Home Power Optimization: the REbus™Microgrid

Home Power: Meet the REbus™ microgrid!

Run your decentralized Renewables efficiently and put them to use flexibly. From solar PV generation to micro wind turbines and battery storage, include even electrical vehicle charging and integration!

A REbus™ microgrid is a flexible energy network operating alongside the existing AC distribution network. Click for some specs and details. REbus™ is the ideal standard for connecting different sources of clean energy, including solar modules and small wind turbines, into an integrated hybrid system. The REbus™ standard makes it possible to more efficiently store clean energy produced on-site, and is ideal for charging electric vehicles quickly. The performance of each product on a REbus™ microgrid is easily monitored through a built-in communication layer.

The REbus™ DC microgrid is a great solution for anyone looking to generate clean renewable energy whether on-grid or off-grid. It easily and efficiently integrates PV, wind and other alternative energy sources, allowing a single inexpensive inverter to connect to the utility grid. The communications link gives renewable energy consumers instant access to data from each of their renewable energy devices for monitoring or diagnosis.

Converting the power coming from your renewable energy source to a REbus™ microgrid is significantly more efficient than the same conversion to a convential AC grid. Plus, the high voltage DC transmission means lower current in the connecting wires which improves the power transfer efficiency.

Because of the reduced electrical current in the wires, the cost of wiring is reduced.

The integrated power line carrier communication scheme eliminates the need for expensive and unreliable wireless communications. In todays insanely wireless world, it is a good idea to use wired communications instead of Wi-Fi. Wired communications provide increase security, less EMF radiation and less exposure of humans, decreasing adverse health effects of EMFs. Optional Ethernet communications are also available.

The overall efficiency and flexibility of the REbus™ microgrid system is significant, reducing cost of de-centralized Renewables generation and further increasing acceptability and potential of these technologies by improved usability.

Airdolphin Well-Known Small Wind Turbine Brand Name

Due to extensive media coverage, Airdolphin has become something like a flagship Mini Wind Turbine and the darling of worldwide audiences. Despite the relatively high price per Watt installed and the rather steep $6000 to $6500 price tag usually attached to them by American vendors, there is tremendous interest in these two high-tech mini wind turbine models. After all, Airdolphin small wind turbines can still be cheaper and more efficient than solar PV, and the high-quality craftsmanship invested into Airdolphin small wind turbines on the manufacturer’s part and the resulting durability will go a long way in justifying the upfront cost.

Rated Wind-Speed of Mini Wind Turbines: Asian Manufacturers’ Dirty Little Trick

Small wind turbine classification is somewhat blurred due to the fact that some manufacturers have been pushing to rate their turbines at a very high wind speed of 12 m/sec instead of the usual lower 8 m/sec. As this might give their turbines a less impressive image, resorting to that artificially high (and both unprofessional and rather sleazy) 12 m/sec “standard” is increasingly used in the marketplace by Asian manufacturers to trick buyers into believing that their products are more powerful than they truly are. This will lead to disappointment and dissatisfied customers in the long run. It might even give Mini Wind Power a bad name in general over traditionally less-economical Solar Energy photovoltaic technology and re-infuriate that quite unreasonable “holy war” between Home Wind Power and Solar Energy.

On top, that “little trick” from Asia is nothing more than unfair competition, confusing customers and, as a result, making many of them arrive at a wrong buying decision. Certainly for the advantage of cheap (but, at closer scrutiny, not-so-powerful Chinese, and sometimes Japanese) wind turbine models.

Many British, European and U. S. manufacturers’ adherance to that solid 8 m/sec rule is therefore very commendable. Ratings at different (higher) wind speeds can then be provided separately for easier comparison and debunking those Asian over-clocked “ratings”.

Home Power as a Business: Using Renewables for Hedging Yourself Against Two Major Risks

Home power may very well save you during the upcoming economic downturn. It’s a bit like owning precious metals or “opting out” of our over-networked way of life in other ways. The beauty of investing in residential-scale Green Energy is its capability of hedging against two of the most likely economic risks threatening your money today: overall currency instability and consumer price inflation. These might materialize as soon as the end of summer 2012 and would likely be visible as a slight — and then accelerating — downturn and an increase in prices including energy and utility bills at one go. The supporting fundamentals for both are in place, it’s just a matter of time for them to materialize. As noted above, both are likely to happen rather soon (and yes, even though it may sound contradictory from a conventional economic point of view to have both a severe recession or even deflation and an increase in energy prices at roughly the same time, this is still a very likely scenario).

Why Mini Wind?

WIND is created by ineven heating of the surface of the earth. Wind turbines harness the kinetic energy in the wind and convert it into electrical energy. This energy can be used to power your home and work facilities.


Wind is an abundant and naturally occurring resource. Wind energy is one of the cleanest ways to produce electricty. Very little processing needs to be done to convert it into free and clean energy. Operation of a wind turbines produces no pollution with no emissions, exessive noise or waste heat by-product. Particularly with mini wind generators lacking most of the detrimental effects of large-scale wind farms, wind can be harvested with minimal impact on the environment, a very important factor in meeting our increasing energy needs. Mini wind systems can be deployed for distributed generation (right where the power is consumed) and thus save on wasteful transmission (there is up to 50% loss of energy in the grid alone) as well as prevent visual impact and EMF radiation from grid lines.


Wind is an inexhaustible resource. Operation and maintenance expenses can easily be forecast; especially with high-quality turbine systems designed to operate with no scheduled maintenance. Robust design and an expected life of 25 to 30 years provide added economic feasibility.


You will enjoy economic as well as environmental benefits from wind energy. Home Wind installations contribute energy and make cost savings possible for owners by offsetting power requirements from the grid. It is the most cost efficient way to produce electricity on your own, and with government incentives and rebates, the payback period on a mini wind system can be as little as nine years in some locations.

Ready-Made Accessory Kits for Your Wind Turbine

At, we are paying attention to detail: as buyers sometimes find it difficult to get the right accessories (large-diameter DC cabling, DPDT switches that can take sufficient current, fuses & more), we have come up with several turn-key sets for our most popular mini wind turbines. Click the links for micro inverters, fuses, high-current DPDT switches or larger-diameter cables and more.

Atlantic Canada: The Nova Scotia “ComFIT”

The highest mini wind FIT in the world is offered by the Canadian province of Nova Scotia since September 19th, 2011, but with a twist: the province has skipped solar energy altogether (not just PV but even highly efficient solar thermal and CSP) which has rightly been called ‘outright criminal’ by a local Halifax, NS newspaper; also, the ‘ComFIT’ scheme is limited to community projects only and thus excludes mainstream participants. It seems the province tried to make an ‘impressive program as cheap as possible’ and that some learning is still required in Nova Scotia. We do hope that current flaws are not permanent and that improvements will follow soon.

The Nova Scotia ComFIT appears to be a work in progress anyway with numerous updates and revamps being made already. Initially, the small wind band was even higher (at Can$0.66 per KWh) and has already been significantly reduced. We hope that reasonable additions will include an attractive FIT rate for solar technologies too and would like to stress that, although being less famous for their sunshine than Nova Scotia itself, even the U. K does have solar incentives including a very promising solar thermal FIT equivalent of 18p per KWh.

Web Frontend Upgraded

The website has been upgraded to provide significantly better response times even during higher-volume traffic. With new — and despite higher CPU clock speeds and overall better specs even more energy-efficient — hardware, we have addressed past performance issues and hope to provide a better user experience for everyopne interested in Mini Wind & Solar Technologies.

Using Home Power for Hedging Yourself in Two Ways

The beauty of a play in residential-scale Green Energy is its capability of hedging against both a general economic downturn and an increase in electricity prices at one go. Both are likely to happen rather soon (and yes, even though it may sound contradictory from a conventional economic point of view to have both a severe recession or even deflation and an increase in energy prices at roughly the same time, this is still a very likely scenario). The supporting fundamentals for both are in place, it’s just a matter of time for them to materialize.

Comparison HAWT and double helix-style designs

Q: Could you kindly give a comparison of your system to the double helix system of home wind power generators. I have been hoping to find a system that combines art, color, wild life protection and good efficient engineering design in one package. (submitted by Adelle Jang)

A: The system you mention seems to be a Vertical Axis system. We only have one very small VAWT among our offerings (50 W rated capacity). Reason: VAWT are still mostly in an experimental stage, many horzaontal modesl are already… tested and …proven. Among them this (“Airdolphin” — frankly, our least-favored one in some aspects, because it’s actually VERY efficient engineering, on one hand, comes at a HEFTY MANUFACTURER LIST PRICE on the other)!

Wildlife protection is, actually, not much different between VAWTs and HAWTs: even a small horzontal (propeller-style) turbine is (a) seen by birds and (b) heard by birds and bats and can therfore be avoided. Existing residual casualties among them DO also occur with windows, cars etc, and such residual fatalities cannot be avoided anyway. (Cars and conventional power etc poses a far more significant risk to bird and bat populations than a small turbine when the IMMEDIATE shift toward Green energy is done in due course and not postponed till the point where climate change severely affects animals, plants, and all of us.) Geese have been killed in the LaGuardia/Hudson river plane accident too, but aircraft are still not outlawed.Though I admit that I wouldn’t want to die in a trubine (of any design) the way some animals continue to do, that “wildlife argument” is sort of counter-productive when bearing the big picture in mind, for it means humanity would continue on that rotten energy path of coal, nuclear and oil which has to be left RIGHT NOW.

Art & color are also incorporated into “Airdolphin” with different colors available as a premium feature, see

I apologize for only comparing every of your points (above) to that Airdolphin model. I did this because it comes closest to most of the issues you raised. I am, actually, not overly into only touting our own products and would rather consider a broader approach but I, obviously, do not have so many details at hand for some other products I, quite hoestly, don’t know the first thing about — and it would be dishonest of me to pretend otherwise. We do, however, offer a broader view of thing on where we publish a selection of wider news on the subject (whether or not the items are offered at this time or not). You may want to have a look there, too. We are trying to sell products, but we do so because we are also idealists and enthusiastic about the opportunities for (necessary) change available on this basis.

We are very much in favor of helix-style systems and VAWT in general and we are already working on that subject in order to come up with a feasible VAWT solution in the future. As this may take some time (1.5+ years at the very least), we recommend going for existing models for the time being.

Also, incentives programs (tax breaks, government subsidies or even FITs) are available NOW, and as always with fiscal programs, they can be chnaged anytime, even retrospectively (this would even be constitutional in the fiscal policy field)! So this might be a further incentive of ‘taking the money and run’ (and also let your own system run) as soon as possible — on top of the actual benefit of avoiding new carbon emmissions today and not tomorrow.
