UNplug solar controller aims to refrain from you take your fridge off the grid - Treehugger
Where's the mesial ground between having a small solar charger for your gadgets, and having a rooftop solar array capable of powering your entire house. Solar energy is like a bat out of hell becoming a viable option for many homes and businesses, and every week seems to bring news of another new solar financing instrument or a drop in prices, but it's still out of reach of many of us, just in terms of the initial... I'd love to put solar on my house, but I'm not in a position just yet to make that financial commitment. However, I do have a few solar chargers and gadgets that be available for me well for charging small devices at home or in the woods, but they aren't nearly big enough for the task of powering even some of my household needs. I've often pondered the doctrine of building a small standalone solar energy system that can provide clean electricity for at least some of my home's needs, that wouldn't hire a major investment, and that could essentially be a small step toward... And I know I'm not the only one, because the internet is full of plans and articles and forums for edifice your own DIY solar system, so it's clearly an idea whose time has come. Most of those plans, however, are often intended for off-grid and remote applications, and not integrating into an for the most part grid-tied house, which is where so many of us could really use it. But a new crowdfunding campaign for a device that aims to... The UNplug solar controller was invented by Markus Löffler in retort to his own power blackout experience, where several days without electricity meant a lot of spoiled food. Löffler , an entrepreneur and software engineer living in Altadena, California, developed the UNplug whim to serve as a simple and inexpensive way to begin going solar, because it serves as the brain of a micro-solar system, starting as small as... By using the greenest vivacity source there is… solar. No moving parts, the power is just absorbed through solar panels. With this free energy, you turn your power needs “off the grid” during the most deprecating "peak" times in a day. At night UNplug automatically switches you back to the electricity grid. During the day, UNplug feeds electricity from the solar panel into the appliances connected to it, and charges the battery bank, and then when the sun goes down, it seamlessly switches over those devices to using grid power. In the consequence of a blackout, UNplug then powers those same appliances from the battery bank, allowing certain crucial electricity needs to continue to be met during an outage. The UNplug could put aside homes to take at least some of their daily electrical loads off the grid, such as the fridge or other household devices, while also serving as an uninterruptible power supply (UPS) in the outcome of a power outage. The device doesn't function all by itself, of course, and requires solar panels, batteries, an inverter, and other accessories, but according to Löffler's competition page, a small system could be set up for an additional $570 or so, on top of the...

Selecting Power Supplies for Peak Weight Applications - Power Electronics Technology
Specifying an ac-dc power provisioning for systems with peak load requirements that are higher than the normal power requirements for short periods can result in larger, higher-power, and higher-fetch product selection. In these applications, the average power required is typically significantly lower than the peak demand and, with care, savings in artefact size and cost can be realized without compromising system reliability or lifetime. Using a power supply that is capable of supporting the peak anxiety but with a lower continuous power rating will result in a physically smaller power supply reducing system size, moment, and cost. For example, in a system that requires 300W for a short duration, using a 200W continuously rated power supply that can encouragement a 300W+ peak load will result in significant savings in volume and cost over a supply rated at 300W continuous output... These products have unexceptional power demands far lower than the peak power requirements and are found in factory automation, medical devices, fluid and material handling, robotics, power tools, machining, packaging, assay, dispensing systems, and... A power supply is rated for up to 30 seconds with a duty cycle of 10 to 15% at a hill load that is just below the overcurrent protection (OCP) limit. There are applications where an additional 20-30% of power is required for short durations. These are typically electromechanical applications that want higher peak current for a shorter duration. Taking advantage of these characteristics to support occasional peak power demands results in a smaller, diminish cost supply, but the average power demand must be kept below the maximum continuous rating. Typically, this allows peak prevailing handling for 200-500 μs. This type of peak capability covers a limited range of applications. A higher power rating at record-line, normally meaning 180 VAC and above. For example, a 1200W power supply may be able to provide 1500W of persistent power when operated at an ac input voltage greater than 180 VAC. This is a genuine size and cost benefit if the ac input is in the high-parade range and is ideal for higher power systems connected from phase to phase when the nominal single phase supply is low. A power delivery with the topology and thermal characteristics, designed to support high peak electromechanical loads. Such units may deliver up to twice their soi-disant power for 10 seconds or more with duty cycles up to 35% for demanding electromechanical applications in industrial process control. XP’s fleXPower modular power way is one example that allows several standard outputs alongside one that provides a high peak current. Often overlooked when considering perfection load applications are power supplies with a convection rating and a higher fan cooled rating. It is not uncommon for such a supply to be rated at up to 50% higher power when fan cooled compared to a not unexpectedly cooled environment. These products are generally of open frame or U channel construction and cover power ranges up to 500-600W. Such products are by character electrically. Source: powerelectronics.com
How to get off the Eskom grid - Unrestricted Online
Most people fantasize of load shedding as an annoying, but limited period (two-and-a-half hours in the Western Cape, four to six hours in Gauteng … mayhap eight hours in the municipalities that owe Eskom billions) during which they cannot watch... But it goes a lot further than that: load shedding also compromises our safety (see “Safety and protection”, below) and costs us a lot of money as we scrabble to protect ourselves from its more painful effects. At the time of writing in May 2015, Eskom was awaiting feedback from the Public Energy Regulator (Nersa) on its urgent application to increase the electricity tariff by 25. 3 percent for the 2015/16 financial year. The urge, says the power utility, is that it needs to recover the huge (R32. 9-billion) cost of open-cycle gas turbines, advantage a further R19. 9 billion for its Short-Term Power Purchase Programme. Nersa says it is considering the application, taking into account Eskom’s operational and fiscal challenges and the urgent need to stabilise South Africa’s electricity network to avoid a possible total blackout. So where does this give up us. There are many options, some of them relying on common sense (cutting down your electricity usage wherever possible) and others requiring a sound upfront investment – and here we could be talking anything from a... Committing to this kind of money requires a big leap of faith, but consider the possibility: if Eskom indeed escalates its tariffs as expected and the trend continues, you could be looking at a monthly bill several times larger than your give out one. If you run a household equipped with all the mod cons, this could equate to several thousand rands more than you’re paying now. Against that, extending your mortgage bond to finance a sustainable power induction may be a bargain. If you are cautious by nature, you might prefer to dip your toes in the water by going partly off the grid. However, if you’re thoroughly sick of disruptions and strongly resent your ever-increasing electricity bills, you’ll be among a relative handful of people looking to go off the grid permanently. Determining the most pertinent load-shedding survival strategy for your household comes down to a mixture of price (how much you are willing to pay for energy independence), convenience (some systems are fully automated, others press for constant... You may be content to stay with Eskom, seeking only to reduce the impact of regular blackouts. In essence, these are the options: an array of solar photovoltaic (PV) panels, roof- or mast-mounted gust turbines, a generator powered by petrol, diesel or LPG (liquid petroleum gas), battery packs of varying capacities, or a combination of these... Devotees of solar dynamism say this option makes more sense than ever because new technologies, economies of scale and other factors have reduced the price of PV panels to the point where it is affordable even to those with a humble income. com), a Pretoria-based company that offers energy solutions on both a domestic and an industrial scale, if solar is your preferred route, you have distinct options, from grid-tied to grid-interactive (or hybrid) to fully stand-alone. The simplest system consists of solar panels and a steer unit that ties into the national power grid. It feeds power to your home from the solar panels and from the grid. Source: www.iol.co.za
