STEP 3: Solar Battery Charge Controller Install
The system includes an ad-
vanced PWM charge controller
with LCD display. The control-
ler mounts on the backplate
using two or four #8 x 3/8” pan
head self tapping screws. This
controller maintains proper
charge parameters over tem-
perature to extend battery life
and enables the system to be
Solar Ready™. Solar panels
can be added at any time to
extend backup time or provide
a backup power source to
keep the batteries fully
charged.
The kit includes two Cable
Gland Feedthroughs. Remove
one or two hole plugs in the
bottom of the enclosure and
replace with one or two cable
gland feedthroughs to be used
to route external wires.
Attach the included battery cable to the controller BAT inputs. (Red to +
and Black to –).
Note: The battery cable is different if 12V or 24V configuration. For 12V
all batteries are wired in parallel. If 24V, each pair of batteries is wired
in series and both series pairs are wired in parallel.
Connect the bare wires of the short cable that came with the Battery
Charger to the BAT inputs of the Controller in parallel with the battery
cables. Be sure to maintain polarity. Black wire to BAT-.
Connect the wires for any equipment, that will be powered by the sys-
tem, to the controller load output.
Mount the controller inside the enclosure with included screws.
STEP 4: Battery Charger Install
The battery charger is an AC input battery charging power source. The
output voltage of the battery charger must match the battery voltage,
either 12V or 24V.
Be very careful. Never work with live circuits. Consult a licensed
electrician for AC connection.
The AC input of the battery charger is an attached AC power cord. The
plug can be cut off, if desired, to connect to an AC input wire directly,
