30KW Off-Grid Pure Sine Wave Inverter
Features：
Our company combine user’s actual usage, specially designed this new low frequency off grid inverter, which is characterized by stable and reliable performance, set up parameters flexibly. It can meet different user’s different requirements, the characteristics as following:
- Using the fifth 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 and overtemperature which is more safe and reliable. It’s service life can up to 15-20 years or more.
- Intelligentized, modularized, simple structure design, convenient for maintenance.
- Two kinds of start mode: Step Down 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 set via LCD panel. It’s very convenient for customer.
- The output voltage can be set between -40 % to +20 % of rated voltage. And the accuracy of output voltage is very high less than 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 set via the LCD panel. Convenient for increasing or reducing the quantity of batteries and photovoltaic modules in the future.
- Pure sine wave output. with good transient response less than 50MS, little harmonic distortion, higher conversion efficiency and stable output voltage.
- Low frequency transformer, which ensures inverter with higher efficiency >94%, and very little no-load loss.
- Powerful data display and fault instruction 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.
- Wide input voltage can be set according to customer’s requirement. Input voltage range can be selectedfrom 100-500v, 200-850v.
- High conversion efficiency, Max. Efficiency≥96%
- Could add AC bypass input: Battery Power Priority or AC Bypass Priority optional
- Adopts black pure aluminum radiator, which confirms the best radiating performance.
- Adopts high quality fan, 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.
[Optional]
- RS485 remote monitoring;
- Can add AC bypass complementary function;
