SIS4 Series OffGrid Solar Inverter
The SIS4 series off-grid solar inverters are equipped with a color LCD display and a wide range of communication options. They offer ease of use through remote control capabilities via a mobile application. With a pure sine wave output, they ensure high stability and reliability. Additionally, the user-friendly replaceable fan design makes maintenance operations both safe and effortless.

Product Description
The SIS4 series off-grid inverters are ideal for residential energy storage solutions. The system stores energy harvested from the sun in batteries and prioritizes solar panels during active consumption. In cases of insufficient weather conditions, it converts the energy stored in the batteries into household electricity; should the battery be depleted, it automatically switches to the grid without any interruption.
