SP PLUS Energy Centre Installation Notes
Introduction
SP PLUS Energy Centres are a kit of components which provide an easy to install, compliant,
On-Grid battery backup system with optional solar export. These notes provide specific
installation details on the various kits plus components to help make the most from using an
SP PLUS Energy Centre.
Energy Centre Kit Installation Overview
There are three major parts to each kit:-
SP PRO Interactive Inverter Charger
DC Switchboard (shown with Solar Regulator)
Battery Enclosure
The battery enclosure is floor mounting whilst the DC Switchboard and SP PRO are wall mount.
Connections between these three parts have been designed to allow flexibility in positioning of
all parts to suit many varied locations.
INSTALLATION LOCATION
The kit provides short cabling for minimum losses and as such the three parts need to be
installed within close proximity of each other. The battery enclosure is suitable for installation
outside however the DC Switchboard must be protected from the elements. An ideal location is
inside a garage. To minimise space required, install the battery enclosure on the outside wall
behind where the DC Switchboard and SP PRO are to be installed.

SP PLUS Energy Centre
Installation Notes
The distance to the main AC Switchboard must also be considered. An AC feed into and
another AC feed out of the SP PRO are required.
CHOOSING BACKUP CIRCUITS
Significant rewiring of the installations AC switchboard may be required to split out which
circuits are required to be battery backed. The easiest (in a typical domestic application) is to
make all circuits (excluding off peak loads like hot water) battery backed as long as this doesn’t
exceed the 63A feed through capacity of the SP PRO. This eliminates the need to split any
circuits out and provides a whole of house energy monitor via SP LINK however the customer
will need to manually choose which appliances to turn off during blackouts.
PLACEMENT OF SP PRO AND DC SWITCHBOARD
Wall Space Dimensions (mm) – 1250(w) x 1000(h).
The DC Switchboard has been designed to minimise cable length and cross-over of DC and AC
cabling. The DC Switchboard should be mounted at the same level and to the right of the
SP PRO. The minimum recommended width to mount both units is 1250mm. This allows for
250mm clearance either side of the SP PRO.
ADDITIONAL PARTS TO BE SUPPLIED
Some additional parts are required to be supplied by the installer.
AC Cabling – sized to suit maximum AC capacity.
32mm Conduit
25mm Conduit
Mounting hardware
Solar panels, cabling and isolators – if required
Note: DC Switchboard contains sufficient DIN rail space for mounting solar isolators.
Installing the Battery Enclosure
Dimensions (mm) – 765(w) x 755(h) x 525(d).
All sides and top can be removed from enclosure for access. In most cases, only one side is
required to be removed to fit and cable batteries.
Note: Assembly of Battery
Enclosure is covered by
separate assembly instructions

POWER PERFORMANCE PASSION
PLACEMENT
The battery enclosure (once fitted with batteries) is quite heavy and must be placed on a solid
surface - if to be placed on dirt, two concrete squares are suitable.
Adequate ventilation is required. Air is drawn in from below each side panel and vented out at
the top of the front side panel.
Note: Battery enclosure is only suitable for supplied sealed batteries.
Batteries are degraded by high temperature. Enclosure to be placed in coolest position and
MUST protected from direct sunlight.
Cable entry is provided on both sides and rear of the enclosure. Position the battery enclosure
to minimise cable length to DC switchboard via most appropriate cable entry point.
BATTERY POSITIONING
The battery enclosure will accept up to 8 batteries. Batteries can be slid into the enclosure
from either side.
Batteries should be placed according to the diagram below.
24 VDC 100Ah – (RA12-100A x 2)

48 VDC 100Ah – (RA12-100 x 4)
24 VDC 180Ah – (RA6-180 x 4)
48 VDC 180Ah – (RA6-180 x 8)
Repeat 24 VDC 180Ah layout on top and bottom shelf.
Note: To ensure battery bank cannot be accidentally short circuited, DO NOT fit any battery
links at this stage.

Installing the DC Switchboard
Dimensions (mm) – 410(w) x 750(h) x 75(d).
Mounting hole size max – M6
Weight – 17kg (including optional solar regulator)
Tools – 7mm Nut Driver
The DC Switchboard consists of two compartments both with LHS hinged doors for access. The
top compartment is for solar combining and switching. The lower half is for the battery fusing
and regulator mounting. The lower door, when assembled, can only be opened with the DC
fuse switch removed. All wiring is contained within the enclosure.
The DC Switchboard should be mounted allowing for the SP PRO to be mounted ~ 250mm to
the left.
CABLE ENTRY
The DC switchboard has the provision for cables to enter from the rear or top via knockouts. If
required, remove knockouts to suit installation.
PLACEMENT
The DC switchboard is to be mounted to a suitable solid surface with no particular temperature
requirements. Four key-holed mounting points are provided –

Installation Notes
Note: Diagram shows square rear cable entry knockouts.
Affix DC Switchboard using suitable fixing method for the wall construction.
SHUNT ASSEMBLY –LOWER COMPARTMENT (SOLAR OPTION ONLY)
Fit the shunt onto the two mounting studs, securing with the nuts and washers supplied.
REGULATOR ASSEMBLY –LOWER DOOR (SOLAR OPTION ONLY)
Prepare the regulator for mounting onto lower door by removing the rear cable entry knockout
(it does require a fair bit of persuasion) and removing both the lower and upper covers.
Remove lower two screws and gland plug on lower door.
Hang regulator onto two upper screws and then fit two lower screws into position. Tighten all
screws and refit top cover.
Installing the SP PRO
Install the SP PRO as per the SP PRO installation instructions.
The SP PRO should be mounted ~ 250mm to the left of the DC switchboard
