1.0 BASIC PRINCIPLE OF SOLAR INVERTER 

A solar inverter, or PV inverter, converts the variable direct current (DC) output of a 

photovoltaic (PV) solar panel into a utility frequency alternating current (AC) that can be fed into a commercial electrical grid or used by a local, off-grid electrical network. It is a critical component in a photovoltaic system, allowing the use of ordinary commercial appliances. Solar inverters have special functions adapted for use with photovoltaic arrays, including maximum power point tracking and anti-islanding protection 

1.1 NEED OF SOLAR INVERTER

There are two types of sources for electrical power generation. One is conventional and other is non- conventional. Today to generate most of electrical power conventional sources like coal, gas, nuclear power generators are used. Some of conventional source are polluted the environment to generate the electricity. And nuclear energy is not much preferable because of its harmful radiation effect on the mankind. After some of ten years conventional sources will 

not sufficient enough to fulfill the requirements of the mankind. So some of the electrical power should be generated by non-conventional energy sources like solar, wind .With the continuously reducing the cost of PV power generation and the further intensification of energy 

crisis, PV power generation technology obtains more and more application. 

Conventionally, there are two ways in which electrical power is transmitted. Direct current (DC) comes from a source of constant voltage and is suited to short-range or device level transmission. Alternating current (AC) power consists of a sinusoidal voltage source in which 

a continuously changing voltage (and current) can be used to employ magnetic components. Long distance electrical transmission favors AC power, since the voltage can be boosted easily with the use of transformers. By boosting the voltage, less current is needed to deliver a given 

amount of power to a load, reducing the resistive loss through conductors. 

The adoption of AC power has created a trend where most devices adapt AC power from an outlet into DC power for use by the device. However, AC power is not always available and the need for mobility and simplicity has given batteries an advantage in portable power. Thus, for portable AC power, inverters are needed. Inverters take a DC voltage from a battery or a solar panel as input, and convert it into an AC voltage output. 

1.2 TYPES OF SOLAR INVERTER

Solar inverters may be classified into three broad types. 

1. Stand Alone Inverters 

2. Grid Tie Inverters 

3. Battery Backup Inverters 

1.3 STAND ALONE INVERTERS 

Stand-alone inverters, used in isolated systems where the inverter draws its DC energy from batteries charged by photovoltaic arrays. Many stand-alone inverters also incorporate integral battery chargers to replenish the battery from an AC source, when available. Normally 

these do not interface in any way with the utility grid, and as such, are not required to have antiislanding protection. 

1.4 GRID TIE INVERTERS 

Grid-tie inverters, which match phase with a utility-supplied sine wave. Grid-tie inverters are designed to shut down automatically upon loss of utility supply, for safety reasons. They do not provide backup power during utility outages. 

1.5 BATTERY BACKUP INVERTERS 

Battery backup inverters, are special inverters which are designed to draw energy from a battery, manage the battery charge via an onboard charger, and export excess energy to the utility grid. These inverters are capable of supplying AC energy to selected loads during a utility 

outage, and are required to have anti-islanding protection.

Symtoms of corovirus

According to WHO media says

There are now more than half a million confirmed cases of COVID-19 and more than 20,000 deaths.

These are tragic numbers, but let's also remember that around the world, more than 100,000 people have recovered.

Yesterday, I had the honour of addressing an extraordinary meeting of leaders from the G20 countries.

My message was threefold: we must fight, unite and ignite.

Fight to stop the virus with every resource at our disposal;

Unite to confront the pandemic together. We are one humanity, with one, common enemy. No country can fight alone; we can only fight together.

And ignite the industrial might and innovation of the G20 to produce and distribute the tools needed to save lives.

We must also make a promise to future generations, saying never again.

Viral outbreaks are a fact of life. How much damage they do is something we can influence.

I thank the G20 countries for their commitment to fight the pandemic, safeguard the global economy, address international trade disruptions and enhance global cooperation.

This is especially important for countries who are not part of the G20 but will be affected by decisions made by G20 countries.

Earlier today, we held a briefing with around 50 Ministers of Health from around the world at which China, Japan, the Republic of Korea and Singapore shared their experiences and the lessons they have learned.

Several common themes emerged about what has worked:

The need for early detection and isolation of confirmed cases;

Identification, follow-up and quarantine of contacts;

The need to optimize care;

And the need to communicate to build trust and engage communities in the fight.

Countries also expressed several common challenges.

The chronic global shortage of personal protective equipment is now one of the most urgent threats to our collective ability to save lives. 

WHO has shipped almost 2 million individual items of protective gear to 74 countries that need it most, and we’re preparing to send a similar amount to a further 60 countries.

But much more is needed.

This problem can only be solved with international cooperation and international solidarity.

When health workers are at risk, we’re all at risk.

Health workers in low- and middle-income countries deserve the same protection as those in the wealthiest countries.

To support our call on all countries to conduct aggressive case-finding and testing, we’re also working urgently to massively increase the production and capacity for testing around the world.

One of the most important areas of international cooperation is research and development.

A vaccine is still at least 12 to 18 months away.

In the meantime, we recognize that there is an urgent need for therapeutics to treat patients and save lives.

Today we are delighted to announce that in Norway and Spain, the first patients will shortly be enrolled in the Solidarity Trial, which will compare the safety and effectiveness of four different drugs or drug combinations against COVID-19.

This is a historic trial which will dramatically cut the time needed to generate robust evidence about what drugs work.

More than 45 countries are contributing to the trial, and more have expressed interest. The more countries who join the trial, the faster we will have results.

In the meantime, we call on individuals and countries to refrain from using therapeutics that have not been demonstrated to be effective in the treatment of COVID-19.

The history of medicine is strewn with examples of drugs that worked on paper, or in a test tube, but didn't work in humans or were actually harmful.

During the most recent Ebola epidemic, for example, some medicines that were thought to be effective were found not to be as effective as other medicines when they were compared during a clinical trial.

We must follow the evidence. There are no short-cuts.

We also need to ensure that using unproven drugs does not create a shortage of those medicines to treat diseases for which they have proven effective.

As the pandemic evolves and more countries are affected, we are learning more and more lessons about what works and what doesn't.

WHO is continuing to support all countries in the response.

We’ve published more than 40 guidance documents on our website, providing detailed, evidence-based recommendations for governments, hospitals, health workers, members of the public and more. 

More than 1 million health workers have been trained through our courses on OpenWHO.org. We will continue to train more.

We’re also delighted to report that the COVID-19 Solidarity Fund has now received donations of more than US$ 108 million in just two weeks, from 203,000 individuals and organizations.

Thank you to each and every one of you.

The English version of our WhatsApp Health Alert now has more than 12 million users globally, and the Arabic, French and Spanish versions were launched today. More languages will be added, including Bangla, Chinese, Hindi, Kurdish, Portuguese, Russian, Somali, Urdu, Swahili and more.

I’ve said before that crises like this bring out the best and worst in humanity.

We have recently seen an increase in scams, cyberattacks and impersonation using WHO, my name and COVID-19.

I am very grateful to those working in various national organizations providing critical cybersecurity intelligence to the WHO Cybersecurity team.

Thank you for your efforts to work with us to protect the health systems, health workers and members of the general public who rely on our information systems and digital tools. Special thanks to Microsoft for assisting on this.

I’d like to end with something Singapore’s Minister of Health, Gan Kim Yong, said during today’s briefing.

We are only at the beginning of this fight.

We need to stay calm, stay united and work together.

I thank you.

ACCORDING TO NNN

The International Committee of the Red Cross (ICRC), says no fewer than 21,600 Nigerians got missing in 2019.

The ICRC Communication Field Officer in charge of Port Harcourt Delegation, Mrs Sophia Uduma, made the revelation in Enugu on Tuesday while speaking with newsmen.

Uduma said majority of the persons got missing during violence or communal wars, which according to her is prevalent in the Northern part of Nigeria.

The communication officer noted that the cases of persons reported missing were being handled by the ICRC in collaboration with the Nigerian Red Cross Society.

Uduma, however, maintained that 159 minors separated from their families were reunited with their family members while families of 886 missing persons received information about the whereabouts of their loved ones

“The International Committee of the Red Cross is a non-religious humanitarian organisation that works tirelessly to provide life saving assistance and sustained development initiative to affected populations,” she said.

On the mandate of the Committee, she emphasised that the organisation worked mostly during wars to assist victims of armed conflicts, encourage humane treatment of detainees, reunite separated family members and promote respect for international humanitarian law.

“In 2019, the ICRC assisted about three quarter of a million persons in Nigeria with food and household items while about 500 were supported to either establish or enhance streams of income to help them build sustainable livelihood,” Uduma said.

On the issue affecting operations, Uduma lamented that “the provision of humanitarian assistance increases threat to the lives of aid workers in the area where the ICRC previously gained access”.

“Humanitarian workers put their lives at risk to reach affected populations and must be respected and allowed to work unhindered if their labour is to have sustained impact,” she said
