CMS 1500 and CMS 2000 Fault and Error Messages
Message in English
System Fault & Error Messages
|Isolation fault||Isolation failure||Earth fault on the solar panels or failure of surge protection|
|Ground I Fault||GFCI active||Leakage current to ground is too high|
|Grid fault||Grid failure||Grid measured data is beyond the specification (voltage & frequency)|
|No utility||No utility||Utility is not available|
|PV over voltage||Input voltage too high||Input voltage from the solar panels higher than the max input voltage|
Inverter Fault and Error Messages
|Consistent fault||Consistent failure||The readings of 2 microprocessors are not consistent. CPU and/or other circuit not functioning may be the cause.|
|Over temperature||Temperature too high||The internal temperature is higher than the normal value|
|Relay failure||Output relay failure||The relay between the inverter and grid is not functional|
|DC INJ High||Output DC injection too high||Output DC injection is too high|
|EEPROM failure||EEPROM problem||EEPROM inside the inverter has a data access problem|
|SCI failure||Problem with communication between microprocessors||The communication between MCU inside the inverer is abnormal|
|High DC Bus||DC bus voltage is too high||The DC Bus inside is higher than expected|
|Low DC Bus||DC bus voltage is too low||The DC bus inside is lower than expected|
|Ref 2.5V Fault||2.5V reference voltage inside problem||The 2.5V reference inside the inverter is abnormal|
|DC Sensor Fault||Output DC sensor abnormal||The DC output sensor is abnormal|
