Are what are you looking for in an off-grid Solar Inverter

Monday, February 10, 2014
The modern solar industry was through off-grid solar, a market born, remains an important aspect of the industry. Around the world one power of live six people out of reach, but they can rely on off-grid solar power systems. In North America the off-grid solar is especially popular for building in remote areas where the utility grid is not yet reached, or in places, the vulnerable to storms and power outages.

Off-grid solar systems are less common than grid-tie systems for a number of reasons. An off-grid system requires other components such as batteries and charge controllers. With additional components installation is more complex and requires a higher level of technical training. It is also more expensive for the end user, and not all end-user need solar off-grid.

Although grid more complex than grid tie and off-grid market continues to grow there is a shift with experienced installers are beginning to move from the competition-grid-tie market in the more lucrative grid market. Solar product suppliers also work to facilitate off-grid systems. Pay attention to the following offerings:

Off grid packages

Mains-independent system integrators can reduce the complexity of an off-grid system, by providing easy-to-install packages. A package can contain an inverter/charger, solar charge controllers, controls and accessories. The components should work all together, if you take them out of the box. A mains-independent ordering system, such as a package also ensures that all necessary parts are together and superfluous, plunge to contact the suppliers from a construction site to a forgotten part.

Flexible off-grid inverter

Another way, which is to reduce complexity of the off-grid solar projects to find a charger/inverter, the flexible enough to all installation requirements. Search for inverters with intelligent load management to handle a diverse set of energy loads. Load management is incredibly important if you connect your inverter to a generator or the utility network. Some inverters have dual AC input of the generator and the grid, which lowers the additional component system requirements and provides more flexibility for different system requirements take up. Connecting an off-grid solar system to the utility power grid (where possible) end user also gives you the opportunity to sell back excess energy to their energy supplier.

Stackable off-grid inverter

Creating an off-grid solar system requires a large up-front investment. It is common for homeowners with a smaller system, with plans to later add to start. Adding more is solar easy when you start with an inverter, which can be stacked together with other inverters. An existing grid tie solar-system it is an off-grid solar power inverter also increasingly by AC coupling. A grid-tie solar system is great, but it requires electricity to operate and turns any utility power outages. Off-grid inverter coupled with batteries only uninterruptible power supply will provide for critical loads.

Customer service

As mentioned previously, off-grid suited to solar systems for building remote sites. Remote sites require additional travel time to reach. Select to return visits to inverter, which have proven reliability and lasts for years. Trust suppliers who were successful financially in the broiler market for many years. Ask for references for older systems, or show you how to test the product internally.

If service is necessary, it is important that the supplier for the troubleshooting and enable quick resolution will be available. The supplier should reach the end user for emergencies. Troubleshooting enables new technology makes faster remote connections to the grid inverter. This can be done by a remote monitoring system. Search for systems that can upgrade firmware even from afar.

The off-grid solar market continues to grow, these offers will ensure that off-grid off-grid solar systems secure, reliable, and cost effective.

Listen here: emergency power supply and sustainable way of living off-grid

Tuesday, August 27, 2013
Hurricanes. Snow storms. Earthquake. Tornadoes. You have all clobbered populated areas in recent years, leading to extended power outages, fuel shortages, also the lack of drinking water. But people were living comfortably in completely off-grid, their own electricity produce, the use of sustainable sources of heat and even recycled water.

Have questions for Barry? Parts of you they can be answered in the comments and in the next episode.
These off-grid systems are and who sneaked into established America. Generators are sold in some supermarkets, wood stoves are popular heating, people learn how makes to recover and to reuse greywater and battery, which fuse are solar power systems through low-cost batteries combined with rising utility prices is rejuvenated. Inevitably, prices for these technologies more affordable will be more expensive as electricity, gas and water.

Our special guest for this week's show is death of DuBois, CEO of Sangha energy. Death company specializes in off-grid living systems including generators, battery backup solar power, grey water recovery systems. Tune in this week energy to renewable energy world show how death and Barry about your options for sustainable electricity, heat and water talk - also in your suburban jungle.
YOU will find click here to listen to the episode 5 of the energy show, and past events here.

About the energy show

We start as energy costs consume more and more of our hard-earned dollars, as a consumer really to make sure. But we need to us to accept $5 / gallon gas prices, $200 / month electricity bill and $500 heating costs. There are literally hundreds of products, tricks, and techniques that we can use to dramatically reduce these costs - very cost effective.

The energy show on renewable energy world is a weekly 20 minutes podcast, which offers to reduce tips and advice, your home and energy consumption. Each week we cover topics that help to lower your electricity bill explain new products and technologies in plain English, and through the hype cut so that you can make intelligent and cost-effective energy decisions.

About your host

Barry Cinnamon is a longtime supporter of renewable energy and a widely recognized solar power experts. In 2001 he founded Akeena solar - she grew to the largest national residential solar installer from the middle of the last decade with more than 10,000 roof customers coast to coast. He cooperates with Westinghouse to build Westinghouse solar in 2010, and sold the company in the year 2012.
His pioneering work to reduce costs on the rooftop solar power systems include Andalay, the first solar panel with built-in racking, earthing and cabling; the first UL listed AC solar panel; and the first fully "plug and play" AC solar panel. His current efforts focus on reducing soft costs for solar power systems, cause the system rates against double from Germany, in the United States.

Although Barry may be known for his outstanding work in the solar industry, he has hands-on experience with a variety of energy-saving technologies. He makes residential energy audits since the days of punch cards, developed one of the first ground source heat pumps in the early 80s and always adhere to the laws of thermodynamics.

Grid-tied and Off-grid Solar 101

Sunday, July 22, 2012
Will I need batteries for my solar system? How much does it cost to go completely off the grid?

These questions often come up as people start thinking about going solar. So, what does it really mean to go "off-grid" with a PV system? First, let's take a look at a traditional grid-tied system.

Grid-tied Solar

When most people install a solar electric system, it is connected to the utility grid, hence the name "grid-tied."

When your solar system is connected to the grid, you still have access to energy after dark without batteries. Your grid-tied system simply pulls the electricity you need from the utility grid.

A grid-tied system is simple. When the grid-tied system produces more energy than is being consumed, the excess electricity is sent to the grid, spinning your meter backwards as credit toward your next electricity bill. When the demand is higher than the energy being produced by the PV system, the home draws energy from the grid. This is called net metering.

Just think of the grid as your battery.

The benefits of grid-tie solar are net metering and a lower upfront cost than off-grid systems. One of the only down-sides to a grid-tied system is that you'll still experience blackouts when the power goes out in your neighborhood.

Why does my power go out even when I have a grid-tied solar system?

This is because your are connected to the utility grid. When there's a power outage, the power company often has to send out a maintenance team to fix the problem. If there is a live energy feed, this can be especially dangerous for the workers who are repairing power lines.

For most people, a power outage here and there isn't too much of a concern. Just keep your refrigerator closed for couple hours and if you want to make sure that you can charge your iPad, get a JOOS Orange Portable Solar Charger.

But what about Armageddon? Or the zombie apocalypse?! I'll need power to fight off the living dead!

If you live in an area that is plagued by frequent blackouts, hurricanes, or some other cause for concern such as the living dead chewing on power-lines, battery backup may be an option for you.

Keep in mind, battery backup is for critical loads, so you really can't blast the AC and leave the television running 24/7 in the aftermath of a natural disaster. In most cases, it will mean you can keep some lights on and a small refrigerator running. This combination of a grid-tied system with a backup battery supply for emergency situations is known as a hybrid solar system.

Going Off the Grid

An off-grid solar system, otherwise known as a stand-alone or autonomous solar system, is the kind of solar system you would install in a remote location that would not otherwise have access to usable grid energy. This includes isolated dwellings, boats, or RVs that use solar electricity.

If you are setting up an off-grid system for your boat or RV, there's a good chance you won't need an inverter because they are likely designed to run on direct current, or DC power. If you're using your off-grid system to power your home, you'll need an inverter to convert DC to AC, which is compatible with the appliances in your home (like grid electricity).

For off-grid systems, GoGreenSolar.com usually recommends the 3000-W Outback FX3048T or the 5000-W SMA Sunny Island 5048U Off-Grid Inverters.

The main benefit of an off-grid system is the sense of self-reliance that comes from knowing you don't rely on the power company for electricity.

Though the idea of going off the grid is appealing, for most consumers it is not a practical investment. The additional equipment that is required for an off-grid system means that your overall system will cost more upfront and incur additional maintenance.

Off-grid solar systems require a battery bank to store the solar energy that is collected by the array. Without a battery bank to store energy, it'll be lights out by sunset.

Since a battery can only hold a limited amount of energy, you can't depend on the excess energy produced during the summer to be around for those cloudy winter days.

Off-grid batteries will most likely need replacing in about seven years if you're using it correctly. If you are thinking of installing an off-grid solar system, please educate yourself so you have the know-how to maintain your system properly. We also ask that you please recycle your used batteries because they can be an environmental hazard.

When is it financially feasible to go off the grid?

Because of the additional costs associated with off-grid systems, it often makes little sense to go this route unless you live in an area where grid electricity is either too expensive or inaccessible.

Though the idea of going entirely off the grid is sexy, it just doesn't make sense for most people at this point in time. When superior battery technologies become available at affordable prices, off-grid solar may well become a viable option. Until then, if you can go with a grid-tied system, it's probably your best choice.
