ABB solar inverter All models error codes
Codes
- E056Error codeExcessive temperature measured inside the inver ter's wiring box: High internal temperature. This error relates to the temperature measured on exter nal boxes (e.g.:TRIO-20.0/27.6kW)
- E057Error codeInput voltage (Vin) higher than booster voltage (Vbulk): The error occurs if the input voltage exceeds the Bulk voltage (voltage on the DC-DC circuit inside the inverter)
- E058Error codeError in the check of Pin vs Pout: The error occurs if the difference between the measured value of input power and that of output power is greater than the limit imposed internally to the inverter
- E077Error codeError inside the inverter
- E078Error codeBefore connection, the inverter made two different Riso circuit self tests: 1. Riso relay self test (displayed as self test 1) 2. Algorithm self test (displayed as self test 2) The inverter failed one of the two RISO tests
- T100Error codeAdhesive PT100 module tem perature sensor (back cell)
- T1000Error codeAmbient temperature sensor with integrated converter
- W001Error codeInsuffci ient sunlight. Wrong confgi uration of the PV array or a confgi uration “at the limit” relative to the minimum input voltage of the inverter
- W002Error codeInsuffci ient sunlight, wrong confgi uration of the photovoltaic array or a confgi uration “at the limit” relative to the minimum input voltage of the inverter
- W003Error codeThis error warning appears during normal inverter operation when the grid parameters fall outside the limits set by the grid company. No grid voltage (after the warning, the inverter goes on “No Vac”). Unstable grid voltage (downwards and upwards). Unstable grid frequency
- W010Error codeFan broken: This error occurs when there is a malfunction in the fan/ fans inside the inverter
- W011Error codeBulk Under-voltage: The alarm (which is a warning and not an error) is gene rated when the voltage at the heads of the bulk capaci tors does not reach the threshold for the operation of the inverter (internal unchangeable threshold)
- W012Error codeBattery fal t: The inverter displays the “Battery fal t” message when it records a voltage for the buffer battery which is too low
- W013Error codeClock broken: The alarm occurs when there is a difference of over 1 minute in the time displayed compared to the internal time of the microprocessors and indicates a malfunction of the clock circuit
- W017Error codeError recorded in measuring string currents: Damaged string protection fuse(s)
- W018Error codeOvervoltage surge arresters situated on the DC side are damaged. (-S1, -S1A and -S1B models only)
- W019Error code(-S1A models only)
- W026Error codeInformation only: AFCI error was cleared
- W027Error codeToo many ground faults detected
