Review on VOLTWORKS 2000Watt Car Power Inverter Converter DC 12V to 120V AC with Remote Control, LCD Display, 1 AC Terminal Block, 2 AC Outlets, 2x2.4A USB Ports for RV Truck Boat – Pure Sine Wave (12VBlue) by Jessie Ritchie

I bought this inverter when I changed my system configuration to 24V. My old inverter was 12v 1500w pure sine wave and ran at around 115v. It worked ok most of the time but couldn't. I can't get along with my big ShopVac and even with a light load the inverter fans would come on every few minutes. This inverter runs everything I connect to it at the same time, including the ShopVac and the fridge. Its output is 120V, with high loads the voltage drops a little. At 1200W, the voltage never drops below 117V and averages around 118V. The fan rarely runs, in fact it never turns on when the continuous load is less than 150W. So for me it will run my fridge and be completely silent. At first I was concerned that the fans might not work, but the device stays cool and the fans work. The fan only works when the unit reaches 104F, so just leave the inverter in the conditioned room <80 degrees and you're good to go. Burden). Shutdown performance was in the milliamp range. I didn't like the remote control and lack of pinout information as I use a relay to operate the inverter. To turn on the inverter, you can either; Press the button on the device, the button on the remote control or use the relay to close pins 1+2 on the RJ9 port for ONE SECOND. With a shorter duration, the device is more likely to fail because the device needs to reach the correct voltage to start. I didn't like using the RJ9 port, it's a narrow connector used in handsets. Make it "unusual" for work. And I had to buy some RJ9 crimp connectors for my desktop stash. The RJ9 port pin 4 information is a kind of pulse encoding, much like the garage door encoding on my oscilloscope, and the pulse width and amplitude seem to follow the load. . I just process it as an analog signal (millivolts) to determine if the inverter is on or not. The handheld remote works, but having that cord is like being tied to a leash. It just looks like it's from the 80's. Hoping for more information from the company. Apart from these few issues, I rate this inverter as excellent.
