ADVANTAGES OF GRID-TIED SYSTEMS

1. SAVE MORE MONEY WITH NET METERING
A grid-connection will allow you to save more money with wind generator through better efficiency rates, net metering, plus lower equipment and installation costs:
).Batteries, and other stand-alone equipment, are required for a fully functional off-grid wind system and add to costs as well as maintenance. Grid-tied wind systems are therefore generally cheaper and simpler to install.
).Your wind turbine generator will often generate more electricity than what you are capable of consuming. With net metering, homeowners can put this excess electricity onto the utility grid instead of storing it themselves with batteries.
).Net metering (or feed-in tariff schemes in some countries) play an important role in how wind power is incentivized. Without it,residential wind systems would be much less feasible from a financial point of view.
).Many utility companies are committed to buying electricity from homeowners at the same rate as they sell it themselves.

2. THE UTILITY GRID IS A VIRTUAL BATTERY
).Electricity has to be spent in real time. However, it can be temporarily stored as other forms of energy (e.g. chemical energy in batteries). Energy storage typically comes with significant losses.
).The electric power grid is in many ways also a battery, without the need for maintenance or replacements, and with much better efficiency rates. In other words, more electricity (and more money) goes to waste with conventional battery systems.
).According to EIA data[1], national, annual electricity transmission and distribution losses average about 7% of the electricity that is transmitted in the United States. Lead-acid batteries, which are commonly used with solar panels, are only 80-90% efficient at storing energy, and their performance degrades with time.
).Additional perks of being grid-tied include access to backup power from the utility grid (in case your solar system stop generating electricity for one reason or another). At the same time you help to mitigate the utility company`s peak load. As a result, the efficiency of our electrical system as a whole goes up.

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).

2. 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.

Please according to our following requirements:
1. The installation height of the wind turbine shall be at least 10m, and there shall be no trees or buildings around. Of course, the higher the mast, the better the wind turbine can utilize wind energy and achieve the best results.
2. If the wind speed is only 3-5 meters/s, the wind turbine can only maintain rotation, and the power generation effect may not achieve the expected effect. The actual local wind speed needs to reach at least 10 meters/s to achieve the expected effect. The higher the wind speed, the better the wind power generation effect.
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%. It cannot be a state of fullness.
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.
