LK20 Solar Indoor Lighting Kit

Available Options

This system is designed to be installed in homes or buildings in locations that do not have access to power. The system consists of a light fixture, some panel, battery, battery enclosure, charge controller, and remote controlled switch. The system can be supplied with one or two ceiling mounted light fixtures. Each light consumes 3 watts. Each system allows for 45 watt hours of daily use. That could be one 3 watt light on for up to 15 hours, or two 3 watt lights on for up to 7.5 hours. The solar panel is to be mounted on the roof, or in a location that receives full direct sun. The battery enclosure, which houses the remote control receiver, should be installed within 30' of the light fixture. The lights can be activated day or night with the use of the supplied remote controlled switch.

Technical Specifications

This system is capable of operating one or two LED lamps for up to several hours each night (subject to the quantity of lamps connected).
If two lights are connected to the system, the switch will activate both lights.
The system can accommodate up to 45 Watt hours of daily use.
Up to 3 days of autonomy (subject to system specifications, time length of illumination usage and other factors).

Light Fixture
Supplied with one or two ceiling mount light fixtures.
Each light is supplied with a 3 Watt LED bulb.
Offered in white, or warm white.
Light is supplied with 20' of cable for connection between light and battery enclosure.
Extension cables available upon request.
Light has a glass dome with stain nickle finished base.
Dimensions of light fixture are approx. 11.4" x 4.5".

Remote Control
A hand held 1-channel remote control is included to control the 1 lighting zone.
The remote control allows the user to switch the lights on or off.
Additional remote controls are available (if required) as an optional extra.
A 1-channel receiver unit is included (channel 1 = lighting zone 1).

This is a 12 Volt dc system.
A 12 Volt 18 Amp-Hr sealed lead acid battery is supplied.
Battery type is AGM. Gel batteries are available by special order.
The battery is approx. 8" x 8" x 3".

Battery Box
The battery box is approx. 12" x 9" x 6.5" (27cm x 20cm x 6cm).
A battery box is supplied to accommodate the battery.
The battery box can be used or installed indoors or outdoors. It may also be installed in a garage or in the attic or roof space.
The battery box also has a receptacle (socket) for a light fixture or lighting zone to be connected.

Solar Panel
A high quality, aluminum framed, 20 watt solar panel is included and is fitted with approximately 18' (5.5m) of cable/cord. Additional extension cable is available (upon request) as an option.
The solar panel can be installed on a roof, on a wall, on a patio or deck or just about anywhere where it can get direct sunshine.
The solar panel cord connects directly to the battery box.
Solar panel has a U shape support bracket to attach to a vertical or horizontal surface.
The 20w solar panel dimensions approx. 22.5" x 14" x 1" (57cm x 36cm x 2.5cm) (LxWxD).

Control Module
Supplied with a MPPT charge controller which automatically controls the solar panel power, battery charging and lighting function and operation.
Ultra fast Maximum Power Point Tracking (MPPT).
The MPPT charge controller is typically 30% more efficient than standard PWM controllers and 10% more efficient to most other MPPT controllers.
Additional efficiency for cloudy weather and during times of reduced sun radiation.
This controller features the very latest smart technology.
Provides extended battery life and extra protection against excessive battery discharge and overcharge.
Battery life algorithm operates 24/7.
Low voltage detection for automatic disconnect.
Continuous environment, input and output power management.
The controller is sized to the system specifications with 10A and 15A versions available (subject to solar panel wattage and battery capacity).
Lighting control features illumination from dusk to dawn (where applicable), or on at dusk for X amount of hours then off, or on at dusk for X amount of hours, then off, then back on again for X amount of hours before dawn.
Dimming option (where applicable) allows the lighting to dim at any time during the illumination time.
The dimming option or any other illumination mode can be used in conjunction with motion activation (where applicable).
Dimming may be at any percentage from 1-99%.

20 year solar panel warranty, 5 year warranty on all other components (excluding batteries). Batteries are covered by the manufacturer*.
Additionally, unlimited, lifetime technical support is available for all warranty registrations.

Please Note: This product is a special order and is non-returnable except in the event of a fault (during its warranty period) when the product, once returned will be repaired or replaced.

The solar panel must be installed in a location where it can receive full direct sunshine (when available) and usually set facing South at an appropriate angle (where adjustment options allow). The solar panel must not be installed in a shaded or part shaded location and never indoors. The standard specifications of the system (particularly the solar panel Wattage and battery capacity) may need to be adjusted. These components are determined by your geographic location, power consumption (LED Wattage) and the total amount of hours of illumination time required. Such changes to the standard specifications may increase or decrease the cost shown. Please contact us for more information or assistance. The illumination time is estimated and subject to various factors including (but not limited to) geographic location, seasons, temperature, weather conditions & location of product etc. The illumination time of most solar lights can reduce during winter months when the weather is poor and the days are shorter. During this time insolation hours decrease accordingly. Shorter illumination time due to one or more of the above factors does not define the product as being ‘defective’ or ‘not as described’. All solar lights must be used in a completely dark location at night time otherwise they may not illuminate. Nearby strong lighting sources or ambient lighting may affect the operation of a solar light. This does not define the product as being 'defective' or 'not as described'. Please note, if you do not install or use this product for several months the battery may discharge naturally on its own. By allowing a battery to deep discharge it may cause irreversible damage as the battery may then lose the ability to recharge or hold a full charge. Although unlikely, we reserve the right to supply this product with any minor alterations or minor changes to the specifications (shown above by text description or by photographs) due to different supplies or product batches received, incorporating such product changes made by the manufacturer, without further notice. Descriptions, specifications and photographs are updated regularly but may not be current when minor changes to a product have only recently been made.
