FAULT !
HiBaTemp
• High Battery Temp Fault – 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 has not 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: Bat Tem p menu—this reading should be above
54°C/129°F. Now remove the BTS from the inverter's 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.
FAULT !
High VAC
• High Volts AC Fault – Charger is disabled due to a very high AC voltage
(>150 VAC, >260 VAC – export models) detected on the AC input.
Remedy: Remove all AC power from the inverter's AC input for
at least 15 minutes to automatically restart this fault. Ensure only
120 VAC power is connected to each of the inverter's AC inputs.
Check and correct the high voltage problem from the source.
