Photovoltaic Solar Inverter Series ES Status diagnosis and troubleshooting 9. Status diagnosis and troubleshooting The PV solar inverter is equipped with a self-diagnosis system that identifies a large number of possible operating conditions independently and shows them on the LCD display. This makes it possible to quickly eliminate technical prob- lems. Furthermore, a distinction is possible between o service codes concerning installation and o service codes that relate internally to the PV solar inverter. Whenever the self-diagnosis system identifies a particular problem, the corre- sponding service code is showed on the LCD display. Information! The following work may only be performed by trained technical staff. 9.1 Error codes and explanations LCD display Description Explanation Troubleshooting Er00 DC _BUS pre-charge defect Er03 Inverter voltage abnormal Er07 DC_BUS over-voltage Er08 DC_BUS under-voltage Er19 DC_BUS discharge defect Er22 Output relay defect The device is in the soft start mode, but after 2 seconds you do not see any stable charging voltage on the DC bus. The output voltage is not correct. The internal voltage of the DC bus is outside the tolerance. The capacitors of the DC bus cannot be discharged correctly. Malfunction on the output relay of the solar inverter. 1 Disconnect all PV(+) - or PV(-) connections. 2 Wait a few seconds. 3 After the LCD display goes out, reinsert all the connections and check it again. 4 If the error still occurs, please contact your dealer. 1. Disconnect all PV(+) - or PV(-) connections. 2. Wait a few seconds. 3. After the LCD display ES series 48
Photovoltaic Solar Inverter Series ES Status diagnosis and troubleshooting LCD display Description Explanation Troubleshooting Er24 Output current sense defect Er25 BOOSTER_A over-current Er26 BOOSTER_B over-current Er29 PV inverter output DC current over spec. Error in the output current reading. The current in the DC mains is higher than expected. DC current at output of solar inverter is too high. Er06 EPO The PV solar inverter is in the emergency power off mode. Er09 PV inverter over-current Er11 PV inverter over-load Er13 PV inverter short-circuit Er14 PV inverter PLL defect Er10 PV inverter over temperature Er18 Heatsink over temperature Over-current on the AC side. The current in the AC mains is higher than expected. Over-load on the AC side. The mains load in the AC mains is higher than expected. Short circuit on the AC side. The PV solar inverter is not in phase with the mains electricity. The internal temperature is too high. The temperature on the cooling element is too high. switches off, reinsert all the connections and check it again. 4. If the error still occurs, please contact your dealer. 1. Detach the connection at the EPO connection. 2. If the error still occurs, please contact your dealer. 1. Turn off the AC current switch; check the peripheral AC current system configurations and the mains conditions. 2. If the error still occurs, please contact your dealer. 1. Try to reduce the surrounding tempera- ES series 49 ture. 2. Install the solar inverter in a cooler place. 3. If the error still occurs, please contact your dealer.
