1. Basic Information
1.1 Product overview and characteristics
HF/MF48-H series is a new type of mixed solar energy storage inverting & control all-in-one machine
integrating solar energy storage & municipal power charge storage and AC sine wave output. It adopts DSP
control and advanced control algorithm to achieve characteristics of high response speed, high reliability and
high industrial standard. There are four charge modes namely only solar power, mains power priority, solar
power priority, mains power & solar power; and two optional output modes, namely inverting and mains power
to meet different application needs.
The solar charge module adopts the latest optimized MPPT tracking technology, which can quickly track
the maximum power point of the photovoltaic array in any environment to obtain the maximum energy of the
solar panel in real time with wide voltage range of MPPT.
AC-DC charge module adopts advanced control algorithm to realize full digital double closed-loop control
of voltage and current, with high control accuracy and small volume. Battery can be charged and protected
stably and reliably with wide AC voltage input range, full input/output protection function.
DC-AC inverter module based on full digital intelligent design adopts advanced SPWM technology, outputs
pure sine wave, converts DC into AC. It is suitable for AC loads such as household appliances, electric tools,
industrial device, electronic audiovisual, etc. The product adopts the segment LCD display design to display the
operation data and state of the system in real time. The comprehensive electronic protection function ensures
that safety and stability of the whole system.
