300W Portable Folding Solar Blanket Operational Instructions

1. Step 1 – Unfold & position the blanket in the sun
   Locate the blanket in a position where it is exposed to the sun for the majority of the day. For best results use a northern orientation. The panel will function in the horizontal or hung position, however for best performance tilt the panels so they directly face the sun.

2. Step 2 – Connect to the battery
   Connect the 5m lead to the battery – red clamp to the positive ( + ) terminal and black clamp to the negative ( – ) terminal. The solar blanket will now be charging the battery under regulation.

Solar Controller Operation

• Step 1: Connect the battery. If the connection is correct, the controller screen lights up; otherwise, check whether the connection is correct.
• Step 2: If sunlight is present and strong enough (the solar panel voltage is greater than battery voltage), the sun icon on the LCD screen is on; otherwise, check whether the connection is correct.

Solar Controller Specifications

The KT 20A, 12V Solar Charge Controller is designed to charge Deep Cycle Batteries. Suited to charge Lead Acid, Gel, AGM, Lithium & Calcium Battery types, this Solar Charge Controller prevents batteries from becoming overcharged. The unit provides an automatic equalisation feature for all battery chemistries. The PWM Solar Charge Controller features a digital LCD to directly display battery voltage, charging current, charging capacity, percentage present, battery type, fault codes. Coloured LED’s indicate the operational status and each battery conditions. KT’s range of solar regulators are PWM (Pulse Width Modulation) which are the most commonly used, making them suitable for use on panels that are constantly being transported or moved eg; on the roof of a caravan, fitted to the back of a transportable, folding solar panel etc. PWM solar chargers use technology similar to other modern high- quality battery chargers. When a battery voltage reaches the regulation set- point, the PWM algorithm slowly reduces the charging current to avoid heating and gassing of the battery, yet the charging continues to return the maximum amount of energy to the battery in the shortest time. The result is a higher charging efficiency, rapid recharging, and a healthy battery at full capacity.

Solar Charge Controller

• Advanced MCU control Pulse Width Modulated (PWM) technology, high efficiency operation.
• Suitable for Lithium, GEL, AGM, Conventional Lead-Acid (WET) and Calcium Batteries.
• Built in regulator to prevent your battery from being overcharged. Overcharging occurs when the charge voltage is unregulated. This can result in premature battery failure.
• The regulator prevents your battery from being under charged, in the solar energy field, battery undercharge always occurs, especially on some conventional lead-acid or calcium batteries. The unit provides an automatic equalization feature for deeply drained conventional lead-acid battery or calcium battery, as well as provides a cycling automatic equalizing feature every 28 days.
• Can be connected to the battery permanently to keep the battery fully charged by using a process called “floating”. This means the controller will stop charging when the battery is full and will automatically start charging the battery as required. This process will also reduce water loss and help prevent the battery from ‘drying out’.
• Protects your battery from discharge at night. Under low light or no light conditions the solar panel voltage could be less than the battery voltage. The unit contains a special circuit which prevents current flowing back from the battery and into the solar panel.
• Coloured LED’s to easily indicate the operational status and battery conditions.
• Digital LCD to directly display battery voltage, charging current, charging capacity (Amp hour), battery types, full charge and faulty codes.
• Multi-charging protections against reverse polarity, short circuit, over temperature, over voltage, etc.

Wiring Connections

To protect the Battery and the Solar Panel, we strongly recommend that you place inline fuse on the positive wire on both the “Solar” and “Battery” Circuits. 20A fuse for 10A controller, 30A fuse for 15A controller, 40A fuse for 20A controller, (As close to the Battery / Panel as possible). The Solar Controller has 4 terminals which are clearly marked ‘Solar’ and ‘Battery’. There is a (12V / 24V) and earth (GND) terminal for each circuit.

Refer to the wiring diagram below.

Display Features

Please check your battery manufacturer’s specifications to select correct battery type. The unit provides 5 battery types for selections: Gel, AGM, WET (conventional lead acid), Lithium and Calcium. Press BATTERY TYPE button and hold for 3 seconds to go into your battery type selection mode, the battery type you select will be shown on the LCD meter, the default setting is AGM Battery; the controller will automatically memorize your battery type setting. Caution: Incorrect battery type setting may damage your battery. When the controller powers on, the unit will run self-qualify mode and automatically show below items on LCD before going into charging process.

After going into charging process, the LCD displays the charging states as below: Press VOLT / AMP button in sequence, the LCD will display in turn with Battery Voltage, Charging Current, Charged capacity (Amp-hour) and Battery Temperature (if external temperature sensor connected)

Display in the day time-

Display during the night

Alternatively Display voltage and FUL when battery is fully charged

• The VOLT / AMP button can be changed at any time during charging process.
• The LCD also can be treated as an independent voltage meter or thermometer.
• A voltage less than 11.5V Volts (for 12V battery) indicates that the battery is discharged and needs re-charging.

CHARGING STAGES OPERATION – L.E.D. INDICATION
The unit has a 5 stage charging algorithm.

• Soft Charge (Level 1)
• Bulk Charge (Level 2)
• Absorption charge (Level 3)
• Equalizing Charge* (Level 4)
• Float Mode (Level 5)

CHARGING STAGES

• Soft Charge – When batteries suffer an over-discharge, the controller will softly ramps the battery voltage up to 10V for 12V battery.
• Bulk Charge – Maximum current charging until batteries rise to Absorption level
• Absorption Charge -Constant voltage charging and battery is over 85%.
• Equalisation Charge – Only for WET battery or Calcium battery type, when the battery is deeply drained below 10V (for 12V battery), it will automatically run this stage to bring the internal cells as an equal states and fully complement the loss of capacity. (Gel and AGM battery do not run Equalization charge)
• Float Charge – Battery is fully charged and maintained at a safe level. A fully charged battery has a voltage of more than 13.6 Volts (for 12V battery).

Product Care

1. Periodically inspect the electrical and mechanical connections. Make sure they are all tight and free from corrosion. If necessary clean the surface of the solar panels with a soft damp cloth. Mild detergent can also be used. Any dirt or residue on the solar mat may effect performance.
2. Always fold-away for storage when not in use

Product Safety

Always follow user manual for operational and safety instructions.

1. For installations with all batteries, avoid sparks or flames near the batteries and always use proper eye protection.
2. Given sufficient light, solar panels always generate energy even when they are disconnected.
3. Accidental ‘shorting’ of the terminals or wiring can result in sparks causing personal injury or a fire hazard.
4. Do not scratch or stand on solar cells.
5. Do not disassemble the Solar kit.
6. Do not attempt to increase module output by concentrating light on its surface with mirrors.
7. When storing the KT Solar Blanket – to avoid damage, do not pack heavy items on top.
8. Do not disassemble the controller. Take to a qualified electrician if the unit requires repairing.
9. The solar regulator is IP65 rated, however solar blankets should not be left overnight during rainfall. They should be folded up and put away each evening to ensure longevity. In the event the blanket is completely saturated, simply hang up and dry just like a blanket.
