I've got three EG4 Powerpro indoor batteries connected to my Flexboss21, and I've been noticing it seems to reboot about once or twice daily, usually at night when the power briefly goes out. There's nothing in the event logs that indicates why this is happening. Is there a particular setting I should review? Would it help to try isolating my batteries? Just for context, I'm running a soft start on my HVAC system and my daily energy usage is around 35kW.

It sounds like your Flexboss21 might be rebooting due to excessive current draw. When I was running off-grid with two EG4 batteries, I experienced similar issues. Keep in mind that the Flexboss21 only handles about 67 amps of output. If you have something like your HVAC or water heater kicking on at night, that could be pushing the limits. Just a thought, but maybe check your larger appliances while they're drawing power too!
You mentioned your HVAC soft start; is it possible it’s working alongside other high-demand devices? That might overload your system briefly. If you have anything else that uses significant power at night, that might explain the reboots. Double-check how much current your setup is drawing during those spikes.
