ABSTRACT

This project involves the installation and maintenance of a solar-powered 6kVA inverter. The variable direct current (DC) output of a photovoltaic (PV) solar panel is converted into a utility frequency alternating current (AC) that can be supplied into a commercial electrical grid or used by a local, off-grid electrical network using a solar power inverter. It is an important part of a solar system since it allows standard AC-powered equipment to be used.
The assembling of this device was done by gathering all the required components required such as solar inverter, solar panel, charge controller, rechargeable battery. After making provision for all these components that they were assembled according to the wiring diagram.
The device was completely coupled, the result during the test shows that the solar inverter was able to respond to its operation by supplying 220vac output which can be used to power appliances.
At the end of this project – 6kva solar inverter, it was seen that the device is very much useful mostly in solving the power supply problem in our society.
In this work, the methods for proper installation and maintenance of a 6kva solar inverter will be discussed in detail.

Key words: Inverter, Solar module/PV, battery, charge controller and assembly

CHAPTER ONE

INTRODUCTION

1.1 BACKGROUND OF THE STUDY
Inverter integrated with solar energy performs the conversion of the variable DC output of the Photovoltaic (PV) module(s) into a clean sinusoidal 50 or 60 Hz AC current that is then applied directly to the commercial electrical grid or to a local, off-grid electrical network. In an inverter with solar energy, solar cell (also called photovoltaic cell) converts the energy of sunlight directly into electricity through the photovoltaic effect (Querikiol et al, 2018). A Photovoltaic (PV) module is an assembly of cells in series or parallel to increase voltage and/or current. A Panel is an assembly of modules on a structure. An Array is an assembly of panels at a site. Typically, communication support scheme is included so users can monitor the inverter and report on power and operating conditions, provide firmware updates and control the inverter grid connection (Santos et al, 2018).
The inverter inverts the DC voltage generated by the solar module into AC. The inverter performs the control loops necessary for all the power management functions necessary including DC/DC and DC/AC. The controller also maximizes the power output from the PV through complex algorithms called maximum power point tracking (MPPT). The PV maximum output power is dependent on the operating conditions and varies from moment to moment due to temperature, shading, cloud cover, and time of day so adjusting for this maximum power point is a continuous process.
This work is aimed assembling and maintaining a 6KVA inverter with solar energy.

1.2 PROBLEM STATEMENT
If there is one factor that has perpetually maintained the status of Nigeria as a developing country, it is its electricity sector. Till date, many households and industrial businesses cannot be guaranteed of 24 hours supply of electricity from the National grid. At this stage of Nigeria’s social and economic development, the country cannot deliver sufficient energy to the citizens despite huge financial resources that have been expended in the sector.
Rather, Nigerians have continued to rely on electricity generators for their power supply, fuel marketers are taking significant portion of households’ institutions of learning’ and businesses’ incomes to supply power, noise pollution from regular humming generators have become integral part of living for many Nigerians with imaginable consequences on their health. Because of these problems, there is a need to assemble of inverter with solar energy, to complement or augment the electricity supply from the National grid, reduce cost of energy consumed and eliminate noise/environmental pollution that is associated with running of generator.

1.3 AIM AND OBJECTIVE OF THE STUDY

The aim of this project is to assemble and maintain a 6KVA inverter with solar energy.
The objectives are as follows: -

To produce a gadget that can take a dc input from a solar panel and convert it to a 220vac output that can be used to power an ac appliance with a 6kva output and a 50Hz frequency.
To provide efficiency, steadiness in the use of power appliances, by ensuring continuous availability of power supply in the cause of main outage during an execution of an important or urgent assignment. Thereby enabling consumers to meet up with its office duties even when central power is not available.
Reduce load on the National grid that turn to be reduce the overall energy consumption dependency on the main energy supply in the country
Decrease customer utility bill on energy utilization because of its non-fuel consumption, low price and maintenance cost as compared to the convectional sources of power supplies within International and Local market.
Again, reduce carbon discharges and subsequently reduce global warming particularly in a period when poor climatic change has become a threat to human survival and life in general to all living creatures hence an ever increasing concern to control it.

1.4 Scope of Study
The scope of this work focused on assembling and maintaining a 6kva inverter with solar energy. solar power source makes it possible to provide a clean reliable and quality supply of alternative electricity free of surges or sags which could be found in the line voltage frequency (50Hz).

1.5 Significance of the Project
Carrying out this research will go a long way solving power supply problem in our country. This research work will throw more light on the best techniques for assembling and maintaining an inverter with solar energy. This study will also be designed to be of immense benefit to all the users of solar inverter most especially in industries.
Furthermore, as a consumer, this device will serve as a means of generating his or her own electricity they also will benefit from a reduction in their electricity bills.
Finally, going deep into this work will provide a means of employment to the student involved thereafter making him or her self-employed.
