1) 1 PC Controller
2) 1 PC Dump load
3) 1 Set Installation screws
4) 1 PC User Manual
◆ The product is manufactured according the JB/T6939.1-2004 industrial standard andGB/T 19115.1-2003 national standard also with users’
◆ Big LCD display.The images tell working state visually.Various data show: real-time wind turbine voltage,current,power;solar panel
oltage,current,power;battery group voltage, charge current.(The main board is with button battery,in case of power failure, historydata can
besaved for 30 days)
◆ Two sets of control system,PWM constant voltage system and three-phase dump load system.
◆ PWM constant voltage control is 120% of the rated power of the wind turbine. In case exceeding of PWM’s capacity, the three-phase dump
load will automatically start immediately to ensure safe running of the overall wind turbine system.
◆ When the strong or super-strong wind conditions PWM control to ensure battery charged by the wind turbine with constant voltage and cur
◆ When the battery disconnect or damage, the three-phase dump load will start automatically to avoid the wind turbine idling and runaway
◆ The protection function of battery: polarity reverse protection, disconnection and damage protection.
◆ Over-charging protection of the battery: When the battery is full (the battery voltage getting 125% of the rated voltage), the controller will
carry out three-phase dump load automatically to stop charging the battery.
◆ Auto recharging of battery: When the battery voltage reduces to 108% of the rated voltage,it stops three-phase dump load to re
charge battery automatically.
◆ The controller is equipped with manual three-phase dump load switch. To using this switch, the wind turbine will carry out three-phase dump
◆ The inside of the controller is equipped with surge arrester. Contain the over voltage into the wind turbine under the bearable voltage of the
equipment or system. On the other way, to conduct the strong lightening current into the earth directly to avoid any damage of equipment.
※ Solar panel control system is optional.Based on customers’ requirement.
※ Disel generator port is optional.Control the generator start and stop automatically
※ Adopt Modbus Communication protocol. Convenient to carry out the secondary development.
※ Adjusting the technical specification via RS485 is available.Convenient to adjust the different wind turbines for professional customers.
※ Support WIFI and GPRS.Customers can monitor the real-time working state of the on grid wind power system via PC and mobile and
query history working sate.Both Android and OS are compatible in Mobile.
※ For the different wind turbine, the controller can be equipped with mechanical yawing, Rotate tail control, furled empennage, mechanical
brake,hydraulic brake, electromagnetism brake and other brake functions.

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, 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.
Off grid system diagram
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.
