You might also be concerned about the amount of power that your solar/battery system can provide. A special "emergency load" panel must be run from your home's breaker box to carry all the emergency loads that don't overload the batteries or solar panels. There is likely no mention of the air conditioner, oven, or clothes dryer, for example. In that case, the transfer switch must connect only those loads when the main power goes out. It is actually very good that there is a 30 second delay. As soon as it comes back online, it will make sure the utility power is reliable. don't try to do this on your own! Hire a licensed and experienced electrician to do this for you!
This generator makes a big "snap" when switching from campground power to the generator, and vice versa, but it does not make a noise when it is
By prying the latches open with a screwdriver between the lid and the case, the lid can be opened. It will probably be necessary to use a very short screwdriver, but not impossible, if you mount the box (as I did) with little in the way of clearance around it.
How the transfer switch was wired will probably be the key to finding the answer. In this panel, half of the power comes from each phase of the 240-volt power supply. It's necessary to supply both halves of the generator with 120v if one phase is 120v. A jumper can be used on the generator line side of the transfer switch to accomplish this. It would be a bad idea to have it on the load side. You should have two connections on the utility power line and two on the generator line, if your wiring is correct.
