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.
Warning: Fire and/or Chemical Burn Hazard
• Do not cover or obstruct any air vent openings and/or install in a zero‐clearance
compartment.
Warning: 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 and 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 exposure to high heat or freezing temperatures will decrease the working life of
the unit.
• For SC1210LD and SC1220LD unit, use only with 12V battery systems.
• For SCD1230 unit, use only with 12V or 24V battery systems.
• Do not exceed the voltage and current ratings of the unit.
• For SC1210LD and SC1220LD, use only with solar array rated for 12V batteries (25V VOC
max.).
• For SCD1230, use only with solar array with 25V VOC max for 12V battery systems and solar
array with 50V VOC max for 24V battery systems.
• Do not short circuit the solar array and/or the load while connected to the unit. This will
permanently 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.
1. Introduction
Thank you for purchasing the KISAE PWM type Solar Charge Controller. With our state of the
art, easy to use design, this product will offer you a reliable service to convert your solar
energy to charge your low voltage battery system in an effective and efficient way. It also
protects your battery from overcharge by the solar panel or over‐discharge through the DC
load connected.
2. Product Description
The KISAE Solar Charge Controller package includes the items listed below.
• Solar Charger controller
• Owner's manual
3. Understanding the unit
For SC1210LD and SC1220LD model:
Caution: The SC1210LD and SC1220LD are designed for use with 12V Battery Systems only
1 2 3 4 5 6 7
To Solar Panel To Battery To DC Load
• Terminal 1, 2 are the input terminals for solar panel connection.
• Terminal 3, 4 are the terminals used for battery connection. That acts as output terminals
for battery charging from the solar panel and act as an input terminal for battery
discharging to DC load through the controller.
• Terminal 5, 6 are the output terminals for small DC load connection (if any).
Caution: Unit Damage!
Terminal 5 and 6 are designed for DC loads with current draw less than the rated current
of the unit like DC light bulbs and small DC appliances. Connecting loads with high surge
current or loads with current higher than the rated current of the unit, will permanently
damage the unit and will not be covered by the warranty. Heavy duty loads like Inverters
or DC Vacuum Cleaners should be connected directly to the battery terminals.
• To select battery type, use the jumper provided to connect Terminal 6 and 7 for charging
'Sealed' type of battery and do not use the jumper for 'Flooded' types of battery.
'Charging' green indicator starts to turns ON when it senses the solar panel provides more
than approximately 3.5V to let you know the solar panel works. With low Solar panel
voltage, it may not have sufficient energy to charge the battery. The Solar panel has to
have at least 0.2 to 0.3V above the battery voltage in order to charge the battery.
'Load Disconnect' indicator 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.
For SCD123 model:
Caution: This unit is designed for use with 12V or 24V Battery Systems only

Solar Panel Battery DC Load
• Terminal 1, 2 are the input terminals for solar panel connection.
• Terminal 3, 4 are the terminals used for battery connection. They acts as an output
terminal for battery charging from the solar panel and act as an input terminal for battery
discharging to DC load through the controller.
• Terminal 5, 6 are the output terminals for small DC load connection (if any).
Caution: Unit Damage!
Terminal 5 and 6 are designed for DC loads with current draw less than the rated current
of the unit like DC light bulbs and small DC appliances. Connecting loads with high surge
current or loads with current higher than the rated current of the unit, will permanently
damage the unit and will not be covered by the warranty. Heavy duty loads like Inverters
or DC Vacuum Cleaners should be connected directly to the battery terminals.
• Press once to temporary trigger ON the display to show unit status. You
• Press and hold for 3 seconds to enter unit setting mode
• During normal operation, press once to turn DC load ON or OFF
• Under unit setting mode, press once to proceed to the next setting
Battery type select:
• Under normal operation with display ON by pressing
• Under unit setting mode, press 'up' or 'down' arrows to adjust unit
4. Installation Instructions
Caution: Please verify the rating of the solar panel size, battery voltage type and the total
power consumption of the DC load before installing the unit.
