Product Description

Our vision to excel and establish a strong foothold in the market has assisted us to evolve as a prominent manufacturer and exporter of Low Frequency Inverter. This inverter is perfect for off-grid or back up power system. Our diligent workforce uses quality grade materials and components to manufacture this inverter. Inverter converts the DC power stored within a battery into AC power. The output power is used to run your household items and electrical appliances, from fridges to televisions. We make available this Low Frequency Inverter for clients in different specifications as per their requirements.

Features:

Easy to install
Longer working life
High working efficiency

Introduction:

Sandi SDP series Low Frequency Inverter is one of the most advanced DC to AC conversion products in the world. It's widely used for solar energy, wind turbine and other renewable energy systems. It has the main advantages of high quality sine wave AC output, 100% full power can work 24h*7, high efficiency, low no-load loss, powerful and complete protection which is more safe and reliable, setting flexibly and many unique functions, like variable frequency start, input output voltage, frequency can be set, AC bypass input and Monitoring optional. SANDI inverter's cost performance is the highest compared with others.

We also have won great reputation for earnest service and professional technology support all the time.

Advantages:

Using the sixth generation efficient IPM intelligent module from Japanese Mitsubishi, high efficiency and stable performance. It with 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 maintenance.
Two kinds of start mode: Step Down Voltage Start and Variable Frequency Start.
The output frequency 50Hz/60Hz can be set.
The output voltage can be set.
The DC input voltage range can be set. over-voltage point, under-voltage point, over-voltage recovery point, under-voltage recovery point and under voltage recovery time all can be set via the LCD panel.
Higher efficiency > 94%.
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 ensure the AC busbar and DC busbar are completely isolated to avoid interference, high efficiency 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 selected from 100-400v or 200-600v or 400-850v. This wide voltage input off grid inverter can work without battery and solar charge controller, which save battery cost and same like with MPPT function can maximum make full use of solar power .
AC bypass input function optional: Battery Power Priority or AC Bypass Priority work mode can be set.
RS485 remote monitoring function optional
European CE (EMC and LVD) certification, accredited by Australian CEC, ERAC energy network, meet UL1741 and CSA22.2 standard.
