About US
  • The first thing to think about is how much power you need.Fortunately, sizing off-grid inverters is straightforward if you know what appliances you’re going to use.Add up the wattage of all your lights and appliances to calculate the number of watts you’d need if everything was used all at once. (No, you’re not likely going to use everything, but this is an easy way to be safe.)Don’t forget to consider the voltage—although most appliances run on 120Vac, some appliances, such as well pumps, require 240Vac. Example: Let’s say you need 1,000 watts for your fridge, 500 watts for lights, and 200 watts for your phone & TV. That adds up to 1,700 watts. In this case, we’d suggest a minimum inverter size of at least 2,000 watts to give you a little extra headroom. (After all, you may add appliances in the future.) Look at the Technical SpecsHere are some other technical specs to consider:Efficiency. This is a measure of how much power from the batteries your inverter delivers to your home when it’s operating in perfect conditions. A good peak efficiency rating is around 94% to 96%.Self-consumption, or no-load current draw. How much power will your inverter consume just sitting there? Obviously you want this to be as low as possible.Surge capacity. How much short-term overload can the inverter handle before it “trips?” Some appliances, like pumps or fridges, need as much as 2x–3x their running power to start up.Battery charger output. Many off-grid inverters include a battery charger, which is used to recharge your batteries during the winter months with a backup generator. The battery charger will have a rating, usually measured in amps. Most decent off-grid inverters will have a battery charger in the range of 50-100 amps DC.Temperature range. Inverters are sensitive to extreme heat. Pay careful attention to the temperature range if you plan on installing your system in your garage or anywhere it could be exposed to temperature extremes.Warranty. Warranties start at 1 year and typically range from 3-5 years, with a few manufacturers offering a 10 year warranty extension option.

  • A grid-tied inverter takes DC power from solar panels, turns it into AC, and sends it into the grid for credit.Grid-tied inverters are simpler and easier to wire since there are usually only two main components—the inverter itself and your solar panels. (Some grid-tied systems are starting to incorporate energy storage, but most don’t have any batteries at all.)But an off-grid inverter needs a battery bank to function.Here’s how it works: your solar panels feed DC power into the batteries. Then your inverter takes that power and “inverts” it, creating AC power for your home. This works essentially like a miniature power grid.(In case you’re curious, no, your inverter won’t deplete your batteries provided your system is set up and designed right. The battery bank gets recharged by your solar panels and a charge controller, and by a backup generator in the winter months.)As you might imagine, off-grid systems are more complicated, thanks to additional components like the charge controller, battery monitor, and additional AC and DC circuit breakers. All of these things tend to make off-grid systems more difficult to wire and install.It can also be a challenge to buy off-grid equipment because there are a lot of associated accessories: remote controls, battery monitor, breakers and enclosures, surge suppressors, and so on.Picking the right parts can be confusing enough—but there’s no more critical decision than buying the right inverter.

  • If you thought that solar lights come in one form and a couple of uses, you are not the only one. However, you should know that as technology evolved, solar lighting systems also evolved—with two main types.Solar lighting can be installed in different areas. From homes to parking lots, sensitive areas and remote locations where no grid infrastructure exists, it removes the costs of trenching and wiring which is why it is considered as the cheapest solution in numerous cases.The two main types of solar lights are:1. Outdoor solar lights2. Indoor solar lightsNow, the classification around solar LED lights can be branched out to even more types. Home lights, yard lights, street lights, solar-powered lights for parking lots and garden lights are just some of the examples.

  • Neoen plans to deploy a 30MW/30MWh battery storage system in Finland to help the country integrate its growing wind power capacity, foreign media reported.Neoen has partnered with Tesla to deploy the Hornsdale Battery Energy Storage project in South Australia, which is currently the largest lithium ion battery energy storage project in the world with a capacity of 150MW/ 193.5MWH. Neoen is developing France's largest solar power project to date, with a 300MW installed capacity called Cestas.Finland plans to achieve national carbon neutrality by 2035. Neoen says the battery storage system will help facilitate grid integration with renewable energy projects, improve the reliability of power systems and reduce the cost of grid operations. Neoen business director Christoph Desplats-Redier says partners including Fingrid and the city of Lapiranta helped Neoen launch the project.This is probably the largest battery storage system in the Nordic country to date. Other grid-scale energy storage projects in Europe have been reported in the industry press, such as Vattenfall's plans to develop a pilot 1MWh lithium-ion energy storage system, which will be operational in Sweden this year. Saft announced in November 2019 that it has acquired a 21MW/ 6.6MWH battery energy storage project deployed by Finnish wind power developer and operator TuuliWatti; Fortum, another Finnish energy developer, said in 2018 that it would deploy a 6.2MWH battery storage system at its hydro power facility in Sweden.
