Fangpusun  Sine Wave 1800W Inverters

Provides 1800 watts of sine wave AC power from a DC source

Offering superior quality ture sine wave output, the PROsineTM 1800 stand-alone inverters are ideally suited for electrical systems that already have a quality multistage battery charger. Designed for recrestional and industrial applications, their 240-volt, 50HZ AC power output is capable of handing both heavy duty and smaller, multiple AC loads. PROsine inverters include a backlit LCD display panel, which can be mounted remotely.

Automatic AC Transfer Switch

The switch allows an appliance to be powered from either mains power or the inverter (battery power). The inclusion of the AC transfer makes it ideal for permanent installation into caravans, motor homes, work vehicles etc ensuring a quick transfer of AC power when switching from battery power to mains power and vice versa. The automatic change-over function means there is no need to manually swap over AC plugs or be switching dials between the two power sources.

True sine wave power

With less than 3% total harmonic distortion, PROsine 1800 inverters deliver true sine wave output that is identical to AC power supplied by your utility. This clean output makes PROsine inverters ideal for handling sensitive loads and improves AC equipment performance. Expect trouble-free true sine wave electricity for televisions, audio systems, variable speed tools, and more.


Light and compact

PROsine inverters are lighter and more compact than other inverters with similar power ratings because they use high-frequency switching technology in the power conversion process.
