off grid 48vdc 2kw inverter
Solar Power Inverter
The solar inverter is a critical component in a solar energy system. It 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. Typically, communications capability is included so users can monitor the inverter and report on power and operating conditions, provide firmware updates and control the inverter grid connection. Depending on the grid infrastructure wired …
GRID-CONNECTED WIND TURBINE SYSTEMS
For many years now small-scale domestic and commercial WIND TURBINE grid connected systems have proven themselves to be increasingly viable means of generating clean electricity AND providing a steady income.
After much negotiating with both DTI and electricity distribution companies during the last few years it has been agreed that turbines up to 6KW can be very easily connected to the grid to export electricity and receive an income. The (hard fought for) G83 recommendation gives anyone permission (hassle free) to …
… range as utility power! Skystream’s innovative downwind tail-less design and utility compatible inverter create an easy to install, low maintenance power system capable of producing an estimated 100 kWh/month of power with an average 7.9mph wind speed.
The Skystream’s unique design makes it one of the quietest residential turbines available, with a sound profile very similar to the background noise level in tests. The turbine can be mounted on 33 and 45 foot monopole towers for the least visually obstructive installation in suburban areas, or on taller guyed pole towers to increase system output.
The available wireless remote allows you to control the …
Off-Grid Systems will provide all the power you use and store energy in batteries, with no connection to the utility. Ideal for cabins, remote sites, or for those who just do not want to rely on the utility to provide their power. A home solar system typically consists of solar panels, a back-up battery, a charge controller, wiring and support structure. (The photos below illustrate a variety of applications.)
Stand-alone PV systems are often best in places where utility-generated power is either unavailable, undesirable, or too costly to hook up to. …

GE’s first time appearance at the Consumer Electronics Show in Las Vegas centers on smart grid technologies that will anchor the “connected homes” of the future – from efficiently using power to making it.
And on that power generation side is Southwest Windpower’s Skystream 600, which is making its own CES debut. The company, which is the world’s largest supplier of small wind systems, has residential-scale turbines already spinning everywhere from rural Kenya to the
America’s electric power grid is subject to immense inefficiencies that arise from the interplay between centralized power generation, local power consumption and on demand utility service. To put things into a broad perspective, the nameplate capacity of U.S. generating facilities is about 1 million Megawatts (MW), so if all of our power plants ran 24/7 we would have a theoretical annual generating capacity of 8.7 billion Megawatt-hours (MWh). Since demand for electricity fluctuates on both a daily and seasonal basis, total
… our knowledge, no other utility-sponsored green power program in America has ever offered anything close to such a long-term fixed green power charge.
Now, rising and unpredictable transmission congestion cost on the ERCOT grid (the amount of wind capacity in West Texas doubled in one year to more than 8,000 megawatts), has increased the cost of the latest batch of wind power and also makes it difficult to pinpoint a price that can stay fixed for 10 years, the life of the current wind contract.
However, if Batch six is not fully sold to individual subscribers, it will do little to raise electric rates in Austin. Green power is …
Google joins $5 billion U.S. offshore wind grid project
By Scott Malone
BOSTON | Tue Oct 12, 2010 1:30pm EDT
BOSTON (Reuters) – Google Inc has thrown its financial clout behind an ambitious $5 billion proposed electric transmission line intended to spark investment in new wind farms off the heavily populated U.S. East Coast.
The move, which is a gamble as no offshore wind installations have yet been built in the United States, marks the Internet search giant’s latest move away from its core business, joining investments in solar energy and a plan to develop a car that …
… need to be made this year in order to deliver low carbon energy for the UK according to National Grid chief executive, Steve Holliday FREng.
Speaking to a packed theatre as a guest lecturer at The Royal Academy of Engineering on 1 March, Holliday warned that the UK faces a pivotal year as decisions loom on replacing critical assets, many of which are now 50 years old, with new infrastructure that will enable the UK to cut carbon dioxide levels by a third ahead of the 2020 deadline.
He said: “We cannot underestimate the scale of the engineering challenge that will be needed to deliver a sustainable energy future—one which I believe is going …
