Configuration of the Xanbus AGS

IMPORTANT: If quiet time is set for overnight, be aware that overnight battery drain can be significant as it may be necessary to use the inverter and batteries to supply AC Power without the help of a generator.

Therefore, it is important to conserve battery power during this time. Minimize the use of interior lights and set thermostat temperature lower to prevent the furnace from coming on at night during cool weather. Set thermostats higher to prevent air conditioning coming on at night during warm weather.

Sometimes automatic start or automatic stop triggers may overlap with the beginning and end of quiet time. Three different quiet time scenarios affect when the generator stops and starts.

1.If quiet time begins after the AGS has started the generator, the generator will stop. If the condition that started the generator is still present when quiet time ends, the generator will restart.

2.If a condition that requires starting the generator occurs during quiet time, the AGS will ignore it until quiet time ends. If the condition still exists at the end of quiet time, the AGS will start the generator.

3.If the running generator stops when quiet time begins and a condition that requires stopping the generator occurs during quiet time, the generator will not restart when quiet time ends.
