INSPECT:
Ensure that these cables are plugged in and clicked into place securely to avoid communication issues
between the batteries and the inverter.
All M48-Select connections are now in place.
3.6 Wiring SP PRO
This section includes the power and communications wiring for the SP PRO.
The power & communications wiring must be completed for the SP PRO. All internal DC wiring for the M48-Select enclosure
is prewired upon delivery.
Refer to the schematics for the M48-Select found in Appendix A, Appendix B & Appendix C for help with the wiring of the
system.
All inverter power and communications cables must pass through the inverter gland plate holes.
Note: Passthrough from AC Source to AC Loads via SP PRO
After the completion of all M48-Select installation wiring, the SP PRO allows for AC Bypass from the AC source to AC loads
via the SP PRO, even when the SP PRO is not powered on by the batteries. This passthrough will display on the SP PRO’s LED
display, for example:
Rev.1.12 25 | P a g eFor off grid: when the SP PRO isolators are turned off, no power will be supplied to the loads from the batteries, unless a
generator is available.
3.6.1 Inverter power wiring
Connect the power cables into the inverter before the communication cables.
The inverter’s power connection terminals are labelled as follows:
3.6.1.1 Inverter DC wiring
EVO Power have provided 1m lengths of 70mm² cable for the B+
positive and B- negative battery terminals in the SP PRO, which
protrudes from the top of the M48-Select enclosure. The B+ cable has
red heat shrink on the end, while the B- cable does not.
Push this through the SP PRO Glands and cut back the DC cable until
it is at an appropriate length between the SP PRO & M48-Select
enclosure.
Strip back the 70mm² cable insulation by 28mm, and connect the
cables to their respective B+ & B- terminals in the SP PRO.
3.6.1.2 Inverter AC wiring
DANGER!
The SP PRO is overvoltage category III meaning that it must be a fixed installation connected either downstream
of (customer’s side) or directly to the main switchboard.
WARNING: Copper wiring must be used throughout.
The SP PRO does not contain internal circuit breakers of fuses. The AC wiring must be fitted with appropriate fusing or circuit
breakers.
The AC cabling should be sized according to maximum demand through (consumed by the AC Load) and simultaneously
consumed by the SP PRO (consumed by the charging of batteries). The SP PRO is fitted with terminals which are suitable for
accepting up to 35 mm² cables. The SP PRO is rated to 63 A current capacity and must be protected externally with circuit
protection device(s) of no greater than this.
Rev.1.12 26 | P a g eAC wiring should be fed up through the appropriate gland and terminated to the SP PRO. Connect the AC load wiring to
the SP PRO: earth, neutral and active stripped back according to the table below and connected to the AC load
terminals.
Connect the AC source wiring to the SP PRO: earth, neutral and active stripped back according to the table below and
connected to the AC Source terminals.
DANGER!
Multiple Hazardous Energy Sources AC wiring is fed from multiple sources. Care must be taken to ensure that
under no circumstances could a user access or touch wiring, even after opening all circuit breakers
DANGER!
It is critical that all protective earth connections made within the SP PRO use the protective earth
terminal. This is the earth terminal that is on the right hand side of the AC terminals and marked with
a earth symbol enclosed in a circle.
The inverter shall be earthed to the installation’s Earth system. A minimum copper earthing conductor no less than the size in
the table below, shall be used. See the local regulations for further information on earthing conductor size.
Earth the inverter by connecting earth wiring from the switchboard to the inverter Earth terminal. The SP PRO is suitable for
Multiple Earth Neutral systems.
Note: This table is given as a reference only. Please ensure all wiring complies with relevant safety standards.
3.6.1.3 Residual Current Device (RCD) Type Recommendation:
The SP PRO produces a low distortion sine wave output via 50/60 Hz isolation transformer. This topology ensures that the
output is sinusoidal and that there is no DC component associated with the SP PRO AC supply, whether that be feeding a
domestic load or exporting solar to the grid. Standard Type AC RCDs are suitable for use with an SP PRO. Other types of
RCDs may also be used.
3.6.1.4 AC Wiring Preparation
The intended application and use of the SP PRO must be well understood to allow the SP PRO to be appropriately
connected to the installation. How the SP PRO is wired into the switchboard is dependent on whether all the installation’s
loads or only essential loads are to be supplied by the SP PRO for tariff optimisation, self consumption or battery backup.
The below diagram shows AC wiring only and indicates the customer circuits; some of which are battery back-up
protected, some are grid supply only.
Rev.1.12 27 | P a g eAttention must be paid to the Neutral conductor and connection through to the loads. The neutral conductor connecting
to the loads must be maintained such that operation of the inverter isolator would not alter the bonding between Neutral
and Earth.
The Neutral conductor must remain connected through to the loads and particular care should be taken with the
placement of RCDs. These devices open both Active and Neutral conductors thus the SP PRO must be installed on the grid
side of these devices.
Note: This diagram is given as a reference only. Please ensure all wiring complies with relevant safety standards.
DANGER!
The M48-Select MUST be earthed. Earthing the M48-
Select will earth the batteries inside the system,
which will protect the system against faults. The
M48-Select has 1m of 6mm² cable protruding from the top
of the enclosure. Connect this earthing cable to the SP PRO
earth terminals (either Grid or Load side earth) to earth the
M48-Select.
Rev.1.12 28 | P a g eThe final connected AC earthing, Neutral, Grid, Loads and
DC positive and Negative wiring should look like this:
