SMA inverter event 6202
Risk level
Critical
Stop using the equipment and contact a professional.
Urgency
Immediate
Quick answer
SMA defines event 6202 as: The inverter detected an internal residual-current monitoring (RCMU/RCD) disturbance and stopped feed-in. The useful next discriminator is event sequence, red-LED state, firmware and diagnostic export. Preserve the event before any reset.
Safety first
What to do now
- Preserve the exact event context
Save event 6202, timestamp, inverter model/serial, firmware, red-LED state, affected phase/string, power and weather before clearing anything.
- Collect one safe discriminator
Record the full event sequence, firmware and LED state. Do not open the inverter or repeat restarts; export diagnostics if the UI allows it. Record event sequence, red-LED state, firmware and diagnostic export; do not change multiple parameters or circuits at once.
- Respect the electrical stop point
If the red LED or event returns, stop cycling power and send the diagnostic package to SMA or a qualified installer.

What a technician must be able to justify
A technician is coming
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.

What they doExport diagnostics, confirm firmware and event sequence, then test the named internal monitoring path through SMA service procedures before considering hardware replacement.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.

What it means
Official meaning: The inverter detected an internal residual-current monitoring (RCMU/RCD) disturbance and stopped feed-in. Decision boundary: capture event sequence, red-LED state, firmware and diagnostic export. Export diagnostics, confirm firmware and event sequence, then test the named internal monitoring path through SMA service procedures before considering hardware replacement.
Warnings and stop conditions
- Criticalsource verified
The inverter contains hazardous stored and live energy. Do not open it or bypass internal protection.
