The SolarTronics inverter modified sinus is designed to convert one-way to alternating current. Converters of 12V or 24V convert into alternating current 220V (230V) with which we supply electrical consumers. The modulated sinus inverters are designed especially for powering lights, TVs, radio and other less demanding electrical consumers. In the case of hand tools, sometimes a modified sinus converter is not powerful enough (depending on the type and the characteristics of the hand tool), so you must also consider this!
