Controlled by a microprocessor, the SI3-I solar inverter enables the use of sunlight as an energy supply in stand-alone operation.
It converts a DC voltage on the input side into three AC voltages that are electrically shifted by 120 ° (technical three-phase current). The DC supply can be provided by photovoltaic generators, accumulators and other DC systems.
The SI3-I generates and monitors a three-phase system for the operation of motors and other technical devices with three-phase current. There is a complete electrical isolation between the performance potential and all measurement and information technology signals of the microprocessor unit.
As an off-grid system, the inverter does not require any additional power supply.
