Installed it on my generator and now I have electricity... It came set at 110 volts, I easily adjusted it up to 120 and now I can run my outdoor fans... It is too soon to say how long it will last, but well worth the price... Review: Finally a company product that works - Been trying to get an AVR that works. Others ordered from other companies failed and would not work. Purchased this one and it works great. All I had to do was tweek the voltage screw to increase it from 117VAC to 121.9VAC. I'm ordering another just for a back up. Its worth the cost to have this in stock ready to go during the winter in the event of some type failure. Its an electronic device so you never know. ## Features - Condition: Well packed - Replacement 6.5KW to 8.5KW Adjustable Generator Automatic Voltage Regulator(AVR) for BlackMax Portable Gasoline Generator Models: BM10500, BM10500G, BM10680, BM10680S, BM905000, BM905700, BM905700P, BM907000, BM907000A, BM10700D, BM10700DG, BM10700DR, BM10700H, BM10700HR, BM10700J, ZR10700, ZR10700J, ZR10711，ZR10722 - Over Voltage, Over Current and Short Circuit Protection - Large Manual Adjustable Voltage Output Range of 160V-260V for 240V output - Please compare the specific applicable models listed at below to make sure it'll fit ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07FVRGP55 | | Additional Features | Short Circuit Protection | | Best Sellers Rank | #815,924 in Automotive ( See Top 100 in Automotive ) #253 in Automotive Replacement Alternator Voltage Regulators | | Brand Name | Saihisday | | Color | Black | | Current Rating | 3.5 Amps | | Customer Reviews | 4.5 4.5 out of 5 stars (294) | | Engine Power Maximum | 8.5 Kilowatts | | Engine Type | 4 Stroke | | Frequency | 60 Hz | | Fuel Type | Gasoline | | Ignition System Type | Recoil start | | Included Components | Automatic Voltage Regulator | | Is Electric | No | | Manufacturer | Saihisday | | Material Type | Metal | | Model Name | 5000 5700 7125 8750 | | Model Number | 5000 5700 7125 8750 | | Output Wattage | 8750 Watts | | Power Source | Fuel Powered | | Recommended Uses For Product | Commercial, Residential | | Running Wattage | 8500 Watts | | Runtime | 20 hours | | Starting Wattage | 8750 Watts | | Total Power Outlets | 4 | | UPC | 657390260851 | | Voltage | 240 Volts | | Wattage | 8750 watts | ## Product Details - **Brand:** Saihisday - **Color:** Black - **Fuel Type:** Gasoline - **Included Components:** Automatic Voltage Regulator - **Output Wattage:** 8750 Watts - **Power Source:** Fuel Powered - **Recommended Uses For Product:** Commercial, Residential - **Special Feature:** Short Circuit Protection - **Voltage:** 240 Volts - **Wattage:** 8750 watts ## Images ![Saihisday Gas Generator AVR For BlackMax 5KW 5.7KW 7KW 7.5KW 9KW 5000 5700 7125 8750 Watt Automatic Voltage Regulator - Image 1](https://m.media-amazon.com/images/I/41k7AfkEKuL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Can this works on a duro Max xp1200eh?** A: I'm leaning towards 'no', as this AVR is designed for 5-9 kW generators. The Duromax XP1200EH is rated at 12kW and will require a higher exciter current. **Q: says this id manually adjustable. How do you adjust it, i dont see a knob?** A: It is manually adjustable to set then it maintains the set voltage afterwards. The know is that tiny flat head screw **Q: Does this work with a Predator 8750 generator?** A: Yes it does **Q: will this work on a champion 9000/7000 ?** A: Sorry wont work to small you need to find one for your exact generator get the right part not what you think might work this type of thinking could cost you more in the long run ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works great. *by W***. on September 17, 2024* Arrived right on schedule.
