UnclassifiedCooling
What This Code Means
Equipment has been turned off; Immediate shutdown occurs; System issues an alarm; Operating mode shuts down; Alarm runs continuously; High inverter temperature warning occurs; Output overload warning occurs; System shuts the operating mode down; Error LEDs are on (red); Battery error persists after restarting; Battery state of charge is low (30%, 25%, or 21%); Operating mode will shut down when battery charge reaches 20%; The equipment has shut down; One of the devices assumed the master state; Firmware incompatibility; Equipment shutdown; Inverter error persists; Alarm #14 triggered; Battery error LEDs are on (red)
Possible Causes
- •One of the phases has been turned off
- •One of the inverters turned off during its operation
- •Erroneous synchronization between the inverters
- •Failure of real-time communications
- •High inverter temperature
- •Output overload
- •BMS of the batteries detects that a battery cell has a voltage lower than acceptable
- •Defective battery
- •Deterioration of battery cells
- •Problem in communication in battery modules
- •Low battery state of charge
- •One of the phases has been disabled
- •The original master failed
- •The firmware of one of the connected devices is not up-to-date enough to work with this device
- •Broken maintenance disconnector
- •One of the inverters has stopped working
- •Possible internal battery problem
- •One or more batteries are defective
