To accommodate these situations, the automatic Neutral-to-Ground Connection system can be deactivated,
so it will not bond the neutral in any mode of operation.
If you are not sure whether you must disable this feature, please refer to your local code requirements or
contact us at info@sigineer.com for details.
There is a section of green wire with the insulated connector at the left side of the AC terminal block. This
insulated connector connects the neutral and ground inside the inverter while inverting.
Pull the two ends of the insulated connector apart to separate the green wire; this will prevent the neutral and
ground from connecting inside this inverter.
If possible, use electrical tape to insulate the disconnected ends, move the two ends away from each other
and push back out of the way. Typically when connecting to a house panel (after disconnecting city power
from it) , you would disconnect this connection as a house panel already has the neutral to ground bond.
Typically in a standalone system or in a vehicle, you would want to keep this connection.
NOTE: The PSW71512NC and PSW1524NC inverter chargers are built with automatic neutral to ground
bonding without cable connectors on the AC terminal block, this feature can’t be deactivated.
2.5.15 Lithium Battery Wakeup
Lithium-ion battery will enter sleep mode when it is overdischarged. When the protection circuit is triggered,
the voltage could drop to 0Vdc.
Such batteries are assumed useless to most competing inverter chargers which require a minimal DC voltage
to power on.
This makes it possible for a charger to charge ordinarily.
The whole line of Sigineer Power inverters will use AC input power to wake up overdischarged lithium
battery by a boost circuitry.
When they detect a 0V battery, the charger will output a small current to awaken the lithium batteries.
