SYSTEM DESCRIPTION
Solar Photovoltaic Modules:
A solar photovoltaic module is the basic element of each photovoltaicsystem. It consists of number of solar cells arranged and connected in adefinite pattern. It converts solar energy into electrical energy whensunlight falls on its surface.

Solar Inverter Cum Charge Controller With Intelligent Logic Control:
Solar Inverter converts DC (Direct current)power from the battery to AC (Alternating current) power compatible withthe utility and AC loads. This unit consists of Solar Inverter cum Charge Controller with Intelligent Logic whichcontrols the charging of battery from solar or mains with solar aspriority.
This system monitors the Battery charge status and accordingly decides to charge the battery either from solar orfrom mains. First priority of charging is from solar modules and only in the absence of solar power (no-sunshinetime) and when battery voltage is low (a predetermined level), the mains charger is turned ON automatically. Thismaintains the battery on float.
When battery bank reaches a preset low voltage, mains charger turns "ON" and charges the battery bank. Next day, when solar radiation is available, the cycle repeats. This ensures healthiness of battery and hence the life of thebattery gets extended. Battery deep discharge, over charge protections are incorporated inside the Solar Inverter.

BATTERY
A device that converts the chemical energy contained in its active materials directly into electrical energy by meansof an electrochemical reaction. Low maintenance, tubular type batteries are provided with this system.

MODELS AVAILABLE
500Watt, 1KW, 2KW, 3KW, 5KW, 10KW

FEATURES
System designed for optimum performance.
Fully automated operation.
Add-on solar charging system available if home inverter is already installed - increase back-up time and save onpower bills.

Insulating Oil Testers are designed for the easy and accuratedetermination of the die-electric strength of insulating oils used intransformers, switchgears, bushings, capacitors and other electricalapparatus. They are ideal for on-site field and laboratory use.
HV Transformer
The HV transformer is a completely dry resin encapsulated transformerwith two HV terminals with mounting saddles. The midpoint of thetransformer HV winding is earthed so that the voltage of each terminal to
earth is only half the test voltage.
Safety
Maximum possible safety of the operator as well as the equipment isensured by a safety conscious design. The output controller isinterlocked at its minimum position so that HV can be switched ON onlywhen the voltage controller is at zero and the hood is shut. The outputcontroller must be brought to zero after every test or interruption. Thehood leading to HV terminals has a safety switch fitted so that openingof the hood shuts the HV OFF.
Cabinet
Portable, powder coated, sheet steel with lifting handles.
Test Cell model TC-2
The test cell with cover is made of Methyle Methacrylate ( Acrylic )having effective oil volume between 300 to 500ml with adjustable andremovable 36mm mushroom head electrodes to IS 6792 & IEC 156along with electrode gap distance GO & NOGO gauges, made of alloysteel, precision ground and hardened.

Solar energy originates in the depths of our sun. The sun endures a continuous stream of thermonuclear explosionsas hydrogen atoms are fused into helium atoms. We encounter the resultant energy as radiation that strikes thesurface of the earth. Solar panels convert this solar radiation into useful electrical energy and store them in batteriesfor our use. Enough solar radiation strikes the earth every day to meet earth's energy needs for an entire year. Solarpanels, help us harvest this energy and convert it into usable energy to meet the everyday needs of modern life.

WHAT ARE SOLAR PANELS MADE OF?
Solar panels are typically constructed with crystalline silicon, which is used in other industries also. Solar Panels are aform of active solar power, a term that describes how solar panels make use of the sun's energy: solar panels harvestsunlight and actively convert it to electricity. Solar Cells, pr photovoltaic cells, are arranged in a grid-like pattern in asolar panel.

On Grid Solar Power Plant Available for all Wattage Requirement on Per Wattage Basis.

The sun is an inexhaustible, reliable, non-polluting source of power. Concerns over global climatic change, local airpollution, and resource scarcity make photovoltaic (PV) an increasingly attractive energy supply technology. Usingsolar energy with LEDs instead of CFLs provides a very efficient solution.
Solar powered outdoor lighting products are ideal for lighting the area in remote locations where the electricity isunavailable or erratic. Even in urban areas, these find great usage to reduce dependency on conventional power andcontribute towards green energy. Reliable and long life makes this solution effective in fulfilling our present andfuture lighting requirements.
