Common Equipment Failures Solved

• Cannot connect computer to read genset running data, unable to modify controller protection parameters on site
• Ordinary non-isolated converter causes communication crash, data garbled, even burn controller and computer
• Single RS232 module cannot realize long-distance remote centralized monitoring of multiple gensets
• No surge protection, cabin high voltage surge easily damage communication module after long-time operation
• Generic conversion module incompatible with Smartgen proprietary Modbus data protocol, partial measurement data missin
