Do the following:
1. Check whether the grid power supply is off.
2. Check whether any electric device is consuming too much power. If any device is found to be using excessive power, please shut it off.
· Because of the characteristics of battery packs, when the temperature is below 50℉ the system power drops slightly in order to protect the battery life. If the system is found offline or overloaded, you can shut down some high-power devices to ensure the normal functioning.
· If the FHP is offline and overloaded, you will need to shut down electric devices and start them one after another after all aPower X units have been successfully started.
