# The "_day" sensors are reset to 0 when the inverter wakes up in the morning when the sun comes up and power to the inverter is restored.
# This makes sure daily values are reset at midnight instead of at sunrise.
# When the inverter has a battery connected, HomeAssistant will not reset the values but let the inverter reset them by looking at the unavailable state of the inverter.
