I'm working with two MEGAREVO 10kW R10KLNA Hybrid Solar Inverters and I need some help configuring them. My goal is to ensure that no power is sent to the grid when they are connected. I also want the inverters to maintain the battery voltage at 49V when there's low solar input. If the battery reaches 49.5V, I want the grid connection to be turned off. I've checked the CTs and they seem to be functioning correctly, but the setup is quite complex and I could use some tips.

It sounds like you're looking for a zero-export mode. Have you checked if your inverters support any settings for that? Generally, you don't disconnect completely from the grid, and it's essential to establish BMS communication with your batteries. Also, remember to base your logic on battery percentage rather than just voltage.
I think you're on the right track! I found an anti-reverse setting that might help with preventing backfeed to the grid. The manual can be confusing, but I recommend looking specifically for that section!
