Tsunami will hit Delta’s Q2 results
Delta Electronics (Thailand) has warned that its financial results will remain weak in the second quarter due to the impact of the Japanese tsunami after the largest SET-listed electronics firm reported a 38% drop in net profit in the first three months.

In this video, i show how i use my 12 volt inverter to lessen the load on my 48 volt inverter. This allows me to get more overall run time out of my current system. I use the Trace 5548 inverter for the larger demands we require in our day to day household energy usage. Questions and comments are always welcome. Enjoy !

renewablehome-energy.org Australia comprises an amazing and almost perfect climate for solar power supply. If you are in Australia, then it is easy to realize that generating solar power in Australia costs less than buying it from a utility company. Still, due to lack of proper knowledge, people like to keep themselves away from generating their own electricity. However, the rising cost has forced them to explore other viable options, and there could have been nothing better and cheaper than solar energy. Sources are in plenty, but only few match the precise needs for home solar power, and solar inverters among them. Photovoltaic technology gets used for creating electricity from solar power. The solar panels installed on the top of your roof comprise solar cells, which utilize photovoltaic technology to change direct sunlight into direct current (DC) electricity. Solar cell comprises silicon dioxide, which further reacts with photons and forces an electron to move in the silicon dioxide. And thatâ??s how the direct current is being created, and for the reason of a series arrangement among the cells, the flow of current gets from one to another cell. Direct current works fine to run more than a few home appliances

SMA Solar Technology AG develops, produces and sells solar inverters and monitoring systems for photovoltaic applications. SMA is the worlds largest producer in this segment and is the only vendor that has a product range with the matching inverter type for any module type and any power class. This applies for grid tied applications as well as island and backup operation. The inverter is technologically the most important component in any solar power system: it converts the direct current generated in photovoltaic cells into alternating current suitable for the grid. In addition, it is an intelligent system manager, responsible for yield monitoring and grid management. Solar inverters are characterized by a particularly high efficiency. The Sunny Mini Central produced by SMA already has an efficiency of over 98 %, which allows for increased electricity production. SMAs business model is driven by technological progress. Due to its flexible and scalable production, SMA is in a position to quickly respond to customer demands and promptly implement product innovations. This allows the Company to easily keep pace with the dynamic market trends of the photovoltaic industry and at the same time absorb short-term fluctuations in demand for solar inverters. SMA Solar Technology AG is headquartered in Niestetal, near Kassel, and is represented by sales and service subsidiaries on four continents in eleven countries. This group of companies employs more than 3000 employees (incl …

Solar inverters are extremely important in the conversion to solar energy, which is fairly easy to do. You can choose a solar kit or create your own kit. Many individuals believe solar panels are the single most important piece of working with solar energy, but this is not true. The parts required to collect solar energy are all integral and tightly work together.

Solar inverters convert the direct current (DC) that is collected from the sun’s rays into alternating current (AC), which is used with all household electronics.

There are several simple varieties of electrical inverters. In one of the simpler circuits, the DC power is connected to a transformer. A switch is then rapidly turned to allow current to flow back and forth to the DC source, which then follows two alternate paths through one end of the primary winding and then the other. This creates an alternating circuit.

There is also an electromechanical version of the switching device. Two stationary pieces work with a spring to provide support. The spring holds the contact against one of the stationary contacts. This allows the current to be interrupted by the movement of the switch, which creates vibrating as it moves back and forth. This alternates the current.

There are three basic types of solar inverters. Each is used for different types of solar energy, such as being on-grid or off-grid. Some include anti-islanding protection. All three can be easily removed and replaced, if your energy plans change.

Stand-alone inverters are used for isolated locations, such as boats, cabins, etc. This inverter draws the direct current energy from batteries and other sources such as wind turbines, hydro turbines, and engine generators. The stand-alone inverter often incorporates battery chargers which help to recharge the battery from the alternating current source. Stand-alone inverters are often off-grid, which means they don’t require anti-islanding protection.

Grid-tie inverters complement grid power energy with solar energy. The inverter ensures that the energy received from the solar collectors will phase in with the energy from the utility grid. This makes it possible to reverse the power and sell excess energy back to the utility company. Grid-tie inverters do not supply energy in the event of a power outage.

Battery backup inverters draw energy from a battery. They are capable of providing energy in the event of a power outage, and because of this they require anti-islanding protection.

Anti-islanding protection can be an important part of using a solar inverter. When there is a power outage with the utility company, the circuits sometimes still send out resonating currents, which solar inverters can confuse with regular currents. The inverter will continue to work because of this confusion, which can be dangerous for utility workers who believe the power to be off. Anti-islanding protection injects a pulse into the current that offsets the resonation. This will turn off the solar inverter.
