Eifmgs---micro grid system micro grid system is composed of micro power, storage system, control devices and load. It is separate unit from grid, with functions on self-control, self-protection and self-management; it can operate separately and can also be grid-connected; it can be a power supply or a load to outer grid.   micro power  it includes solar power, wind turbine and other types of fluctuated and discontinuous renewable energies. Most are small capacity distributed energy.   storage system   divided into energy type (such as, lead acid battery, lithium battery and liquid flow battery) who improves utilization efficiency of renewable energy and power type (such as, flywheel, super capacitor) who ensures stability at accidents of micro grid connecting to griddisconnecting, power supply or load switching operation.   control devices control devices are the hardware and software equipment to make sure micro grid system operates stably, provide relay protection, dispatch, etc.   load divided into critical load and secondary load; intelligent load, adjustable and non-adjustable load.       eifmgs core business with products & services of micro grid system   1, develop, manufacture and sell multi-in-one power system: small capacity wind turbine (horizontal: 1-300kw; vertical: 1-10kw), solar power system, storage system, control device; 2, develop, oem manufacture and sell big capacity control system; 3, develop and sell control system software; 4, consultant, design, and management for projects on micro grid system and hybrid power plant.

Solar powered pump irrigation system product over review “eifpmg” solar pump irrigation system is composed of solar panel, solar charge controller, pump and accessories. If ac system, an inverter will be needed. A battery storage is necessary for continuous use. Submerged multistage centrifugal pump irrigation system is most common type used. We commonly utilizes a brushless dc motor. Controller adjusts output frequency according to sun light intensity. When sunshine is strong, pump runs at rated speed; when is weak, lower than rated speed, so as to keep pump running steadily. main features the solar pump irrigation system operates full-automatically. Mppt tracking max power method makes pump run as sunshine goes. battery storage system can make the system run at normal at night. If without battery, also can be available but only work at day time. main circuit adopts intelligent power module, with high reliability, transfer efficiency over in excess to 98%. with multi protection functions of lighting proof, over-voltage protection, low-voltage protection, over-load protection, etc motor protection functions on level monitoring, preventing from overflow and being drained are optional. applications & functions show lift water from river to water tank for irrigate plant. Solar powered system for house application including lawn irrigation with pump solar pump irrigation for city greening common use for plant irrigation

Lift type vertical axis wind turbine introduction basing on iec 61400-2 (wind turbines—part 2: design requirements for small wind turbines, idt) and china national standard gbt29494-2013(small vertical axis wind turbines) and gbt 19115 ( off-grid type wind-solar photovoltaic hybrid generate electricity system of household-use), we designed our new lift-type vertical axis wind turbines(vawt) and optimized all hybrid system. blade to improve the annual energy production and the system safety, we design the vawt low rated speed which means the lower tip-speed ratio. So, according to the general airfoil date, we develop a new airfoil. This new airfoil has the excellent aerodynamic performance and the structural strength. generator we designed the permanent magnet generator which has the lower cogging torque can ensure the lower cut in wind speed and higher efficiency. controller and inverter all-in-one

W22 bldc motor & controller adopts most advanced motor controlling technology, with full functions to be realiable and operation-steadily. The system has been improved at efficiency and make realize re-brake, skid backward proof, false indication, thus improving range of one charge and safety performance. It is widely used in evs driving system solution.    main futures: * high performance micro processor. Precise speed and torque output, high efficient, smooth and low noise level. * electric commutation: high frequency pwm chopper modulation mode and continous stepless speed regulation. * programmable control function. User can modify paramters by hand-programmer. Flexible parameters setting can be customised for kinds of requirements. * fault diagnosis and multicolors led indication lights to show operation situation and faults types clear at a glance, convenient after-sales engineers call to solve fault, reduce the cost of after-sales service. * adopted synchronous freewheeling technology to make higher efficiency. * multi power-recycle start modes. Such as start at brake signal, commutation * rs-232 communication. Can be connected with external display terminal. * temperature protection. At controller overheating current drops linearly, not suddenly shut off, to effectively guarantee driving safety. * low voltage and overvoltage protection. Effectively protect the battery and controller, prolong service life. * adjustable controller input power limit. It can avoid the battery output current is too big so that damages battery and circuit, effectively protect battery and safety of the circuit. * with new design of power structure and smd process. Make high reliability and electromagnetic compatibility. * large current adopts aluminum column outlet method
