Low Frequency Power Split Phase Inverters

Low Frequency Power Split Phase Inverters RI-LF-SP

RI-LF-SP series is a low frequency pure sine wave split phase inverter with capacity from 1KW-6KW, DC 12V/24V/48V. It’s applicable to 110VAC/120VAC markets demands, which matches AC 110VAC/120V single phase, or two phase 110VAC/120V 120V/240V;

In LCD display, you can set output voltage, frequency, charging voltage, charging current to design best use based on different loads applications; meanwhile, you can also connect extra solar charger controller to build a solar home system, take use of sunshine freely and save electricity bills.
