AC Load display very low with ESS on

Added a VM-3P75CT to my MP II 48/3000 split phase system yesterday. Once I got all firmware updated it appeared to be working fine. I installed and configured the ESS assistant and turned peak shaving on. At one point, all looked good and I saw the inverters switch between normal, passthru, and invertering mode depending on load.

This morning I took a look at the remote console and my AC Loads panel is showing very low numbers, like 30W with an AC Input of 778W and 819W being drawn from the battery.

Both "inverters on" lights are blinking (which I believe means "passthru"), both are showing bulk charging on, and one occasionally is showing low voltage, even though battery SOC is 81% and showing 52.9V.

What did I misconfigure?

Found it. Must have accidently toggled "Inverter AC output in use". Turned that back on and all is good.
