Sun Spark inverter is photovoltaic inverter company. Which help to reduce electricity crises in Pakistan. According to a research it helps to decreases 20-30% crises. In this topology we use photovoltaic cells to get energy from the sun and store this energy in the DC batteries and the convert this DC source in to suitable energy (i.e. AC source). Because we use AC source in our home appliances, in industries, commercial and in domestic appliances. In this topology we use power components for converting DC voltage into AC voltage with the help of microcontroller to give pulses according to the circuit pattern
