Check whether the grid power is down, whether the solar system is out of operation, or there is insufficient sunlight.
1. Low battery and black start indicate that the battery capacity is very low, the backup power and auxiliary power will be disconnected, and the system will enter sleep mode. Once the system enters sleep mode, it will automatically recover and charge the batteries the next day if there is sufficient sunlight.
2. Before the black start, please turn off all household loads to ensure that FHP can be started normally.
3. A Manual black start is an alternative to waiting for the automatic black start.
Manual Start: Turn off the aPower X switch (extended, flush with case) on the side of all aPower X units, wait 20 seconds, then turn on all aPower X batteries. The system will start up.
Attempting a black start will consume the reserve capacity. It is recommended to attempt a manual start only when there is enough solar production. Otherwise, the system may lock.
