Product Introduction Intended Usage SG25CX-SA, a transformerless three-phase PV grid-connected inverter, is an integral component in the PV power system. The inverter is designed to convert the direct current power generated from
You may get additional information at This manual is for technical personnel who are responsible for inverter installation, operation and maintenance, and the inverter owner who will perform daily APP operation. Read the manual and other related documents before commencing any work on the inverter.
Measure the actual grid, and contact the local electric power company for solutions if the grid Grid Abnormal parameter exceeds the set range. 2. Contact Sungrow Customer Service if the preceding causes are ruled out and the fault persists. Generally, the inverter will be reconnected to the grid after the grid returns to normal.
10-minute grid overvoltage, the grid voltage 014 exceeds the preset AC voltage of the inverter for a long time. Wait for the inverter to return to normal. Disconnect the AC and DC switches, and reconnect the AC and DC switches 15 minutes later to restart the inverter. If the fault still exists, contact Sungrow Service.
