Pump is running at low power
during PowerPack operation
Check ambient temperature and ensure that the PowerPack has
proper ventilation

6 Operation
Connect the AC power source and switch on the
PowerPack AFTER it has been connected to the pump
controller. When the controller and the PowerPack
are switched on, the system light should flash on
the controller and the pump should start. When
the PowerPack is switched OFF (or its AC source is
disconnected), the system will run with the PV power
available. If the LED indicator is on this means that
the PowerPack is activated.
