I'm working with a 240v split phase 6000w inverter that's connected to a generator and batteries, mainly supplying power to a sub panel for four refrigerators. Most of the time, it runs on mains power, switching to the battery during outages. I want to know what options are available for bypassing the inverter entirely for a couple of weeks if it requires repairs or replacement. Would installing a dedicated bypass system be feasible?

Consider installing a double throw switch that can directly connect your mains to your sub panel, which allows you to bypass the inverter. You can find these switches at hardware stores. However, make sure to have it done by a qualified electrician for safety reasons!
A good option is to set up a manual transfer switch (DPDT) that lets you switch from the inverter to direct mains power easily. This switch will have three positions to manage the connection and ensure that you can bypass the inverter without any hassle. You can check out some installation manuals from companies like Schneider for more details on how to set it up. They have solid guides available online!
Would I need two switches? One before the inverter and one after, or could I split the mains to feed both the switch and the inverter at the same time? How would I handle the ground and neutrals with this setup?
