All-in-one solar charge inverter 4
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.
