Universal Generator AVR Voltage Regulator Rectifier for 5000-9500W Engines


SKU B09MJ785FJ Category


Replace your worn out or faulty AVR voltage regulator with this heavy duty aftermarket unit designed for generators from 5-8KW. This universal AVR regulator rectifier is compatible with a wide range of popular generator brands and models including Honda, Predator, Champion, Firman, Powermate, Duromax, and more.

Maintains Proper Voltage Output

This AVR voltage regulator helps your generator maintain consistent 120V or 240V AC output by regulating power flow and minimizing fluctuations. The automatic voltage regulation stabilizes voltage levels during load changes or when connecting multiple devices. This gives you clean, steady power ideal for sensitive electronics and appliances.

Direct Replacement AVR

This aftermarket AVR is made to OEM specifications and is a direct replacement for the stock regulator rectifier unit on GX and clone engines in the 5000-9500 watt range. It bolts directly on with the same 3 mounting holes and quick connect wiring as the original AVR. Easy to install in 10 minutes or less.

Durable and Reliable

The all metal construction and quality components ensure this universal AVR regulator can withstand engine vibration, heat, and load changes. The heavy duty rectifier diodes efficiently convert the AC output to DC to charge the starting battery. It comes with a new carbon brush to maintain optimal voltage sensing.

Broad Generator Compatibility

This voltage regulator rectifier fits a wide range of popular portable generators including:

– Honda EU5000 EU6500 EU7000 EU7000is
– Predator 3500-8750W inverter and conventional generators
– Champion 3500-9500W generators
– Firman, Powermate, Duromax 5000-9500W portable generators
– Lifan, Jiangdong, Wen engines
– Powerstroke, Powerland, Strongway, Buffalo Tools, Sportsman generators
– Generac, All Power, Windstorm portable generators

Easy Installation

Installation takes just 10-15 minutes using basic hand tools. Simply unbolt the old AVR, disconnect the wires, then bolt the new regulator rectifier in place and reconnect the wires or quick connectors. Refer to your generator manual or contact us for any installation help needed.
