SolarEdge Inverters

EXPANDING

SolarEdge Residential Inverter Lineup

Series Power Range Key Features
SE2000H–SE11400H (HD-Wave) 2–11.4 kW Most common residential unit, smaller form factor, higher efficiency
SE3000H–SE7600H (Single Phase) 3–7.6 kW Older residential standard
SE10K–SE33.3K (Three Phase) 10–33.3 kW Commercial applications

LED Indicators

SolarEdge inverters use LED indicators on the front panel for quick status assessment.

LED Color State Meaning
DC Blue On DC input present
Grid Green On Grid connected, system operating
Grid Green Blinking Waking up / anti-islanding check
Grid Red On Grid fault
AC Green On AC output active
Fault Red On Active fault — check SolarEdge GO
Fault Red Blinking Warning — check SolarEdge GO

Display Screen

Newer inverters have a small LCD/LED display panel. Cycle through:

  • Current power output (W or kW)
  • Today's energy (kWh)
  • Lifetime energy (MWh)
  • Grid voltage and frequency
  • Status code

Common Inverter Faults

Fault Likely Cause Action
Grid voltage out of range Utility fluctuation Wait and monitor; call utility if persistent
Isolation fault Wiring insulation issue Full system inspection
Arc fault (AFCI) DC wiring arc detected Inspect all DC wiring before reset
Over-temperature Ventilation blocked, ambient too high Clear airflow obstructions
Ground fault Grounding issue in array Full inspection
Optimizer communication loss RS485 break, optimizer failure See troubleshooting guide

Physical Inspection Checklist

When inspecting a SolarEdge inverter:

  • [ ] Mounting is secure, no movement
  • [ ] Ventilation slots clear of debris and insulation
  • [ ] No signs of moisture ingress or corrosion on housing
  • [ ] DC input wiring is properly dressed, no strain on connectors
  • [ ] AC output connections are tight (visual only unless de-energized)
  • [ ] Conduit entries are sealed against pests
  • [ ] LED indicators are in expected state
  • [ ] Display screen readable (wipe if soiled)
