INSTALLATION MANUAL

Introduction:
The DCS PV Series packs are designed primarily for efficiently
storing photovoltaic energy produced by solar systems.
1
BATTERY MANAGEMENT SYSTEM (BMS):
All DCS PV Series battery packs feature an advanced
internal BMS. The BMS constantly monitors the packs
operation and prevents the battery from operating
outside design parameters.
DCS batteries do not require a communication link to
operate correctly.
Supercharging BMS capability allows the batteries to
be recharged at up to 3 times the recommended
charging current but must never exceed 100Amps.
EXPANDABILITY:
The battery packs can be easily expanded by making
additional parallel connections across the battery
connection terminals. Up to 3 parallel connections
can be made across each positive and negative set of
terminals.

Performance specifications & charging currents:

Refer to the label on the side of the battery pack to confirm the model and specifications.
DCS PV 5.0 / DCS PV 5.0W
Recommended charging
current 40Amps when
connecting a single PV 5.0
(100Ah) battery to an inverter.
If a second PV 5.0 (100Ah)
battery is added in parallel
making the combined total
capacity (200Ah) the charging
current can be doubled and
increased to 80Amps.
If the combined capacity of the
batteries will be equal to or
over (300Ah) than the charging
current can be set to 100Amps.
The maximum charging and
discharging current can never
exceed 100Amps.
DCS PV 10.0 / DCS PV 10.0W

If a second PV 5.0 (100Ah) OR
PV 10.0 (200Ah) battery is
added in parallel making the
combined total capacity equal
to or over (300Ah) the charging

Cable requirements: minimum 4 AWG (21mm2) or
minimum continuous rating 130Amps
Cable Ring Terminals/Lugs: M8
Cable length: keep under 3.0 meters, position battery
as close to the charge controller as possible to minimise
any voltage drop in the cables.
Installation location & environment: the optimal
temperature range for the battery pack to operate and
to maximise the lifespan is between 0 to 45 degrees
Celsius.
However the battery pack will continue to operate
between -20 to 65 degrees Celsius temperatures. If
ambient temperatures are outside the -20 to 65
operating range, the battery will automatically stop
operating and go into protection mode. Once the
correct operating temperature range is again present
the battery pack will begin to operate correctly.
International Protection Rating: IP-67
6 =
Dust tight
7 =
Immersion, up to 1m depth
Due to the design of the batteries being fully sealed
against dust and water, this provides many installation
possibilities. Whenever possible the best practice is to
have the batteries positioned in well ventilated cool
locations. Such as those found on the south-facing walls
of buildings and houses. Avoid direct sunlight. When
installing batteries under houses or verandas/deckings
ensure the environment is dry and free from dampness.
Always position the batteries on top of pavers and don’t
just leave them in the dirt.
When installing indoors avoid rooms that experience a
high daily change in ambient temperature. Such as non-
insulated or non-ventilated sheds or garages.
Installing the battery packs: mounting to a wall, only
the DCS PV W series of batteries can be wall mounted.
The W series batteries have an internal passive
thermodynamic architecture that provides superior
cooling capabilities and will only work when these
batteries are wall mounted.
There are M10 predrilled and slotted holes along each
edge of the batteries for correct wall installation. Use
M10 bolts for solid walls (masonry/brick) that are at
least 50mm in overall length and drill suitable holes.
Installation
- Ipsum
For installation into timber walls or studs use couch
screws that are minimum of 50mm in length. Predrill
hardwood with M4 – M8 drill size to ensure the timber
doesn’t split when the bolts are fastened.
Secure/drive the M10 bolts through the predrilled
slotted battery holes using washers into the prepared
surface holes.
Tighten the bolts or nuts using a 8Nm torque wrench.
Connecting the battery pack to the inverter:
1. Make sure the inverter/charge controller is
turned off before connecting the battery pack
to the inverter.
2. To connect the power cables coming from the
inverter/charge controller remove the
protective terminal plate covers located on the
battery packs. Note the positive and negative
terminals marked with “+” “-“ and their
corresponding cable gland colors “red” and
“black”
3. Feed each positive and negative power cables
through the cable gland entries, pull through
about 30cm of cable length to make it easier to
clean the insulation and prepare the terminals.
4. Strip back around 12mm of insulation from the
cables or enough to make sure the copper
reaches the very tip of the ring terminals/cable
lugs. Crimp the ring terminals/lugs using the
correct sized crimping tool and finish with some
insulation tape to ensure none of the copper is
exposed to atmosphere.
5. Remove the battery terminal hex
screws/washers and pull the cables back to
locate the ring terminals/lugs centrally onto the
battery terminals.
6. Tighten the hex terminal screws to a torque of
6Nm and restore the terminal plate covers.
7. Tighten the cable glands securely to ensure a
water/dust tight finish.
8. Ensure the inverter/charge controller is setup
using a lithium charging profile with the correct
cycling voltages enabled 44.5V ~ 58.4V and
correct charging/discharging currents before
switching it on.

5
The battery packs can be easily expanded by making additional parallel connections across the
battery connection terminals. Up to 3 parallel connections can be made across each positive
and negative set of terminals.
1. Make sure any existing batteries are disconnected/isolated from the inverter/charge
controller.
2. Loosen the cable glands, remove the terminal plate covers and remove any existing
cables/ring terminals from the connection boxes.
3. Using a stepped drill bit, drill an additional hole along one of the free side walls of the
connection boxes which would be 90 degrees to any existing connections. Drill the
correct sized hole so that the new M25 cable glands fit snug.
4. Remove any metal filings from the connection boxes using a pressurised air canister.
5. Create any new connections and restore any existing connections, tighten the
connection terminal screws, restore the plate covers and tighten all cable glands
securely to ensure a water/dust tight finish.
