5.0 Operation

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.

High Batt Temp appears on the

• 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.

• 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.
