Quick Start Installation Guide
Getting Started
Step 1: Remove all modules from the cardboard boxes and associated packaging materials. Ensure that the brackets and included
accessories are kept.
Step 2: Inspect all parts for damage. Do not proceed with the installation if damage is observed. If in doubt please call the supplier.
Step 3: Ensure all accessories are present and correct. The included accessories should be as shown below.
any work on the system.
ŸDo not remove or dismantle the device modules. There are
no user serviceable parts within the products. Dismantling or
tampering with the modules will void the warranty.
ŸCheck all wiring connections before energising any part of
the system.
ŸRead the full user manual prior to commencing installation.
ŸIsolate all power supplied to the device prior to undertaking
ŸSuitable RCD protection must be installed according to local
wiring regulations
Installation safety precautions:
ŸThis system must only be installed by qualified personnel
familiar with applicable wiring regulations.
ŸOnly clean the modules with a clean cloth.

Drill holes 8mmØ,
depth approx. 70 mm
Step 2: Place the battery module against the wall and mark the 4 holes indicated below that are to be drilled. Using an 8mm Ø
masonry drill bit, drill 4 x holes approximately 70mm depth. Gently tap supplied nylon wall plugs in to the holes.
Step 3: Remove any debris. Secure the battery module to the wall using the supplied mounting screws and M6 washers. On the last
battery module of the stack, leave the two central screws unfitted and proceed to the next section for Inverter Installation
M6 Washers
Step 4: Repeat steps 1-3 for any additional batteries. Please note, for installs with more than 2 battery modules it will be necessary
to start a second battery stack to the right-hand side of the first.
Battery Installation - Note: The installation location must be in accordance with the User Manual
M5*12 Screws
Step 1: Attach the supplied wall mounting bracket to the battery module using the supplied M5x12mm screws.

Inverter Installation
Step 1: Place the wall mounting bracket included with the inverter against the wall and mark the two top holes. Using an 8mm Ø
masonry drill bit, drill 2 x holes approximately 70mm depth. Gently tap supplied nylon wall plugs in to the holes.
Step 2: Remove any debris. Secure the inverter bracket to the wall using the supplied screws (2 from battery installation + washers for
the bottom holes and 2 without washers for the top holes).
Step 3: Fit the inverter on to the bracket. Take care to ensure the rear tang correctly engages with the bracket.
Step 4: Loosely fit the 4xM5x12mm screws through the battery brackets in to the inverter. Before tightening the screws position the
inverter so that the removable inverter cover fits flush with the battery front panel(s). Do not fit the cover at this stage.

Battery Module Addressing
The battery module(s) communicate with the inverter module using an RJ45 cable connected from the inverter to the first battery
module (Battery top connector). Additional battery modules connect with the first battery module via RJ45 cables using the
communication ports on the side of the modules. Each battery module must have a unique address. This address is set via the DIP
switches shown below.
On single battery module applications the module address must be set to address 1. Additional modules switches should be set
according to the below table.

Connecting the Load Sensing Current Transformer
In order for the system to work correctly, a load sensing current transformer MUST be installed. Alternatively, an external Modbus
meter may be used. Meter installation is outside of the scope of this guide. Please refer to the full user manual if meter measurement
is needed.
The current transformer must be connected to the inverter using the supplied 4 way CT/Meter connector shown on page 1 of this
guide - The White wire (S1+) must be connected to pole 1 of the connector. the Black wire (S2-) must be wired to pole 2.
The current transformer must be installed as shown above. The arrow on the transformer must point towards the incoming utility
meter. The inverter must be able to see 100% of the load or it will not work correctly
Using the applicable wiring kit, depending on the number of installed battery modules, connect the modules together as shown below

Switching the System ON
When switching ON the system the user must follow the following procedure to prevent potential damage to the system
Step 1: On the side of each battery module there is a plastic cover, labelled DC Switch, lift the cover and switch ON each isolator
Step 2: Switch ON the external PV isolator (usually located in close proximity to the installation).
Step 3: Switch ON the external AC grid isolator or circuit breaker.
Step 4: On the inverter module, lift the hinged plastic cover on the cable box and switch ON Battery Switch and the PV Switch. If the
Backup load function is being used, switch the Load Switch ON also.
Step 5: Close the plastic cable box cover.
Step 6: On each battery module, on the front panel, there is a pushbutton, press the pushbutton until the lights illuminate. Repeat this step
for all battery modules.
Step 7: Fit the steel cover over the inverter cable box. Close and secure the hinged side covers on the battery module(s).
Step 8: The system is now powered. At this stage it is wise to switch on a load (for example a kettle) and check that the installation
behaves correctly.
Switching the system OFF
Step 1: Press the pushbutton on each battery module and wait for the lights to turn OFF.
Step 2: Remove the steel cover from over the inverter cable box.
Step 3: Open the hinged plastic cover on the inverter cable box.
Step 4: Switch OFF the Battery Switch and the PV Switch. If the Backup load function is being used, turn OFF the Load Switch too.
Step 5: Turn off the external AC grid isolator or circuit breaker.
Step 6:Turn OFF the external PV isolator (usually located in close proximity to the installation).
Step 7: The system is now isolated. If maintenance is to be undertaken, the DC switch on the side of each module will also need to be
switched OFF.

The energy generated by the solar panels will be used in
the following order: Feed the home loads; Charge the
battery and then, feed into the grid. When the sun is not
present, the load will be supported by the battery to
enhance self-consumption. If the power supply from the
batteries is not sufficient, the grid will support the load
demand.
