There are two main types of convertor's:

will accept a modified sine wave as voltage input [10].

DC/DC converters transform a continuous voltage to another continuous voltage

Inverters are used when your equipment requires AC power. Inverters chop and invert the DC current to generate a square wave that is later filtered to approximate a sine wave and eliminate undesired harmonics. Be aware that not all the equipment

The load (microscope) is the equipment that consumes the power generated by your energy system. The load may include medical equipments, routers, workstations, lamps, TV sets, etc. In this type of system it is absolutely necessary to use efficient and low power equipment to avoidwasting energy. It should be obvious that as power requirements increase, the expense of the photovoltaic system also increases.

Is an instrument used to see objects that are too small to be seen by the naked eye [11], optical instrument that have a magnifying lens for inspecting objects which are too small to be seen by human's eyes. Microscopes are used to observe the shape of bacteria, fungi, parasites and host cells in various stained and unstained

There are three main optical pieces in the compound light microscope. All three

It illuminates the object by converging a parallel beam of light on it from a built-
