1. INTRODUCTION
Thank you for purchasing the KISAE Solar Charge Controller. With our state of
the art, easy to use design, this product will offer you a reliable service to
convert your PV solar energy to charge you battery in an effective and efficient
way. It also protects your battery from overcharge by the PV or over discharge
(LD model only) through the DC load connected.
2. PRODUCT DESCRIPTION
The KISAE Solar Charge Controller package includes the items list below.
Solar Charger controller
Owner’s manual
3. Important Safety Instructions
This section contains important safety information. Before installing or using
the unit, READ ALL instructions and cautionary markings on or provided. The
unit contains no user-serviceable parts. See Warranty section for how to
handle product issues.
FIRE AND/OR CHEMICAL BURN HAZARD
Do not cover or obstruct any air vent openings and/or install in a
zero-clearance compartment.
FAILURE TO FOLLOW THESE INSTRUCTIONS CAN RESULT IN DEATH
OR SERIOUS INJURY
When working with electrical equipment or lead acid batteries, have
someone nearby in case of an emergency.
Wear eye protection and gloves.
Avoid touching your eyes while using this unit.
Keep fresh water and soap on hand in the event battery acid comes in
contact with eyes. If this occurs, cleanse right away with soap and water for
a minimum of 15 minutes and seek medical attention.
Batteries produce explosive gases. DO NOT smoke or have an open spark
or fire near the system.
Keep unit away from moist or damp areas.
Avoid dropping any metal tool or object on the battery. Doing so could
create a spark or short circuit which goes through the battery or another
electrical tool that may create an explosion.
WARNING: Explosion hazard!
DO NOT use the unit in the vicinity of flammable fumes or gases (such as
propane tanks or large engines).
Prolonged contact to high heat or freezing temperatures will decrease the
working life of the unit.
Use only with 12 V battery and do not exceed the voltage and current
ratings of the unit.
Use only with PV array rated for 12V battery. Do not short circuit the PV
array and or the load while connected to the unit. This will permentantly

damage the unit.
Protect the unit from direct sunlight.
Unit should be properly grounded. Grounding should comply with local
codes.
Do not connect and disconnect the unit when the circuit is live.
4. Understanding the unit

To PV Panel To Battery To DC Load
The first pair of screw terminals is the input terminal for solar panel connection.
The second pair of screw terminals is the bi-directional terminal used for
battery connection. This acts as an output terminal for battery charging from
the PV panel through the unit and acts as an input terminal for battery
discharging to DC load through the controller.
The third pair of screw terminals is the output terminal for DC load connection.
Note: Use the jumper provided to connect terminal 6 and 7 for sealed battery
type.
‘Charging’ green indicator turns on when PV solar panel provides enough
energy for battery charging. It turns off when sunlight is not available or
insufficient to charge the battery.
‘Load Disconnect’ indicator (LD models only) turns on when battery charge is
low and the Load Output is disconnected from the battery. The Load Output
will automatically reconnect when the battery voltage is charged to above
12.6V.
5. Installation Instructions
CAUTIONS: Please verify the rating of the PV panel size, battery voltage type
and the total power consumption of the DC load before installing the unit.

SC 1210LD 12V, 10 ADC with load disconnected
SC 1220LD 12V, 20 ADC with load disconnected
Step 1: Select Battery type
Factory default setting with jumper installed is for sealed battery type. For
the use of flooded battery, remove the installed jumper.

Step 2: Connecting a 12V battery
Connect ‘-‘ terminal of Energy Storage (pin 4) on unit to 12V battery
negative terminal
Connect ‘+’ terminal of Energy Storage (pin 3) on unit to 12 V battery
positive terminal
Step 3: Connecting a PV panel
Connect ‘-‘ terminal of Solar Input (pin 2) on unit to PV panel negative
terminal
Connect ‘+’ terminal of Solar Input (pin 1) on unit to PV panel positive
terminal
Step 4: Connecting a DC load
Connect ‘-‘ terminal of Load Output (pin 6) on unit to PV panel negative
terminal
Connect ‘+’ terminal of Load Output (pin 5) on unit to PV panel positive
terminal
Note: Maximum wire size of AWG#10 can be used on the terminal and tighten
the screws snugly.
6. Operation and Maintenance
The unit is fully automatic and no unit setting is required once it is installed
properly. It is recommended to verify the state of charge of the battery regularly
and to verify that the load connected to the unit is not over rated for the unit. It
is also recommended to verify that the power consumption on the load is less
that the PV panel can produce.
The following periodic inspections and maintenance tasks are highly
recommended for best performance.
Check for any rusting or corrosion around the battery terminals
Verify the PV panels and loads connected do not exceed the unit rating
Tighten all the 7 terminal screws and inspect for any loose, broken or
burnt wire connections.
Ensure PV panel is mounted properly and is placed in the right position.
Check for any dirt, debris and corrosion on the panel.
Periodically clean solar panels with water and do not use chemicals
7. Troubleshooting
No Output:
Check DC load terminal connection. Connection may be loose or
disconnected.
Check connection polarity. Reverse polarity on any terminals will damage
unit and is not covered by warranty.
Verify battery voltage is not too low.
For LD model, check Load disconnect LED is ON. Verify battery voltage
is above 12.6V.
Battery did not charge:
Verify the PV panel is functioning properly. Check for poor connection on
the PV panel
Verify PV panel is not blocked by any surrounding tall objects. Check the
PV panel surrounding area.
Check PV and battery connection. Loose connection will reduce unit
performance.

Check connection polarity. Reverse polarity on any terminals will damage
unit and is not covered by warranty.
Verify the DC load consumption. The power consumed by the DC load
should be less than the PV panel generates.
