reports

c2 drafted · lead Grid instability

affects

c3 drafted · lead Power board

review note: support check: partial - Change power board is a solution, but the board being affected is only implied.

mitigated_by

c4 drafted · lead Inverter restart

c5 drafted · lead Power board replacement

Only if restart does not clear the fault.

has_recovery

c6 drafted · lead Manual reset (operator restarts or acknowledges)

Restart first; power board replacement if persistent.

review note: support check: partial - Restart is the first step, but the passages do not say it clears by manual reset.
