1. General information

 

1.1 Product overview and features

 

HF  series  is  a  new  all-in-one  hybrid  solar  charge  inverter,  which  integrates  solar  energy  storage  & 
means charging energy storage and AC sine wave output. Thanks to DSP control and advanced control 
algorithm,  it  has  high  response  speed,  high  reliability  and  high  industrial  standard.  Four  charging 
modes are optional,  i.e. Only  Solar, Mains  Priority, Solar  Priority and  Mains  & Solar hybrid charging; 
and two output modes are available, i.e. Inverter and Mains, to meet different application requirements. 
The  solar  charging  module  applies  the  latest  optimized  MPPT  technology  to  quickly  track  the 
maximum  power  point  of  the  PV  array  in  any  environment  and  obtain  the  maximum  energy  of  the 
solar panel in real time. 
Through a state of the art control algorithm, the AC-DC charging module realizes fully digital voltage 
and current double closed loop control, with high control precision in a small volume. Wide AC voltage 
input  range  and  complete  input/output  protections  are  designed  for  stable  and  reliable  battery 
charging and protection. 
Based  on  full-digital  intelligent  design,  the  DC-AC  inverter  module  employs  advanced  SPWM 
technology  and  outputs  pure  sine  wave  to  convert  DC  into  AC.  It  is  ideal  for  AC  loads  such  as 
household appliances, power tools, industrial equipment, and electronic audio and video equipment. 
The product comes with a segment LCD display design which allows real-time display of the operating 
data and status of the system. Comprehensive electronic protections keep the entire system safer and 
more stable.
