SANDI SDP series low frequency off grid inverter suitable for Lithium/LiFePo4 battery, it has high conversion efficiency, high instantaneous power and low loss, output pure sine wave suitable for capacitive, inductive and nonlinear mixed-load, full power output with stronger capacity to drive load, perfect protection function against over load, short circuit, over temperation, under/over voltage, improper operation etc, which won't cause inverter failure. Suitable for all kind of AC load, widely used in solar system, wind system, solar-wind hybrid system.
Easy to repair
Adopted Japanese Mitsubishi IPM intelligent module, modular and simple structure design, very easy and convenient for maintenance, any fault only need use send you parts for replacement, maintenance is low-skill work.
Little fault rate
It with powerful protection for short circuit, over load and over temperature which is more safe and reliable. Fault rate < 2%.
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.
Efficiency > 94%
AC bypass input(optional)
AC power priority or battery power priority can be set
The DC input voltage range(under voltage point, under voltage recovery point, over voltage point, over voltage recovery point, under voltage recovery time) all can be set, convenient for adding or reducing the quantity of solar panel or battery in the future. The output voltage and output frequency can be set too.
Two kinds of start mode
Variable frequency start and Step down voltage start. With stronger capacity to drive inductive load.
