WARNINGS !CAUTIONS!
1. This Charge Controller is not waterproof (Ingress Protection Rating is IP-30). PLEASE
ENSURE THAT THE UNIT IS INSTALLED IN DRY, COOL AND WELL VENTILATED ENVI-
RONMENT.
2. Ground the Negative of the battery as follows:
• to Earth Ground in shore installations
• to Chassis Ground in Negative grounded mobile installations
3. There are no user serviceable parts inside the controller. Do not disassemble or
attempt to repair it.
4. Install external fuses / breakers as required.
5. Disconnect the PV Panel(s) and fuse / breakers near to battery before installing or
adjusting the controller.
6. Conrm that power connections are tightened to avoid excessive heating from
loose connection.
7. The charge controller has been set to optimally charge 12V / 24V Lead Acid
Batteries (Sealed/AGM)
8. Comply with battery manufacturer’s recommendations.
9. Avoid charging damaged, defective or old battery.
10. Ensure correct polarity is maintained when connecting the Charge Controller to the
battery - Connect the Positive output terminal to the Positive Battery Post and the

SECTION 1 | Safety Instructions
12. Batteries contain very corrosive diluted Sulphuric Acid as electrolyte. Precautions
should be taken to prevent contact with skin, eyes or clothing. If battery acid
makes contact with skin or clothing, ush immediately with water. See a doctor
immediately.
13. Batteries generate Hydrogen and Oxygen during charging resulting in evolution of
explosive gas mixture in non-sealed batteries. Care should be taken to ventilate the
battery area when non-sealed batteries are used and follow battery manufacturer’s
recommendations.
14. Ensure there are no ammable substances, explosive gases, ames, smoke or spark
near the battery or the PV Panel(s).
15. Use caution to reduce the risk of dropping a metal tool on the battery. It could
spark or short circuit the battery or other electrical parts and could cause an
explosion.
16. Remove metal items like rings, bracelets and watches when working with batteries.
Batteries can produce a short circuit current high enough to weld a ring or the like
to metal and thus cause a severe burn.
17. If you need to remove a battery, always remove the ground terminal from the bat-
tery rst. Make sure that all the accessories are off so that you do not cause a spark.
18. PV Panel(s) generate electrical power when exposed to sunlight. Place a dark cover
over the panels when handling panels that have bare, un-insulated output wires.
Accidental shorting of panel terminals or wiring connected to the panels can result
in spark causing personal injury or a re hazard.
19. It is important that the battery gets fully charged frequently (at least once per
week). Otherwise, the battery can become permanently damaged due to under
charging. Partially charged batteries can quickly sulfate internally which is an ir-
reversible condition. It is good practice to prevent a battery from being discharged
below 50%. Deeper discharging severely shortens battery life.
20. Keep the surface of PV Panel(s) clean from dust. Clean with a soft cloth. Do not
walk on the panels.
21. Installation and wiring must comply with the local and National Electrical Codes
and must be done by a certied electrician.

3.4.1 Step1: Battery Connection
WARNING!
RISK OF EXPLOSION OR FIRE! NEVER SHORT CIRCUIT BATTERY POSITIVE (+)
AND NEGATIVE (-).
MISE EN GARDE!
RISQUE D'EXPLOSION OU D'INCENDIE! NE COURT-CIRCUITEZ JAMAIS LA
BATTERIE POSITIF (+) ET NÉGATIF (-).
Refer to Fig 3.2
Before the battery is connected, make sure that battery voltage is greater than 8V so
as to start up the controller. If the battery system voltage is 24V, make sure the battery
voltage is not less than 18V to ensure that battery system voltage is correctly sensed as
24V (auto sensing feature for battery system voltage will erroneously sense voltage <
18V as 12V battery system). Battery system voltage will be sensed automatically when
the controller starts up for the rst time. 15A fuse "F1" is used to protect the cable run
from the battery to the charge controller against short circuit. Install the fuse not more
than 7" from the battery Positive terminal. Do not insert the fuse at this time.
3.4.2 Step 2: Load Connection through Load Terminals (Limited to 10A)
Refer to Fig 3.2
The Load Terminals of the controller can be connected to such electrical devices as lights
and other devices with load current of up to 10A. Controller provides power to the
load(s) through the battery.
When load(s) are fed from the Load Terminals, the controller will provide the following
protections on the load side:
Protect the battery as follows:
- Battery Low Voltage Alarm (≤12V/24V): Battery Status LED (2, Fig 2.1) will be steady OR-
ANGE. Output will still be available at Load Terminals. This condition will be auto reset at
12.2 / 24.4V
WARNING!
CURRENT OUTPUT ON THE LOAD TERMINALS IS LIMITED TO A MAXIMUM
OF 10A. IF HEAVIER LOADS DRAWING MORE THAN 10A LIKE INVERTER ETC.
ARE REQUIRED TO BE POWERED, CONNECT THEM DIRECTLY TO THE BATTERY
THROUGH APPROPRIATE FUSE "F2" THAT SHOULD MATCH THE DC INPUT CUR-
RENT OF THE INVERTER. THIS FUSE SHOULD ALSO BE INSTALLED WITHIN 7" OF
THE BATTERY (+) TERMINAL.
