Yo Power Three Phase 40kw Solar Power Inverter Pure Sine Waveform
Output
This YQLI-40KW inverter is one of the most advanced DC to AC
conversion products in the world. It adopts Mitsubishi sixth IPM
power module, Schneider control and other high quality materials.
It has pure sine waveform output, four wire (3 phase+ground) and
more than 94% conversion efficiency. This kind inverter can be work
with battery or solar panel/Wind generator directly. It’s widely
used for solar energy, wind turbine and other renewable energy
systems which usually install at mountains, pastoral, border,
island, vehicles, ships and other areas without electricity which
can provide and guarantee effective power supply. It has the main
advantages of high quality sine wave AC output, microcomputer
control, humanness design, high efficiency, low no-load loss and no
pollution. The inverter can also supply AC power to all kinds of
electric equipment, air conditioners, electric motors,
refrigerators, fluorescent lights, televisions, electric fans and
other industrial power supply.
1. Advantages
- Save cost: it can work with solar panel directly, without battery
and solar charge controller, the inverter makes the whole system
more economical
- Voltage stabilizing: the inverter has high precision voltage
stablizing and filtering, when utility grid power is unstable or
poor, the inverter can give out stable voltage and high quality
pure sine waveform, the voltage transient response is less than
40ms
- 0 second seamlessly switch between DC power and grid power: when
solar power or battery power is poor, inverter will automatically
swith to grid power immediatly. The switch time is 0 seconds
- Unique anti-oscillation function: when there is no grid power
input, the inverter still can running stably and independently. It
won't happen to turn on/off repeatedly these oscillation problems
- High efficiency: if it work with solar panel direcly, with the
maximum power point tracking function, the using efficiency of
solar power/wind power can be up to 94%
- Durable&Long service life: anti-sand, resistant to moisture and
salt, suitable for harsh environment, the designing service life
more than 15 years
2. Features
- It adopts the sixth generation efficient IPM intelligent module
from Japanese Mitsubishi. This makes the inverter high efficiency
and stable performance. It also has powerful protection function
for short circuit, over load and over temperature which is more
safe and reliable. It's service life can up to 15~20 years or more
- Intelligentized, modularized and simple structure design, very easy
and convenient for install and maintenance.
- Two kinds of starting models: The Step Down Voltage Start model is
suitable for any resistive loads, such as lamp, resistance,
computer and so on. The Variable Frequency Start model is suitable
for any inductive loads, such as pump, motor, welder and so on.
Customers can choose the starting model 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 inverters adopts SVPWM space vector algorithms, high conversion
efficiency, high instantaneous power and low losses conversion
efficiency up to 94%.
- The LCD display DC input voltage, output frequency, phase voltage,
phase current, AC bypass input voltage, output power,
time&date, temperature, fault code and so on.
- Users can set over voltage, under voltage, over voltage recovery
point, under voltage recovery point, DC input voltage range, output
frequency, output voltage range.
- Pure sine wave output with good transient response less than 40MS,
little harmonic distortion, higher conversion efficiency and stable
output voltage.
- The inverter uses black pure aluminum radiator and high quality
fans which could continuously work for 5 years and uninterrupted
work for 20 years.
- European CE (EMC and LVD) certification and accredited by Australia
CEC, ERAC energy network.
