High Batt Temp appears on the LCD and the FAULT

INV (green) LEDs are off.
Figure 5-35, High Battery Temperature
• High Battery Temperature (HBatTemp) – This fault message indicates the inverter/charger
has shut down because the Battery Temperature Sensor (BTS) has reached a temp >54°C/129°F.
Remedy: Once the BTS has cooled down (≤49°C/120°F), it automatically restarts and
continues operation. As a precaution, check the BTS location; if placed on a battery,
ensure they are not overheated, or that the BTS hasn’t been placed in a hot area or
near a hot device. If neither of these are the issue, then monitor the BTS meter under
the TECH: 01 INV Temperatures menu. If this reading is above 54°C/129°F, remove the
BTS from the inverter BTS port. If the Batt Temp Sensor reading goes to 25°C/77°F,
replace the BTS. If the reading does not go to 25°C/77°F, then inspect the BTS port for
cleanliness and/or have the inverter/charger serviced.

INV (green) LEDs are off.
Figure 5-36, High Speed Bus Fault
• High Speed Bus (BusFault) – This fault indicates a communication error has occurred between
the inverter’s internal onboard microprocessors. When the unit shuts down because of this fault
condition, perform an inverter reset or power-down the inverter (see Sections 6.2 & 6.3).
Remedy: After performing the reset, turn the inverter on. If the fault does not clear
after the reset, the inverter may require service.
• High Battery (HighBatt) – The inverter has turned off because the battery voltage is at a
very high level. This fault message displays and the FAULT (red) LED turns on when the battery
voltage is above the High Battery Cut-Out (HBCO) value. This fault will automatically restart and
resume operation when the battery voltage drops 0.3 VDC (12-volt models), 0.6 VDC (24-volt
models), or 1.2 VDC (48-volt models) below the HBCO value.
Info: The HBCO value depends on the inverter version and model. Normally, the HBCO
value for modifi ed sine wave inverters (i.e., ME/MM/RD Series) is 16 VDC (12v models)
or 32 VDC (24v models); and, the HBCO value for pure sine wave inverters (i.e., MS/
MMS/MSH Series) is 17 VDC (12v models), 34 VDC (24v), or 68 VDC (48v).
Remedy: This fault usually only occurs when an external DC charging source is charging
the inverter’s battery bank. Turn off any other additional charging source to allow the
DC voltage level to drop.
