Inverters / Chargers

The solar inverter the €œbrains€ of the solar power system and therefore arguably the most important part is an electrical device that converts direct current (DC) to alternating current (AC) suitable for the electricity grid; the converted AC can be at any required voltage and frequency with the use of appropriate transformers, switching, and control circuits. A Solar Inverter changes DC voltage from batteries or solar panels, into standard household AC voltage so that it can be used by common tools and appliances. There are two types of solar inverter: off-grid inverter (stand-alone inverter) and grid tied inverter (grid connected inverter).

OFF-GRID INVERTER: Off-grid inverter or Stand-alone inverter is designed for remote stand-alone application or off-grid power system with battery backup where the inverter draws its DC power from batteries which is charged by PV array and converts it to AC power. Stand-alone inverters provide variety of size and output waveform depending on your applications. The pure sine wave inverter provides the best output suitable for solar home systems. This inverter is ideal for area where the utility grid is not available.

GRID-TIE IVERTER: Grid connected inverter or grid tie inverter is designed specifically for grid connected applications that does not requires a battery backup system. Grid connected inverter or grid tie inverter converts DC power produced by PV array to AC power to supply to the rated electrical needs and sell excess power back to utility grid.

With a wide range of sizes available, we provide off grid and grid tie inverter to suit any requirements, from small residential solar system to large commercial solar system.

Carisol have revolutionized the way people see inverters, providing silent, efficient and reliable AC electricity anytime, anywhere with a variety of sizes and power ranges to choose from, transforming DC electricity stored in batteries into standard electrical AC power.

The electrical inverter is a high-power electronic oscillator; an electrical device that converts direct current (DC) to alternating current (AC) the converted AC can be at any required voltage and frequency with the use of an appropriate transformer, switching and control circuits. It was so named because early mechanical AC to DC converters was made to work in reverse, and thus was “inverted” to convert DC to AC. There are two basic types of inverters that are commonly used to supply AC power from DC sources such as solar panels or batteries.

1. Modified sine wave inverter: The output of a modified sine wave inverter is similar to a square wave output except that the output goes to zero volts for a time before switching positive or negative; this is a simple, low cost device and is compatible with most non-sensitive electronic systems equipment. Most AC motors will run off this power source although at a reduction in efficiency of approximately 20%.

2. Pure sine wave inverter: A pure sine wave inverter produces an almost perfect sine wave output that is essentially the same as utility-supplied grid power making it compatible with all AC electronic systems. Its design is more complex, and costs more per unit power.
