What does it mean when my SMA SUNNY TRIPOWER CORE1 Inverter detects high direct current in the grid?
If your SMA Inverter displays a grid fault and indicates an excessively high proportion of direct current in the grid current, check the grid connection for direct current. Contact the grid operator and check whether the monitoring threshold on the inverter can be raised.
What does 'Insulation failure' mean on my SMA SUNNY TRIPOWER CORE1 Inverter?
If your SMA Inverter displays 'Insulation failure > Check generator', the inverter has detected a ground fault in the PV array. Check the PV system for ground faults.
What does 'Resid.curr.too.high' mean on my SMA SUNNY TRIPOWER CORE1?
If your SMA Inverter displays 'Resid.curr.too.high > Check generator', the inverter has detected a residual current due to temporary grounding of the PV array. Check the PV system for ground faults.
