5.3.3.3 Internal Fault Messages

The inverter continually monitors several internal components and will shut

down to help protect itself if one of the following “internal” faults occurs.

Internal Charger appears on the

LCD. The FAULT (red) LED is on. The

PWR (green), CHG (green), and INV

(green) LEDs are off.

Figure 5-36, Internal Charger Fault

• Internal Relay – The inverter shut down because the internal AC

transfer relay did not close while charging.

• Internal Bridge – The inverter shut down because while inverting, the

output circuit is no longer detecting any AC output voltage or current.

• Internal Charger – The inverter shut down because while charging,

the charger circuit is attempting to provide maximum current, but is not

detecting any current or voltage rise to the battery bank.

• Internal NTC – The inverter shut down because the internal NTC

(Negative Temperature Coefﬁ cient) temperature sensor caused a very large

but unexpected temperature change.

Remedy: If an “internal” fault occurs, perform an inverter or power

reset to clear it (see Sections 6.2 & 6.3). After the reset, turn the

inverter on. If the internal fault remains or returns, the inverter will

require repair at an authorized service facility.
