AC300 No AC after drained batteries

AC300’s with 4xB300s each. Set to operate as standard UPS
Scenario: Utility power off → batteries kick in → batteries drained → all is off…-> utility comes back on. Utility power is not routed back through AC300 outlets !!! How come ?

Hi @BigApple , Since the UPS situation you described has the machine shut down after the battery is depleted, our machine has to be turned on manually after it is shut down.
It can only be turned on automatically if there is PV input.

So if the Utility power comes back on… it does nothing ? it wont recharge itself either as it is completely non functional ? only if i have Solar.? so using this as a UPS with Utility power only is limited as you have to be home to turn it back on ? I have devices that turn itself back on when the power gets restored … why would you not make these units one of them as they seem to need it… Or at least have it passthrough the Utility power when the unit is off this way at least the power is back for the house when the unit is off. it seems to make things worse rather then help.

Hi @BigApple , When the battery is depleted and the utility power is restored, you need to turn on the machine by yourself.
Unless you connect the solar panel, there is PV input to make the machine turn on automatically.
