Model SRY-002-1 Lighting Kit

 The Model SRY-002-1 is a slightly enhanced version of the basic Model SRY-001E lighting Kit and consists of one LED light, a mobile phone charger & a separate battery charging compartment where rechargeable batteries can be charged for use in separate portable radios or torches.
The Solar PV Panel consists of a 9V/1.5W solar module with a 5M cable that provides flexibility in being able to suitably locate the Solar Panel to maximise the solar input during the daylight hours, and still have enough length in the cable to extend the light to a point where it can be best utilized.  The Solar PV module has a life cycle of approximately 10 years and is warranted for 5 years.  The inbuilt controller provides protection against over-charging and over-discharging and also includes short-circuit protection.    The battery pack consists of 5pieces of AA size x 1000mAH NI-MH (Nickel Metal Hydride) rechargeable batteries that are housed in a strong UV stabilized, heat resistant ABS plastic material for durability and longer life.   The LED Lamp that is supplied with the kit is a 1piece x 9V with 18 Light Emitting Diodes (LED) together with a 4M cable.  A Mobile phone Charger connection in the battery pack allows direct mobile phone charging and several different types of plugs are supplied with the kit to cover most popular types of mobile phones.

In addition the Model SRY-002-1 has a separate compartment provided in the front of the ABS battery pack where two (2) 600mAH NI-MH rechargeable batteries, that are supplied with the kit can be charged during the daylight period as well.   These batteries can be used in a flashlight or a portable radio.    After the solar PV module has been charged for between 6-8 hours there are three brightness setting options that can be used for the LED light.   The three settings will offer the following performance: maximum brightness around 6 hours, energy saving mode around 12 hours, and low brightness mode approximately 50 hours of operation.   The Model SRY-002-1 instruction manual is available in English and French and dependent upon quantities other languages are available as well.   Each Kit weighs approximately one kilogram and is packed in a strong packaging box measuring 245mm x 195mm x 510mm.   Standard Packs comprise of 10 pieces per carton which measures 410mm x 280mm x 255mm and has a gross weight of around11 Kg.

Multi-Function Heat Pumps

Multi-Function Heat Pump
The Multi-Function Heat Pump is a patented product with multi-usage functions.  They use a suitably sized Heat Pump module to deliver hot water, via an insulated storage tank as well as cooling (air conditioning), via a small buffer tank from one split type Heat Pump module.  
The use of energy efficient Japanese brand Mitsubishi, Panasonic, and Sanyo rotary or scroll compressors, depending upon the product capacity needed, as well as two (2) separate high efficiency plate heat exchangers, this combination significantly improves the energy efficiency to the point where the combined Coefficient of Performance (COP) for the heating and the cooling functions can be as high as seven (7) which represents an energy saving of 700% when compared to the electrical energy that would be consumed by separate electrical hot water system and air conditioners delivering the same volume of cool air and the same volume of hot water each day.  Whilst the electricity tariff supplied by the local utilities in any Region will still be the same the “effective” tariff would be 7 times less to deliver the same performance due to the efficiency of the combined Multi-Function Heat Pump Units.  For example if the actual tariff was the equivalent of US $0.12 cents per kWh then the “effective” tariff would be approximately US $0.02 cents per kWh.

Multi-Function Heat Pump - Operation Schematic
The built-in circulating pumps are the World renowned and reliable Wilo brand and they provides automatic water level control, and automatic water pressure controls.   The Multi-Function Heat Pumps also have inbuilt hot water flow and air flow controls, compressor exhaust temperature protection as well as automatic defrost and load adjusting controls.  By using the high efficiency rotary or scroll compressors as well as low noise fans, the actual overall noise levels remain low.  Side fan or vertical fan discharge units are available as options.  LCD or LED touch screen controllers simplify the various settings to suit each individual installation with cooling water temperatures as low as 7°C and hot water temperatures of up to 60°C.  The Metran Multi-Function Heat Pump units are capable of operating in all weather conditions and ambient temperatures of between -15°C and +45°C.
