None of the following are opposition to your experiment, just explanation and suggestion for caution.
If battery voltage sags under an unanticipated load, inverters can get flakey. Available battery capacity in a used cell DIY system is often underestimated in practice. One frequent source of surging loads is refrigerator start.
Modern refrigerators can be quite sensitive to power parameters and are expensive to replace. Generally householders (like myself) do want refrigeration to continue in a power outage, since food can get ruined. Brief power outages are mere inconvenience. Extended ones are the ones I want a backup system to get through.
I use Kill-A-Volt as a frequency monitor, plugged into a wall circuit, during a power outtage when I'm on generated power. It once saved me a LOT of money when the generator's power regulator circuitry malfunctioned. Inverters can fail as well.
