Integrated Photovoltaic Power Management System (IPPMS): A grid tied solar power controller combined with IPS technology

In this research an Integrated Photovoltaic Power Management System (IPPMS) has been designed to support the continuous power flow at household by integrating Instant Power Supply (IPS) and solar PV, which will also ensure the surplus electrical power to flow to grid. In this system, if solar power is available and loads are active, then power is supplied from solar to load but when the battery is not fully charged then power is supplied to the battery as well as loads from solar panels. During the unavailability of solar energy, and when the battery is not fully charged, then loads and battery collect power from the grid. Additionally, the generated excess electricity from solar panel can be served to grid at no load and fully charged battery condition. However, the analysis of the IPPMS shows that it costs lower than the grid electricity over a long run (5+ year period).
