300-500VDC input off grid inverter

Product Description

^{300-500VDC input off grid inverter}

Introduction

SANDI 3 Low Frequency Off Grid Pure Sine Wave Inverter is one of the most advanced DC to AC conversion products in the world, its widely used in 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, output pure sine wave, applying to capacitive, inductive and nonlinear mixed-load, with superior load capacity, perfect protection of overload, short circuit, low/over battery voltage, improper operation etc, reliable and safe to use.

Features:

• Standard rack mount cabinet, front and back side with ventilation holes for good cooling performance.
• Small size(Width*Height*Depth):
• 435*605*267mm:1-6KW single phase 9U
• 435*635*400mm:5-12KW three phase 6U
• Light weight, product net weight is about 40-120kg
• 100% full power output
• High efficiency > 94%
• Two kinds of start mode Variable frequency start(soft start) and step down voltage start
• RS485 monitoring, AC bypass(grid or generator) input, built in solar charge controller(Optional)
• Built in low frequency isolation transformer, which ensure the AC busbar and DC busbar are completely isolated, the harmonic and interference is very little, suitable for all types of load.
• Suitable for off grid without battery system, the DC input voltage range can be choose from 48-100V or 100-300V or200-500V or 400-800V or others customized voltage range.
• Can continuously work for 7*24h, the design service life > 15 years.
• Big LCD display, parameter setting flexible,input and output voltage,frequency can be set on LCD.
• Power range: 1kw-12kw, can be customized to customers requirements.
