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
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.
