3.2 Mounting
NOTE: When mounting the controller, ensure free air
through the controller heat sink fins. There should be at
least 6 inches (150 mm) of clearance above and below the
controller to allow for cooling. If mounted in an
enclosure, ventilation is highly recommended.
WARNING: Risk of explosion! Never install the
controller in a sealed enclose with flooded batteries! Do
not install in a confined area where battery gassed can
accumulate.
Step 1: Choose Mounting Location
Locate the controller on a vertical surface protecte from irect sun, high
temperature, an water. An make sure goo ventilation.
Step 2: Check for clearance
Place the controller in the location where it will be mounte . Verify that
there is sufficient room to run wires an that there is sufficient room above
an below the controller for air flow.

Step 3: Mark Holes
Use a pencil or pen to mark the four (4) mounting hole locations on the
mounting surface.
Step 4: Drill Holes
Remove the controller an rill 4mm holes in the marke locations.
Step 5: Secure Controller
Place the controller on the surface an align the mounting holes with the
rille holes in step 4.
Secure the controller in place using the mounting screws.
3.3 Wiring
NOTE: A recommended connection order has been
provided for maximum safety during installation.
NOTE: The controller is a common positive ground
controller.
CAUTION: Don’t connect the loads with surge power
exceeding the ratings of the controller.
CAUTION: For mobile applications, be sure to secure
all wiring. Use cable clamps to prevent cables from
swaying when the vehicle is in motion. Unsecured
cables create loose and resistive connections which may
lead to excessive heating and/or fire.

WARNING: Risk of explosion or fire! Never short
circuit battery positive (+) and negative (-) or cables
Figure 3-2 Battery connecting
Before battery is connecte , make sure that battery voltage is greater than 6V
so as to start up the controller. If system is 24V, make sure battery voltage is
not less than 18V. System voltage can only be automatically recognize
when controller start up for the first time.
When install fuse, make sure that the biggest istance between the fuse
hol er an the positive terminal of battery is 150mm. Do not insert a fuse at
this time. Confirm the connection correct an turn on the power.

WARNING: Risk of electric shock! Exercise caution
when handling solar wiring. The solar module(s) high
voltage output can cause severe shock or injury. Be
careful operation when installing solar wiring.
The controller can accept12V, 24V nominal off-gri solar mo ule(s).
Gri -tie solar mo ule(s) may be use if the open circuit voltage of solar
mo ule oesn’t excee the Maximum PV input voltage of the controller.
The solar mo ule(s) work voltage must be equal to or greater than the
system voltage.

4 Operation
4.1 PWM Technology (Series Pulse Width Modulation)
The controller a opts the a vance series pulse wi th mo ulation (PWM)
charging mo e. With range of 0-100%, it can charge the battery quickly an
stably un er any con ition of solar photovoltaic system.
PWM charging mo e use automatic conversion uty ratio pulses current to
charge the battery. The battery can be fully charge safety an rapi ly with
the pulse current. Intermissions make some oxygen an hy rogen generate
by chemical reaction chemically combine again an absorbe . It can
eliminate concentration polarization an ohm polarization naturally an
re uce the internal pressure of the battery so that the battery can absorb more
power. Pulse current charging mo e makes battery have more time to react,
which re uces the gassing volume an makes battery improve the
acceptance rate of charging current.
4.2 Battery Charging Information
Figure 4-1 PWM Charging mo e
·Bulk Charge
In this stage, the battery voltage has not yet reache boost voltage an 100%
of available solar power is use to charge the battery.
·
Solar Charge Controller 6830-122-C10/15/20
2013-06-25 1 Version 6
·Boost Charge
When the battery has recharge to the Boost voltage set point, constant-
current regulation is use to prevent heating an excessive battery gassing.
The Boost stage remains 120 minutes an then goes to Float Charge.
·Float Charge
After the battery is fully charge in Boost voltage stage, the controller
re uces the battery voltage to Float voltage set point. When the battery is
fully recharge , there will be no more chemical reactions an all the charge
current transmits into heat an gas at this time. Then the controller re uces
the voltage to the floating stage, charging with a smaller voltage an current.
It will re uce the temperature of battery an prevent the gassing, also
charging the battery slightly at the same time. The purpose of Float stage is
to offset the power consumption cause by self consumption an small loa s
in the whole system, while maintaining full battery storage capacity.
In Float stage, loa s can continue to raw power from the battery. In the
event that the system loa (s) excee the solar charge current, the controller
will no longer be able to maintain the battery at the Float setpoint. Shoul
the battery voltage remains below the boost reconnect charging voltage, the
controller will exit Float stage an return to Bulk charge.
·Equalize Charge
WARNING: Risk of explosion!
Equalizing flooded battery can produce explosive
gases, so well ventilation of battery box is necessary
NOTE: Equipment damage!
Equalization may increase battery voltage to the level
damaging to sensitive DC loads. Ensure that all load
allowable input voltages are greater than the equalizing
charging set point voltage.
Solar Charge Controller 6830-122-C10/15/20
2013-06-25 2 Version 6
NOTE: Equipment damage!
Over-charging and excessive gas precipitation may
damage the battery plates and activate material
shedding on them. Too high an equalizing charge or for
too long may cause damage. Please carefully review the
specific requirements of the battery used in the system.
Certain types of batteries benefit from perio ic equalizing charge, which can
stir the electrolyte, balance battery voltage an complete chemical reaction.
Equalizing charge increases the battery voltage, higher than the stan ar
complement voltage, which gasifies the battery electrolyte.
If the battery is being over ischarge , the solar controller will automatically
turn to equalize charging stage, an the equalize stage remain 120mins.
Equalize charge an boost charge are not carrie out constantly in a full
charge process to avoi too much gas precipitation or overheating of battery.
