BECOME ENERGY SELF-SUFFICIENT Living off the grid and being self-sufficient feels good. For some people, this feeling is worth more than saving money. Energy self-sufficiency is also a form of security. Power failures on the utility grid do not affect off-grid wind systems. On the flip side, batteries can only store a certain amount of energy, and during cloudy times, being connected to the grid is actually where the security is. You should install a backup generator to be prepared for these kinds of situations.

Because wind turbines are new energy products, they are vulnerable to external natural factors and cannot achieve full efficiency
Please connect the system according to our following requirements:
1. The installation height of the wind turbine shall be at least 10-15m, and there shall be no trees or buildings around.
2. The wind speed shall reach at least 10m/s.
3. The system voltage of storage battery, wind turbine and charging controller must be the same . And please check the state of the battery. The remaining power of the battery should be in the range of 10% - 90%. 
4. Connection method: (1) First connect the charging controller with the battery. The black wire is the negative pole, and the red wire is the positive pole. It cannot be reversed. (2)  then the other three blue cables of the charging controller can be connected with the three cables from the wind turbine.

ADVANTAGES OF OFF-GRID SOLAR SYSTEMS

1. NO ACCESS TO THE UTILITY GRID
Off-grid solar systems can be cheaper than extending power lines in certain remote areas.
Consider off-gird if you’re more than 100 yards from the grid. The costs of overhead transmission lines range from $174,000 per mile (for rural construction) to $11,000,000 per mile (for urban construction).

The mast is not included, we can give you the reference by the flange size, you can prepare the mast yourself

Also, the model has almost no friction (except for the inevitable smooth-running bearing) and also a lower magnetic resistance of the generated current during power build-up compared to other models, which works optimally due to an efficient vertical and horizontal wind utilization and little wing resistance area, which makes it very easy to start with low wind and runs for a very long time and is therefore particularly suitable for regions with less wind, which applies approximately to 98% of all regions and thus ultimately offers an efficient wind utilization over the year than a "supposedly" stronger 1000-3000W system. In terms of performance, comparable to the much more expensive SkyWind System 1000, but significantly quieter and much less demanding in construction and vibration. According to our test, the annual yield is probably even comparable to the two other exemplary wind turbine models "taken together" in both wind-weak and strong regions, at a medium price range. In addition, the generator is mounted above the bearing on the wind turbine, so its mass is then moved as swing weight when turning ,which leads to that when it is started at 1,3 m/s, even with low wind then very long runs so not only 3-4 turns like the EOLO 3000 does, or ca.8-20 like the Domo 1000 but mostly runs for hours (with me often 20-30% of the day), So as long as the wind also lies directly at the wind turbine, then really long runs evenly. In addition, it is even quieter than the many other models because there is no rattling of a bearing on the mast and also the wind wing design produces practically hardly any noise and is extremely quiet with <22dB at 8/ms and <45db at 20m/s (so basically no own or nuisance of the neighbors occurs, especially since the wind noise is practically higher) at a wind efficiency Use of high 70%. According to own calculations, the power value would come at 0.611 area and 62-70% efficiency and 10m/s sec to 350-700W, 12m/s 599-800W (which is usually taken as standard) and only reach 833W at 13-14m/s, so seen the power curve of the manufacturer seems a little optimistic, respectively. slightly postponed, but can be presented in practice even more positively differently by other factors, Conclusion: all in all, according to our research, a very mature Darriies Helix wind turbine and thus probably the best available model on the market of this favorable performance and price class with relatively space-saving model variant with effective wind utilization from all
