HanSeo series Pure Sine Wave Inverter is the one of the most advanced technology DC to AC conversion products in the world, it’s suitable use for areas without electricity, providing a complete power solution for strict demand applications. With SVPWM technology it has high conversion efficiency, high instantaneous power and low losses power output pure sine wave, applying to capacitive, inductive and nonlinear mixed-load, with superior load capacity, perfect protection function: overload, short circuit, low/over battery voltage, improper operation etc, which won’t cause mechanical failures. This Inverter is very suitable for solar power systems, wind power generation systems, wind and solar hybrid generation systems. The inverter can supply AC power to all kinds of electric equipment, air conditioners, electric motors, refrigerators, fluorescent lights, televisions, electric fans and other industrial power supply.

Technical Features:

Using the sixth generation efficient IPM intelligent module from Japanese Mitsubishi, high efficiency and stable performance. It with powerful protection function, the protection for short circuit, over load, over temperature is more safe and reliable. It’s service life can up to 15 years or more.

According to the product configuration conditions, adjustment the system usage mode: DC(Battery/Solar) priority or AC mains bypass priority can be set.

Two kinds of start mode: Reduction Voltage Start and Variable Frequency Start. Customers can set start mode according to the type of their load. This function is very convenient for users and also reduce frequency converter’s usage, which reduced the cost of equipment investment, easy to connect wires and control.

The output frequency can be setting via LCD panel, it’s very convenient for customer.

The output voltage can be set between -40 % to +20 % of rated voltage. And the output voltage is very accuracy ±1%.

The DC input voltage range can be set. Over-voltage point, under-voltage point, over-voltage recovery point, under-voltage recovery point all can be setting via the LCD panel.

Pure sine wave output. With good dynamic response less than 50MS, waveform distortion rate smaller, higher conversion efficiency and stable output voltage.

Built-in low frequency isolation transformer, strong impact resistance, available with motors, pump, air conditioners and other high impact equipment. At the same time DC busbar and AC busbar are completely isolated to avoid interference.

Wide input voltage can be set according to customer’s requirement. Input voltage range can be selected from 100-300V, 200-500V or 500-850V, suitable for solar/wind system without backup batteries, it can save many cost and maximization use the solar/wind energy.

Using SVPWM space vector algorithms, high conversion efficiency, high instantaneous power and low losses conversion efficiency up to 94%.

Powerful data display function. LCD can display the DC input voltage, output frequency, phase voltage, phase current, AC bypass input voltage, output power KWH, time and date, temperature, fault code display.

European CE (EMC, LVD) certificate, accredited by Australian CEC, ERAC energy network.


RS485 remote monitoring;

Can add AC bypass input complementary function;

 Low Frequency Off Grid Inverter Advantages
Easy to repair
*Adopted Japanese Mitsubishi IPM intelligent module, Modular and simple structure design, very easy and convenient for maintenance, any fault only need us send you parts for replacement, maintenance is low-skill work
Little fault rate
It with powerful protection function for short circuit, over load and over temperature which is more safe and reliable. Fault rate < 1%
100% full power stable output
Inside with full power low frequency isolated transformer, 100% full power output, can work 24h*7, which ensure the AC busbar and DC busbar are completely isolated, the harmonic and interference is very little, constant voltage and constant frequency stable output.
High efficiency
> 94%
Long service life
> 15 years
AC bypass input can be set
AC power priority or battery power priority can be set
Setting flexible
Wide DC input voltage range can be set: The DC input voltage range(over-voltage point, under-voltage point, over-voltage recovery point, under-voltage recovery point and under voltage recovery time) can be set, convenient for adding more solar panel or battery in the future.

The output frequency 50Hz/60Hz can be set: Variable Frequency Start control motor speed.

The output voltage can be set.: the accuracy of output voltage is very high less than 1%.

Two kinds of work mode
Variable Frequency Start or Step Down Voltage Start

with higher capacity to drive motor inductive load, normal inverter’s power need enlarge 3-7 times at least, however our inverter with VFD function, inverter’s power not need enlarge times, for example: 5KW inverter can take 3kw-5kw pump

Big LCD display
*LCD display the DC input voltage, output frequency, phase voltage, phase current, AC bypass input voltage, output power KWH, time and date, temperature, fault code display.
2 years warranty(whole life technology support)
Certificate: CE(EMC&LVD), UL1741, CSA22.2
