Figure 5-22, High Battery Fault

• High Battery – The inverter has turned off because the battery voltage
is at a very high level. The fault occurs when the battery voltage is above the
High Battery Cut-Out (HBCO) value. The inverter 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 is dependent on your inverter revision and
model. Normally, the HBCO value for ME/MM/RD Series inverters is
preset to 16 VDC (12-volt models) or 32 VDC (24-volt models). The
HBCO value for MS/MMS Series inverters is preset to 17 VDC (12-
volt models), 34 VDC (24-volt models), or 68 VDC (48-volt models).
Remedy: This fault usually occurs when an external DC source is
charging the inverter's battery bank. Turn off any other additional
charging source to allow the DC voltage level to drop.

Figure 5-23, High Battery Temperature Fault

• High Battery Temperature – This fault message indicates the inverter/
charger has shut down because the Battery Temperature Sensor (BTS) has
reached a temperature greater than 54°C/129°F.
Remedy: Once the BTS cools 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 display under
the TECH/01 Temperatures menu—this reading should be above
54°C/129°F. Now remove the BTS from the inverter BTS port. If
the BTS 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.
