ZXHP W551 Power Master

Based on the unified supervision of CSU (control & supervise unit) to solar charge controllers, wind turbine charge controller, switching mode rectifiers and batteries, ZXHP W551 power master can manage different energy input （including solar energy, wind energy, mains and generators）and output distribution (including loads and batteries ) on a leading unified architecture.

Technical Features

• Integrated Design
  Multiple controllers for different energy are integrated in one cabinet with a compact structure; as a result, the total occupancy area, cable usage and construction are reduced effectively.
  Based on the principle of green power priority, solar energy and wind energy are designed as prior inputs in power master for loads, to make full use of green power and save traditional energy.
• Modular Design
  The charge controllers and switching mode rectifiers are designed to be embedded modules which are fit for 19-inch rack. They can be configured flexibly according to load and site condition. It is convenient for site expansion as well.
• MPPT Technology
  MPPT（Maximum Power Point Tracking）technology is applied to solar charge controllers, which can increase power output efficiency by 30% at most under the same radiation. Thus the numbers of solar cells can be cut down.
• High Frequency DC-DC Technology
  Since the high frequency DC-DC technology is applied creatively, the solar charge controllers, wind turbine charge controllers and switching mode rectifiers have high power density. Compared to traditional product, they are smaller by 50% in size and much more competitive in cost.
• Energy-saving Dormancy
  Energy-saving dormancy is adopted in solar charge controllers and switching mode rectifiers. With automatically control of CSU, redundant modules can be turned on or off softly according to the actual load to make sure the rest modules working in a highly efficient rate, therefore, the efficiency of system is improved greatly.
• Unified Management for Batteries
  Power master can coordinate the charging of different energy to batteries, and also have the functions of charging current limit protection, temperature compensation and LVLD(low voltage load disconnect ) etc..
  By using power master with unified management of CSU, the life of batteries expands by 15%.
