MPPT Solar Power System is a new generation of outdoor multi-energy integrated power system with MPPT function. The MPPT solar power system is composed of a cabinet, a heat exchanger, a Monitor, a solar module, rectifiers, power distribution unit and fans, Lightning arrester and reserve user equipment space. high protection degree:IP55.
Features:
Multi-energy power supply solution : Can be connected to solar energy, wind energy, utility power, DG to form different types of complementary power supply system .
Energy-saving mode : Maximize energy saving, according to solar energy, wind energy priority, commercial power (DG) supplement, battery backup mode operation.
MPPT function : the maximum power point tracking accuracy is more than 99.5%. Efficiency≥96%(solar mode).
Battery management: Perfect battery management: guarantee the long life of the battery in the harsh grid environment.
Modular design: MPPT Module, Rectifier modules are modular hot-swappable, Flexible configuration, easy expansion and maintenance .
Protection degree : IP55, The high degree of protection cabinet and advanced temperature control design ensure reliable operation of the system in harsh outdoor environments.
Monitor :Providing one RS232 port, dry contact and other communication ports for network flexibility;
Enabling proximal end software upgrade and unattended
Power statistic : Load electricity consumption, solar power, mains, DG, wind turbine generated energy
Integrated and modular design of MPPT and rectifier module have been realized. Can be replaced online , support hot plug.
Wind controller is not integrated into the cabinet, only external, and need to connect its DC output to the integrated controller. Outdoor cabinet can only make ON/OFF control of wind energy, can not do voltage regulation management etc.
Provide fouth protection feature：
●Leeway：The head lean one side when strong wind
●Stall：stall type blade ，capture power＆voltage reducing when strong wind
●Stressing：Automatic stressing，reducing fan motor speed ＆output voltage
●Short circuit：SCR breakover automatically when output overvoltage，cut out the generator to protect other load .
High efficiency：
●Fan blade：airfoil，Cross-section trapezoid ，higher-performance than rectangle
●Desigh of impedance in generator:conform to features of discharge and charge of battery.Higher efficiency in dependent power supply system.
●Fan leaf diameter：EX,1kW fan,fan blade diameter 3m,can capture 1KW power at the speed of 9m/s
● Controller：MPPT
●System configuration：Recommend work by solar system and an auxiliary wind system.
Solar energy is more stable and reliable than wind energy. And in terms of return on investment，solar panels at the same cost produce more electricity than wind turbines in most cases.
Working priority：Wind module can not achieve voltage regulation control ，it’s directly connect to system bus through the contactor to realize power supply. However, solar and rectifier module are controlled by the same monitoring module. In a certain state, monitoring module issues an output voltage regulation instruction according to system state. The output voltage of MPPT module is slightly higher than rectifier module, thus realizing the priority power supply of solar.
Working mode: Firstly use the solar energy to power the load and charge the battery when the sunlight adequate; when the sunlight is not enough the solar energy and battery will power the load at the same time; when the battery voltage is not enough, the tanker will start and get through the rectifier model to power the load and charge the battery.
