Which SolarEdge errors clear themselves and which need an engineer?

Short answer

SolarEdge grid-voltage, grid-frequency and grid-down codes (2x1F, 2x20, 2x28 and 18x40 upwards) clear once the grid is back within limits. Night mode (2x2/18x3) is normal after dark. Isolation, ground-current, arc, relay, DC over-voltage, 'device locked' and hardware (RMA) codes need a PV installer. Homeowners should only check breakers and note the code.
