The 20 GTA/GTAC becomes an essential part for those commercial boats with larger electrical demand, thanks to its 4 cylinder block engine as it is able to work smoothly for long periods. It is assembled on a 4 cylinder Mitsubishi block and this three phases marine generator performs 15,6 kW – 19,5 kVA at 1800 rpm and 60 Hz. The sound shield (canopy) version makes the navigation more enjoyable and free of disturbing noises. There is a wide range of kits at disposal for those boats, which requires a demanding configuration; also synchronism for parallel operation, and DNV type approval from IACS, for those boats that demands the highest standards in terms of security.
