SFE Solar Inverters

SFE Solar inverter is a new type of hybrid solar energy storage inverter control all-in-one machine integrating solar energy storage & utility charging & storage and AC sine wave output. It adopts DSP control, and through advanced control algorithms, it is characterized by high responsiveness, high reliability, and high industrialization standard.
SFE Series inverter has four charging modes selectable: solar only, utility priority, solar priority and utility & solar; two output modes selectable: inverter and utility to meet different application requirements.

Voltage Converters

Voltage Converters

Our voltage converters help to power your devices in another country than what they were initially intended. Make sure you select the right size converter for your application, as sizing it too small will result in the fuse blowing constantly.

Pure Sine Wave Inverters

Pure Sine Wave Inverters

Our pure sine wave inverters, sometimes known as true sine or pure wave, provide quality AC power for all of your devices. Our models produce an output wave that is equal to or better than what you might receive from the power company to your home or office.

Voltage Converters

Modified Sine Wave Inverters

Our modified sine wave inverters are an inexpensive way of converting your 12 or 24 volt DC battery bank into 110-120 volt AC (North American electrical power). These are a common and economical choice for most customers looking to install an inverter in their vehicle, camper, RV, and stationary setups.
