Product Features
◆ Generator
◆ Blade
a. Steel generator body, disk-type and ironless outer rotor, which
prevent corrosive gas from intruding into the innor of generator. Not
easy to deform and magnet steel will not drop off.
b. Light in weight, low temperature-rising, low starting torque, low
start-up wind speed.
a. Soft blade is designed by Japanese expert of wind power to
match the generator. Adopt spiral, bud-shaped
macromolecule hydrocarbonpolymer.
b. No pollution, corrosion resisting, endurable, light weight,
obdurability,easy to made, low cast.
c. Surface texture likes sharkskin, which reduces noise.
d. Unique design improves the adaptability for variable wind
speed, further to improve energy conversion efficiency.
e. Automatically adjust rotation, and it avoids system damage
at high wind speed.
f. Well restrain on wind turbulence.
g. Safety, fatal injury will not be caused even the balde crash
on humans and animals.

◆ Controller
Application of Energy Storage System
Networking of of Energy Storage System
a. Microcontroller is used in this system. Industrial level
componets are selected. It can be used under very hot, cold
and humid environment.
b. Intelligent battery charge/discharge control, high efficiency
and long service life.
c. It has optical and timer control function.
d. Open circuit and short circuit protection, auto recovery and
lighting protection function.
e. Easy to install, use and maintain.

Installation
(Portable installing frame) （Lamp post type）
Only available when wind speed is low Available to high wind speed
Installation and Requirements of Installation Site
A.In order to obtain wind, wind driven generator should far away from obstacles and it be put as
high as possible.
B.Soil texture of installation site should be considered. Don’t choose the place with soft sand, rough
ground and places that will affected by climate.
C.Distance between wind driven generator and battery should also be considered. Please select
standard electric cable .

Application of Eco-Pole® Energy Storage System
Configuration Design Philosophy
1 . Wind Generating Set
1.1 Power of wind generating set will be caculated according to annual average wind speed,
minimum average monthly wind speed, duration without effective wind speed as well as the
power used per year.
1.2 Rated wind speed of wind generating set will be choosed according to lowest average monthly
wind speed per year.
1.3 When the total power is the same, 2 or more wind generating sets are allowed to use at DC
output end in series or in parallel.
2 . Solar Battery Components
2.1 Peak power of solar battery componets is decided by minimum power consumption per day,
sunshine hours when there is no effecitve wind speed as well as damage of the system.
2.2 Under normal conditions, minimum power of solar battery components will meet power
generating capacity and its 1.8 times higher than the lowest average power consumption per day.
3 . Controller
3.1 Controller must equip with wind generator charging circuit and photovoltaic charging circuit
and 2 circuits must be seperated effectively.

3.2 Maximum power of controller’s wind generator charging circuit should greater than or equal to
2 times of rated output power of wind generating set.
3.3 Maximum power of controller’s photovoltaic charging circuit should 1.5 times higher than
photovoltaic power of the system.
4. Inverter
4.1 Output power of inverter should be calculated according to electrical equipment’s type, power,
and time used by user.
4.2 Rated output power of inverter should 1.2 times higher than the total power of system.
5. Battery
5.1 lead-acid storage battery and storage battery that suits for wind solar hybrid generator are
preferred.
5.2 Series voltage of storage battery should match with the output voltage of wind generating set
and solar battery componets.
5.3 Capacity of storage battery is decided by minimum power consumption per day, continues
cloudy day , maximum no wind days and technical function of storage battery such as
self-discharge rate, charge-discharge efficiency and depth of dischare.
Natural Conditions﹠Environmental Requirements (wind solar hybrid power generating system)
