Important safety instructions
Please keep this manual for future use.
This manual contains all safety, installation and operating instructions for the HF Series all-in-one solar
charge inverter.
Please read all instructions and precautions in the manual carefully before installation and use.
Non-safety voltage exists inside the all-in-one solar charge inverter. To avoid personal injury, users
shall not disassemble the all-in-one solar charge inverter themselves. Contact our professional
maintenance personnel if their is a need for repair.
Do not place the all-in-one solar charge inverter within the reach of children.
Do not install the all-in-one solar charge inverter in harsh environments such as moist, oily,
flammable or explosive, or heavily dusty areas.
The mains input and AC output are high voltage, so please do not touch the wiring terminals.
The housing of the all-in-one solar charge inverter is hot when it is working. Do not touch it.
Do not open the terminal protective cover when the all-in-one solar charge inverter is working.
It is recommended to attach proper fuse or circuit breaker to the outside of the all-in-one solar
charge inverter.
Always disconnect the fuse or circuit breaker near the terminals of PV array, mains and battery
before installing and adjusting the wiring of the all-in-one solar charge inverter.
After installation, check that all wire connections are tight to avoid heat accumulation due to poor
connection, which is dangerous.
The all-in-one solar charge inverter is off-grid. It is necessary to confirm that it is the only input
device for load, and it is forbidden to use it in parallel with other input AC power to avoid damage.

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.
Features:
1. Full digital voltage and current double closed loop control, advanced SPWM technology, output
of pure sine wave.
2. Two output modes: mains bypass and inverter output; uninterrupted power supply.
3. Available in 4 charging modes: Only Solar, Mains Priority, Solar Priority and Mains & Solar hybrid
charging.
4. Advanced MPPT technology with an efficiency of 99.9%.
5. Designed with a LCD screen and 3 LED indicators for dynamic display of system data and
operating status.
6. ON/OFF rocker switch for AC output control.
7. Power saving mode available to reduce no-load loss.
8. Intelligent variable speed fan to efficiently dissipate heat and extend system life.
9. Lithium battery activation by PV solar or mains, allowing access of lead-acid battery and lithium
battery.
10. 360 °all-round protection with a number of protection functions.
11. Complete protections, including short circuit protection, over voltage and under voltage
protection, overload protection, reverse protection, etc.

1.2 Basic system introduction
The figure below shows the system application scenario of this product. A complete system consists of
the following parts:
1. PV module: Convert light energy into DC power, and charge the battery through the all-in-one
solar charge inverter, or directly invert into AC power to drive the load.
2. Mains or generator: Connected at the AC input, to power the load while charging the battery. If
the mains or generator is not connected, the system can also operate normally, and the load is
powered by the battery and PV module.
3. Battery: Provided to ensure normal power supply to the system loads when solar energy is
insufficient and the Mains is not connected.
4. Household load: Allow connection of various household and office loads, including refrigerators,
lamps, TVs, fans and air conditioners.
5. All-in-one solar charge inverter: The energy conversion unit of the whole system.
Specific system wiring method depends on the actual application scenario.
