Schneider Conext error code F49
DC over-voltage shutdown -- DC voltage is above 35 VDC (24 V) or 70 VDC (48 V). Can occur when batteries are disconnected at the DC breaker while the Conext XW is operating.
What to check, and in what order, is in the app. The flow Coach Electrical — entry diagnostic (converters / inverters / solar / monitors) walks this code step by step with the pass/fail measurements, wiring schematics and procedures that go with it, and it works offline in the bay.
