports of the battery
system. Refer to the installation manual for wiring details.
2Energy meter supports 1Ø and 3Ø configuration.
33Ø service shown. For 1Ø service, do not populate R,S ph components.
4The battery system must be earth bonded to the building ground to meet lightning protection requirements.
5The battery system load and grid ports are independently controlled circuits. Should the electrical code require
additional “line-of-sight” disconnects, a separate disconnect must be used for each of the grid and load ports. The
disconnects and/or circuit breakers must operate independently of each other, and not be ganged.
The PCS provides galvanic separation of AC and DC sources. Overcurrent protection devices, RCD Type A, are
sufficient for protection of both AC Grid and AC load ports.
6Total AC nameplate of PV not to exceed 5 kW. String inverter shown for simplicity. Multiple AC strings of micro-
inverters permitted. Any additional PV installed on the grid side of the battery system operates independently from the
battery system, and is only limited by the interconnection requirements of the utility service provider.


5.1 AC power connections
This battery system contains two independent AC power connection ports; one port dedicated for an electrical utility
connection, marked “AC Grid”, the other port dedicated for backup operation, marked “AC load”. This product’s primary
application is intended for utility interconnection, and must be connected to a utility electrical service supplying single
phase 230 Vac / 50 Hz. The backup operation of this product is a secondary application, and is intended to supply
emergency backup operation only. Under no circumstances should this product be used solely as an off-grid storage
system, nor should it be expected to perform whole home emergency backup power.
Note: The PCS provides galvanic separation between
AC and DC Sources. RCD protective devices of Type A
are sufficient for use as circuit over-current protection for
both AC Grid and AC Load ports.
CAUTION! To reduce the risk of fire, connect only to
a dedicated circuit provided with appropriate branch
circuit over-current protection in accordance with local
electrical codes.
WARNING! Improper connection of the wiring panel
may result in equipment damage and cause personal
injury. Disconnect all AC and DC Sources prior to
installation.
CAUTION! The AC grid and load ports are independent
circuits, controlled internally by an automatic bypass
and transfer switch. Each port must be connected to
electrically isolated panels. Tapping line or neutral
wires from the main electrical panel to the backup panel
will result in permanent damage to the product.
1. AC Grid Port: Open the spring clamp terminals
on the AC circuit board at the port marked “AC
Grid”.
2. Terminate the AC grid connection wires as
follows: “L_Grid” = Line, “N_Grid” = Neutral, and
“PE” = Ground
3. Close the spring clamp terminals, ensuring levers
are fully engaged.
4. AC Load Port: Open the spring clamp terminals
on the AC circuit board at the port marked “AC
Load”.
5. Terminate the wires at “L_AC load” (Line), “N_AC
load” (neutral), and “PE_AC load” (protective
earth).
6. Close the spring clamp terminals, ensuring levers
are fully engaged.
Figure 9: AC wiring.


5.2 Chassis Grounding
In this section, “Chassis Ground” is referred to as “ground” or “grounding” unless otherwise mentioned.
The AC and DC grounding are intended to provide a low impedance signal path at all frequencies.
DC Ground Wiring Installation: The PCS cabinet is shipped with ungrounded DC power terminals within the inverter.
However the default setting for DC grounding is set for DC negative to ground. This is to indicate that the DC negative
terminal of the inverter is grounded within the PCS system. The DC negative ground is completed once terminated in
the master battery cabinet, as the battery module DC bus is pre-wired with negative grounded battery modules. .
AC Ground Wiring Installation: The AC power grounding is achieved through the PE terminals of the AC grid connectors
on the AC Filter Board, as shown in section 6.1.
Note: The field ground wire rating applies to the AC circuit only. The DC source loop is internal to the battery
cabinet, and is rated accordingly.
Lightning Grounding: The inverter has built-in lightning protection. In order for the lightning protection to be effective, the
grounding for lightning currents must be provided via low impedance path from AC Filter Board to System Ground and
further to the building Ground/Earthing point.
6Energy meter installation
The energy management system’s solar self-consumption algorithm requires the connection of an energy meter at the
customer’s main electrical panel. The meter must be installed and configured according to the electrical service; either
single phase or three phase. The information covered in this guide is generic to the approved list of integrated energy
meters that are supported by the home storage system at the time of your purchase. Refer to the energy meter
manufacturer’s installation manual supplied with your system for full installation details and safety information.
6.1 Energy meter location
The meter supplied must be installed inside or
near the home’s electrical service panel. CT’s
supplied with the meter are provided with
standard 2.4 meter length wires. The meter
must be located such that the CT’s can be
terminated without extensions. If there is no
room inside the electrical panel, the meter
should be installed adjacent to the panel in an
enclosure rated for the environment in which it
is installed.
Energy meters supplied with the home storage
system are DIN rail mounted. Use existing DIN
rail space within the electrical panel, or add DIN
rail as required.
Figure 10: Energy meter location.

12
6.2 Electrical connections –voltage measurement / power supply
The energy meter provided with your system is line powered from
the electrical service. An in-line fuse, rated 1 Amp / 250 VAC, is
required on the voltage line, V1, input to the meter. For three
phase service, fuses are required on the V1, V2, and V3 input
terminals. The neutral connection does not require a fuse.
The voltage inputs can be connected anywhere on the customer
side of the main service disconnect breaker.
For three phase systems, phase rotation is automatically
configured by the meter.
6.3 CT (current transformer) connections
Note: Observe the current flow direction of the CT.
The direction of flow must be away from the utility
meter. For three phase systems, phase rotation is
automatically configured by the meter for your
convenience.
CAUTION! Handle CTs with care. Always terminate the
CTs at the meter inputs prior to clamping the core onto a
hot wire.
This system is supplied with split-core CTs for installation without interruption to the electrical service. The CTs must be
mounted on the primary electrical bus, between the main service breaker disconnect and the utility’s energy meter. This
is important to ensure all loads and generation are captured for optimum performance of the solar self consumption
control algorithms.
6.4 RS-485 communication connection
The battery system communicates with the meter using
the Modbus protocol over an RS-485 network. Shielded
twisted pair cable is required.
Note: Shield wire connected to earthing terminal at a
single point only.

9Start-up Sequence
CAUTION! Powering the Evolve home energy storage system requires a specific start-up procedure. Please
follow the steps below.
CAUTION! If the battery disconnect has been placed in the OFF position at any time during operation, wait
one minute before returning to the ON position. Rapid cycling (less than one minute) of the battery
disconnect can cause damage to the pre-charge circuit.
CAUTION! During the first start-up sequence after installation, the battery modules may require a battery
maintenance cycle to balance the SOC. This maintenance cycle requires a grid connection so that the PCS can be
commanded to charge the batteries. The PCS battery SOC alarm light will flash yellow if maintenance and/or other
battery faults are present. This procedure may take from a few minutes to a few hours, depending on the difference in
battery module SOC. Please refer to the PCS Service Manual for more information.
1. Remove the front cover from the battery cabinet adjacent to the
PCS cabinet.
2. Press the [Power] button (see above, label #8) on the master
battery module. The master battery module has communication
wired from the battery BMS port (label #4) to the PCS [BMS in]
port.
WARNING! When the batteries are turned ON, the battery voltage will
be present at the power panel assembly bus bar where the battery
modules are terminated.
3. This step may take up to one minute.
Verify that the indicators are as shown in “Normal Operation” as
shown below.
Battery Power Button Operation
WARNING! The master battery turns on the
slave battery modules in the battery rack via the
communication network. Do not use power
buttons to turn each module on individually. This
may cause damage to one or more batteries on
the DC bus.
Turn Batteries ON: Press and Release the
power button on the module designated as the
Master module (PCS connected com cable).
Turn Batteries OFF: Press and hold 5
seconds the power button of any module
designated as a Slave Module. If all modules do
not shut off, repeat individually for each module.

11.3 Service Button
The service button can be used to wake the LED display, and either place the system into or out of service mode, as
well as cycle through various operating modes. If the system has gone into service mode, the user can attempt to bring
the system back into normal operation using the service button.
Refer to section 12 –Troubleshooting if the service button does not perform the action requested.
12 Maintenance
The Evolve home energy storage system is a maintenance free product. Regularly scheduled inspection of the airflow
path for the active cooling fans on the bottom side of the PCS cabinet is all that is required. This inspection should occur
on an annual basis, or coincide with PV inspection.
If the fan ventilation holes are obstructed with dust / debris, a soft-bristled brush can be used to wipe them clean. For
heavy soiling use a soft, dry brush. Do not use any solvents, scouring, or corrosive materials to clean the unit. Never
remove or unplug connections or plugs during cleaning.
13 Troubleshooting
System faults are reported and logged in the monitoring system. All fault logs are also accessible remotely by your
installer.
IMPORTANT! Contact your system installer immediately if any of the following conditions are present on the
front display of the inverter panel.
