I'm currently using Enphase solar with an IQ7 grid tie and I'm looking to add an EG4 18kPV hybrid inverter along with two PowerPro indoor batteries. I'm a bit confused about whether I need a transfer switch for this setup. I thought the inverter might already have a built-in transfer switch. If I do need one, could anyone recommend the right type? Thanks in advance!

It sounds like you might not need a transfer switch at all! What you actually need are disconnects to safely isolate your systems from one another. You can often achieve this by using the breakers you already have. Keep in mind that some setups might require dedicated disconnects depending on your local code, so it's worth checking that.
