CENTRAL INVERTER

IF SERIES of photovoltaic inverters developed by JEMA, profits from its 60 years experience designing and manufacturing industrial, robust, reliable, secure and high efficiency power electronics systems.

The IF series PV Inverter turns the DC mains coming from a PV field into an stabilized AC voltage power output. The inverter works in grid connected mode, injecting the produced power. 

• Solar Inverter 20-25-30 kW
• Solar Inverter 50-80-90-100-120 kW
• Solar Inverter 250-300-500-600 kW
• Solar Inverter 80-100 kW TL (without transformer)

General characteristics 

• Wide range of input voltages and transformer makes them compatible with all panels in the market.
• Indoor and Outdoor inverters.
• Option with or without transformer.
• Soft-start and high efficiency of the inverters from the begining.
• Maximum energy efficiency 98%
• Harmonic distortion of less than 3%
