Reverse polarity outlet6/19/2023 ![]() ![]() If you disagree with me and the engineers, please explain your reasoning below. I also can't imagine how electrical engineers from multiple companies could all be wrong in the same way. But in this instance, I don't see an issue at all. If the outputs were in parallel to increase capacity (with some way to sync the waveforms), the relative "polarity" of the inverters output would matter. And after testing this five seconds ago, they are. What does matter is if the reference potential of grounding conductors across ac outputs is bonded. It's alternating current though, so it doesn't matter. It is only considered "reverse polarity" when using the other receptacles as a reference as to what "hot" and "neutral" is considered. There is no exposed case on these units, and it's a floating system. I had a lot of people email me this week about concern over bluetti/goalzero/ecoflow products having a reverse polarity RV plug. As a result, there is no specific hot leg and. It is a floating system, and grounds are bonded. This also means that both legs on the receptacle are hot legs, which is normal for floating neutral generators. Just posted this in my community section. ![]() Our only goal is bringing you peace of mind. Verbal statements are no guarantee, we've been testing the safety of these AC200MAX in our lab and the testing video will be shared here in this week. Is a floating neutral solar generator safe when the polarity is reversed? Electrical outlets with reverse polarity can cause fires, shocks, and short circuits. Meanwhile, even if there is no current flow, mishaps can occur if you mistakenly touch the damaged or incorrect section of the gadget. We are deeply sorry for the inconvenience caused and thanks goes to Dan Farren for pointing out this issue and make us better. While you have reverse polarity, current flows through your outlet even when your appliances are turned off. Usually would take about 5~15 days to get the work done(sequential maintenance), more details on this service shall be updated later. We offer adjusting service of the polarity and cover the shipment cost. What surge suppressor is it, brand and model please. If you feel uncomfortable using the AC200MAX with a reversed polarity TT-30, feel free to send it back to our service center in Vegas, NV. In AC terms, reverse polarity means that the hot and neutral wires are reversed. After a thoroughly internal investigation, we found that some of the AC200MAX had polarity reverse connection on the TT-30 socket due to negligence of management, corrections have been made and we promise this will not happen again. ![]() You can place one lead in the outlet’s longer vertical opening. You can now turn on the multimeter by turning the knob in the middle into Voltage AC. Then, you can plug the red lead on the right input. But, I wanted to get an idea of what the problem might be, so I can have a somewhat informed dicussion with them.**AC200MAX - Reversed Polarity of TT-30 Update** Plug black lead in the middle input on the bottom of your multimeter. We are going to have a qualified electrician come in to look at the problem. I'm not an electrician, obviously, but to me, this seems like an improperly wired GFCI receptacle. ![]() However, when I press the 'Test' button on the GFCI receptacle, the other 5 receptacles test as correct. Here is the problem: The 3 GFCI receptacles mentioned above are on the same breaker as 5 other receptacles and all 8 receptacles are showing an open ground. When I press the 'Test' button, on the GFCI receptacle, the 2 other sticker protected receptacles go dead (like they are supposed to). These other 2 are labled with a 'GFCI Protected' sticker. Our hall bathroom has a GFCI receptacle that protects 2 other receptacles, another bathroom receptacle and a vanity area receptacle with a sink. My wife and I just purchased an apartment in the Okanagan, British Columbia (It was built in 1993). ![]()
