PS-35K Hybrid Power Supply System

1. Summary   

This hybrid power system is characterized by module design, makes the  system scalable and extendable from 2kW up to 35kW, so the users have  the possibility to consider investment in phases.  One subrack will hold all the modules including one monitor module and  others controlling modules used  for all optional energy sources either from  mains, diesel generator, solar, wind or battery bank.  The consequence of charging and discharging status can be set on the  LVD connected to the  monitor module with priority of utilizing  renewable energy. It will serve as a main or supplement power supply, saving a lot for the  telecom BTS, small and  medium size enterprises, corporate, and  government buildings.

2. Main Performance      

System can simultaneously manage either solar, wind, main AC power or diesel gen-set AC power combined with Sacred Sun’s all optional battery banks to supply the full solution  of energy storing system;All main components are designed in module type, so users can make up the power system as per their own will and budget;System using solar and wind energy resources of priority to save as much as fossil fuel while ensuring the continuous power supply;All modules can be connected in parallel to extending the capacity, with characteristic of high reliability, simple combinations, and easy expansion;One monitor module controlling all other modules, is of multiple functions of monitoring, alarm, automatic over-voltage, under-voltage protection and power-limited protection , extended control capabilities;System has a standard RS232 interface, or the installation of GPRS Modem, can be wired or wireless remote monitoring;
