Generator Output

The generator controller monitors the power generated by the alternator. From the output voltage, it can determine the engine speed in rpm, alternator frequency and voltage output are correct.  If they start to fall outside of set normal ranges, it will warn you and log it for future reference. Any critical errors will cause the generator to safely shut down.

Engine Specifications

This generator uses a Powerful four cylinder diesel engine from Perkins. While it is small and compact, it offers exceptional performance and long life.   Perkins engines are Radiator Liquid Cooled and can operate full or part time.   Perkins engines require fewer oil, air and fuel filter changes (every 500 hours depending on load factor). The low fuel consumption and ultra-compact engine offer all the customer benefits experienced from larger engine sizes. The engine has a proven record and has been in use worldwide for many years in providing power for homes, business and construction equipment
